    Gulf War illnesses (GWI share many of the features of chronic fatigue syndrome (CFS) and both CFS and GWI may be the result of chronic immune system processes. The main suspected cause for GWI, the drug pyridostigmine bromide (PB), has been shown to cause neuronal damage from reactive oxygen species (ROS). ROS have been associated with IgM mediated autoimmune responses against ROS induced neoepitopes in depressed patients and this may also apply to CFS. It therefore follows that the drug used in the Gulf War caused ROS, the ROS modified native molecules, and that this trigged the autoimmune condition we refer to as Gulf War illnesses. Similar mechanisms may apply to other autoimmune illnesses. Copyright © 2012 Elsevier Ltd. All rights reserved.

  2. A diverse group of previously unrecognized human rhinoviruses are common causes of respiratory illnesses in infants.

    Full Text Available Human rhinoviruses (HRVs are the most prevalent human pathogens, and consist of 101 serotypes that are classified into groups A and B according to sequence variations. HRV infections cause a wide spectrum of clinical outcomes ranging from asymptomatic infection to severe lower respiratory symptoms. Defining the role of specific strains in various HRV illnesses has been difficult because traditional serology, which requires viral culture and neutralization tests using 101 serotype-specific antisera, is insensitive and laborious.To directly type HRVs in nasal secretions of infants with frequent respiratory illnesses, we developed a sensitive molecular typing assay based on phylogenetic comparisons of a 260-bp variable sequence in the 5' noncoding region with homologous sequences of the 101 known serotypes. Nasal samples from 26 infants were first tested with a multiplex PCR assay for respiratory viruses, and HRV was the most common virus found (108 of 181 samples. Typing was completed for 101 samples and 103 HRVs were identified. Surprisingly, 54 (52.4% HRVs did not match any of the known serotypes and had 12-35% nucleotide divergence from the nearest reference HRVs. Of these novel viruses, 9 strains (17 HRVs segregated from HRVA, HRVB and human enterovirus into a distinct genetic group ("C". None of these new strains could be cultured in traditional cell lines.By molecular analysis, over 50% of HRV detected in sick infants were previously unrecognized strains, including 9 strains that may represent a new HRV group. These findings indicate that the number of HRV strains is considerably larger than the 101 serotypes identified with traditional diagnostic techniques, and provide evidence of a new HRV group.

    We studied the distribution of deaths from ill-defined causes that occurred in Brazil during 2003, from which was identified the proportion of unattended deaths. Data were obtained from the Mortality Information System, coordinated by the Ministry of Health. Causes of death included in "Chapter XVIII - Symptoms, signs and abnormal clinical and laboratory findings, not classified elsewhere" of the International Statistical Classification of Diseases and Related Health Problems, tenth revision, were considered ill-defined, among which the category R98 identified "unattended deaths". In Brazil during 2003 the underlying causes of 13.3% of deaths were included in the Chapter of ill-defined causes, and the highest proportions of these deaths occurred in the Northeast and North Regions. Considering the total deaths from ill-defined causes, 53 % correspond to unattended deaths. This proportion increased to over 70% in the states of Maranhão, Piauí, Rio Grande do Norte, Pernambuco, Bahia, Paraíba and Alagoas. Due to the decentralized structure of data collection in the country, we believe that the municipalities bear the major responsibility, followed by the states, for upgrading the quality of mortality statistics.

    The concept of aetiology of mental illness in 134 Malay patients was investigated by means of a 20-item checklist. About 53% of the patients attributed their illnesses to supernatural agents. Witchcraft and possession by evil spirits were regarded as common causes of illness. The number of patients who believed in supernatural causes of their mental illness was significantly higher among those who had consulted bomohs (Malay traditional healers) than among those who had not consulted them. The belief that mental illness is caused by supernatural agents is firmly held by bomohs, who reinforce this notion in those who seek their advice. Belief in supernatural causes of mental illness was not significantly associated with age, gender, level of education or occupation of the patients. Patients who believed in supernatural causes of mental illness were also found to show poor drug compliance, and the number of such patients at 6 months follow-up was significantly lower than the corresponding figure for those who did not believe in supernatural causes. The importance of understanding the patients' cultural background when treating psychiatric patients is highlighted.

    Three outbreaks of respiratory illness associated with human coronavirus HCoV-OC43 infection occurred in geographically unrelated aged-care facilities in Melbourne, Australia during August and September 2002. On clinical and epidemiological grounds the outbreaks were first thought to be caused by influenza virus. HCoV-OC43 was detected by RT-PCR in 16 out of 27 (59%) specimens and was the only virus detected at the time of sampling. Common clinical manifestations were cough (74%), rhinorrhoea (59%) and sore throat (53%). Attack rates and symptoms were similar in residents and staff across the facilities. HCoV-OC43 was also detected in surveillance and diagnostic respiratory samples in the same months. These outbreaks establish this virus as a cause of morbidity in aged-care facilities and add to increasing evidence of the significance of coronavirus infections. PMID:15816152

    Stigma among health care providers toward people with mental illness is a worldwide problem. This study at a large US university examined medical student attitudes toward mental illness and its causes, and whether student attitudes change as they progress in their education. An electronic questionnaire focusing on attitudes toward people with mental illness, causes of mental illness, and treatment efficacy was used to survey medical students at all levels of training. Exploratory factor analysis was used to establish attitudinal factors, and analysis of variance was used to identify differences in student attitudes among these factors. Independent-samples t tests were used to assess attitudes toward efficacy of treatments for six common psychiatric and medical conditions. The study response rate was 42.6 % (n = 289). Exploratory factor analysis identified three factors reflecting social acceptance of mental illness, belief in supernatural causes, and belief in biopsychosocial causes. Stages of student education did not differ across these factors. Students who had completed the psychiatry clerkship were more likely to believe that anxiety disorders and diabetes could be treated effectively. Students reporting personal experiences with mental illness showed significantly more social acceptance, and people born outside the USA were more likely to endorse supernatural causes of mental illness. Sociocultural influences and personal experience with mental illness have a greater effect than medical education on attitudes toward people with mental illness. Psychiatric education appears to have a small but significant effect on student attitudes regarding treatment efficacy.

    Full Text Available Objectives: Several epidemiological studies on medical care utilization prior to suicide have considered the motivation of suicide, but focused on the influence of physical illnesses. Medical care expenditure in suicide completers with non-illness-related causes has not been investigated. Methods: Suicides motivated by non-illness-related factors were identified using the investigator’s note from the National Police Agency, which was then linked to the Health Insurance Review and Assessment data. We investigated the medical care expenditures of cases one year prior to committing suicide and conducted a case-control study using conditional logistic regression analysis after adjusting for age, gender, area of residence, and socioeconomic status. Results: Among the 4515 suicides motivated by non-illness-related causes, medical care expenditures increased in only the last 3 months prior to suicide in the adolescent group. In the younger group, the proportion of total medical expenditure for external injuries was higher than that in the older groups. Conditional logistic regression analysis showed significant associations with being a suicide completer and having a rural residence, low socioeconomic status, and high medical care expenditure. After stratification into the four age groups, a significant positive association with medical care expenditures and being a suicide completer was found in the adolescent and young adult groups, but no significant results were found in the elderly groups for both men and women. Conclusions: Younger adults who committed suicide motivated by non-illness-related causes had a higher proportion of external injuries and more medical care expenditures than their controls did. This reinforces the notion that suicide prevention strategies for young people with suicidal risk factors are needed.

    Full Text Available In Byzantium mentally ill persons were stigmatized, despite the fact that they could live normally. This stigma consisted a very serious problem not only for the patients themselves, but also for their families.Through the legislation of the Byzantine Emperor Justinian and also the Leo's VI the Wise (9th – 10th A.C. legislation, mental illness was a main health cause of divorce and it concerned both males and females.During these years men were treated different than women, which had to wait five years in order to get a divorce. On the opposite men had to wait only three years to get a divorce for the cause of mentally retarded wife.

    a range of psychiatric illnesses in both sexes. We observed SMRs greater than 200 in men and women with alcoholism, drug abuse, organic psychoses, dementia, and learning difficulties. Alcoholism and drug misuse in particular were important causes of premature mortality. The highest cause-specific SMRs...... were for nervous system diseases, gastrointestinal diseases, lung diseases, and "all other natural causes"; the lowest were for neoplasm. The greatest excess, in terms of absolute numbers, was for circulatory disease mortality. CONCLUSION: Adults experiencing a range of psychiatric illnesses are more...... likely to die at any age, and also prematurely, from natural causes. The consistency of elevated risk across psychiatric diagnoses and causes of death indicates an important health inequality. Those involved in planning and providing mental health services should address the heightened need for physical...

  11. Physics of Intrinsic and Extrinsic Factors that Cause the Onset of the Deadliest Illness of Mankind and are Important for Diagnostics and Treatment

    Science.gov (United States)

    Saxena, Arjun

    One of the most important topic of research in the field of Physics of Behavior is the deadliest illness of mankind which is the group of illnesses called mental illnesses. They are getting attention increasingly worldwide by the medical communities and their respective governments, because of the following fact. It is now well established that these illnesses cause more loss of human lives, destruction of families, businesses and overall economy than all the other illnesses combined. The purpose of this paper is to identify and provide solutions to two fundamental issues of such illnesses which still remain as problems. One is the stigma associated with them because of their name ``mental''. The patients are regarded as less than normal because their illness is only ``mental'' in origin. The second is that it is still not widely recognized that they are caused by medical problems in their ``brain'' which afflict their ``mind''. This paper explains this and gives an improved 3-D model using the physics of intrinsic and extrinsic factors of both ``brain'' and ``mind''. It leads to an important new name, ``BAMI'' (Brain and Mind Illness), which eliminates the stigma and gives quantitative parameters to diagnose the illness and monitor medicines to treat such illnesses.

  12. Descriptive survey about causes of illness given by the parents of children with cancer.

    When a doctor diagnoses a child's illness as cancer, parents very often react by creating wrong and unrealistic theories about the origins of their child's illness which in turn generates self-blame in the parents, who take responsibility for the disease. To find what are the parents' beliefs about the origins of their children's illness. Descriptive study. Seventy-two couples of parents whose children with cancer are under treatment in the haemato-oncology paediatric ward of the Padova hospital. They have been collected by a no probabilistic method of sampling. A questionnaire was used, based on current literature, which investigates the beliefs of the parents as to what are the causes of illness, whether the parents research information about the illness and the origins of cancer and what are the information sources they use in order to establish if there is a connection between these factors. Eighty-seven percent of the sample group thinks that there is a specific origin of their child's illness: 27% believes the cause is environmental pollution, 26% believes it is due to radiation emissions, 26% believes it is due to genetic factors and 8% believes it is due to other causes. Eighty six percent and 70% of the sample search for information about the illness and its causes; 64% of the parents state that the first meeting with the medical staff, in which the illness is explained and they are informed that there are no known causes that produce it, does not clarify their doubts. The sources more often used to search for more information and explanations are the physicians in the ward, internet and medical books. This survey confirms the importance of an "advocacy" role of the nurse in educating the caregiver and the need to create instruments which guide the parents in the informative process and the research for good information. Nurses need to be cognizant that their care is crucial not just for the child, but for the entire family.

    Patients with multiple sclerosis (MS) experience higher mortality rates as compared to the general population. While the risk of intensive care unit (ICU) admission is also reported to be higher, little is known about causes of death CoD in critically ill MS patients. To study the causes of death (CoD) in the series of critically ill patients with MS verified by autopsy. We reviewed hospital electronic charts of MS patients treated at the neurological ICU of a tertiary care hospital between 2000 and 2015. We compared clinical and pathological CoD for those who were autopsied. Overall, 10 patients were identified (seven female; median age at death 65 years, range 27-80), and six of them were autopsied. The median MS duration prior to ICU admission was 27.5 years (range 1-50), and the median EDSS score at the time of ICU admission was 9 (range 5-9.5). The median length of ICU stay was 3 days (range 2-213). All the individuals in our series had experienced respiratory insufficiency during their ICU stay. The autopsy examination of brain tissue did not reveal evidences of MS lesions in one patient. In another patient, Lewy bodies were found on brain immunohistochemistry. Mortality in critically ill MS patients is largely driven by respiratory complications. Sporadic disparities between clinical and pathological findings can be expected. © 2016 John Wiley & Sons A/S.

    This study examined beliefs about the causes and determinants of health, illness, and recovery in an opportunistic sample from Malaysia. In all, 371 women and 350 men completed the Health and Illness Scale, a 124-item scale that examined beliefs about current and future health, and beliefs about the causes of illness and recovery. Each of the four subscales of the Health Illness Scale were factor analysed to reveal the underlying structure. Results showed the emergence of a number of distinct factors in the case of each subscale, of which environmental, life-style, psychological, religious, and fate-related factors were fairly stable across subscales. Results also showed a number of differences in beliefs between religious groups, and that religiosity and sex were the strongest predictors of beliefs across the four subscales. The results are discussed in terms of the available cross-cultural literature on lay beliefs about health.

  16. Dorothea dix: A proponent of humane treatment of mentally ill

    2016-01-01

    Full Text Available The work of early pioneers like Dorothea Dix was instrumental in the establishment of institutions dedicated especially for the care of the mentally ill. Originally from the United States, she became acquainted with the idea of humane treatment of the mentally ill during her visit to England. After her return to the United States, she conducted a statewide investigation of care for the insane poor in Massachusetts and began to extensively lobby for reforms and establishment of more state-funded institutions for the care of mentally ill. Her efforts led to setting up of several mental health institutions, which became the cornerstone of care of psychiatrically ill, and for training of mental health care providers. Though subsequently, the hegemony of the institutions was challenged, and the era of deinstitutionalization was ushered in, the work of Dorothea Dix is important as it vouched for humane care of patients with mental illnesses.

    An epidemic of rash and fever illnesses suspected of hand, foot and mouth disease (HFMD) occurred in Gansu Province of China in 2008, laboratory tests were performed in order to identify the pathogen that caused this epidemic. Eight clinical specimens collected from the 4 patients (each patient has throat swab and herpes fluid specimens) with rash and febrile illness, were inoculated onto RD and HEp-2 cells for virus isolation, and the viral nucleic acid was then extracted with the positive virus isolates, the dual-channel real-time reverse transcript-polymerase chain reaction (RT-PCR) was performed to detect the nucleic acid of human enterovirus (HEV) in the viral isolates at the same time. For the viral isolates with the negative results of HEV, a sequence independent single primer amplification technique (SISPA) was used for "unknown pathogen" identification. Totally, 6 viral isolates were identified as herpes simplex virus type 1 (HSV-1). Comprehensive analyses results of the clinical manifestations of the patients, epidemiological findings and laboratory test indicated that this epidemic of rash and febrile illness was caused by HSV-1. The differences among the gG region of 6 HSV-1 isolates at nucleotide level and amino acid level were all small, and the identities were up to 98. 8% and 97.9%, respectively, showing that this outbreak was caused by only one viral transmission chain of HSV-1. HSV-1 and other viruses that cause rash and febrile illnesses need differential diagnosis with HFMD. The etiology of rash and febrile illness is sometimes difficult to distinguish from the clinical symptoms and epidemiological data, the laboratory diagnosis is therefore critical.

    Stigma towards people with mental illness remains a burden for patients and healthcare providers. This study at a large US university examined the attitudes of psychiatry residents and fellows towards mental illness and its causes, and whether their attitudes differed from the medical student attitudes previously studied utilizing the same survey method. An electronic questionnaire examining attitudes toward people with mental illness, causes of mental Illness, and treatment efficacy was used to survey the attitudes of psychiatry residents and fellows. Exploratory factor analysis derived from the authors' medical student survey was used to examine attitudinal factors. The study response rate was 54.2% (n = 94). Factor analysis employed three factors previously identified reflecting social acceptance of mental illness, belief in supernatural causes, and belief in biopsychosocial causes. Residents and fellows reporting more personal experiences with mental illness, both as a group and when compared with medical students, were significantly more willing to socialize with the mentally ill. Respondents who had more professional (work) experience other than medical school or post-graduate training were less likely to believe in supernatural causes of mental illness. Female residents and fellows were more willing to socialize with the mentally ill, and were less likely to believe in supernatural causes for mental illness than their male counterparts. In our study, increased social acceptance of the mentally ill relates to having personal experiences, advanced training in psychiatry, and female gender. Both professional experiences outside of training and female gender reduced the belief in supernatural causes.

    Cyanobacteria, also known as blue-green algae, are photosynthetic, aquatic organisms found in fresh, brackish, and marine water around the world (1). Rapid proliferation and accumulation of potentially toxin-producing cyanobacteria characterize one type of harmful algal bloom (HAB). HABs have the potential to cause illness in humans and animals (2,3); however, the epidemiology of these illnesses has not been well characterized. Statewide in 2015, a total of 139 HABs were identified in New York, 97 (70%) of which were confirmed through laboratory analysis; 77 independent beach closures were ordered at 37 beaches on 20 different bodies of water. To better characterize HAB-associated illnesses, during June-September 2015, the New York State Department of Health (NYSDOH) implemented a pilot surveillance system in 16 New York counties. Activities included the collection of data from environmental HAB reports, illness reports, poison control centers, and syndromic surveillance, and increased outreach to the public, health care providers, and veterinarians. During June-September, 51 HAB-associated illnesses were reported, including 35 that met the CDC case definitions*; 32 of the cases occurred in humans and three in dogs. In previous years, New York never had more than 10 HAB-associated illnesses reported statewide. The pilot surveillance results from 16 counties during a 4-month period suggest that HAB-associated illnesses might be more common than previously reported.

    Individuals with mental illness commonly experience human rights violations while seeking to meet their basic needs. There is lack of research in developing countries on gender-related differences in human rights needs. This study investigated gender differences in perceived human rights needs at the family and community levels in individuals with mental illness in India. This descriptive study surveyed 100 asymptomatic individuals with mental illness at a tertiary care center. Subject selection employed a random sampling method. Data were collected using face-to-face interviews based on a structured needs assessment questionnaire. Data were analyzed and interpreted using descriptive and inferential statistics. Subjects enjoyed a satisfactory level of fulfillment in the physical dimension of human rights needs, which included food, housing, and clothing. Men expressed lower satisfaction than women with perceived human rights needs fulfillment in the emotional dimension. This included fear of family members (χ = 9.419, p human rights needs fulfillment in social and ethical dimensions. The former included freedom to leave the home (χ = 11.277, p human rights needs of people with mental illness and that legislation must be strengthened to meet the human rights needs of this disadvantaged population.

    Human rights violations are commonly reported against people with mental illness and have remained a major research issue in recent times. The present study was aimed to compare psychiatric patients' perceptions of human rights needs between rural and urban settings. A descriptive study design was carried out among 100 recovered psychiatric patients based on the Clinical Global Impression-Improvement Scale (CGI-I scale), at a tertiary care center. Participants were selected through a random sampling method. Data was collected through face to face interviews, using a structured questionnaire. Data was analyzed and interpreted using descriptive and inferential statistics. The present study highlighted the significant differences in meeting their basic human rights needs in a physical needs dimension i.e. availability of hot water for bathing (c2=8.305, p .019). Our findings revealed that human rights violations among mentally ill are evident across rural and urban environments. Thus, there is an urgent need to change the attitude of the general population towards people with mental illness through awareness campaign. In addition, educating the public about the human rights of mentally ill is also essential.

  3. Functional status and all-cause mortality in serious mental illness.

    Full Text Available Serious mental illness can affect many aspects of an individual's ability to function in daily life. The aim of this investigation was to determine if the environmental and functional status of people with serious mental illness contribute to the high mortality risk observed in this patient group.We identified cases of schizophrenia, schizoaffective and bipolar disorder aged ≥ 15 years in a large secondary mental healthcare case register linked to national mortality tracing. We modelled the effect of activities of daily living (ADLs, living conditions, occupational and recreational activities and relationship factors (Health of the Nation Outcome Scale [HoNOS] subscales on all-cause mortality over a 4-year observation period (2007-10 using Cox regression.We identified 6,880 SMI cases (242 deaths in the observation period. ADL impairment was associated with an increased risk of all-cause mortality (adjusted HR 1.9; 95% CI 1.3-2.8; p = 0.001, p for trend across ADL categories = 0.001 after controlling for a broad range of covariates (including demographic factors, physical health, mental health symptoms and behaviours, socio-economic status and mental health service contact. No associations were found for the other three exposures. Stratification by age indicated that ADLs were most strongly associated with mortality in the youngest (15 to <35 years and oldest (≥ 55 years groups.Functional impairment in people with serious mental illness diagnoses is a marker of increased mortality risk, possibly in younger age groups as a marker of negative symptomatology.

    People with mental illness are vulnerable to human rights violations and people with illiteracy and mental illness are at a double disadvantage. To determine the role of education in ascertaining human rights needs of people with mental illness. This was a descriptive study carried out among randomly selected (N = 100) recovered psychiatric patients with mental illness in the past based on the Clinical Global Impression-Improvement scale at a tertiary care centre. Data were collected through face-to-face interview using structured needs assessment questionnaire comprising two sections related to family and community domains. Data were analysed and interpreted using descriptive and inferential statistics. Our findings revealed that human rights needs in the physical needs dimension--i.e., access to electricity (χ2 = 5.523, p < .019) and safe drinking water facilities (χ2 = 9.665, p < .022)--were rated higher in illiterates than in literates. The human rights needs in emotional dimension - i.e. feeling separated from their families because of their illness (χ2 = 13.118, p < .004), afraid of family members (χ2 = 13.388, p < .004) and called filthy nicknames (χ2 = 17.759, p < .000) - were rated higher in literates than in illiterates. The human rights needs in the religious needs dimension - i.e. allowed to go to temple, church, mosque etc. (χ2 = 12.000, p < .007) - and in the social needs dimension - i.e. friendliness with family members -were rated higher in illiterates than in literates (χ2 = 9.661, p < .022). Empowering people with mental illness by providing adequate opportunity to pursue education will play an important role in fulfilling the obligation of the United Nations Convention on the Rights of Persons with Disabilities.

    Full Text Available Abstract Background Although attention to human rights in Indonesia has been improving over the past decade, the human rights situation of persons with mental disorders is still far from satisfactory. The purpose of this paper is to examine the legal framework for protection of human rights of persons with mental disorder and the extent to which Indonesia's international obligations concerning the right to health are being met. Methods We examined the Indonesian constitution, Indonesian laws relevant to the right to health, the structure and operation of the National Human Rights Commission, and what is known about violations of the human rights of persons with mental illness from research and the media. Results The focus of the Indonesian Constitution on rights pre-dated the Universal Declaration, Indonesia has ratified relevant international covenants and domestic law provides an adequate legal framework for human rights protections. However, human rights abuses persist, are widespread, and go essentially unremarked and unchallenged. The National Human Rights Commission has only recently become engaged in the issue of protection of the rights of persons with mental illness. Conclusion More than legislation is needed to protect the human rights of persons with mental illness. Improving the human rights situation for persons with mental illness in Indonesia will require action by governments at national, provincial and district levels, substantial increases in the level of investment in mental health services, coordinated action by mental health professionals and consumer and carer organisations, and a central role for the National Human Rights Commission in protecting the rights of persons with mental illness.

    Background Although attention to human rights in Indonesia has been improving over the past decade, the human rights situation of persons with mental disorders is still far from satisfactory. The purpose of this paper is to examine the legal framework for protection of human rights of persons with mental disorder and the extent to which Indonesia's international obligations concerning the right to health are being met. Methods We examined the Indonesian constitution, Indonesian laws relevant to the right to health, the structure and operation of the National Human Rights Commission, and what is known about violations of the human rights of persons with mental illness from research and the media. Results The focus of the Indonesian Constitution on rights pre-dated the Universal Declaration, Indonesia has ratified relevant international covenants and domestic law provides an adequate legal framework for human rights protections. However, human rights abuses persist, are widespread, and go essentially unremarked and unchallenged. The National Human Rights Commission has only recently become engaged in the issue of protection of the rights of persons with mental illness. Conclusion More than legislation is needed to protect the human rights of persons with mental illness. Improving the human rights situation for persons with mental illness in Indonesia will require action by governments at national, provincial and district levels, substantial increases in the level of investment in mental health services, coordinated action by mental health professionals and consumer and carer organisations, and a central role for the National Human Rights Commission in protecting the rights of persons with mental illness.

    Full Text Available Rhodotorula spp . are common saprophytes but may be responsible for systemic infections in immunocompromised patients. Meningitis caused by Rhodotorula spp. in human immunodeficiency virus (HIV infected patients has been reported only rarely. We present a case of meningitis caused by Rhodotorula rubra in HIV infected patient. The presumptive diagnosis of cryptococcal meningitis was made on the basis of India ink preparation, Gram staining and latex agglutination test (LAT for cryptococcal antigen. The final diagnosis was confirmed by isolation of Rhodotorula rubra from cerebrospinal fluid on culture. LAT was considered false positive. Amphotericin B and 5-fluorocytosine were administered but the patient succumbed to his illness.

  11. The dappled nature of causes of psychiatric illness: replacing the organic-functional/hardware-software dichotomy with empirically based pluralism.

    Science.gov (United States)

    Kendler, K S

    2012-04-01

    Our tendency to see the world of psychiatric illness in dichotomous and opposing terms has three major sources: the philosophy of Descartes, the state of neuropathology in late nineteenth century Europe (when disorders were divided into those with and without demonstrable pathology and labeled, respectively, organic and functional), and the influential concept of computer functionalism wherein the computer is viewed as a model for the human mind-brain system (brain=hardware, mind=software). These mutually re-enforcing dichotomies, which have had a pernicious influence on our field, make a clear prediction about how 'difference-makers' (aka causal risk factors) for psychiatric disorders should be distributed in nature. In particular, are psychiatric disorders like our laptops, which when they dysfunction, can be cleanly divided into those with software versus hardware problems? I propose 11 categories of difference-makers for psychiatric illness from molecular genetics through culture and review their distribution in schizophrenia, major depression and alcohol dependence. In no case do these distributions resemble that predicted by the organic-functional/hardware-software dichotomy. Instead, the causes of psychiatric illness are dappled, distributed widely across multiple categories. We should abandon Cartesian and computer-functionalism-based dichotomies as scientifically inadequate and an impediment to our ability to integrate the diverse information about psychiatric illness our research has produced. Empirically based pluralism provides a rigorous but dappled view of the etiology of psychiatric illness. Critically, it is based not on how we wish the world to be but how the difference-makers for psychiatric illness are in fact distributed.

    Exact cause and manner of death determination improves legislative safety for the individual and for society and guides aspects of national public health. In the International Classification of Diseases, codes R00-R99 are used for "symptoms, signs and abnormal clinical and laboratory findings......, not elsewhere classified" designated as "ill-defined" or "with unknown etiology". The World Health Organisation recommends avoiding the use of ill-defined and unknown causes of death in the death certificate as this terminology does not give any information concerning the possible conditions that led...... autopsy. Our study suggests that if all deaths in all age groups with unclear cause of death were systematically investigated with a forensic autopsy, only 2-3/1000 deaths per year would be coded as an ill-defined and unknown cause of death in national mortality statistics.

  13. Concepts of Illness Among the Swahili of Lamu, Kenya.

    Science.gov (United States)

    Gearhart, Rebecca; Abdulrehman, Munib Said

    2014-07-01

    The Swahili of Lamu, Kenya, understand illness as the result of a spiritual imbalance caused by personal transgression or an attack by harmful forces directed by an envious person. Another underlying component of the Swahili concept of illness is that each person's physical body operates in conjunction with personal attributes that are fixed at birth and determine moral character, behavior, and predisposition to ailments. When physical symptoms occur, the Swahili focus on identifying the human or supernatural entity that caused the illness in consultation with a range of healers who specialize in a variety of curing strategies. Two case studies illustrate how culturally congruent nursing care can be achieved when health care providers understand the Swahili framework of diagnosing and treating illness. © The Author(s) 2013.

    Early hospital readmissions within 30 days of discharge are common and costly. This research describes predictors of all-cause, 30-day hospital readmissions among persons with intellectual and developmental disabilities (IDD), a group known to experience high rates of hospitalization. A cohort of 66,484 adults with IDD from Ontario, Canada, was used to create two subgroups: individuals with IDD only and those with IDD and mental illness. The rates of hospital readmission were determined and contrasted with a comparison subgroup of people without IDD who have mental illness. Compared with those with mental illness only, individuals with IDD and mental illness were 1.7 times more likely to experience a hospital readmission within 30 days. Predictors of their readmission rates included being a young adult and having high morbidity levels. The high rate of hospital readmission suggests that individuals with IDD and mental illness need attention regarding discharge planning and outpatient follow-up.

  15. Mental illness: psychiatry's phlogiston.

    Science.gov (United States)

    Szasz, T

    2001-10-01

    In physics, we use the same laws to explain why airplanes fly, and why they crash. In psychiatry, we use one set of laws to explain sane behaviour, which we attribute to reasons (choices), and another set of laws to explain insane behaviour, which we attribute to causes (diseases). God, man's idea of moral perfection, judges human deeds without distinguishing between sane persons responsible for their behaviour and insane persons deserving to be excused for their evil deeds. It is hubris to pretend that the insanity defence is compassionate, just, or scientific. Mental illness is to psychiatry as phlogiston was to chemistry. Establishing chemistry as a science of the nature of matter required the recognition of the non-existence of phlogiston. Establishing psychiatry as a science of the nature of human behaviour requires the recognition of the non-existence of mental illness.

  16. Dogs as a diagnostic tool for ill health in humans.

    Science.gov (United States)

    Wells, Deborah L

    2012-01-01

    Researchers have long reported that dogs and cats improve the physical and psychological health of their human caregivers, and while it is still inconclusive, a substantial amount of research now lends support for the commonly held view that pets are good for us. Recently, studies have directed attention toward exploring the use of animals, most notably dogs, in the detection of disease and other types of health problems in people. This article reviews the evidence for dogs' ability to detect ill health in humans, focusing specifically on the detection of cancer, epileptic seizures, and hypoglycemia. The author describes the research carried out in this area and evaluates it in an effort to determine whether dogs have a role to play in modern health care as an alert tool or screening system for ill health. Where necessary, the author has highlighted weaknesses in the work and proposed directions for future studies.

  17. Estimating the true global burden of mental illness.

    Vigo, Daniel; Thornicroft, Graham; Atun, Rifat

    2016-02-01

    We argue that the global burden of mental illness is underestimated and examine the reasons for under-estimation to identify five main causes: overlap between psychiatric and neurological disorders; the grouping of suicide and self-harm as a separate category; conflation of all chronic pain syndromes with musculoskeletal disorders; exclusion of personality disorders from disease burden calculations; and inadequate consideration of the contribution of severe mental illness to mortality from associated causes. Using published data, we estimate the disease burden for mental illness to show that the global burden of mental illness accounts for 32·4% of years lived with disability (YLDs) and 13·0% of disability-adjusted life-years (DALYs), instead of the earlier estimates suggesting 21·2% of YLDs and 7·1% of DALYs. Currently used approaches underestimate the burden of mental illness by more than a third. Our estimates place mental illness a distant first in global burden of disease in terms of YLDs, and level with cardiovascular and circulatory diseases in terms of DALYs. The unacceptable apathy of governments and funders of global health must be overcome to mitigate the human, social, and economic costs of mental illness. Copyright © 2016 Elsevier Ltd.

    2013-12-01

    Literature about experiences of mental illness among ethnic minority has tended to focus on first-generation migrants. This study fills that gap by exploring experiences among highly acculturated Chinese-American patients with mental illness. Twenty-nine participants completed semi-structured interviews based on Kleinman's explanatory model, which were audio-taped, transcribed and coded for qualitative analysis. Beliefs about the causes of mental illness included biological factors, head trauma and personal losses. Issues relating to stigma and shame were also discussed. Highly acculturated ethnic minority patients may ascribe to a biomedical model at the same time as ascribing to culture-specific beliefs.

    Full Text Available Abstract Background In Great Britain (GB, data collected on pesticide associated illness focuses on acute episodes such as poisonings caused by misuse or abuse. This study aimed to investigate the extent and nature of pesticide-related illness presented and diagnosed in Primary Care and the feasibility of establishing a routine monitoring system. Methods A checklist, completed by General Practitioners (GP for all patients aged 18+ who attended surgery sessions, identified patients to be interviewed in detail on exposures and events that occurred in the week before their symptoms appeared. Results The study covered 59320 patients in 43 practices across GB and 1335 detailed interviews. The annual incidence of illness reported to GPs because of concern about pesticide exposure was estimated to be 0.04%, potentially 88400 consultations annually, approximately 1700 per week. The annual incidence of consultations where symptoms were diagnosed by GPs as likely to be related to pesticide exposure was 0.003%, an annual estimate of 6630 consultations i.e. about 128 per week. 41% of interviewees reported using at least one pesticide at home in the week before symptoms occurred. The risk of having symptoms possibly related to pesticide exposure compared to unlikely was associated with home use of pesticides after adjusting for age, gender and occupational pesticide exposure (OR = 1.88, 95% CI 1.51 – 2.35. Conclusion GP practices were diverse and well distributed throughout GB with similar symptom consulting patterns as in the Primary Care within the UK. Methods used in this study would not be feasible for a routine surveillance system for pesticide related illness. Incorporation of environmental health into Primary Care education and practice is needed.

    The mentally ill are vulnerable to human rights violations, particularly in Indonesia, where shackling is widespread. The aim of this study was to understand the provision of mental health care in Indonesia, thereby identifying ways to improve care and better support carers. Grounded theory methods were used. Study participants included health professionals, non-health professionals and individuals living with a mental disorder who were well at the time (n = 49). Data were collected through interviews conducted in 2011 and 2012. The core category of this grounded theory is 'connecting care' a term coined by the authors to describe a model of care that involves health professionals and non-health professionals, such as family members. Four main factors influence care-providers' decision-making: competence, willingness, available resources and compliance with institutional policy. Health professionals are influenced most strongly by institutional policy when deciding whether to accept or shift responsibility to provide care. Non-health professionals base their decisions largely on personal circumstances. Jointly-made decisions can be matched or unmatched. Unmatched decisions can result in forced provision of care, increasing risks of human rights violations. Generalization of this grounded theory is difficult as the research was conducted in two provinces of Indonesia. Institutional policy was important in the process of connecting care for the mentally ill in Indonesia and needs to be underpinned by legislation to protect human rights. Strengthening mental health legislation in Indonesia will allow nurses to connect care more effectively. © 2014 International Council of Nurses.

    Purpose Limited data are available on the survival of patients with breast cancer with preexisting mental illness, and elderly women are of special interest because they experience the highest incidence of breast cancer. Therefore, we compared all-cause and breast cancer-specific mortality for elderly patients with breast cancer with and without mental illness. Methods A retrospective cohort study was conducted by using SEER-Medicare data, including 19,028 women ≥ 68 years of age who were diagnosed with stage I to IIIa breast cancer in the United States from 2005 to 2007. Patients were classified as having severe mental illness if an International Classification of Diseases, Ninth Edition, Clinical Modification code for bipolar disorder, schizophrenia, or other psychotic disorder was recorded on at least one inpatient or two outpatient claims during the 3 years before breast cancer diagnosis. Patients were followed for up to 5 years after breast cancer diagnosis to assess survival outcomes, which were then compared with those of patients without mental illness. Results Nearly 3% of patients had preexisting severe mental illness. We observed a two-fold increase in the all-cause mortality hazard between patients with severe mental illness compared with those without mental illness after adjusting for age, income, race, ethnicity, geographic location, and marital status (adjusted hazard ratio, 2.19; 95% CI, 1.84 to 2.60). A 20% increase in breast cancer-specific mortality hazard was observed, but the association was not significant (adjusted hazard ratio, 1.20; 95% CI, 0.82 to 1.74). Patients with severe mental illness were more likely to be diagnosed with advanced breast cancer and aggressive tumor characteristics. They also had increased tobacco use and more comorbidities. Conclusion Patients with severe mental illness may need assistance with coordinating medical services.

  4. One health and cyanobacteria in freshwater systems: animal illnesses and deaths are sentinel events for human health risks.

    Harmful cyanobacterial blooms have adversely impacted human and animal health for thousands of years. Recently, the health impacts of harmful cyanobacteria blooms are becoming more frequently detected and reported. However, reports of human and animal illnesses or deaths associated with harmful cyanobacteria blooms tend to be investigated and reported separately. Consequently, professionals working in human or in animal health do not always communicate findings related to these events with one another. Using the One Health concept of integration and collaboration among health disciplines, we systematically review the existing literature to discover where harmful cyanobacteria-associated animal illnesses and deaths have served as sentinel events to warn of potential human health risks. We find that illnesses or deaths among livestock, dogs and fish are all potentially useful as sentinel events for the presence of harmful cyanobacteria that may impact human health. We also describe ways to enhance the value of reports of cyanobacteria-associated illnesses and deaths in animals to protect human health. Efficient monitoring of environmental and animal health in a One Health collaborative framework can provide vital warnings of cyanobacteria-associated human health risks.

    Full Text Available Chikungunya virus (CHIKV re-emerged in Sri Lanka in late 2006 after a 40-year hiatus. We sought to identify and characterize acute chikungunya infection (CHIK in patients presenting with acute undifferentiated febrile illness in unstudied rural and semi-urban southern Sri Lanka in 2007.We enrolled febrile patients ≥ 2 years of age, collected uniform epidemiologic and clinical data, and obtained serum samples for serology, virus isolation, and real-time reverse-transcriptase PCR (RT-PCR. Serology on paired acute and convalescent samples identified acute chikungunya infection in 3.5% (28/797 patients without acute dengue virus (DENV infection, 64.3% (18/28 of which were confirmed by viral isolation and/or real-time RT-PCR. No CHIKV/DENV co-infections were detected among 54 patients with confirmed acute DENV. Sequencing of the E1 coding region of six temporally distinct CHIKV isolates (April through October 2007 showed that all isolates posessed the E1-226A residue and were most closely related to Sri Lankan and Indian isolates from the same time period. Except for more frequent and persistent musculoskeletal symptoms, acute chikungunya infections mimicked DENV and other acute febrile illnesses. Only 12/797 (1.5% patients had serological evidence of past chikungunya infection.Our findings suggest CHIKV is a prominent cause of non-specific acute febrile illness in southern Sri Lanka.

    Fecal indicator bacteria used to assess illness risks in recreational waters (e.g., Escherichia coli, Enterococci) cannot discriminate among pollution sources. To address this limitation, human-associated Bacteroides markers have been proposed, but the risk of illness associated with the presence of these markers in recreational waters is unclear. Our objective was to estimate associations between human-associated Bacteroides markers in water and self-reported illness among swimmers at 6 U.S. beaches spanning 2003-2007. We used data from a prospectively-enrolled cohort of 12,060 swimmers surveyed about beach activities and water exposure on the day of their beach visit. Ten to twelve days later, participants reported gastroinestinal, diarrheal, and respiratory illnesses experienced since the visit. Daily water samples were analyzed for the presence of human-associated Bacteroides genetic markers: HF183, BsteriF1, BuniF2, HumM2. We used model-based standardization to estimate risk differences (RD) and 95% confidence intervals (CI). We assessed whether the presence of Bacteroides markers were modifiers of the association between general Enterococcus and illness among swimmers using interaction contrast. Overall we observed inconsistent associations between the presence of Bacteroides markers and illness. There was a pattern of increased risks of gastrointestinal (RD = 1.9%; 95% CI: 0.1%, 3.7%), diarrheal (RD = 1.3%; 95% CI: -0.2%, 2.7%), and respiratory illnesses (RD = 1.1%; 95% CI: -0.2%, 2.5%) associated with BsteriF1. There was no evidence that Bacteroides markers acted as modifiers of Enterococcus and illness. Patterns were similar when stratified by water matrix. Quantitative measures of fecal pollution using Bacteroides, rather than presence-absence indicators, may be necessary to accurately assess human risk specific to the presence of human fecal pollution.

    Clostridium perfringens type A is a common source of foodborne illness (FBI) in humans. Vegetative cells sporulate in the small intestinal tract and produce the major pathogenic factor C. perfringens enterotoxin. Although sporulation plays a critical role in the pathogenesis of FBI, the mechanisms inducing sporulation remain unclear. Bile salts were shown previously to induce sporulation, and we confirmed deoxycholate (DCA)-induced sporulation in C. perfringens strain NCTC8239 cocultured with human intestinal epithelial Caco-2 cells. In the present study, we performed transcriptome analyses of strain NCTC8239 in order to elucidate the mechanism underlying DCA-induced sporulation. Of the 2,761 genes analyzed, 333 were up- or downregulated during DCA-induced sporulation and included genes for cell division, nutrient metabolism, signal transduction, and defense mechanisms. In contrast, the virulence-associated transcriptional regulators (the VirR/VirS system, the agr system, codY, and abrB) were not activated by DCA. DCA markedly increased the expression of signaling molecules controlled by Spo0A, the master regulator of the sporulation process, whereas the expression of spo0A itself was not altered in the presence or absence of DCA. The phosphorylation of Spo0A was enhanced in the presence of DCA. Collectively, these results demonstrated that DCA induced sporulation, at least partially, by facilitating the phosphorylation of Spo0A and activating Spo0A-regulated genes in strain NCTC8239 while altering the expression of various genes. Disease caused by Clostridium perfringens type A consistently ranks among the most common bacterial foodborne illnesses in humans in developed countries. The sporulation of C. perfringens in the small intestinal tract is a key event for its pathogenesis, but the factors and underlying mechanisms by which C. perfringens sporulates in vivo currently remain unclear.

    Construction industry is an important sector that contributes to the development of economy and socioeconomy in Malaysia. It is a vital component in achieving the developed country status. However, fatalities in the Malaysian construction industry are a critical problem. Number of fatalities in this industry is the highest compared to other industries registered in Malaysia under the investigation of Department of Occupational Safety and Health (DOSH). Worksite element (worksite conditions, poor site management, construction tasks, and equipment & materials) was identified as one category of causes of occupational accidents and illnesses in Malaysian construction industry. The main objective of this study is to understand the perception of local construction personnel in terms of worksite element as causes of occupational accidents and illnesses in Malaysian residential construction industry. 13 housing projects that were registered with Ministry of Urban Wellbeing, Housing and Local Government and being permitted to perform construction work in 2012 were selected in Pulau Pinang to be studied using questionnaire survey. Worksite condition and poor site management was perceived as the most significant with the mean values of 3.68 and 3.61 respectively.

    Background: Globally women are one of the vulnerable populations and women without education and with mental illness are doubly disadvantaged. Aim: To find out the role of education in meeting the human rights needs of women with mental illness at family and community levels. Materials and Methods: A descriptive design was carried out among randomly selected recovered women (N = 100) with mental illness at a tertiary care center. Data was collected through face-to-face interview using a structured questionnaire. Results: Our findings revealed that human rights needs in physical needs dimension, i.e. access to safe drinking water (χ2 = 7.447, P illiteracy. The human rights needs in emotional dimension, i.e. afraid of family members (χ2 = 13.266, P < 0.004), not involved in making decisions regarding family matters (χ2 = 21.133, P < 0.00) and called with filthy nicknames (χ2 = 8.334, P < 0.040), were rated higher in literate women. The human rights needs in religious needs dimension, i.e. allowed to go to temple, church, mosque etc. (χ2 = 9.459, P < 0.024), were not satisfied by the illiterate women. Similarly, literate women felt that they were discriminated by community members due to their illness (χ2 = 9.823, P < 0.044). Conclusion: The findings of the present study suggested that women without education were more deprived of human rights needs than literate women. Thus, there is an urgent need to improve literacy of women and to strengthen the legal framework to protect the rights of the women with mental illness. PMID:26167021

    This article reviews an emergency department-based clinical vignette of a trafficked patient with co-occurring pregnancy-related, mental health, and substance use disorder issues. The authors, including a survivor of human trafficking, draw on their backgrounds in addiction care, human trafficking, emergency medicine, and psychiatry to review the literature on relevant general health and mental health consequences of trafficking and propose an approach to the clinical complexities this case presents. In their discussion, the authors explicate the deleterious role of implicit bias and diagnostic overshadowing in trafficked patients with co-occurring addiction and mental illness. Finally, the authors propose a trauma-informed, multidisciplinary response to potentially trafficked patients. © 2017 American Medical Association. All Rights Reserved.

    Full Text Available Human babesiosis caused by Babesia duncani is an emerging infectious disease in Canada. This malaria-like illness is brought about by a protozoan parasite infecting red blood cells. Currently, controversy surrounds which tick species are vectors of B. duncani. Since the availability of a serological or molecular test in Canada for B. duncani has been limited, we conducted a seven-year surveillance study (2011–2017 to ascertain the occurrence and geographic distribution of B. duncani infection country-wide. Surveillance case data for human B. duncani infections were collected by contacting physicians and naturopathic physicians in the United States and Canada who specialize in tick-borne diseases. During the seven-year period, 1119 cases were identified. The presence of B. duncani infections was widespread across Canada, with the highest occurrence in the Pacific coast region. Patients with human babesiosis may be asymptomatic, but as this parasitemia progresses, symptoms range from mild to fatal. Donors of blood, plasma, living tissues, and organs may unknowingly be infected with this piroplasm and are contributing to the spread of this zoonosis. Our data show that greater awareness of human babesiosis is needed in Canada, and the imminent threat to the security of the Canadian blood supply warrants further investigation. Based on our epidemiological findings, human babesiosis should be a nationally notifiable disease in Canada. Whenever a patient has a tick bite, health practitioners must watch for B. duncani infections, and include human babesiosis in their differential diagnosis.

    Vibrio parahaemolyticus (Vp) is a naturally occurring bacterium found in marine environments worldwide. It can cause gastrointestinal illness in humans, primarily through raw oyster consumption. Water temperatures, and potentially other environmental factors, play an important role in the growth and proliferation of Vp in the environment. Quantifying the relationships between environmental variables and indicators or incidence of Vp illness is valuable for public health surveillance to inform and enable suitable preventative measures. This study aimed to assess the relationship between environmental parameters and Vp in British Columbia (BC), Canada. The study used Vp counts in oyster meat from 2002-2015 and laboratory confirmed Vp illnesses from 2011-2015 for the province of BC. The data were matched to environmental parameters from publicly available sources, including remote sensing measurements of nighttime sea surface temperature (SST) obtained from satellite readings at a spatial resolution of 1 km. Using three separate models, this paper assessed the relationship between (1) daily SST and Vp counts in oyster meat, (2) weekly mean Vp counts in oysters and weekly Vp illnesses, and (3) weekly mean SST and weekly Vp illnesses. The effects of salinity and chlorophyll a were also evaluated. Linear regression was used to quantify the relationship between SST and Vp, and piecewise regression was used to identify SST thresholds of concern. A total of 2327 oyster samples and 293 laboratory confirmed illnesses were included. In model 1, both SST and salinity were significant predictors of log(Vp) counts in oyster meat. In model 2, the mean log(Vp) count in oyster meat was a significant predictor of Vp illnesses. In model 3, weekly mean SST was a significant predictor of weekly Vp illnesses. The piecewise regression models identified a SST threshold of approximately 14 o C for both model 1 and 3, indicating increased risk of Vp in oyster meat and Vp illnesses at higher

    In mammals, early adverse experiences, including mother-pup interactions, shape the response of an individual to chronic stress or to stress-related diseases during adult life. This has led to the elaboration of the theory of the developmental origins of health and disease, in particular adult diseases such as cardiovascular and metabolic disorders. In addition, in humans, as stated by Massimo Fagioli's Human Birth Theory, birth is healthy and equal for all individuals, so that mental illness develop exclusively in the postnatal period because of the quality of the relationship in the first year of life. Thus, this review focuses on the importance of programming during the early developmental period on the manifestation of adult diseases in both animal models and humans. Considering the obvious differences between animals and humans we cannot systematically move from animal models to humans. Consequently, in the first part of this review, we will discuss how animal models can be used to dissect the influence of adverse events occurring during the prenatal and postnatal periods on the developmental trajectories of the offspring, and in the second part, we will discuss the role of postnatal critical periods on the development of mental diseases in humans. Epigenetic mechanisms that cause reversible modifications in gene expression, driving the development of a pathological phenotype in response to a negative early postnatal environment, may lie at the core of this programming, thereby providing potential new therapeutic targets. The concept of the Human Birth Theory leads to a comprehension of the mental illness as a pathology of the human relationship immediately after birth and during the first year of life.

    2015-01-01

    Full Text Available Background: Globally women are one of the vulnerable populations and women without education and with mental illness are doubly disadvantaged. Aim: To find out the role of education in meeting the human rights needs of women with mental illness at family and community levels. Materials and Methods: A descriptive design was carried out among randomly selected recovered women (N = 100 with mental illness at a tertiary care center. Data was collected through face-to-face interview using a structured questionnaire. Results: Our findings revealed that human rights needs in physical needs dimension, i.e. access to safe drinking water (c2 = 7.447, P < 0.059 and serving in the same utensils (c2 = 10.866, P < 0.012, were rated higher in women with illiteracy. The human rights needs in emotional dimension, i.e. afraid of family members (c2 = 13.266, P < 0.004, not involved in making decisions regarding family matters (c2 = 21.133, P < 0.00 and called with filthy nicknames (c2 = 8.334, P < 0.040, were rated higher in literate women. The human rights needs in religious needs dimension, i.e. allowed to go to temple, church, mosque etc. (c2 = 9.459, P < 0.024, were not satisfied by the illiterate women. Similarly, literate women felt that they were discriminated by community members due to their illness (c2 = 9.823, P < 0.044. Conclusion: The findings of the present study suggested that women without education were more deprived of human rights needs than literate women. Thus, there is an urgent need to improve literacy of women and to strengthen the legal framework to protect the rights of the women with mental illness.

    Full Text Available Abstract Background People hold a wide variety of beliefs concerning the causes of illness. Such beliefs vary across cultures and, among immigrants, may be influenced by many factors, including level of acculturation, gender, level of education, and experience of illness and treatment. This study examines illness causal beliefs in Turkish-immigrants in Australia. Methods Causal beliefs about somatic and mental illness were examined in a sample of 444 members of the Turkish population of Melbourne. The socio-demographic characteristics of the sample were broadly similar to those of the Melbourne Turkish community. Five issues were examined: the structure of causal beliefs; the relative frequency of natural, supernatural and metaphysical beliefs; ascription of somatic, mental, or both somatic and mental conditions to the various causes; the correlations of belief types with socio-demographic, modernizing and acculturation variables; and the relationship between causal beliefs and current illness. Results Principal components analysis revealed two broad factors, accounting for 58 percent of the variation in scores on illness belief scales, distinctly interpretable as natural and supernatural beliefs. Second, beliefs in natural causes were more frequent than beliefs in supernatural causes. Third, some causal beliefs were commonly linked to both somatic and mental conditions while others were regarded as more specific to either somatic or mental disorders. Last, there was a range of correlations between endorsement of belief types and factors defining heterogeneity within the community, including with demographic factors, indicators of modernizing and acculturative processes, and the current presence of illness. Conclusion Results supported the classification of causal beliefs proposed by Murdock, Wilson & Frederick, with a division into natural and supernatural causes. While belief in natural causes is more common, belief in supernatural causes

    Aim: To describe chest radiographic abnormalities and assess their usefulness for predicting causes of fever in a resource-limited setting. Materials and methods: Febrile patients were enrolled in Moshi, Tanzania, and chest radiographs were evaluated by radiologists in Tanzania and the United States. Radiologists were blinded to the results of extensive laboratory evaluations to determine the cause of fever. Results: Of 870 febrile patients, 515 (59.2%) had a chest radiograph available; including 268 (66.5%) of the adolescents and adults, the remainder were infants and children. One hundred and nineteen (44.4%) adults and 51 (20.6%) children were human immunodeficiency virus (HIV)-infected. Among adults, radiographic abnormalities were present in 139 (51.9%), including 77 (28.7%) with homogeneous and heterogeneous lung opacities, 26 (9.7%) with lung nodules, 25 (9.3%) with pleural effusion, 23 (8.6%) with cardiomegaly, and 13 (4.9%) with lymphadenopathy. Among children, radiographic abnormalities were present in 87 (35.2%), including 76 (30.8%) with homogeneous and heterogeneous lung opacities and six (2.4%) with lymphadenopathy. Among adolescents and adults, the presence of opacities was predictive of Streptococcus pneumoniae and Coxiella burnetii, whereas the presence of pulmonary nodules was predictive of Histoplasma capsulatum and Cryptococcus neoformans. Conclusions: Chest radiograph abnormalities among febrile inpatients are common in northern Tanzania. Chest radiography is a useful adjunct for establishing an aetiologic diagnosis of febrile illness and may provide useful information for patient management, in particular for pneumococcal disease, Q fever, and fungal infections

    2007-01-01

    This article is part of a working project which assesses Ontario's mental health legislation and practice vis-à-vis international human rights standards. The paper focuses on procedural safeguards provided by the major international human rights instruments in the field of mental health law such as the UN Principles for the Protection of Persons with Mental Illness (MI Principles) and the European Convention on Human Rights as interpreted by the European Human Rights Court. In analysing Ontario's compliance with international standards, the paper will explore some problems arising from the implementation of the legislation with which the author is familiar with from his experience as counsel for the Consent and Capacity Board. The paper aims to generate discussion for potential reforms in domestic legal systems and to provide a methodology to be used as a tool to assess similar mental health legislation in other local contexts.

    Full Text Available The Centers for Disease Control currently report cervical, vulvar, vaginal, anal and some head and neck cancers as human papillomavirus (HPV-associated cancers. Only cervical cancer is listed amongst acquired immunodeficiency syndrome (AIDS defining illnesses. All of these cancers may represent progression of the immunocompromised state with the inability to eradicate viral infection. This study reports the case of a 27-year old HIV positive female presenting with a persistent right vulvar exophytic lesion. High-risk HPV analysis and immunostaining for P16 were both positive. A biopsy of the lesion revealed invasive squamous cell carcinoma. The patient underwent neoadjuvant radiation and chemotherapy followed by a radical vulvectomy. During treatment, her CD4 T-lymphocyte count decreased to 120 advancing her condition from HIV to AIDS. This case suggests that all HPV-associated cancers should be included as AIDS defining illnesses.

    Nearly 13% of the U.S. population is comprised of foreign-born individuals, with Somalis constituting one of the largest resettled groups. Research suggests that, among Somali refugees, rates of mental illness are high. Yet research shows Somalis underutilize mental health services. Understanding their perceptions of mental illness and its cures may help practitioners to design more effective treatments for this population. Thus, this pilot study investigated Somali refugees' perceptions of mental illness and its treatments. Using purposive sampling, this qualitative study interviewed 20 Somali refugees using a semi-structured interview guide. Qualitative analysis yielded participants' perceptions of mental illness through their descriptions of physical symptoms accompanying mental illness, the stigma of mental illness, causes of mental illness, medical and non-medical treatments for mental illness, spirit possession causing mental illness, and the Qur'an as treatment for mental illness. Such information may help practitioners in the United States approach Somali clients in the most culturally coherent manner.

    Accident prevention techniques and technologies have evolved significantly throughout this century from the earliest establishment of standards and procedures to the safety engineering improvements the fruits of which we enjoy today. Most of the recent prevention efforts focused on humans and defining human factor causes of accidents. This paper builds upon the remarkable successes of the past by looking beyond the human's action in accident causation to the organizational factors that put the human in the position to cause the accident. This organizational approach crosses all functions and all career fields

  9. The Role of Human Milk Immunomodulators in Protecting Against Viral Bronchiolitis and Development of Chronic Wheezing Illness.

    2015-07-07

    Infants who are breastfed are at an immunological advantage when compared with formula fed infants, evidenced by decreased incidence of infections and diminished propensity for long term conditions, including chronic wheeze and/or asthma. Exclusive breastfeeding reduces the duration of hospital admission, risk of respiratory failure and requirement for supplemental oxygen in infants hospitalised with bronchiolitis suggesting a potentially protective mechanism. This review examines the evidence and potential pathways for protection by immunomodulatory factors in human milk against the most common viral cause of bronchiolitis, respiratory syncytial virus (RSV), and subsequent recurrent wheeze in infants. Further investigations into the interplay between respiratory virus infections such as RSV and how they affect, and are affected by, human milk immunomodulators is necessary if we are to gain a true understanding of how breastfeeding protects many infants but not all against infections, and how this relates to long-term protection against conditions such as chronic wheezing illness or asthma.

    Full Text Available Background: Despite the rights of persons with mental illnesses (PwMI are protected by law in India, human rights of PwMI is being violated in many ways. There is dearth of literature on the human rights of PwMI in India. Materials and Methods: This cross-sectional study was conducted to understand the perceived human rights temperature of community in PwMI. Data were collected from PwMI (diagnosed with schizophrenia, bipolar disorder and schizoaffective disorder, and symptomatically stable for 3 years seeking outpatient psychiatric treatment from private psychiatric hospitals and clinics in Kozhikode (Calicut district of Kerala state, India. Data were collected using “Taking the Human Rights Temperature of Your Community” which was modified and validated in Indian population and a sociodemographic schedule which was prepared by the researchers. Results: The majority were males (54.2%. Mean duration of illness as 10.42 ± 6.43 years. Mean score of the human rights temperature was 68.31 ± 5.95. Perceived major concerns in the areas of career opportunity (59.5%, discrimination in hiring for work (61.3%, help and care in development of PwMI (64.5%, equal opportunity to avail treatment and cost incurred in it (60.5%, involvement in decision making (46.7%, and responsiveness of the community when any rights violation happens (44.9%. Conclusion: Human rights of PwMI are a major concern. Functioning of the mental health authority and legal aid clinics has to be strengthened to address rights issues of PwMI.

    2018-06-01

    Viewing mental illness as an 'illness like any other' and promoting biogenetic causes have been explored as a stigma-reduction strategy. The relationship between causal beliefs and mental illness stigma has been researched extensively in the general public, but has gained less attention in more clinically-relevant populations (i.e. people with mental illness and mental health professionals). A systematic review examining whether endorsing biogenetic causes decreases mental illness stigma in people with mental illness and mental health professionals was undertaken using the preferred reporting items for systematic reviews and meta-analyses guidelines. Multiple databases were searched, and studies that explored the relationship between biogenetic causal beliefs and mental illness stigma in people with mental illness or mental health professionals were considered. Studies were included if they focussed on depression, schizophrenia, or mental illness in general, were in English, and had adult participants. The search identified 11 journal articles reporting on 15 studies, which were included in this review. Of these, only two provided evidence that endorsing biogenetic causes was associated with less mental illness stigma in people with mental illness or mental health professionals. The majority of studies in the present review (n = 10) found that biogenetic causal beliefs were associated with increased stigma or negative attitudes towards mental illness. The present review highlights the lack of research exploring the impacts of endorsing biogenetic causes in people with mental illness and mental health professionals. Clinical implications associated with these results are discussed, and suggestions are made for further research that examines the relationship between causal beliefs and treatment variables. © 2017 Australian College of Mental Health Nurses Inc.

    Many studies have reported that the prevalence of mental illness and cognitive disability is higher among homeless individuals compared to the general population, and the rates of mental illness among the homeless population have recently increased. This study: (i) compares causes of homelessness or barriers to escaping homelessness for people with/without mental illness/cognitive disability; (ii) reveals problems with the Japanese homeless policy; and (iii) proposes an effective and necessary support system. The participants were 114 homeless individuals. A psychiatric diagnostic interview and the Wechsler Adult Intelligence Scale, version III were used to measure participants' mental health and cognitive abilities. A questionnaire was administered comprising 17 items related to the causes of their homelessness and barriers to escaping from it. Participants were divided into four groups - with/without mental illness or cognitive disability - and Fisher's exact test was used to compare the questionnaire results. Individuals with cognitive disabilities considered bad relationships with their family members to be the cause of their homelessness. Conversely, normal individuals considered their homelessness to be the result of debt more so than did individuals with mental problems. Individuals with mental illness had more difficulties escaping homelessness than did either normal individuals or individuals with cognitive disability. This tendency was observed most strongly among individuals with both mental illness and cognitive disability. Most homeless individuals considered economic problems to be the cause of their homelessness; however, difficulties with human relationships were also important factors and were more difficult for participants to acknowledge. Furthermore, these difficulties were exacerbated among those individuals with mental problems. © 2016 The Authors.

  15. Statistical aspects and risks of human-caused earthquakes

    Klose, C. D.

    2013-12-01

    The seismological community invests ample human capital and financial resources to research and predict risks associated with earthquakes. Industries such as the insurance and re-insurance sector are equally interested in using probabilistic risk models developed by the scientific community to transfer risks. These models are used to predict expected losses due to naturally occurring earthquakes. But what about the risks associated with human-caused earthquakes? Such risk models are largely absent from both industry and academic discourse. In countries around the world, informed citizens are becoming increasingly aware and concerned that this economic bias is not sustainable for long-term economic growth, environmental and human security. Ultimately, citizens look to their government officials to hold industry accountable. In the Netherlands, for example, the hydrocarbon industry is held accountable for causing earthquakes near Groningen. In Switzerland, geothermal power plants were shut down or suspended because they caused earthquakes in canton Basel and St. Gallen. The public and the private non-extractive industry needs access to information about earthquake risks in connection with sub/urban geoengineeing activities, including natural gas production through fracking, geothermal energy production, carbon sequestration, mining and water irrigation. This presentation illuminates statistical aspects of human-caused earthquakes with respect to different geologic environments. Statistical findings are based on the first catalog of human-caused earthquakes (in Klose 2013). Findings are discussed which include the odds to die during a medium-size earthquake that is set off by geomechanical pollution. Any kind of geoengineering activity causes this type of pollution and increases the likelihood of triggering nearby faults to rupture.

  16. Manual materials handling: the cause of over-exertion injury and illness in industry.

    Chaffin, D B

    1979-01-01

    It is reported from various sources that overexertion due to lifting, pushing, pulling, and carrying objects accounts for about 27 percent of all compensable industrial injury and illness in the United States. Resulting strain/sprain injuries account for over 50 percent of workmen's compensation clams in many industries. Almont two-thirds of these involve back pain, with reported compensation and medical payments totaling well over one billion dollars annually in the U.S. An estimated 300,000 plus workers will be affected each year, 5 to 10 percent of whom will have a permanent disability and often will be unemployable. This paper attempts to describe four basic approaches used to study this occupational health problem. In so doing, a concerted effort is made to identifiy the gaps in knowledge which need to be more fully researched. The approaches utilized to understand and control the hazards of manual materials handling are: 1) epidemiological studies of job and worker attributes to identify those that individually and in combination cause musculoskeletal incidents, 2) psychophysical studies to ascertain the volitional tolerance of workers to the stress mitigated by manual materials-handling activities, 3) biomechanical studies of the musculoskeletal system during common exertions required in manual materials-handling activities, and 4) physiological studies of the strain imposed on the cardiovascular system during repeated load-handling activities. The state of knowledge from each of these approaches is summarized briefly, and a case is made that much research is still needed to substantiate the necessary controls to lessen the economic burden and human suffering associated with manual materials-handling acts in industry.

    2010-09-01

    This paper reports two studies that investigated children's conceptions of mental illness using a naïve theory approach, drawing upon a conceptual framework for analysing illness representations which distinguishes between the identity, causes, consequences, curability, and timeline of an illness. The studies utilized semi-structured interviewing and card selection tasks to assess 6- to 11-year-old children's conceptions of the causes and consequences (Study 1) and the curability and timeline (Study 2) of different mental and physical illnesses/ailments. The studies revealed that, at all ages, the children held coherent causal-explanatory ideas about the causes, consequences, curability, and timeline of both mental and physical illnesses/ailments. However, while younger children tended to rely on their knowledge of common physical illnesses when thinking about mental illnesses, providing contagion and contamination explanations of cause, older children demonstrated differences in their thinking about mental and physical illnesses. No substantial gender differences were found in the children's thinking. It is argued that children hold coherent conceptions of mental illness at all ages, but that mental illness only emerges as an ontologically distinct conceptual domain by the end of middle childhood.

    This study aimed to investigate children's thinking about mental illness by employing a well-established framework of adult illness understanding. The study adopted a semistructured interview technique and a card selection task to assess children's responses to causes, consequences, timeline and curability of the different types of mental illness. The children were aged between 5 and 11 years. Results indicated a developmental trend in the children's thinking about mental illness; there was an increase in the children's understanding of the causes, consequences, curability and timeline of mental illness with age. The older children demonstrated a more sophisticated and accurate thinking about mental illness compared with the younger children, who tended to rely on a medical model in order to comprehend novel mental illnesses. Furthermore, the girls exhibited more compassion, showing greater social acceptance compared with the boys. The Leventhal model provides a useful framework within which to investigate children's knowledge and understanding of mental illness. Limitations of the study and implications for future research are discussed.

    Pathogenic Leptospira transmits from animals to humans, causing the zoonotic life-threatening infection called leptospirosis. This infection is reported worldwide with higher risk in tropical regions. Symptoms of leptospirosis range from mild illness to severe illness such as liver damage, kidney failure, respiratory distress, meningitis, and fatal hemorrhagic disease. Invasive species of Leptospira rapidly disseminate to multiple tissues where this bacterium damages host endothelial cells, increasing vascular permeability. Despite the burden in humans and animals, the pathogenic mechanisms of Leptospira infection remain to be elucidated. The pathogenic leptospires adhere to endothelial cells and permeabilize endothelial barriers in vivo and in vitro. In this study, human endothelial cells were infected with the pathogenic L. interrogans serovar Copenhageni or the saprophyte L. biflexa serovar Patoc to investigate morphological changes and other distinctive phenotypes of host cell proteins by fluorescence microscopy. Among those analyzed, 17 proteins from five biological classes demonstrated distinctive phenotypes in morphology and/or signal intensity upon infection with Leptospira. The affected biological groups include: 1) extracellular matrix, 2) intercellular adhesion molecules and cell surface receptors, 3) intracellular proteins, 4) cell-cell junction proteins, and 5) a cytoskeletal protein. Infection with the pathogenic strain most profoundly disturbed the biological structures of adherens junctions (VE-cadherin and catenins) and actin filaments. Our data illuminate morphological disruptions and reduced signals of cell-cell junction proteins and filamentous actin in L. interrogans-infected endothelial cells. In addition, Leptospira infection, regardless of pathogenic status, influenced other host proteins belonging to multiple biological classes. Our data suggest that this zoonotic agent may damage endothelial cells via multiple cascades or pathways

    Blood transfusions and blood products are often given as a life-saving measure in patients with critical illness. However, some patients, such as Jehovah's Witnesses, may refuse their administration due to religious beliefs. Jehovah's Witnesses accept most available medical treatments, but not blood transfusions or blood products due to their religion's interpretation of several passages from the Bible. Since recombinant human erythropoietin (rHuEPO) became available, several cases have been reported in which rHuEPO was successfully administered to critically ill Jehovah's Witnesses. Administration of rHuEPO in combination with other blood conservation techniques has been shown to increase hemoglobin levels and survival in patients who experienced trauma, burns, general surgery, or gastrointestinal hemorrhage. We performed a literature search of the MEDLINE and International Pharmaceutical Abstracts databases of rHuEPO therapy in the Jehovah's Witness population. Fourteen cases were identified in which rHuEPO was administered to Jehovah's Witnesses who required the drug for critical care resuscitation as an alternative to blood products. In each clinical situation, rHuEPO enhanced erythropoiesis; however, time to the start of treatment, dosages, route of administration, and treatment duration varied widely. Supplementation with adjunctive agents, such as iron, folic acid, and vitamin B12, was also beneficial. Use of rHuEPO in Jehovah's Witnesses may provide an alternative to blood transfusions or blood products. Other alternatives, such as hemoglobin-based oxygen carriers and perfluorocarbons, are also being explored.

    Full Text Available Background: Domestic violence against women is the most pervasive human rights violation in the world today. According to UNiTE to End Violence against Women (2009 by UN Women, In the United States, one-third of women murdered each year are killed by intimate partners. In South Africa, a woman is killed every 6 hours by an intimate partner. The Objective: To assess the magnitude and causes of domestic violence with mental illness & normal women. Material & Methods: The sample of study comprised of 50 women with mental illness and 50 normal women. Mental illness patients diagnosed according to with Axis one psychiatric Disorder DSM IV-TR, who were selected from the Psychiatry OPD and ward of the S.S. Hospital, BHU and normal women were be selected from the accompany with patients of Sir Sunder Lal Hospital. The patients were assessed on the structured questionnaire on Domestic Violence. Results – The domestic violence present in married women with mental illness was 72% and normal women were 36%. Perceived causes of domestic violence in married women with mental illness were more compared to those with normal women. The health care personnel should be given an opportunity to update their knowledge regarding domestic violence and there is need education for domestic violence and cessation, so that they can help the women to protect/prevent domestic violence.

  4. Physics of Fission and Fusion for the Diagnostics and Monitoring of the Deadliest Illness of Mankind

    2015-03-01

    The physics of fission and fusion has been well known for the past several decades. It has been used primarily for destructive purposes (e. g., nuclear armaments) with both processes. However for peaceful purposes, e. g., generation of energy, only fission has been used, but not yet fusion. It is also well known that the deadliest illness of mankind is the group of illnesses called mental illnesses. A large segment of the world population is afflicted by them causing more loss of human lives, destruction of families, businesses and overall economy than all the other illnesses combined. Despite outstanding advancements in medical research and huge investments, unfortunately no diagnostic techniques have yet been found which can characterize the patient's mental illness. Consequently, no quantitative monitoring techniques are available to evaluate the efficacy of the various medicines used to treat the patients, and to develop them in the pharmaceutical labs. The purpose of this paper is to apply the constructive aspects of fission and fusion to identify the missing links in the diagnosis and treatment of mental illnesses. Each patient is a unique human being, not a disease or a group of symptoms. This makes it even more difficult to treat the patients suffering from mental illnes

    Socioeconomic status has important associations with disease-specific mortality in the general population. Although individuals with Severe Mental Illnesses (SMI) experience significant premature mortality, the relationship between socioeconomic status and mortality in this group remains under investigated. We aimed to assess the impact of socioeconomic status on rate and cause of death in individuals with SMI (schizophrenia and bipolar disorder) relative to the local (Glasgow) and wider (Scottish) populations. Cause and age of death during 2006-2010 inclusive for individuals with schizophrenia or bipolar disorder registered on the Glasgow Psychosis Clinical Information System (PsyCIS) were obtained by linkage to the Scottish General Register Office (GRO). Rate and cause of death by socioeconomic status, measured by Scottish Index of Multiple Deprivation (SIMD), were compared to the Glasgow and Scottish populations. Death rates were higher in people with SMI across all socioeconomic quintiles compared to the Glasgow and Scottish populations, and persisted when suicide was excluded. Differences were largest in the most deprived quintile (794.6 per 10,000 population vs. 274.7 and 252.4 for Glasgow and Scotland respectively). Cause of death varied by socioeconomic status. For those living in the most deprived quintile, higher drug-related deaths occurred in those with SMI compared to local Glasgow and wider Scottish population rates (12.3% vs. 5.9%, p = socioeconomic quintiles compared to the Glasgow and Scottish populations but was most marked in the most deprived quintiles when suicide was excluded as a cause of death. Further work assessing the impact of socioeconomic status on specific causes of premature mortality in SMI is needed.

    In sub-Saharan Africa, the use of malaria rapid diagnostic tests (mRDT) has raised awareness of alternative fever causes in children but few studies have included adults. To address this gap, we conducted a study of mRDT-negative fever aetiologies among children and adults in Tanzania. A total of 1028 patients aged 3 months to 50 years with a febrile illness and negative mRDT were enrolled from a Tanzanian hospital outpatient department. All had a physical examination and cultures from blood, nasopharynx/throat and urine. Patients were followed on Days 7 and 14 and children meeting WHO criteria for pneumonia were followed on Day 2 with chest radiology. Respiratory symptoms were the most frequent presenting complaint, reported by 20.3% of adults and 64.0% (339/530) of children. Of 38 X-rayed children meeting WHO pneumonia criteria, 47.4% had a normal X-ray. Overall, only 1.3% of 1028 blood cultures were positive. Salmonella typhi was the most prevalent pathogen isolated (7/13, 53.8%) and S. typhi patients reported fever for a median of 7 days (range 2-14). Children with bacteraemia did not present with WHO symptoms requiring antibiotic treatment. Young children and adults had similar prevalences of positive urine cultures (24/428 and 29/498, respectively). Few outpatient fevers are caused by blood stream bacterial infection, and most adult bacteraemia would be identified by current clinical guidelines although paediatric bacteraemia may be more difficult to diagnose. While pneumonia may be overdiagnosed, urinary tract infection was relatively common. Our results emphasise the difficulty in identifying African children in need of antibiotics among the majority who do not. © 2015 The Authors.

    Background. Describing the frequency, severity, and causes of sports injuries and illnesses reliably is important for quantifying the risk to athletes and providing direction for prevention initiatives. Methods. Time-loss and/or medical-attention definitions have long been used in sports injury/illness epidemiology research, but the limitations to these definitions mean that some events are incorrectly classified or omitted completely, where athletes continue to train and compete at high levels but experience restrictions in their performance. Introducing a graded definition of performance-restriction may provide a solution to this issue. Results. Results from the Great Britain injury/illness performance project (IIPP) are presented using a performance-restriction adaptation of the accepted surveillance consensus methodologies. The IIPP involved 322 Olympic athletes (males: 172; female: 150) from 10 Great Britain Olympic sports between September 2009 and August 2012. Of all injuries (n = 565), 216 were classified as causing time-loss, 346 as causing performance-restriction, and 3 were unclassified. For athlete illnesses (n = 378), the majority (P < 0.01) resulted in time-loss (270) compared with performance-restriction (101) (7 unclassified). Conclusions. Successful implementation of prevention strategies relies on the correct characterisation of injury/illness risk factors. Including a performance-restriction classification could provide a deeper understanding of injuries/illnesses and better informed prevention initiatives. PMID:26464883

    The Global Movement for Mental Health has brought renewed attention to the neglect of people with mental illness within health policy worldwide. The maltreatment of the mentally ill in many low-income countries is widely reported within psychiatric hospitals, informal healing centres, and family homes. International agencies have called for the development of legislation and policy to address these abuses. However such initiatives exemplify a top-down approach to promoting human rights which historically has had limited impact at the level of those living with mental illness and their families. This research forms part of a longitudinal anthropological study of people with severe mental illness in rural Ghana. Visits were made to over 40 households with a family member with mental illness, as well as churches, shrines, hospitals and clinics. Ethnographic methods included observation, conversation, semi-structured interviews and focus group discussions with people with mental illness, carers, healers, health workers and community members. Chaining and beating of the mentally ill was found to be commonplace in homes and treatment centres in the communities studied, as well as with-holding of food ('fasting'). However responses to mental illness were embedded within spiritual and moral perspectives and such treatment provoked little sanction at the local level. Families struggled to provide care for severely mentally ill relatives with very little support from formal health services. Psychiatric services were difficult to access, particularly in rural communities, and also seen to have limitations in their effectiveness. Traditional and faith healers remained highly popular despite the routine maltreatment of the mentally ill in their facilities. Efforts to promote the human rights of those with mental illness must engage with the experiences of mental illness within communities affected in order to grasp how these may underpin the use of practices such as mechanical

    Alaska's 1049-mile Iditarod Trail Sled Dog Race is the world's longest sled dog race and the flagship event in the sport of sled dog racing. Race conditions are typically harsh. Physicians are not officially enlisted to care for human competitors. Instead, medical needs are met through an informal system of volunteers, local health care providers, and a fleet of bush planes. The goals of this study were to identify the types of human injury and illness experienced and the methods by which these conditions are treated. Competitors in the 2010 Iditarod were surveyed at the halfway point and at the finish of the race. Survey elements included specific types and frequencies of injuries and illnesses, and the sources and types of treatments. Seventy-one teams entered the race, 62 participated in the halfway point survey, and 55 completed the finish line survey. Ninety-nine injuries were reported by 42 (68%) of the survey respondents. Frostbite was the most common injury, occurring in 20 (31%) of the respondents. Musculoskeletal pain was also commonly reported. Two mushers sustained closed head injuries, with 1 requiring evacuation. Twenty-three mushers (37%) reported an acute nontraumatic condition, most frequently an upper respiratory infection (9 respondents). In most instances, medical conditions were self-managed. Race veterinarians and support staff, as well as local village clinicians, administered the majority of care, typically wound care or oral antibiotic administration. Most injuries and illnesses sustained by mushers in the Iditarod are minor and self-treatable. Life-threatening conditions are rare, and the need for an organized medical care system seems low.

  15. Airborne pathogens from dairy manure aerial irrigation and the human health risk

    Science.gov (United States)

    Borchardt, Mark A.; Burch, Tucker R

    2016-01-01

    Dairy manure, like the fecal excrement from any domesticated or wild animal, can contain pathogens capable of infecting humans and causing illness or even death. Pathogens in dairy manure can be broadly divided into categories of taxonomy or infectiousness. Dividing by taxonomy there are three pathogen groups in dairy manure: viruses (e.g., bovine rotavirus), bacteria (e.g., Salmonella species), and protozoa (e.g., Cryptosporidium parvum). There are two categories of infectiousness for pathogens found in animals: those that are zoonotic and those that are not. A zoonotic pathogen is one that can infect both human and animal hosts. Some zoonotic pathogens found in dairy manure cause illness in both hosts (e.g., Salmonella) while other zoonotic pathogens, like Escherichia coli O157:H7, (enterohemorrhagic E. coli (EHEC)) cause illness only in humans. As a general rule, the gastrointestinal viruses found in dairy manure are not zoonotic. While there are exceptions (e.g., rare reports of bovine rotavirus infecting children), for the most part the viruses in dairy manure are not a human health concern. The primary concerns are the zoonotic bacteria and protozoa in dairy manure.

  19. Ethics and mental illness research.

    Roberts, Laura Weiss

    2002-09-01

    ethical issues are recognized as inextricably linked: science as a human activity carries complex ethical meanings and responsibilities, and ethics itself is subject to scrutiny and amenable to scientific inquiry. Building a broader, more versatile, and more effective repertoire of safeguards will be increasingly important, and safeguards, in this view, represent a modest price for the privilege of studying serious illnesses--diseases that cause grave suffering and yet are a source of both vulnerability and strength. In this paradigm, attention to ethics safeguards is no longer understood as a barrier to scientific advancement, but rather as the means by which psychiatric research may be conducted with broad societal support, honorably and, ultimately, with the expectation of bringing benefit to millions of people with mental illness.

    This article proposes a focused, novel sub-set of the cognitive behavioral therapy approach to hypnotherapy for physically ill patients, based upon the illness/non-illness psychotherapeutic model for physically ill patients. The model is based on three logical rules used in differentiating illness from non-illness: duality, contradiction, and complementarity. The article discusses the use of hypnotic interventions to help physically ill and/or disabled patients distinguish between illness and non-illness in their psychotherapeutic themes and attitudes. Two case studies illustrate that patients in this special population group can be taught to learn the language of change and to use this language to overcome difficult situations. The model suggests a new clinical mode of treatment in which individuals who are physically ill and/or disabled are helped in coping with actual motifs and thoughts related to non-illness or non-disability.

    The Indo-Pacific warm pool (IPWP) has warmed and grown substantially during the past century. The IPWP is Earth's largest region of warm sea surface temperatures (SSTs), has the highest rainfall, and is fundamental to global atmospheric circulation and hydrological cycle. The region has also experienced the world's highest rates of sea-level rise in recent decades, indicating large increases in ocean heat content and leading to substantial impacts on small island states in the region. Previous studies have considered mechanisms for the basin-scale ocean warming, but not the causes of the observed IPWP expansion, where expansion in the Indian Ocean has far exceeded that in the Pacific Ocean. We identify human and natural contributions to the observed IPWP changes since the 1950s by comparing observations with climate model simulations using an optimal fingerprinting technique. Greenhouse gas forcing is found to be the dominant cause of the observed increases in IPWP intensity and size, whereas natural fluctuations associated with the Pacific Decadal Oscillation have played a smaller yet significant role. Further, we show that the shape and impact of human-induced IPWP growth could be asymmetric between the Indian and Pacific basins, the causes of which remain uncertain. Human-induced changes in the IPWP have important implications for understanding and projecting related changes in monsoonal rainfall, and frequency or intensity of tropical storms, which have profound socioeconomic consequences.

    The stress -vulnerability model (Zubin et al. 1977) is an extremely useful model for identifying and treating relapses of mental illness. We accept that human persons carry genetic and other predisposition to mental illness. However, the question arises as to how stress impacts on a person in order to cause mental illness to develop. Furthermore there arises the issue as to what other effects such stress has on the human body beyond the human brain. Our aim was to research and integrate the current literature in order to establish how stress impacts on the brain at the cellular level, and to establish whether there are other consequences for the human body brought about by the impact of stress on the human brain. Literature Search, using pubmed. We have identified much literature on how stress affects biological mechanisms within the brain, and how it relates to biological vulnerabilities carried by different individuals. We have identified communalities in how the interplay between stress and vulnerability occurs in different disease processes.

    Chronic diseases are a leading contributor to work disability and job loss in Europe. Recent EU policies aim to improve job retention among chronically ill employees. Disability and occupational health researchers argue that this requires a coordinated and pro-active approach at the workplace by occupational health professionals, line managers (LMs) and human resource managers (HRM). Little is known about the perspectives of LMs an HRM on what is needed to facilitate job retention among chronically ill employees. The aim of this qualitative study was to explore and compare the perspectives of Dutch LMs and HRM on this issue. Concept mapping methodology was used to elicit and map statements (ideas) from 10 LMs and 17 HRM about what is needed to ensure continued employment for chronically ill employees. Study participants were recruited through a higher education and an occupational health services organization. Participants generated 35 statements. Each group (LMs and HRM) sorted these statements into six thematic clusters. LMs and HRM identified four similar clusters: LMs and HRM must be knowledgeable about the impact of chronic disease on the employee; employees must accept responsibility for work retention; work adaptations must be implemented; and clear company policy. Thematic clusters identified only by LMs were: good manager/employee cooperation and knowledge transfer within the company. Unique clusters identified by HRM were: company culture and organizational support. There were both similarities and differences between the views of LMs and HRM on what may facilitate job retention for chronically ill employees. LMs perceived manager/employee cooperation as the most important mechanism for enabling continued employment for these employees. HRM perceived organizational policy and culture as the most important mechanism. The findings provide information about topics that occupational health researchers and planners should address in developing job retention

  9. Ill-posedness in modeling mixed sediment river morphodynamics

    Chavarrías, Víctor; Stecca, Guglielmo; Blom, Astrid

    2018-04-01

    In this paper we analyze the Hirano active layer model used in mixed sediment river morphodynamics concerning its ill-posedness. Ill-posedness causes the solution to be unstable to short-wave perturbations. This implies that the solution presents spurious oscillations, the amplitude of which depends on the domain discretization. Ill-posedness not only produces physically unrealistic results but may also cause failure of numerical simulations. By considering a two-fraction sediment mixture we obtain analytical expressions for the mathematical characterization of the model. Using these we show that the ill-posed domain is larger than what was found in previous analyses, not only comprising cases of bed degradation into a substrate finer than the active layer but also in aggradational cases. Furthermore, by analyzing a three-fraction model we observe ill-posedness under conditions of bed degradation into a coarse substrate. We observe that oscillations in the numerical solution of ill-posed simulations grow until the model becomes well-posed, as the spurious mixing of the active layer sediment and substrate sediment acts as a regularization mechanism. Finally we conduct an eigenstructure analysis of a simplified vertically continuous model for mixed sediment for which we show that ill-posedness occurs in a wider range of conditions than the active layer model.

    Influenza causes significant morbidity and mortality, with considerable economic costs, including lost work productivity. Influenza vaccines may reduce the economic burden through primary prevention of influenza and reduction in illness severity. We examined illness severity and work productivity loss among working adults with medically attended acute respiratory illnesses and compared outcomes for subjects with and without laboratory-confirmed influenza and by influenza vaccination status among subjects with influenza during the 2012-2013 influenza season. Illnesses laboratory-confirmed as influenza (ie, cases) were subjectively assessed as more severe than illnesses not caused by influenza (ie, noncases) based on multiple measures, including current health status at study enrollment (≤7 days from illness onset) and current activity and sleep quality status relative to usual. Influenza cases reported missing 45% more work hours (20.5 vs 15.0; P productivity as impeded to a greater degree (6.0 vs 5.4; P productivity loss were noted for vaccinated subjects. Influenza illnesses were more severe and resulted in more missed work hours and productivity loss than illnesses not confirmed as influenza. Modest reductions in illness severity for vaccinated cases were observed. These findings highlight the burden of influenza illnesses and illustrate the importance of laboratory confirmation of influenza outcomes in evaluations of vaccine effectiveness. © The Author 2015.

    Full Text Available Introduction: Chronic cough may represent a diagnostic challenge. Chronic parasitism of upper airways is an unusual cause. Objective: To describe a case of human syngamosis as an uncommon cause of dry cough. Case Report: An endoscopic exam performed in a woman suffering of chronic cough revealed a Y-shaped worm in the larynx identified as Syngamus laryngeus. Discussion: This nematode parasitizes the upper respiratory tract of many animals including humans. The diagnosis is performed by the examination of the worm expelled by cough or by endoscopy. Endoscopic exam is easy to perform and is essential in the diagnosis of causes of chronic cough, even uncommon entities. Removal is the only efficient treatment.

    Simpson, Jane; Lekwuwa, Godwin; Crawford, Trevor

    2013-06-01

    Illness beliefs are important predictors of psychological outcome in people with chronic illness and evidence suggests these could also be significant in furthering our understanding of psychological functioning in people with Parkinson's disease. Illness beliefs are specific, dynamic representations of an illness and cover dimensions such as cause, identity, consequences and controllability. Eighty-one people with Parkinson's disease completed a series of questionnaires to provide demographic, clinical and psychosocial data, which were then used to assess the relative impact of illness beliefs on their psychological functioning. Psychological functioning was assessed by measuring levels of depression, anxiety, stress, positive affect and emotional well-being. Hierarchical block regression indicated that illness beliefs were important independent predictors across some but not all outcomes and the results emphasised the importance of testing new predictors against more established predictors of outcome such as physical functioning and self-esteem. The illness beliefs most important in psychological outcome in people with PD were causal beliefs (particularly in psychosocial causes) and illness coherence (the level of understanding of the illness). The therapeutic potential of psychosocial variables was discussed given that these can be modified during therapy and this change can positively influence psychological outcome.

    The presence of respiratory fungal infection in the critically ill patient is associated with high morbidity and mortality. To assess the incidence of respiratory infection caused by Aspergillus spp. independently of the origin of infection in patients admitted to Spanish ICUs, as well as to describe the rates, characteristics, outcomes and prognostic factors in patients with this type of infection. An observational, retrospective, open-label and multicenter study was carried out in a cohort of patients with respiratory infection caused by Aspergillus spp. admitted to Spanish ICUs between 2006 and 2012 (months of April, May and June), and included in the ENVIN-HELICS registry (108,244 patients and 825,797 days of ICU stay). Variables independently related to in-hospital mortality were identified by multiple logistic regression analysis. A total of 267 patients from 79 of the 198 participating ICUs were included (2.46 cases per 1000 ICU patients and 3.23 episodes per 10,000 days of ICU stay). From a clinical point of view, infections were classified as ventilator-associated pneumonia in 93 cases (34.8%), pneumonia unrelated to mechanical ventilation in 120 cases (44.9%), and tracheobronchitis in 54 cases (20.2%). The study population included older patients (mean 64.8±17.1 years), with a high severity level (APACHE II score 22.03±7.7), clinical diseases (64.8%) and prolonged hospital stay before the identification of Aspergillus spp. (median 11 days), transferred to the ICU mainly from hospital wards (58.1%) and with high ICU (57.3%) and hospital (59.6%) mortality rates, exhibiting important differences depending on the type of infection involved. Independent mortality risk factors were previous admission to a hospital ward (OR=7.08, 95%CI: 3.18-15.76), a history of immunosuppression (OR=2.52, 95%CI: 1.24-5.13) and severe sepsis or septic shock (OR=8.91, 95%CI: 4.24-18.76).

    Data published in 1999 from the Government Actuary on the National Health Service Pension Scheme (1989-1994) have indicated that the frequency of ill health premature retirement (IHR) was four times more prevalent among dentists at age 42 years compared with doctors.Objective The aim of this project was to determine the factors that contributed to IHR in dental practitioners, and the effects of IHR on their lives. Semi-structured interviews were carried out during 2007. A topic list was developed, piloted and used to guide the interviewer. A purposive sampling technique was used to recruit the respondents from an insurance company database. A framework approach to data analysis was utilised. Twenty-three respondents were interviewed, 19 male and 4 female, aged between 39-59 years. Depression, stress and anxiety were reported by respondents to be major causes of their retirement, followed by musculoskeletal disease and premature disability caused by trauma. This is illustrated by the following: '...just went straight into general practice but with some regrets. Practice was so depressing' (GDS/NHS); 'I withdraw, I don't engage ... I found it more and more difficult and one morning... I collapsed in tears at the practice' (GDS/NHS). Dentists reported both negative and positive comments in relation to support received from their health insurance company. The main causes of IHR were depression, musculoskeletal disease and specific skin conditions. Respondents expressed concern regarding the level of support available to dentists in distress. Respondents to this study found that continuing to work had a positive impact on their health.

    On July 8, 2014, the Colorado Department of Public Health and Environment (CDPHE) laboratory identified Yersinia pestis, the bacterium that causes plague, in a blood specimen collected from a man (patient A) hospitalized with pneumonia. The organism had been previously misidentified as Pseudomonas luteola by an automated system in the hospital laboratory. An investigation led by Tri-County Health Department (TCHD) revealed that patient A's dog had died recently with hemoptysis. Three other persons who had contact with the dog, one of whom also had contact with patient A, were ill with fever and respiratory symptoms, including two with radiographic evidence of pneumonia. Specimens from the dog and all three human contacts yielded evidence of acute Y. pestis infection. One of the pneumonia cases might have resulted through human-to-human transmission from patient A, which would be the first such event reported in the United States since 1924. This outbreak highlights 1) the need to consider plague in the differential diagnosis of ill domestic animals, including dogs, in areas where plague is endemic; 2) the limitations of automated diagnostic systems for identifying rare bacteria such as Y. pestis; and 3) the potential for milder plague illness in patients taking antimicrobial agents. Hospital laboratorians should be aware of the limitations of automated identification systems, and clinicians should suspect plague in patients with clinically compatible symptoms from whom P. luteola is isolated.

    1994-04-01

    We investigated cultural diversity in beliefs about the causes of illness and assessed the possibility that popular free-form methodologies (asking subjects to generate causes) inhibit minorities from expressing their belief in supernatural causes. As predicted, when asked to generate causes of illness and rate these in terms of their importance, whites and minorities did not differ in the number or type (natural vs supernatural) of causes they generated or in the importance rating they assigned to these. However, when these same subjects were provided with natural and supernatural causes to rate in terms of importance, minorities rated supernatural causes significantly more important than did whites, and more minorities than whites endorsed such causes. Cultural differences in causal attributions for illness are examined, and the role of methodology in determining such attributions is highlighted.

  20. Human-specific HERV-K insertion causes genomic variations in the human genome.

    Directory of Open Access Journals (Sweden)

    Wonseok Shin

    Full Text Available Human endogenous retroviruses (HERV sequences account for about 8% of the human genome. Through comparative genomics and literature mining, we identified a total of 29 human-specific HERV-K insertions. We characterized them focusing on their structure and flanking sequence. The results showed that four of the human-specific HERV-K insertions deleted human genomic sequences via non-classical insertion mechanisms. Interestingly, two of the human-specific HERV-K insertion loci contained two HERV-K internals and three LTR elements, a pattern which could be explained by LTR-LTR ectopic recombination or template switching. In addition, we conducted a polymorphic test and observed that twelve out of the 29 elements are polymorphic in the human population. In conclusion, human-specific HERV-K elements have inserted into human genome since the divergence of human and chimpanzee, causing human genomic changes. Thus, we believe that human-specific HERV-K activity has contributed to the genomic divergence between humans and chimpanzees, as well as within the human population.

    Recent studies have shown that the claim that King George III suffered from acute porphyria is seriously at fault. This article explores some of the causes of this misdiagnosis and the consequences of the misleading claims, also reporting on the nature of the king's recurrent mental illness according to computer diagnostics. In addition, techniques of cognitive archaeology are used to investigate the nature of the king's final decade of mental illness, which resulted in the appointment of the Prince of Wales as Prince Regent. The results of this analysis confirm that the king suffered from bipolar disorder type I, with a final decade of dementia, due, in part, to the neurotoxicity of his recurrent episodes of acute mania. © 2015 Royal College of Physicians.

    Full Text Available Background: Illness uncertainty is a source of a chronic and pervasive psychological stress for people living with human immunodeficiency virus (HIV/acquired immune deficiency syndrome (AIDS (PLWH, and largely affects their quality of life and the ability to cope with the disease. Based on the uncertainty in illness theory, the social support is one of the illness uncertainty antecedents, and influences the level of uncertainty perceived by patients. Aim: To examine uncertainty in PLWH and its correlation with social support in Iran. Materials and Methods: This cross-sectional correlational study was conducted with 80 PLWH presenting to AIDS Research Center, Tehran, Iran in 2013. The data collected using illness uncertainty and social support inventories were analyzed through Pearson′s correlation coefficient, Spearman′s correlation coefficient, and regression analysis. Results: The results showed a high level of illness uncertainty in PLWH and a negative significant correlation between perceived social support and illness uncertainty ( P = 0.01, r = -0.29. Conclusion: Uncertainty is a serious aspect of illness experience in Iranian PLWH. Providing adequate, structured information to patients as well as opportunities to discuss their concerns with other PLWH and receive emotional support from their health care providers may be worthwhile.

We identified acute dengue (serotypes 1 and 2 in 38 (5.1% patients. Only 8.1% (3/37 of confirmed cases were suspected clinically.Dengue is an important and largely unrecognized cause of fever in rural western Nicaragua. Since Zika virus is transmitted by the same vector and has been associated with severe congenital infections, the population we studied is at particular risk for being devastated by the Zika epidemic that has now reached Central America.

  5. Decompression illness - critical review

    Directory of Open Access Journals (Sweden)

    C S Mohanty

    2015-01-01

    Full Text Available Decompression illness is caused by intravascular or extravascular bubbles that are formed as a result of reduction in environmental pressure (decompression. The term covers both arterial gas embolism, in which alveolar gas or venous gas emboli (via cardiac shunts or via pulmonary vessels are introduced into the arterial circulation, and decompression sickness, which is caused by in-situ bubble formation from dissolved inert gas. Both syndromes can occur in divers, compressed air workers, aviators, and astronauts, but arterial gas embolism also arises from iatrogenic causes unrelated to decompression. Risk of decompression illness is affected by immersion, exercise, and heat or cold. Manifestations range from itching and minor pain to neurological symptoms, cardiac collapse, and death. First-aid treatment is 1 0 0 % oxygen and definitive treatment is recompression to increased pressure, breathing 1 0 0 % oxygen. Adjunctive treatment, including fluid administration and prophylaxis against venous thromboembolism in paralysed patients, is also recommended Treatment is, in most cases, effective although residual deficits can remain in serious cases, even after several recompressions.

    Algal blooms of Karenia brevis, a harmful marine algae, occur almost annually off the west coast of Florida. At high concentrations, K. brevis blooms can cause harm through the release of potent toxins, known as brevetoxins, to the atmosphere. Epidemiologic studies suggest that aerosolized brevetoxins are linked to respiratory illnesses in humans. We hypothesized a relationship between K. brevis blooms and respiratory illness visits to hospital emergency departments (EDs) while controlling for environmental factors, disease, and tourism. We sought to use this relationship to estimate the costs of illness associated with aerosolized brevetoxins. We developed a statistical exposure-response model to express hypotheses about the relationship between respiratory illnesses and bloom events. We estimated the model with data on ED visits, K. brevis cell densities, and measures of pollen, pollutants, respiratory disease, and intra-annual population changes. We found that lagged K. brevis cell counts, low air temperatures, influenza outbreaks, high pollen counts, and tourist visits helped explain the number of respiratory-specific ED diagnoses. The capitalized estimated marginal costs of illness for ED respiratory illnesses associated with K. brevis blooms in Sarasota County, Florida, alone ranged from $0.5 to $4 million, depending on bloom severity. Blooms of K. brevis lead to significant economic impacts. The costs of illness of ED visits are a conservative estimate of the total economic impacts. It will become increasingly necessary to understand the scale of the economic losses associated with K. brevis blooms to make rational choices about appropriate mitigation.

    In Australia circa 2010, 4.1 million (90% credible interval [CrI] 2.3-6.4 million) episodes of foodborne gastroenteritis occurred, many of which might have resulted in sequelae. We estimated the number of illnesses, hospitalizations, and deaths from Guillain-Barré syndrome, hemolytic uremic syndrome, irritable bowel syndrome, and reactive arthritis that were associated with contaminated food in Australia. Data from published studies, hospital records, and mortality reports were combined with multipliers to adjust for different transmission routes. We used Monte Carlo simulation to estimate median estimates and 90% CrIs. In Australia, circa 2010, we estimated that 35,840 (90% CrI 25,000-54,000) illnesses, 1,080 (90% CrI 700-1,600) hospitalizations, and 10 (90% CrI 5-14) deaths occurred from foodborne gastroenteritis-associated sequelae. Campylobacter spp. infection was responsible for 80% of incident cases. Reducing the incidence of campylobacteriosis and other foodborne diseases would minimize the health effects of sequelae.

    Full Text Available Many of the symptoms of Gulf War Illness (GWI that include neurological abnormalities, neuroinflammation, chronic fatigue and gastrointestinal disturbances have been traced to Gulf War chemical exposure. Though the association and subsequent evidences are strong, the mechanisms that connect exposure to intestinal and neurological abnormalities remain unclear. Using an established rodent model of Gulf War Illness, we show that chemical exposure caused significant dysbiosis in the gut that included increased abundance of phylum Firmicutes and Tenericutes, and decreased abundance of Bacteroidetes. Several gram negative bacterial genera were enriched in the GWI-model that included Allobaculum sp. Altered microbiome caused significant decrease in tight junction protein Occludin with a concomitant increase in Claudin-2, a signature of a leaky gut. Resultant leaching of gut caused portal endotoxemia that led to upregulation of toll like receptor 4 (TLR4 activation in the small intestine and the brain. TLR4 knock out mice and mice that had gut decontamination showed significant decrease in tyrosine nitration and inflammatory mediators IL1β and MCP-1 in both the small intestine and frontal cortex. These events signified that gut dysbiosis with simultaneous leaky gut and systemic endotoxemia-induced TLR4 activation contributes to GW chemical-induced neuroinflammation and gastrointestinal disturbances.

    This paper describes the first methodology and results for estimating the order of probability for Tasers directly causing human ventricular fibrillation (VF). The probability of an X26 Taser causing human VF was estimated using: (1) current density near the human heart estimated by using 3D finite-element (FE) models; (2) prior data of the maximum dart-to-heart distances that caused VF in pigs; (3) minimum skin-to-heart distances measured in erect humans by echocardiography; and (4) dart landing distribution estimated from police reports. The estimated mean probability of human VF was 0.001 for data from a pig having a chest wall resected to the ribs and 0.000006 for data from a pig with no resection when inserting a blunt probe. The VF probability for a given dart location decreased with the dart-to-heart horizontal distance (radius) on the skin surface.

    To evaluate the use of human albumin in critically ill dogs. Design-Retrospective case series. 73 client-owned hospitalized dogs. Medical records of dogs that received human albumin were reviewed to assess effects of the use of human albumin on serum albumin concentration, colloid osmotic pressure, and total protein concentration; determine the relationships between these variables and outcome; and assess its safety. Data for signalment, diagnoses, physiologic variables, dosage, amount of crystalloid fluid administered prior to human albumin administration, complications, and outcome were reviewed. Additionally, pre- and postadministration values for serum albumin, colloid osmotic pressure, and total protein were recorded. Administration of human albumin resulted in significant changes in serum albumin, colloid osmotic pressure, and total protein. The serum albumin, total protein, degree of improvement in serum albumin, colloid osmotic pressure, and dosage of human albumin were significantly greater in survivors. Seventeen of 73 (23%) dogs had at least 1 complication that could be potentially associated with the administration of human albumin that occurred during or immediately following administration of human albumin. Three of 73 (4%) dogs had severe delayed complications. Administration of human albumin significantly increased serum albumin, and total protein concentrations and colloid osmotic pressure, especially in survivors. Because of the high mortality rate of the study population and other confounding factors, it was uncertain whether complications were associated with the underlying disease or with human albumin administration. Acute and delayed complications may have been under-recognized.

    The purpose of the study is to document in Hong Kong Chinese cancer survivors cross-sectional associations between illness perceptions, physical symptom distress and dispositional optimism. A consecutive sample of 1036 (response rate, 86.1%, mean age 55.18 years, 60% female) survivors of different cancers recruited within 6 months of completion of adjuvant therapy from Hong Kong public hospitals completed the Brief Illness Perception Questionnaire (B-IPQ), Chinese version of the Memorial Symptom Assessment Scale Short-Form (MSAS-SF), and the revised Chinese version of Life Orientation Test (C-LOT-R), respectively. Stepwise multiple regression analyses examined adjusted associations. IPQ seriousness, symptom identity, illness concern, and emotional impact scores varied by cancer type (p Stress-related, lifestyle, environment, psychological/personality, and health-related factors were most frequently attributed causes of cancer. After adjustment for sample differences, physical symptom distress was significantly associated with all illness perception dimensions (p differences by cancer type were eliminated by adjustment for sample characteristics. Illness perceptions did not differ by cancer type. Greater physical symptom distress and lower levels of optimism were associated with more negative illness perceptions. Understanding how cancer survivors make sense of cancer can clarify an important aspect of adaptation. This in turn can inform interventions to facilitate adjustment. Knowledge contributions include evidence of physical symptom distress correlating with most dimensions of illness perception. Optimism was also associated with cancer survivors' illness perceptions.

    Full Text Available OBJECTIVES Recently kudoa septempuctata in olive flounders is suggested as a cause of food poisoning, however whether kudoa septempuctata can affect human gastrointestinal systems is controversial and its pathogenecity remains unclear. In view of the field epidemiology, food poisonings caused by kudoa septempuctata should be distinguished from those caused by Staphylococcus aureus and bacillus cereus. METHODS The statistics of food poisoning investigations published by Korea Centers for Disease Control and Prevention in 2013-2015 were reviewed. The characteristics of kudoa septempuctata food poisoning reported by Korea Centers for Disease Control and Prevention were reviewed. Information regarding clinical symptoms or epidemiology was extracted. RESULTS Total eleven kudoa septempuctata food poisoning cases were analyzed. Food poisonings caused by kudoa septempuctata, Staphylococcus aureus and bacillus cereus have clinical and epidemiological similarities. Forty five percent of food poisoning outbreaks occurred in Korea was concluded as unknown. The food poisoning caused by Staphylococcus aureus and bacillus cereus accounted for 4.5% (50/1,092 of all food poisoning outbreaks in Korea between 2013 and 2015. CONCLUSIONS This study suggests the possibilities of misdiagnosis in the investigations of food poisoning by Staphylococcus aureus and bacillus cereus with kudoa septempuctata.

    There is evidence showing an increasing prevalence of mental illness in those in conflict with the law. However, there are many factors affecting the detection, treatment, and management of criminals who are mentally ill. Sex offenders with major mental illness present many challenges to those providing treatment and management services. For example, it is important to consider whether sexually offensive behavior is the cause of criminal behavior or whether it is reflective of an antisocial orientation. Recent evidence suggests it may help better understand and inform risk assessment and management. This paper will review the literature on mental illness among sexual offenders, present a typology to aid in the assessment, treatment, and management of sexual offender with mental illness, and highlight important considerations when providing treatment to sexual offenders with mental illness.

    Full Text Available One of the core concerns of medical anthropology is to explore how people in different cultures and social groups explain the causes of ill health, the type of treatment they believe in, and to whom they turn if they do become ill. This article focuses on the understanding of illness causation by the Newars in Kirtipur and their concern about biological and socio-cultural aspects of healthy behavior, and particularly with the ways in which they have been coping in everyday life. The basic method of data collection for this study was formal and informal discussions with the elderly Newar males and females, followed by discussions with youths to explore the variations in their perceptions. The findings show that the understanding of illness etiology is multi-causal. The individual, natural, social, and supernatural causes are not mutually exclusive but are usually linked together in a particular case. In any specific case of illness, moreover, people’s explanatory model varies in how they explain its etiology.DOI: http://dx.doi.org/10.3126/dsaj.v5i0.6358 Dhaulagiri Journal of Sociology and Anthropology Vol. 5, 2011: 101-120    

  1. Foodborne illness: new developments concerning an old problem.

    2002-08-01

    Foodborne illnesses continue to cause substantial morbidity and mortality in the United States, primarily as gastroenteritis but occasionally as other syndromes as well. Most of these illnesses are caused by a variety of widely known infectious agents, principally viruses, and are probably the result of common mistakes in food handling in the home or in restaurants. The epidemiology of foodborne illness is evolving. Major changes in food production, distribution, and consumption have created opportunities for new pathogens to emerge and for old ones to reemerge, and the potential for widespread outbreaks is increasing. Antibiotic resistance in bacterial pathogens resulting from the widespread use of antimicrobial agents in animal husbandry is also an important concern. Clinicians must be aware of the changing epidemiology of foodborne illness to recognize and manage these conditions in the clinical setting. In addition, clinicians are critical in the reporting of recognized or suspected foodborne illness, so that public health authorities are able to investigate, understand, and ultimately better control them. A number of new techniques have been employed, and others under development will improve our ability to recognize and cope with foodborne diseases.

    Ethical controversy surrounds clinical research involving seriously ill participants. While many stakeholders have opinions, the extent to which protocol volunteers themselves see human research as ethically acceptable has not been documented. To address this gap of knowledge, authors sought to assess views of healthy and ill clinical research volunteers regarding the ethical acceptability of human studies involving individuals who are ill or are potentially vulnerable. Surveys and semi-structured interviews were used to query clinical research protocol participants and a comparison group of healthy individuals. A total of 179 respondents participated in this study: 150 in protocols (60 mentally ill, 43 physically ill, and 47 healthy clinical research protocol participants) and 29 healthy individuals not enrolled in protocols. Main outcome measures included responses regarding ethical acceptability of clinical research when it presents significant burdens and risks, involves people with serious mental and physical illness, or enrolls people with other potential vulnerabilities in the research situation. Respondents expressed decreasing levels of acceptance of participation in research that posed burdens of increasing severity. Participation in protocols with possibly life-threatening consequences was perceived as least acceptable (mean = 1.82, sd = 1.29). Research on serious illnesses, including HIV, cancer, schizophrenia, depression, and post-traumatic stress disorder, was seen as ethically acceptable across respondent groups (range of means = [4.0, 4.7]). Mentally ill volunteers expressed levels of ethical acceptability for physical illness research and mental illness research as acceptable and similar, while physically ill volunteers expressed greater ethical acceptability for physical illness research than for mental illness research. Mentally ill, physically ill, and healthy participants expressed neutral to favorable perspectives regarding the ethical

    2017-08-01

    Brucellosis, Q fever and melioidosis are zoonoses, which can lead to pyrexia. These diseases are often under-ascertained and underreported because of their unspecific clinical signs and symptoms, insufficient awareness by physicians and public health officers and limited diagnostic capabilities, especially in low-resource countries. Therefore, the presence of Brucella spp., Coxiella burnetii and Burkholderia pseudomallei was investigated in Malagasy patients exhibiting febrile illness. In addition, we analyzed zebu cattle and their ticks as potential reservoirs for Brucella and C. burnetii, respectively. Specific quantitative real-time PCR assays (qPCRs) were performed on 1020 blood samples drawn from febrile patients. In total, 15 samples (1.5%) were Brucella-positive, mainly originating from patients without travel history, while DNA from C. burnetii and Bu. pseudomallei was not detected. Anti-C. burnetii antibodies were found in four out of 201 zebu serum samples (2%), whereas anti-Brucella antibodies could not be detected. Brucella DNA was detected in a single zebu sample. Three out of 330 ticks analyzed (1%) were positively tested for C. burnetii DNA but with high Ct values in the qPCR assay. Our data suggest that zebus as well as Amblyomma and Boophilus ticks have to be considered as a natural reservoir or vector for C. burnetii, but the risk of cattle-to-human transmission is low. Since bovine brucellosis does not seem to contribute to human infections in Madagascar, other transmission routes have to be assumed. Copyright © 2017 The Authors. Published by Elsevier B.V.

  5. New frontiers in animal research of psychiatric illness.

    Alterations in neurodevelopment are thought to modify risk of numerous psychiatric disorders, including schizophrenia, autism, ADHD, mood and anxiety disorders, and substance abuse. However, little is known about the cellular and molecular changes that guide these neurodevelopmental changes and how they contribute to mental illness. In this review, we suggest that elucidating this process in humans requires the use of model organisms. Furthermore, we advocate that such translational work should focus on the role that genes and/or environmental factors play in the development of circuits that regulate specific physiological and behavioral outcomes in adulthood. This emphasis on circuit development, as a fundamental unit for understanding behavior, is distinct from current approaches of modeling psychiatric illnesses in animals in two important ways. First, it proposes to replace the diagnostic and statistical manual of mental disorders (DSM) diagnostic system with measurable endophenotypes as the basis for modeling human psychopathology in animals. We argue that a major difficulty in establishing valid animal models lies in their reliance on the DSM/International Classification of Diseases conceptual framework, and suggest that the Research Domain Criteria project, recently proposed by the NIMH, provides a more suitable system to model human psychopathology in animals. Second, this proposal emphasizes the developmental origin of many (though clearly not all) psychiatric illnesses, an issue that is often glossed over in current animal models of mental illness. We suggest that animal models are essential to elucidate the mechanisms by which neurodevelopmental changes program complex behavior in adulthood. A better understanding of this issue, in animals, is the key for defining human psychopathology, and the development of earlier and more effective interventions for mental illness.

  6. High altitude illness

    Hartman-Ksycińska, Anna; Kluz-Zawadzka, Jolanta; Lewandowski, Bogumił

    High-altitude illness is a result of prolonged high-altitude exposure of unacclimatized individuals. The illness is seen in the form of acute mountain sickness (AMS) which if not treated leads to potentially life-threatening high altitude pulmonary oedema and high-altitude cerebral oedema. Medical problems are caused by hypobaric hypoxia stimulating hypoxia-inducible factor (HIF) release. As a result, the central nervous system, circulation and respiratory system function impairment occurs. The most important factor in AMS treatment is acclimatization, withdrawing further ascent and rest or beginning to descent; oxygen supplementation, and pharmacological intervention, and, if available, a portable hyperbaric chamber. Because of the popularity of high-mountain sports and tourism better education of the population at risk is essential.

    Background Arthropod-borne viruses (arboviruses) are among the most common agents of human febrile illness worldwide and the most important emerging pathogens, causing multiple notable epidemics of human disease over recent decades. Despite the public health relevance, little is know about the geographic distribution, relative impact, and risk factors for arbovirus infection in many regions of the world. Our objectives were to describe the arboviruses associated with acute undifferentiated febrile illness in participating clinics in four countries in South America and to provide detailed epidemiological analysis of arbovirus infection in Iquitos, Peru, where more extensive monitoring was conducted. Methodology/Findings A clinic-based syndromic surveillance system was implemented in 13 locations in Ecuador, Peru, Bolivia, and Paraguay. Serum samples and demographic information were collected from febrile participants reporting to local health clinics or hospitals. Acute-phase sera were tested for viral infection by immunofluorescence assay or RT-PCR, while acute- and convalescent-phase sera were tested for pathogen-specific IgM by ELISA. Between May 2000 and December 2007, 20,880 participants were included in the study, with evidence for recent arbovirus infection detected for 6,793 (32.5%). Dengue viruses (Flavivirus) were the most common arbovirus infections, totaling 26.0% of febrile episodes, with DENV-3 as the most common serotype. Alphavirus (Venezuelan equine encephalitis virus [VEEV] and Mayaro virus [MAYV]) and Orthobunyavirus (Oropouche virus [OROV], Group C viruses, and Guaroa virus) infections were both observed in approximately 3% of febrile episodes. In Iquitos, risk factors for VEEV and MAYV infection included being male and reporting to a rural (vs urban) clinic. In contrast, OROV infection was similar between sexes and type of clinic. Conclusions/Significance Our data provide a better understanding of the geographic range of arboviruses in South

    The Chinese boreal forest is an important forest resource in China. However, it has been suffering serious disturbances of forest fires, which were caused equally by natural disasters (e.g., lightning) and human activities. The literature on human-caused fires indicates that climate, topography, vegetation, and human infrastructure are significant factors that impact the occurrence and spread of human-caused fires. But the studies on human-caused fires in the boreal forest of northern China are limited and less comprehensive. This paper applied the spatial analysis tools in ArcGIS 10.0 and Logistic regression model to investigate the driving factors of human-caused fires. Our data included the geographic coordinates of human-caused fires, climate factors during year 1974-2009, topographic information, and forest map. The results indicated that distance to railway (x1) and average relative humidity (x2) significantly impacted the occurrence of human-caused fire in the study area. The logistic model for predicting the fire occurrence probability was formulated as P= 1/[11+e-(3.026-0.00011x1-0.047x2)] with an accuracy rate of 80%. The above model was used to predict the monthly fire occurrence during the fire season of 2015 based on the HADCM2 future weather data. The prediction results showed that the high risk of human-caused fire occurrence concentrated in the months of April, May, June and August, while April and May had higher risk of fire occurrence than other months. According to the spatial distribution of possibility of fire occurrence, the high fire risk zones were mainly in the west and southwest of Tahe, where the major railways were located.

    Acute respiratory illnesses (ARI), comprising influenza-like illness (ILI) and other wintertime respiratory illnesses (ORI), impose substantial health and economic burdens on the United States. Little is known about the impact of ILI among household members (HHM), particularly children, on employees' productivity. To quantify the impact of employee and HHM-ILI and ARI on employee productivity, a prospective, observational cohort study was conducted among employees from three large US companies. Employees who had at least one child living at home (N=2013) completed a monthly survey during the 2007-2008 influenza season, reporting the number of days missed from work and hours of presenteeism due to: (1) personal ILI, (2) HHM-ILI, and (3) personal and HHM-ARI. Employee ILI ranged from 4.8% (April) to 13.5% (February). Employees reporting ILI reported more absences than employees not reporting ILI (72% vs 30%, respectively; Pemployees surveyed had at least one child with an ILI; these employees missed more days of work due to HHM illness than employees without an ARI-ill child (0.9 days vs 0.3 days, respectively; PEmployees with ILI were less productive, on average, for 4.8h each day that they worked while sick, 2.5h of which was attributable to ILI. HHM illnesses accounted for 17.7% (1389/7868 days) of employee absenteeism, over half of which was due to HHM-ARI. ILI causes a significant amount of employee absence. Household members, particularly children, comprise a sizable proportion of general illness and injury-related employee absences. Copyright 2010 Elsevier Ltd. All rights reserved.

    Identifying factors that facilitate treatment for psychotic disorders among Chinese-immigrants is crucial due to delayed treatment use. Identifying causal beliefs held by relatives that might predict identification of 'mental illness' as opposed to other 'indigenous labels' may promote more effective mental health service use. We examine what effects beliefs of 'physical causes' and other non-biomedical causal beliefs ('general social causes', and 'indigenous Chinese beliefs' or culture-specific epistemologies of illness) might have on mental illness identification. Forty-nine relatives of Chinese-immigrant consumers with psychosis were sampled. Higher endorsement of 'physical causes' was associated with mental illness labeling. However among the non-biomedical causal beliefs, 'general social causes' demonstrated no relationship with mental illness identification, while endorsement of 'indigenous Chinese beliefs' showed a negative relationship. Effective treatment- and community-based psychoeducation, in addition to emphasizing biomedical models, might integrate indigenous Chinese epistemologies of illness to facilitate rapid identification of psychotic disorders and promote treatment use.

    Developmental and physiological changes in children contribute to variation in drug disposition with age. Additionally, critically ill children suffer from various life-threatening conditions that can lead to pathophysiological alterations that further affect pharmacokinetics (PK). Some factors that can alter PK in this patient population include variability in tissue distribution caused by protein binding changes and fluid shifts, altered drug elimination due to organ dysfunction, and use of medical interventions that can affect drug disposition (e.g., extracorporeal membrane oxygenation and continuous renal replacement therapy). Performing clinical studies in critically ill children is challenging because there is large inter-subject variability in the severity and time course of organ dysfunction; some critical illnesses are rare, which can affect subject enrollment; and critically ill children usually have multiple organ failure, necessitating careful selection of a study design. As a result, drug dosing in critically ill children is often based on extrapolations from adults or non-critically ill children. Dedicated clinical studies in critically ill children are urgently needed to identify optimal dosing of drugs in this population. This review will summarize the effect of critical illness on pediatric PK, the challenges associated with performing studies in this vulnerable subpopulation, and the clinical PK studies performed to date for commonly used drugs.

    Enteroviruses can cause outbreaks of severe acute respiratory illness (SARI) and EV-A, -B, -C, and -D species have different pathogenic profiles and circulation patterns. We aimed to characterize and determine the prevalence of enterovirus genotypes among South African patients with respiratory illness and controls during June 2012 to July 2014. Syndromic SARI and influenza-like illness (ILI) surveillance was performed at two sentinel sites. At each site nasopharyngeal/oropharyngeal specimens were collected from SARI and ILI patients as well as controls. Specimens were tested for enterovirus by real-time PCR. Positive specimens were further genotyped by sequencing a region of the VP1 gene. The prevalence of enterovirus was 5.8% (87/1494), 3.4% (103/3079), and 3.4% (46/1367) among SARI, ILI, and controls, respectively (SARI/controls, P = 0.002 and ILI/control, P = 0.973). Among the 101/236 (42.8%) enterovirus-positive specimens that could be genotyped, we observed a high diversity of circulating enterovirus genotypes (a total of 33 genotypes) from all four human enterovirus species with high prevalence of Enterovirus-B (60.4%; 61/101) and Enterovirus-A (21.8%; 22/101) compared to Enterovirus-C (10.9%; 11/101) and Enterovirus-D (6.9%; 7/101) (P = 0.477). Of the enterovirus genotypes identified, Echovirus 30 (9.9%, 10/101), Coxsackie virus B5 (7.9%, 8/101) and Enterovirus-D68 (6.9%, 7/101) were most prevalent. There was no difference in disease severity (SARI or ILI compared to controls) between the different enterovirus species (P = 0.167). We observed a high number of enterovirus genotypes in patients with respiratory illness and in controls from South Africa with no disease association of EV species with disease severity. © 2017 Wiley Periodicals, Inc.

    2014-12-01

    The awareness of natural hazards has been up-trending in recent years. In particular, this is true for earthquakes, which increase in frequency and magnitude in regions that normally do not experience seismic activity. In fact, one of the major concerns for many communities and businesses is that humans today seem to cause earthquakes due to large-scale shale gas production, dewatering and flooding of mines and deep geothermal power production. Accordingly, without opposing any of these technologies it should be a priority of earth scientists who are researching natural hazards to communicate earthquake risks. This presentation discusses the challenges that earth scientists are facing to properly communicate earthquake risks, in light of the fact that human-caused earthquakes are an environmental change affecting only some communities and businesses. Communication channels may range from research papers, books and class room lectures to outreach events and programs, popular media events or even social media networks.

    Full Text Available Abstract Background Human bocavirus (HBoV is a newly discovered parvovirus associated with acute respiratory tract illness (ARTI and gastrointestinal illness. Our study is the first to analyze the characteristics of HBoV-positive samples from ARTI patients with a wide age distribution from Guangzhou, southern China. Methods Throat swabs (n=2811 were collected and analyzed from children and adults with ARTI over a 13-month period. The HBoV complete genome from a 60 year-old female patient isolate was also determined. Results HBoV DNA was detected in 65/2811 (2.3% samples, of which 61/1797 were from children (Mycoplasma pneumoniae had the highest frequency of 16.9% (11/65. Upper and lower respiratory tract illness were common symptoms, with 19/65 (29.2% patients diagnosed with pneumonia by chest radiography. All four adult patients had systemic influenza-like symptoms. Phylogenetic analysis of the complete genome revealed a close relationship with other HBoVs, and a more distant relationship with HBoV2 and HBoV3. Conclusions HBoV was detected from children and adults with ARTI from Guangzhou, southern China. Elderly people were also susceptive to HBoV. A single lineage of HBoV was detected among a wide age distribution of patients with ARTI.

    Acute flaccid paralysis (AFP) is a life-threatening clinical entity characterized by weakness in the whole body muscles often accompanied by respiratory and bulbar paralysis. The most common cause is Gullian-Barre syndrome, but infections, spinal cord diseases, neuromuscular diseases such as myasthenia gravis, drugs and toxins, periodic hypokalemic paralysis, electrolyte disturbances, and botulism should be considered as in the differential diagnosis. Human coronaviruses (HCoVs) cause common ...

    Verotoxigenic Escherichia coli infections in humans cause disease ranging from uncomplicated intestinal illnesses to bloody diarrhea and systemic sequelae, such as hemolytic uremic syndrome (HUS). Previous research indicated that pigeons may be a reservoir for a population of verotoxigenic E. coli producing the VT2f variant. We used whole-genome sequencing to characterize a set of VT2f-producing E. coli strains from human patients with diarrhea or HUS and from healthy pigeons. We describe a phage conveying the vtx2f genes and provide evidence that the strains causing milder diarrheal disease may be transmitted to humans from pigeons. The strains causing HUS could derive from VT2f phage acquisition by E. coli strains with a virulence genes asset resembling that of typical HUS-associated verotoxigenic E. coli. PMID:27584691

    Full Text Available The personalised nature of mental illness obscures from general view the intolerable burden of private and public distress that people with serious mental illness carry. Invariably the mentally ill person encounters rejection and humiliation that are in some way tantamount to a "second illness." The combination either disrupts or puts beyond reach the usual personal and social life stages of marriage, family life, raising children, sexual relationships, the choice of treatment, affordable housing, transportation, education and gainful employment. As a result of their lack of financial and social support and their experience of rejection from society, persons with mental illness tend to neglect themselves and their diet, and frequently delay seeking treatment. Against this background, this contribution critically focuses on the human rights that influence the mentally ill patient in South African medical law. Specific attention is paid to the relevance and meaning of sections 9 (the equality clause, 27 (access to health care services, 30 and 31 (language, culture and religion of the Constitution of the Republic of South Africa, 1996.

  4. Human error as the root cause of severe accidents at nuclear reactors

    2017-01-01

    A root cause is a factor inducing an undesirable event. It is feasible for root causes to be eliminated through technological process improvements. Human error was the root cause of all severe accidents at nuclear power plants. The TMI accident was caused by a series of human errors. The Chernobyl disaster occurred after a badly performed test of the turbogenerator at a reactor with design deficiencies, and in addition, the operators ignored the safety principles and disabled the safety systems. At Fukushima the tsunami risk was underestimated and the project failed to consider the specific issues of the site. The paper describes the severe accidents and points out the human errors that caused them. Also, provisions that might have eliminated those severe accidents are suggested. The fact that each severe accident occurred on a different type of reactor is relevant – no severe accident ever occurred twice at the same reactor type. The lessons learnt from the severe accidents and the safety measures implemented on reactor units all over the world seem to be effective. (orig.)

O aumento observado entre 1980 e 2002 na classificação de óbitos por causa mal definida pelo primeiro avaliador no Estado de São Paulo indica uma importante piora na qualidade do preenchimento da declaração de óbito nessa instância. São necessárias investigações adicionais para esclarecer as causas dessa mudança.OBJECTIVE: To investigate the proportion of deaths with an ill-defined cause in the Brazilian state of São Paulo between 1980 and 2002, taking into account the influence of autopsies on this proportion. METHOD: Data on the number of deaths were obtained from the Brazilian Ministry of Health. The communities of the state of São Paulo were divided into three groups: (1 municipalities with a service to verify the cause of death (and that may conduct an autopsy, (2 municipalities without a cause of death verification service, and (3 the region of Baixada Santista, which had an extremely large increase in the proportion of deaths from ill-defined causes between 1980 and 1995. The impact of autopsies on the proportion of deaths with an ill-defined cause was defined based on the classification made by the first physician evaluating the cause of death, that is, the physician who referred the case to the verification service for autopsy or who completed the death certificate without referring the case to the verification service. Deaths from external causes were excluded, since autopsy is mandatory in these cases. The following were evaluated: (1 proportion of cases classified by the first evaluating physician as having an ill-defined cause, (2 proportion of autopsies in relation to the total number of deaths (except from external causes, and (3 proportion of deaths classified as ill-defined by the first evaluating physician but explained by the autopsy. RESULTS: The proportion of deaths classified by the first evaluating physician as having an ill-defined cause increased over the 1980

Among the 101/236 (42.8%) enterovirus-positive specimens that could be genotyped, we observed a high diversity of circulating enterovirus genotypes (a total of 33 genotypes) from all four human enterovirus species with high prevalence of Enterovirus-B (60.4%; 61/101) and Enterovirus-A (21.8%; 22/101) compared to Enterovirus-C (10.9%; 11/101) and Enterovirus-D (6.9%; 7/101) (P = 0.477). Of the enterovirus genotypes identified, Echovirus 30 (9.9%, 10/101), Coxsackie virus B5 (7.9%, 8/101) and Enterovirus-D68 (6.9%, 7/101) were most prevalent. There was no difference in disease severity (SARI or ILI compared to controls) between the different enterovirus species (P = 0.167).We observed a high number of enterovirus genotypes in patients with respiratory illness and in controls from South Africa with no disease association of EV species with disease severity.

    The increasing interest in the genetic causes of mental disorders may exacerbate existing stigma if negative beliefs about a genetic illness are generally accepted. China's history of policy-level eugenics and genetic discrimination in the workplace suggests that Chinese communities will view genetic mental illness less favorably than mental illness with non-genetic causes. The aim of this study is to identify differences between Chinese Americans and European Americans in eugenic beliefs and stigma toward people with genetic mental illness. We utilized data from a 2003 national telephone survey designed to measure how public perceptions of mental illness differ if the illness is described as genetic. The Chinese American (n = 42) and European American (n = 428) subsamples were analyzed to compare their support of eugenic belief items and measures of stigma. Chinese Americans endorsed all four eugenic statements more strongly than European Americans. Ethnicity significantly moderated the relationship between genetic attribution and three out of five stigma outcomes; however, genetic attribution actually appeared to be de-stigmatizing for Chinese Americans while it increased stigma or made no difference for European Americans. Our findings show that while Chinese Americans hold more eugenic beliefs than European Americans, these attributions do not have the same effect on stigma as they do in Western cultures. These results suggest that future anti-stigma efforts must focus on eugenic attitudes as well as cultural beliefs for Chinese Americans, and that the effects of genetic attributions for mental illness should be examined relative to other social, moral, and religious attributions common in Chinese culture.

    Some basic concepts are exposed for the handling of illnesses in the cultivation of the rice, beginning with the illness definition in the plants, integrating the concept in a system plant-pathogen-environment that in turn would have the subsystem it plants, subsystem pathogen and subsystem environmental conditions. It discusses each one of these subsystems and their influence in the development of the infection. The illnesses of the rice are described taken place by the mushrooms Pyricularia oryzae and Rizoctonia solani and the resistance and receptivity to the pathogens on the part of genetic materials, as well as it influences of the environment and indications are given for their handling. The spotted of the grain of the rice like an illness is described caused by a complex of mushrooms, bacteria and nutritional and climatic factors that cause decrease in the yield and they reduce the quality of the grain and the seed. They are related the pathogens organisms causing the illness, the influence of the environment in their development and instructions are given for their handling

    This article aims at addressing the implications of defining 'comorbidity' within the field of psychiatry. We have looked at the standard definition of comorbidity and then discussed whether this definition can be applied to comorbidities in psychiatry. While comorbidities in physical illness are clearly the coexistence of two independent illnesses, Comorbidities in Mental illness are the result of the polygenic nature of mental illnesses, especially in psychotic illness whether schizophrenia or bipolar disorder. As a consequence, often the comorbidities of psychiatric illness are caused by two conditions which have in common the presence of particular single nucleotide polymorphisms (snps), which regulate the metabolism of neurotransmitters or the presence of neurotrophic factors . Thus inevitably, many such comorbidities are inextricably linked. We discuss the consequences of this form of comorbidity for the description, classification, and risk profile of mental illness.

  10. Mass psychogenic illness after vaccination.

    2003-01-01

    When vaccines are administered to groups, the physical reactions of the recipients may be similar, causing a form of mass reaction, the mechanism for which is the same as that for mass reactions from other causes. These phenomena have been categorised as mass psychogenic illness (MPI), and have been defined as the collective occurrence of a constellation of symptoms suggestive of organic illness but without an identified cause in a group of people with shared beliefs about the cause of the symptom(s). A review of the literature shows that such outbreaks have been reported in differing cultural and environmental settings including developing and industrialised countries, in the work place, on public transport, in schools, and the military. The perceived threats have been against agents such as food poisoning, fire and toxic gases. Whatever the place or perceived threat, the response seems to be similar. The symptoms generally included headache, dizziness, weakness, and loss of consciousness. Once under way, MPIs are not easy to stop. Incidents reported in the literature show that they can quickly gather momentum and can be amplified by the press who disseminate information rapidly, escalating the events. Management of such mass events can be extremely difficult. Should the public health official in charge continue to try and determine the cause, or should this person call off the entire investigation? It is suggested here that once vaccines are identified as a probable cause of the phenomenon, a dismissive approach may actually be harmful. Unless the spokesperson has already earned a high level of trust, the public are not likely to be convinced easily that nothing was wrong with the vaccine until it has been tested. An increased awareness of MPIs on the part of organisers of future mass vaccination campaigns seems appropriate. Immunisation managers should be aware that mass immunisation campaigns could generate such mass reactions. It is therefore essential that

  11. Media portrayal of mental illness and its treatments: what effect does it have on people with mental illness?

    Stuart, Heather

    2006-01-01

    This article reviews dominant media portrayals of mental illness, the mentally ill and mental health interventions, and examines what social, emotional and treatment-related effects these may have. Studies consistently show that both entertainment and news media provide overwhelmingly dramatic and distorted images of mental illness that emphasise dangerousness, criminality and unpredictability. They also model negative reactions to the mentally ill, including fear, rejection, derision and ridicule. The consequences of negative media images for people who have a mental illness are profound. They impair self-esteem, help-seeking behaviours, medication adherence and overall recovery. Mental health advocates blame the media for promoting stigma and discrimination toward people with a mental illness. However, the media may also be an important ally in challenging public prejudices, initiating public debate, and projecting positive, human interest stories about people who live with mental illness. Media lobbying and press liaison should take on a central role for mental health professionals, not only as a way of speaking out for patients who may not be able to speak out for themselves, but as a means of improving public education and awareness. Also, given the consistency of research findings in this field, it may now be time to shift attention away from further cataloguing of media representations of mental illness to the more challenging prospect of how to use the media to improve the life chances and recovery possibilities for the one in four people living with mental disorders.

    This quantitative study sought to compare beliefs about the manifestation, causes and treatment of mental illness and attitudes toward people with mental illness among health professionals from five countries: the United States, Brazil, Ghana, Nigeria, and China. A total of 902 health professionals from the five countries were surveyed using a questionnaire addressing attitudes towards people with mental illness and beliefs about the causes of mental illness. Chi-square and analysis of covariance (ANCOVA) were used to compare age and gender of the samples. Confirmatory factor analysis was employed to confirm the structure and fit of the hypothesized model based on data from a previous study that identified four factors: socializing with people with mental illness (socializing), belief that people with mental illness should have normal roles in society (normalizing), non-belief in supernatural causes (witchcraft or curses), and belief in bio-psycho-social causes of mental illness (bio-psycho-social). Analysis of Covariance was used to compare four factor scores across countries adjusting for differences in age and gender. Scores on all four factors were highest among U.S. professionals. The Chinese sample showed lowest score on socializing and normalizing while the Nigerian and Ghanaian samples were lowest on non-belief in supernatural causes of mental illness. Responses from Brazil fell between those of the U.S. and the other countries. Although based on convenience samples of health professional robust differences in attitudes among health professionals between these five countries appear to reflect underlying socio-cultural differences affecting attitudes of professionals with the greater evidence of stigmatized attitudes in developing countries.

    Full Text Available The crude ethyl acetate extract of the leaves of Cornus macrophylla showed antibacterial activity against Pseudomonas aeruginosa, a leading cause of illness in immunocompromised individuals. Bioactivity-guided separation led to the isolation of kaempferol 3-O-α-L-rhamnopyranoside (afzelin. The structure was determined based on evaluation of its spectroscopic (UV, MS, and NMR data. The minimum inhibitory concentration (MIC of afzelin against Pseudomonas aeruginosa was found to be 31 µg/mL. In addition, the results indicated that a hydroxyl group at C3 of the C-ring of the flavone skeleton and the rhamnose group may act as a negative factor and an enhancing factor, respectively, in the antibacterial activities of afzelin.

    The aim of this qualitative study was to explore the presence, causes and means of addressing individual and systemic stigma and discrimination against people with mental illness in Zambia. This is to facilitate the development of tailor-made antistigma initiatives that are culturally sensitive for Zambia and other low-income African countries. This is the first in-depth study on mental illness stigma in Zambia. Fifty semi-structured interviews and 6 focus group discussions were conducted with key stakeholders drawn from 3 districts in Zambia (Lusaka, Kabwe and Sinazongwe). Transcripts were analyzed using a grounded theory approach. Mental illness stigma and discrimination is pervasive across Zambian society, prevailing within the general community, amongst family members, amid general and mental health care providers, and at the level of government. Such stigma appears to be fuelled by misunderstandings of mental illness aetiology; fears of contagion and the perceived dangerousness of people with mental illness; and associations between HIV/AIDS and mental illness. Strategies suggested for reducing stigma and discrimination in Zambia included education campaigns, the transformation of mental health policy and legislation and expanding the social and economic opportunities of the mentally ill. In Zambia, as in many other low-income African countries, very little attention is devoted to addressing the negative beliefs and behaviours surrounding mental illness, despite the devastating costs that ensue. The results from this study underscore the need for greater commitment from governments and policy-makers in African countries to start prioritizing mental illness stigma as a major public health and development issue.

    2018-04-01

    The diaphragm is the major muscle of inspiration, and its function is critical for optimal respiration. Diaphragmatic failure has long been recognized as a major contributor to death in a variety of systemic neuromuscular disorders. More recently, it is increasingly apparent that diaphragm dysfunction is present in a high percentage of critically ill patients and is associated with increased morbidity and mortality. In these patients, diaphragm weakness is thought to develop from disuse secondary to ventilator-induced diaphragm inactivity and as a consequence of the effects of systemic inflammation, including sepsis. This form of critical illness-acquired diaphragm dysfunction impairs the ability of the respiratory pump to compensate for an increased respiratory workload due to lung injury and fluid overload, leading to sustained respiratory failure and death. This review examines the presentation, causes, consequences, diagnosis, and treatment of disorders that result in acquired diaphragm dysfunction during critical illness.

    Infertility is one of the most serious social problems facing advanced nations. In general, approximate half of all cases of infertility are caused by factors related to the male partner. To date, various treatments have been developed for male infertility and are steadily producing results. However, there is no effective treatment for patients with nonobstructive azoospermia, in which there is an absence of mature sperm in the testes. Although evidence suggests that many patients with male infertility have a genetic predisposition to the condition, the cause has not been elucidated in the vast majority of cases. This paper discusses the environmental factors considered likely to be involved in male infertility and the genes that have been clearly shown to be involved in male infertility in humans, including our recent findings.

    The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.

    To analyse the frequency and characteristics of sports injuries and illnesses incurred during the World Athletics Championships. Prospective recording of newly occurred injuries and illnesses. Twelfth International Association of Athletics Federations World Championships in Athletics 2009 in Berlin, Germany. National team physicians and physiotherapists and 1979 accredited athletes; Local Organising Committee physicians working in the Medical Centres. Incidence and characteristics of newly incurred injuries and illnesses. 236 injury incidents with 262 injured body parts and 269 different injury types were reported, representing an incidence of 135.4 injuries per 1000 registered athletes. Eighty percent affected the lower extremity. Thigh strain (13.8%) was the main diagnosis. Overuse (44.1%) was the predominant cause. Most injuries were incurred during competition (85.9%). About 43.8% of all injury events were expected to result in time-loss. 135 illnesses were reported, signifying an incidence of 68.2 per 1000 registered athletes. Upper respiratory tract infection was the most common condition (30.4%) and infection was the most frequent cause (32.6%). The incidence of injury and illnesses varied substantially among the events. The risk of injury varied with each discipline. Preventive measures should be specific and focused on minimising the potential for overuse. Attention should be paid to ensure adequate rehabilitation of previous injuries. The addition of the illness part to the injury surveillance system proved to be feasible. As most illnesses were caused by infection of the respiratory tract or were environmentally related, preventive interventions should focus on decreasing the risk of transmission, appropriate event scheduling and heat acclimatisation.

    Mental illness is a culturally laden phenomenon, and different cultures have unique ways of constructing mental illness. In this study, conceptions of mental illness were explored among 30 participants of Akan descent in Ghana through individual and group interviews. Participants demonstrated a wide range of knowledge on mental illness indicating that poor self-care, deficits in social functioning, and disordered behaviors are the cardinal features of mental illness. The data revealed that Akan cultural beliefs influenced notions of etiology of mental illness and care of the mentally ill. While participants recognized the role of multiple factors such as genetics, substance abuse, daily hassles (for example, concerns about basic needs such as food, clothing, and shelter), and trauma in the cause of mental illness, the predominant belief was that mental illness is a retributive and/or a spiritual illness. This belief encourages pluralistic health-seeking behaviors: use of hospitals, prayer camps, herbalists, and traditional healers. The implications of these findings for public health education on mental illness, and clinical training and practice are discussed.

    One of the principal problem of Republic of Kazakhstan's pediatricians is onco-hematological diseases. In 1999 hematological illness rate in the Republic makes up 2964.8 per 100,000 of children's population. Side by side with widespread iron-deficit anemia the aplastic anemia and the acute leukemia are often meeting. Annual index of acute leukemia illness number in Kazakhstan makes up 2.6 per 100,000 of children's population. Core of examined children group with acute leukemia presents children living nearby nuclear sites and arrived from Chernobyl and who in consequence (after 3-5 years) fallen ill. It is concluded, that cause of leukemia is sum of unfavourable epidemiologic factors

    Past pandemics arose from low pathogenic avian influenza (LPAI) viruses. In more recent times, highly pathogenic avian influenza (HPAI) H5N1, LPAI H9N2 and both HPAI and LPAI H7 viruses have repeatedly caused zoonotic disease in humans. Such infections did not lead to sustained human-to-human transmission. Experimental infection of human volunteers and seroepidemiological studies suggest that avian influenza viruses of other subtypes may also infect humans. Viruses of the H7 subtype appear to have a predilection to cause conjunctivitis and influenza-like illness (ILI), although HPAI H7N7 virus has also caused fatal respiratory disease. Low pathogenic H9N2 viruses have caused mild ILI and its occurrence may be under-recognised for this reason. In contrast, contemporary HPAI H5N1 viruses are exceptional in their virulence for humans and differ from human seasonal influenza viruses in their pathogenesis. Patients have a primary viral pneumonia progressing to acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome. Over 380 human cases have been confirmed to date, with an overall case fatality of 63%. The zoonotic transmission of avian influenza is a rare occurrence, butthe greater public health concern is the adaptation of such viruses to efficient human transmission, which could lead to a pandemic. A better understanding of the ecology of avian influenza viruses and the biological determinants of transmissibility and pathogenicity in humans is important for pandemic preparedness.

    Depressive symptoms are common in schizophrenia. Previous studies have observed that depressive symptoms are associated with both insight and negative appraisals of illness, suggesting that the way in which the person thinks about their illness may influence the occurrence of depressive responses. In affective disorders, one of the most well-established cognitive processes associated with depressive symptoms is rumination, a pattern of perseverative, self-focused negative thinking. This study examined whether rumination focused on mental illness was predictive of depressive symptoms during the subacute phase of schizophrenia. Forty participants with a diagnosis of schizophrenia and in a stable phase of illness completed measures of rumination, depressive symptoms, awareness of illness, and positive and negative symptoms. Depressive symptoms were correlated with rumination, including when controlling for positive and negative symptoms. The content of rumination frequently focused on mental illness and its causes and consequences, in particular social disability and disadvantage. Depressive symptoms were predicted by awareness of the social consequences of mental illness, an effect that was mediated by rumination. Results suggest that a process of perseveratively dwelling upon mental illness and its social consequences may be a factor contributing to depressive symptoms in people with chronic schizophrenia.

  8. 'Old' and 'new' institutions for persons with mental illness: treatment, punishment or preventive confinement?

    2008-09-01

    Despite countless promises for a better life by national commissions, governments and the international community, there has evolved a vicious cycle of neglect, abandonment, indignity, cruel and inhuman treatment, and punishment of persons with mental illness. This shameful history of benign, and sometimes malignant, neglect of persons with mental illness is well understood, with the deep stigma and unredressed discrimination, the deplorable living conditions, and the physical and social barriers preventing their integration and full participation in society. The maltreatment of this vulnerable population has been reinforced by the hurtful stereotypes of incompetency and dangerousness. The belief that persons with mental illness are uniformly dangerous is an equally harmful myth. It provides policy makers with an ostensible justification to exercise control over persons with mental illness, even if they have not committed a violent offence. However, research demonstrates that the class of persons with most mental illnesses is no more dangerous than other populations, and that the vast majority of violence is committed by persons without mental illness. This article will show how this vulnerable population has been unconscionably treated. First, the gross violations of human rights that have occurred, and continue to occur, in 'old' psychiatric institutions will be examined. The deinstitutionalization movement, however, resulted in new places of confinement for this population, such as jails, prisons and homeless shelters. The second part of this paper will explore the new realities of criminal confinement of persons with mental illness. As we will see, incarceration of this vulnerable population in the criminal justice system has caused enormous suffering. If Dostoyevsky was correct that the 'degree of civilization... can be judged by entering its prisons', then by that measure, we are a deeply uncivilized society.

    Understanding and perceptions about mental illness vary among individuals based on their experience with the illness or their contact with the people affected by it. These may be further influenced by the individuals' sociocultural background. This study aimed to understand the differences in the beliefs about, understanding of, and explanations for mental illness between different population groups of Jharkhand, India. During July 2014 to February 2016, we recruited the following 3 groups of individuals aged between 18 and 60 years: individuals with mental illness (group 1, n = 240), relatives of individuals with mental illness (group 2, n = 240), and the general public (group 3, n = 240). Qualitative and quantitative findings were combined in this study, and participants were asked about their beliefs about, understanding of, and explanations about mental illness. Individuals with mental illness and their relatives shared similar beliefs whereas the general public held a different opinion in various domains. There were significant differences among all groups in their understanding of various aspects of mental illnesses including the definition, causes, signs and symptoms, treatment, and outcomes. Individuals' perception towards different aspects of mental illness varies, despite they are sharing the same sociocultural milieu. Differences in beliefs, understanding, and explanations may lead to conflicts in treatment goals and expectations, and hamper the intervention strategies that promote mental health and patient care. Focused strategies to develop uniformity in beliefs and explanations about various aspects of mental illness may help to develop collaboration with different community groups that may in turn help in developing effective interventions and treatment.

    Full Text Available Abstract Background Infections caused by human rhinoviruses (HRVs are important triggers of wheezing in young children. Wheezy illness has increasingly been recognised as an important cause of morbidity in African children, but there is little information on the contribution of HRV to this. The aim of this study was to determine the role of HRV as a cause of acute wheezing in South African children. Methods Two hundred and twenty children presenting consecutively at a tertiary children's hospital with a wheezing illness from May 2004 to November 2005 were prospectively enrolled. A nasal swab was taken and reverse transcription PCR used to screen the samples for HRV. The presence of human metapneumovirus, human bocavirus and human coronavirus-NL63 was assessed in all samples using PCR-based assays. A general shell vial culture using a pool of monoclonal antibodies was used to detect other common respiratory viruses on 26% of samples. Phylogenetic analysis to determine circulating HRV species was performed on a portion of HRV-positive samples. Categorical characteristics were analysed using Fisher's Exact test. Results HRV was detected in 128 (58.2% of children, most (72% of whom were under 2 years of age. Presenting symptoms between the HRV-positive and negative groups were similar. Most illness was managed with ambulatory therapy, but 45 (35% were hospitalized for treatment and 3 (2% were admitted to intensive care. There were no in-hospital deaths. All 3 species of HRV were detected with HRV-C being the most common (52% followed by HRV-A (37% and HRV-B (11%. Infection with other respiratory viruses occurred in 20/128 (16% of HRV-positive children and in 26/92 (28% of HRV-negative samples. Conclusion HRV may be the commonest viral infection in young South African children with acute wheezing. Infection is associated with mild or moderate clinical disease.

    1999-04-01

    There is a dearth of studies examining how dangerousness is constructed in media depictions of mentally ill individuals who are frequently portrayed as acting violently. The aim of the present study was to identify the contribution of diverse technical, semiotic and discursive resources utilised in portraying a character with a mental illness in a prime-time drama as dangerous. Discourse analytic techniques, involving systematic, repeated, critical viewings, were applied to a single program drawn from a sample of prime-time television drama episodes touching on mental illness. Nine devices (appearance, music and sound effects, lighting, language, intercutting, jump-cutting, point of view shots, horror conventions and intertextuality) were identified as contributing to the signified dangerousness of person receiving care in the community for a mental illness. These techniques combine in signifying mental illness and a person suffering from it as dangerous. The findings suggest that mental health professionals working to reduce the stigma of mental illness need to have a reasonably sophisticated understanding of the practices and priorities of television production if they are to collaborate effectively with producers to create dramas that convey more human and sympathetic understandings of mental illness or to combat the negative effects of such portrayals.

  13. The 2008 M7.9 Wenchuan earthquake - a human-caused event

    2013-12-01

    A catalog of global human-caused earthquakes shows statistical evidence that the triggering of earthquakes by large-scale geoengineering activities depends on geological and tectonic constrains (in Klose 2013). Such geoengineering activities also include the filling of water reservoirs. This presentation illuminates mechanical and statistical aspects of the 2008 M7.9 Wenchuan earthquake in light of the hypothesis of being NOT human-caused. However, available data suggest that the Wenchuan earthquake was triggered by the filling of the Zipungpu water reservoir 30 months prior to the mainshock. The reservoir spatially extended parallel and near to the main Beichuan fault zone in a highly stressed reverse fault regime. It is mechanically evident that reverse faults tend to be very trigger-sensitive due to mass shifts (static loads) that occur on the surface of the Earth's crust. These circumstances made a triggering of a seismic event of this magnitude at this location possible (in Klose 2008, 2012). The data show that the Wenchuan earthquake is not an outlier. From a statistical view point, the earthquake falls into the upper range of the family of reverse fault earthquakes that were caused by humans worldwide.

    2012-01-01

    Full Text Available Murine typhus is a widely distributed flea-borne infection caused by Rickettsia typhi. Symptoms of murine typhus are nonspecific and mimic a variety of other infectious diseases. We herein report a case of murine typhus in an area where the broad use of DDT in the mid-20th century has now made it a rare disease. The patient described presented with headache, fever, and a faint macular rash. Initial laboratory studies revealed a slight transaminase elevation. Further questioning revealed exposure to opossums, prompting the consideration of murine typhus as a diagnosis. Although typhus group antibodies were not present during the patient’s acute illness, empiric therapy with doxycycline was initiated, and the patient defervesced. One month after convalescence, the patient returned to clinic with serum that contained typhus group antibodies with an IgG titer of 1 : 1024. Murine typhus is an important consideration during the workup of a patient with a nonspecific febrile illness. Exposure to reservoir hosts and the flea vector place humans at risk for this disease. Clinician recognition of this entity is required for diagnosis and effective therapy.

  15. Achieving health equity: from root causes to fair outcomes.

    Health is a universal human aspiration and a basic human need. The development of society, rich or poor, can be judged by the quality of its population's health, how fairly health is distributed across the social spectrum, and the degree of protection provided from disadvantage due to ill-health. Health equity is central to this premise and to the work of the Commission on Social Determinants of Health. Strengthening health equity--globally and within countries--means going beyond contemporary concentration on the immediate causes of disease. More than any other global health endeavour, the Commission focuses on the "causes of the causes"--the fundamental structures of social hierarchy and the socially determined conditions these create in which people grow, live, work, and age. The time for action is now, not just because better health makes economic sense, but because it is right and just. The outcry against inequity has been intensifying for many years from country to country around the world. These cries are forming a global movement. The Commission on Social Determinants of Health places action to ensure fair health at the head and the heart of that movement.

    INTRODUCTION: Understanding the spectrum and frequencies of Epstein-Barr virus (EBV) complications and markers of illness severity in immunocompetent patients with primary EBV infection will inform management of patients with EBV-related illnesses. OBJECTIVES: To determine the clinical and laboratory correlates of illness severity among infants, children and youth with infectious mononucleosis (IM). METHODS: Study subjects with confirmed IM were prospectively enrolled. Illness severity was assessed at baseline and at six weeks using a scoring tool. Peripheral blood viral loads served as a measure of viral burden. RESULTS: Among 32 children and young adults with IM, the median age was 16 years (range two to 24 years). The predominant clinical findings were lymphadenopathy (23 of 32 [72%]), pharyngitis (16 of 32 [50%]), fever (nine of 32 [28%]) and splenomegaly (six of 32 [19%]). With respect to symptoms or signs that persisted to at least six weeks after illness onset, the predominant complaint was lymphadenopathy in 35% of subjects available for reassessment. Deranged liver function tests were present at presentation in up to 44% of subjects. Patients with the highest viral loads at presentation had significantly higher illness severity scores associated with fatigue (P=0.02). Other than the scores associated with fatigue, viral load values were not significantly correlated with the illness severity scores at baseline and at six weeks. CONCLUSION: In IM, viral loads are not necessarily correlated with illness severity, with the exception of fatigue. EBV-related hepatitis is common in IM, confirming the status of this virus as a relatively common cause of transient hepatitis in children and youth. This entity is not necessarily a marker of disease severity. PMID:25371691

    Objective Leprosy has rarely been the subject of health psychology research despite its substantial impact. Our aim was to explore illness perceptions in patients and their health care providers in Surinam. The Common Sense Model (CSM) was the guiding theoretical model. Design Patients with biomedically cured leprosy and their health care providers completed the B-IPQ and took part in semi-structured interviews. The literature on illness perceptions in patients with leprosy was reviewed. Main outcome measures Patients' B-IPQ scores were compared with samples of patients with other (chronic) illnesses, and with health care providers completing the questionnaire as if they were visibly disfigured patients. Quotations from the semi-structured interviews were used to contextualise the illness perceptions. Results Patients' B-IPQ scores reflected the chronic nature of leprosy and were comparable with those with other chronic illnesses. Health care providers perceived leprosy to have a greater negative impact than did the patients. Perceived understanding of causes differed considerably between patients and health care providers. Conclusion Leprosy continues to be experienced as an illness with major psychological and social consequences such as stigmatisation, even after biomedical cure. Interventions that target patients, health care providers, and society at large may help reduce perceived shame and stigma. The CSM is a helpful theoretical model in studying this population.

This disease is often found in tropical countries, particularly in the community with low socio-economic level. From many flies causing myiasis, Chrysomya bezziana is medically the most important agent due to its obligate parasite property and causing economies losses . Some myiasis cases on humans and animals in Indonesia are caused by C. bezziana larvae infestation or mixed infestation with Sarcophaga sp . Sulawesi, East Sumba, Lombok, Sumbawa, Papua and Java islands were reported as myiasis endemic areas . Myiasis cases on animals occurred after parturition (vulval myiasis then is followed by umbilical myiasis on their calf or traumatic wounds, while myiasis on humans are caused by untreated fresh wounds or chronic wounds such as leprosy, diabetes, etc . Besides, nature holes like nose, eyes, ears or mouth are also reported as entry port for those larvae . Clinical signs of myiasis are various and non-specific depends on location of infested part of body, i.e . fever, inflammation, pruritus, headache, vertigo, swelling and hipereosinophilia . There would be serious conditions with secondary infection by bacteria . Myiasis treatment on animals is simpler than humans . Surgical operation is often carried out on infested human part of bodies . Insecticides were used to treat animal myiasis but had raised resistant . Myiasis treatment on humans may be done locally or systemically . Antibiotic broad spectrum or which is suitable with culture and resistance status of bacteria were given for systemic treatment . Chloroform and turpentine with ratio 1 : 4 were used for local treatment . Some of essential oils have also been tested in laboratory as an alternative medicine for both humans and animals myiasis .

    Many people with mental illness do not seek professional help. Beliefs about the causes of their current health problem seem relevant for initiating treatment. Our aim was to find out to what extent the perceived causes of current untreated mental health problems determine whether a person considers herself/himself as having a mental illness, perceives need for professional help and plans to seek help in the near future. In a cross-sectional study, we examined 207 untreated persons with a depressive syndrome, all fulfilling criteria for a current mental illness as confirmed with a structured diagnostic interview (Mini International Neuropsychiatric Interview). The sample was recruited in the community using adverts, flyers and social media. We elicited causal explanations for the present problem, depression literacy, self-identification as having a mental illness, perceived need for professional help, help-seeking intentions, severity of depressive symptoms (Patient Health Questionnaire - Depression), and whether respondents had previously sought mental healthcare. Most participants fulfilled diagnostic criteria for a mood disorder (n = 181, 87.4%) and/or neurotic, stress-related and somatoform disorders (n = 120, 58.0%) according to the ICD-10. N = 94 (45.4%) participants had never received mental health treatment previously. Exploratory factor analysis of a list of 25 different causal explanations resulted in five factors: biomedical causes, person-related causes, childhood trauma, current stress and unhealthy behaviour. Attributing the present problem to biomedical causes, person-related causes, childhood trauma and stress were all associated with stronger self-identification as having a mental illness. In persons who had never received mental health treatment previously, attribution to biomedical causes was related to greater perceived need and stronger help-seeking intentions. In those with treatment experience, lower attribution to person-related causes and

Chronic inflammation in peripheral tissues is indicated by the increase of inflammatory marker like cytokine IL-6, TNF-α, and IL-1β. Pro-inflammatory cytokine in peripheral tissues can reach brain tissues and activate microglia and it causes neuroinflammation. Psychological stress may led peripheral and central inflammation. Activated microglia will produce pro-inflammatory cytokine, ROS, RNS, and tryptophan catabolizes. This neuroinflammation can promote metabolism changes of any neurotransmitter, such as serotonin, dopamine, and glutamate that will influence neurocircuit in the brain including basal ganglia and anterior cingulated cortex. It leads to mental illness. Exercise give contribution to reduce tissue inflammation. When muscle is contracting in an exercise, muscle will produce the secretion of cytokine like IL-6, IL-1ra, and IL-10. It will react as anti-inflammation and influence macrophage, T cell, monosit, protein Toll-Like Receptor (TLR), and then reduce neuroinflammation, characterised by the decrease of pro-inflammatory cytokine and prevent the activation of microglia in the brain. The objective of the present study is to review scientific articles in the literature related to the contribution of exercise to prevent and ease mental illness.

    Full Text Available Abstract Background Early recognition of the signs and symptoms of mental health disorders is important because early intervention is critical to restoring the mental as well as the physical and the social health of an individual. This study sought to investigate patterns of treatment seeking behavior and associated factors for mental illness. Methods A quantitative, institution-based cross sectional study was conducted among 384 psychiatric patients at Jimma University Specialized Hospital (JUSH located in Jimma, Ethiopia from March to April 2010. Data was collected using a pretested WHO encounter format by trained psychiatric nurses. Data was analyzed using SPSS V.16. Result Major depression disorder 186 (48.4%, schizophrenia 55 (14.3% and other psychotic disorders 47 (12.2% were the most common diagnoses given to the respondents. The median duration of symptoms of mental illness before contact to modern mental health service was 52.1 weeks. The main sources of information for the help sought by the patients were found to be family 126 (32.8% and other patients 75 (19.5%. Over a third of the patients 135 (35.2%, came directly to JUSH. Half of the patients sought traditional treatment from either a religious healer 116 (30.2% or an herbalist 77 (20.1% before they came to the hospital. The most common explanations given for the cause of the mental illness were spiritual possession 198 (51.6% and evil eye 61 (15.9%, whereas 73 (19.0% of the respondents said they did not know the cause of mental illnesses. Nearly all of the respondents 379 (98.7% believed that mental illness can be cured with modern treatment. Individuals who presented with abdominal pain and headache were more likely to seek care earlier. Being in the age group 31-40 years had significant statistical association with delayed treatment seeking behavior. Conclusions There is significant delay in modern psychiatric treatment seeking in the majority of the cases. Traditional healers

    The presence or development of malnutrition during critical illness has been unequivocally associated with increased morbidity and mortality in people. Recognition that malnutrition may similarly affect veterinary patients emphasizes the need to properly address the nutritional requirements of hospitalized dogs and cats. Because of a lack in veterinary studies evaluating the nutritional requirements of critically ill small animals, current recommendations for nutritional support of veterinary patients are based largely on sound clinical judgment and the best information available, including data from experimental animal models and human studies. This, however, should not discourage the veterinary practitioner from implementing nutritional support in critically ill patients. Similar to many supportive measures of critically ill patients, nutritional interventions can have a significant impact on patient morbidity and may even improve survival. The first step of nutritional support is to identify patients most likely to benefit from nutritional intervention. Careful assessment of the patient and appraisal of its nutritional needs provide the basis for a nutritional plan, which includes choosing the optimal route of nutritional support, determining the number of calories to provide, and determining the composition of the diet. Ultimately, the success of the nutritional management of critically ill dogs and cats will depend on close monitoring and frequent reassessment.

    Background. The objectives of the study were to explore the knowledge and attitudes of Pakistani university students toward mental illnesses. People with mental illnesses are challenged not only by their symptoms but also by the prejudices associated with their illness. Acknowledging the stigma of mental illness should be the first essential step toward devising an appropriate treatment plan. Methods. A cross-sectional survey was conducted at the University of Punjab, Lahore, CMH Lahore Medical and Dental College, Lahore, and University of Sargodha, Sub-campus Lahore, from February to May 2014. The self-administered questionnaire consisted of three sections: demographics, general knowledge of psychiatric illnesses, and Community Attitudes towards Mental Illnesses (CAMI) Scale. The questionnaire was distributed to 650 participants enrolled in different disciplines (Social Sciences, Medicine and Formal Sciences). Results. Response rate was 81% (527/650 respondents). Mean age was 20.98 years. Most of the students (331, 62.8%) had an urban background and studied Social Sciences (238, 45.2%). Four hundred and eighteen respondents (79.3%) considered religion very important and most respondents considered psychiatrists (334, 63.4%) and spiritual leaders (72, 13.7%) to be best able to treat mental illnesses. One hundred and sixty nine respondents (32.1%) considered black magic to be a cause of mental illness. Only 215 (41%) respondents had ever read an article on mental illnesses. Multiple regression analysis revealed study discipline, exposure, perceived causes of mental illnesses and superstitions to be significantly associated with attitudes towards mental illnesses (p supernatural explanations for mental illnesses but only a few believed that spiritual leaders can play a role in treatment.

    Cultures all over the world have evolved illness representations that can accommodate not only new diseases, but also new epistemologies for explaining disease. This paper examines illness representations in Sub-Saharan Africa, and how these have responded to the emergence of AIDS. Indigenous views of illness (particularly STDs) exhibit coherent structure, in which causation, prevention and treatment relate to one another in functional ways. As an STD, an epidemic, and a disease which leads to premature death, AIDS lends itself readily to accommodation into established indigenous representations of illness. Even biomedical views of causation can be readily incorporated into traditional views of how illnesses are caused. However, biomedical and traditional views concerning prevention appear to be in direct conflict with one another, with potentially hazardous consequences. Research exploring the extent to which indigenous beliefs may be influencing people's decisions about safe sex could offer useful insights for AIDS prevention programs.

    2013-06-01

    The aim of this study is investigate whether the cross-cultural value paradigm 'individualism-collectivism' is a useful explanatory model for mental illness stigma on a cultural level. Using snowball sampling, a quantitative questionnaire survey of 305 individuals from four UK-based cultural groups (white-English, American, Greek/Greek Cypriot, and Chinese) was carried out. The questionnaire included the 'Community Attitudes to Mental Illness scale' and the 'vertical-horizontal individualism-collectivism scale'. The results revealed that the more stigmatizing a culture's mental illness attitudes are, the more likely collectivism effectively explains these attitudes. In contrast, the more positive a culture's mental illness attitudes, the more likely individualism effectively explains attitudes. We conclude that a consideration of the individualism-collectivism paradigm should be included in any future research aiming to provide a holistic understanding of the causes of mental illness stigma, particularly when the cultures stigmatization levels are particularly high or low.

    A 38 year old man with history of obstructive sleep apnea and polycythaemia presented with hypercapnic respiratory failure that required intubation. He developed fever with infiltrates on chest radiography that required empiric antifungal therapy with fluconazole along with broad spectrum antibiotics. He developed acute adrenal insufficiency that recovered after fluconazole was stopped. It is believed that this complication of adrenal suppression attributable to fluconazole is underrecognised and it may be prudent to monitor all critically ill patients who are given fluconazole for this complication.

    Mental illness is a disease that affects millions of people every year. It not only causes stress to the mentally ill patients, but also for the family members who provide them the care. The family caregivers, therefore need some form of coping strategies in dealing with their mentally ill family members. This qualitative study aims at identifying and analysing the coping strategies adopted by the family caregivers in dealing with their mentally ill family members. A total of 15 family caregivers from the state of Kedah, Malaysia participated in the face-to-face semi structured interview. The study findings identified an array of coping strategies used by the family caregivers, including religious coping, emotional coping, acceptance, becoming engaged in leisure activities, and the use of traditional healing to help them cope with their mentally ill members. Suggestions and conclusions: Study suggests that the family caregivers should engage themselves in social support groups to learn about and obtain the positive coping strategies used by other caregivers who have similar experiences in caring for the mentally ill. Study also suggests that they should get appropriate training from the mental health professionals in order to enhance the caregivers' coping skills.

    Alcohol-based hand sanitizer (HS) kills most organisms that cause acute illness, an important cause of lost duty time among aviation personnel. This preliminary study observed the impact on the acute illness rate when HS was made readily accessible to pilots. Wall-mounted HS dispensers were placed in two fighter squadron operations buildings during November 2005 and various media were used to alert all base personnel to the importance of hand hygiene and cough hygiene. Data were obtained for two groups of personnel on the same base: 1) pilots who worked in the two HS-equipped buildings (Squadron) (n = 56); and 2) pilots and air traffic controllers who worked at other locations (Non-Squadron) (n = 61). The incidence of acute illness and the cumulative number of duty days lost was determined in each group for the winters of 2004-05 (no HS) and 2005-06 (HS available). For the Squadron group, the acute illness rates were 2.4% in 2004-5 (210 duty days lost) (no HS) compared with 0.9% in 2005-6 (78 duty days lost) when HS was provided. No year-to-year difference was apparent for the Non-Squadron group, where the illness rates were 2.4% in 2004-5 (229 duty days lost) and 2.3% in 2005-6 (221 duty days lost). Making HS readily available at locations frequented by pilots together with educating them regarding hand hygiene may reduce the occurrence of acute illness and number of duty days lost.

  14. Unstable mutations: cause of some neurological hereditary diseases

    1999-01-01

    Unstable mutations or amplification of triplets constitute a kind of genetic alteration discovered during the last decade. They had been found inside or near genes important for the normal neurological function of the human being. In some cases, the presence of the amplification causes the inactivation of the gene or the synthesis of a new product which functions different from the original protein. Some common characteristics of diseases caused by the amplification of triplets are that it affects the nervous system and are degenerative in nature. The expression of the manifestations varies according to age. Most of them show genetic anticipation in which the severity of the manifestations increases with each generation and appear at an earlier age. In most cases, the severity of the symptoms is correlated positively to the size of the amplification. The diagnosis of an affected individual in a family may indicate the presence of an altered gene in other relatives. These relatives may not present evident signs of the illness either because it is of late onset or because they carry premutations. The molecular diagnosis of these mutations is important to estimate the risk of developing the disease and/or of transmitting the illness to the descendants and to eliminate the fears of healthy relatives who have inherited normal copies of the gene.

    1996-01-01

    Cancer, a major killer throughout human history, changed its grasp as humankind advanced industrially and technologically. Although the risk of a few types of cancer has declined dramatically in developed countries in this century, the incidence of the most significant forms of the disease has increased. Cancers of the lung, breast, prostate and colon and rectum have all become more frequent in countries where risk factors such as cigarette smoking, unhealthful dietary habits and exposure to dangerous chemicals at work or in the environment are now more common. As industrialization has proliferated, so, too, have the suspected causes of cancer. In recent years, news accounts have been full of warnings about all manner of modern conveniences, from pharmaceuticals to cellular telephones. Meanwhile the pace of technological advance makes it more vital than ever to single out definitive causes of cancer from an ever expanding array of possibilities. For this daunting task, researchers rely heavily on epidemiology. Epidemiologists identify factors that are common to cancer victims’ history and way of life and evaluate them in the context of current biological understanding. Ultimately, the evidence may persuade researchers that one or more of these factors or characteristics “cause” the disease— that is to say, exposure to them significantly increases the odds of the illness developing

    Florence Nightingale's Crimean fever and chronic illness have intrigued historians for more than a century and a half. The purpose of this article is threefold: (a) to discuss the facts that point to the cause of Nightingale's Crimean fever as brucellosis, (b) to show that her debilitating illness for 32 years (1855-1887) was compatible with the specific form of chronic brucellosis, and (c) to present new evidence that she was still having severe symptoms in December 1887, when it was previously felt that she had no severe symptoms after 1870.

    2015-01-01

    During or very soon after the 1990-1991 Persian Gulf War, veterans of the conflict began to report symptoms of illness. Common complaints included combinations of cognitive difficulties, fatigue, myalgia, rashes, dyspnea, insomnia, gastrointestinal symptoms and sensitivity to odors. Gradually in the USA, and later in the UK, France, Canada, Denmark and Australia, governments implemented medical assessment programs and epidemiologic studies to determine the scope of what was popularly referred to as "the Gulf War syndrome". Attention was drawn to numerous potentially toxic deployment-related exposures that appeared to vary by country of deployment, by location within the theater, by unit, and by personal job types. Identifying a single toxicant cause was considered unlikely and it was recognized that outcomes were influenced by genetic variability in xenobiotic metabolism. Derived from primary papers and key reports by the Research Advisory Committee on Gulf War Veterans' Illnesses and the Institute of Medicine, a brief overview is presented of war related events, symptoms and diagnostic criteria for Gulf War illness (GWV), some international differences, the various war-related exposures and key epidemiologic studies. Possible exposure interactions and pathophysiologic mechanisms are discussed. Exposures to pyridostigmine bromide, pesticides, sarin and mustard gas or combinations thereof were most associated with GWI, especially in some genotype subgroups. The resultant oxidant stress and background exposome must be assumed to have played a role. Gulf War (GW) exposures and their potential toxic effects should be considered in the context of the human genome, the human exposome and resultant oxidant stress to better characterize this unique environmentally-linked illness and, ultimately, provide a rationale for more effective interventions and future prevention efforts.

    Injury and death from wildlife attacks often result in people feeling violent resentment and hostility against the wildlife involved and, therefore, may undermine public support for conservation. Although Nepal, with rich biodiversity, is doing well in its conservation efforts, human-wildlife conflicts have been a major challenge in recent years. The lack of detailed information on the spatial and temporal patterns of human-wildlife conflicts at the national level impedes the development of effective conflict mitigation plans. We examined patterns of human injury and death caused by large mammals using data from attack events and their spatiotemporal dimensions collected from a national survey of data available in Nepal over five years (2010-2014). Data were analyzed using logistic regression and chi-square or Fisher's exact tests. The results show that Asiatic elephants and common leopards are most commonly involved in attacks on people in terms of attack frequency and fatalities. Although one-horned rhinoceros and bears had a higher frequency of attacks than Bengal tigers, tigers caused more fatalities than each of these two species. Attacks by elephants peaked in winter and most frequently occurred outside protected areas in human settlements. Leopard attacks occurred almost entirely outside protected areas, and a significantly greater number of attacks occurred in human settlements. Attacks by one-horned rhinoceros and tigers were higher in the winter, mainly in forests inside protected areas; similarly, attacks by bears occurred mostly within protected areas. We found that human settlements are increasingly becoming conflict hotspots, with burgeoning incidents involving elephants and leopards. We conclude that species-specific conservation strategies are urgently needed, particularly for leopards and elephants. The implications of our findings for minimizing conflicts and conserving these imperiled species are discussed.

    Full Text Available Nowadays, paralel to prolonging life time, illness experience can change life of everyone who takes care of the individual directly or indirectly. Prolonging of this time for patient, simultaneously causes prolonging of the time for the care and treatment providers and them to be with the patient more during illness and suffering process. Caring for chronically ill individuals by getting aware of that they won't be able to recover completely, causes them to experience various problems called compassion fatigue. Compasion fatigue is described as the natural feeling and behaviour arising from knowing the traumatizing events which a significant other has experienced; as the stress arising from helping or wanting to help a traumatized individual. The aim of this review is to describe compassion fatigue, explain the concepts with which it is related, and by this way to increase the awareness of professionals who work in helping professions.

    2016-12-30

    The present study applied the common sense model to understand the underlying mechanism of how cognitive and emotional representations of mental illness among people in recovery of mental illness would impact their endorsement of self-stigma, and how that would, in turn, affect clinical and personal recovery. A cross-sectional survey was administered to 376 people in recovery. Participants were recruited from seven public specialty outpatient clinics and substance abuse assessment clinics across various districts in Hong Kong. They were asked to report their perception towards their mental illness, self-stigma, symptom severity, and personal recovery. The results of structural equation modeling partially supported the hypothesized mediation model indicating that controllability, consequences, and emotional concern of mental illness, but not cause, timeline, and identity, were associated with self-stigma, which was subsequently negatively associated with clinical and personal recovery. The present study demonstrated the mediating role of self-stigma in the relationship between individuals' illness representations towards their mental illness and their recovery. Illness management programs aimed at addressing the maladaptive mental illness-related beliefs and emotions are recommended. Implications on developing self-directed and empowering mental health services are discussed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Background Public understanding about mental illnesses and attitudes towards people with mental illness (PWMI) play a paramount role in the prevention and treatment of mental illness and the rehabilitation of PWMI. The aim of this study was to measure public stigma against PWMI and the factors associated with stigma in the Gilgel Gibe Field Research Center (GGFRC) in Southwest Ethiopia. Methods This community-based, cross-sectional study was conducted from June to August 2012 among 845 randomly selected respondents by using the Community Attitudes towards the Mentally Ill (CAMI) scale, an interviewer-administered questionnaire. Data was entered with EPI-DATA and then exported to STATA for analysis. Simple descriptive and linear regression analyses were performed to identify predictors of stigma against PWMI. Results Of the total of 845 respondents, 68.17% were from rural districts. The mean stigma score was 2.62 on a 5-point score. The majority of the respondents (75.27%) believed that mental illness can be cured. Stress, poverty, and rumination were the most often perceived causes of mental illness. Rural residents had significantly higher stigma scores (std. β = 0.61, Psupernatural causes (std. β = −0.09, P<0.01) and perceived psychosocial and biological causes (std. β = −0.14, P<0.001) had significantly lower stigma levels. Conclusions The study found a more undermining but less avoidant attitude towards PWMI. Rural residents showed higher levels of stigma. Stigma against PWMI was lower in people with an explanatory concept about the causes of mental illness and a higher level of education. Information, education, and communication about the causes, signs, and nature of mental illnesses would help to reduce stigma. PMID:24324756

    Low capacity factor, in any NPP, is a result of high occurrence rates of significant events. A substantial portion of such occurrences is caused by inappropriate action due to inadequate human performance. To improve human performance we need first to do its evaluation. This paper describes the essential elements of the first basic step in that context: diagnosis or identification of the fundamental causes of human performance problems in Indian NPPs. (author)

    Four assumptions frequently arise in the aftermath of mass shootings in the United States: (1) that mental illness causes gun violence, (2) that psychiatric diagnosis can predict gun crime, (3) that shootings represent the deranged acts of mentally ill loners, and (4) that gun control "won't prevent" another Newtown (Connecticut school mass shooting). Each of these statements is certainly true in particular instances. Yet, as we show, notions of mental illness that emerge in relation to mass shootings frequently reflect larger cultural stereotypes and anxieties about matters such as race/ethnicity, social class, and politics. These issues become obscured when mass shootings come to stand in for all gun crime, and when "mentally ill" ceases to be a medical designation and becomes a sign of violent threat.

    The frequency of decompression illness was high among the extinct marine "reptiles" and very low among the marine mammals. Signs of decompression illness are still found among turtles but whales and seals are unaffected. In humans, the risk of decompression illness is five times increased in individuals with Patent Foramen Ovale; this condition allows blood shunting from the venous circuit to the systemic circuit. This right-left shunt is characteristic of the "reptile" heart, and it is suggested that this could contribute to the high frequency of decompression illness in the extinct reptiles.

    To report a case of Chryseobacterium indologenes ventilator-associated pneumonia (VAP) in a critically ill trauma patient. This report describes a 66-year-old critically ill trauma patient who developed VAP, which was caused by C indologenes. The patient was injured in a riding lawn mower accident that trapped him underwater in a pond. The patient required surgery for intra-abdominal injuries and was mechanically ventilated in the trauma intensive care unit. On hospital day 5, the patient developed signs and symptoms of VAP. A diagnosis of C indologenes VAP was confirmed based on a quantitative culture from a bronchoscopic bronchoalveolar lavage. The patient's infection was successfully treated with moxifloxacin for 2 days followed by cefepime for 7 days. Formally known as Flavobacterium indologenes, C indologenes is a Gram-negative bacillus normally found in plants, soil, foodstuffs, and fresh and marine water sources. Recently, worldwide reports of C indologenes infections in humans have been increasing, though reports from the United States are still rare. Bacteremia and pneumonia are the most commonly reported infections, and most patients are immunocompromised. The current case differs from most previous reports because this patient was in the United States and did not have any traditional immunocompromised states (eg, transplant, cancer, HIV/AIDS, or corticosteroid use). This case report demonstrates that C indologenes can cause VAP in a trauma ICU patient.

    Public attitudes toward mental illness in two widely disparate cultures, Canada and Cameroon, were compared using an experimental version of a survey instrument, the Public Opinion Survey of Human Attributes-Mental Illness or POSHA-MI(e). 120 respondents rated POSHA-MI(e) items relating to mental illness on 1-9 equal appearing interval scales: 30 in English and 30 in French in both Cameroon and Canada. Additionally, 30 matched, monolingual English, American respondents were included as a comparison group. In Canada (and in the USA), attitudes were generally more positive and less socially stigmatizing toward mental illness than in Cameroon. Differences between countries were much larger than differences between language groups. Consistent with other research, beliefs and reactions of the public regarding mental illness reflect stigma, especially in Cameroon. Cultural influences on these public attitudes are more likely important than language influences. Results of this field test of the POSHA-MI(e), documenting differences in public attitudes toward mental illness in two divergent cultures, support its further development.

    The authors evaluated whether a psychiatric clerkship reduces stigmatized attitudes towards people with mental illness among medical students. A 56-item questionnaire was used to assess the attitudes of medical students towards patients with mental illness and their beliefs about its causes before and after their participation in their psychiatric clerkship at a major medical school in Rio de Janeiro. Exploratory factor analysis identified four factors, reflecting "social acceptance of people with mental illness," "normalizing roles for people with mental illness in society," "non-belief in supernatural causes for mental illness," and "belief in bio-psychosocial causes for mental illness." Analysis of variance was used to evaluate changes in these factors before and after the clerkship. One significant difference was identified with a higher score on the factor representing social acceptance after as compared to before the clerkship (p = 0.0074). No significant differences were observed on the other factors. Participation in a psychiatric clerkship was associated with greater social acceptance but not with improvement on other attitudinal factors. This may reflect ceiling effects in responses before the clerkship concerning supernatural and bio-psychosocial beliefs about causes of mental illness that left little room for change.

    This preliminary study examined the differences between what was taught during a formal medical education and medical students' and psychiatry residents' conceptions of notions regarding the causes and determinants of mental illness. The authors surveyed 74 medical students and 11 residents via convenience sampling. The survey contained 18 statements which were rated twice based on truthfulness in terms of a participant's formal education and conception, respectively. Descriptive statistics and a Wilcoxon signed rank test determined differences between education and conception. Results showed that students were less likely to perceive a neurotransmitter imbalance to cause mental illness, as opposed to what was emphasized during a formal medical education. Students and residents also understood the importance of factors such as systemic racism and socioeconomic status in the development of mental illness, which were factors that did not receive heavy emphasis during medical education. Furthermore, students and residents believed that not only did mental illnesses have nonuniform pathologies, but that the Diagnostic and Statistical Manual of Mental Disorders also had the propensity to sometimes arbitrarily categorize individuals with potentially negative consequences. If these notions are therefore part of students' and residents' conceptions, as well as documented in the literature, then it seems appropriate for medical education to be further developed to emphasize these ideas.

  14. The post-synaptic density of human postmortem brain tissues: an experimental study paradigm for neuropsychiatric illnesses.

    Full Text Available Recent molecular genetics studies have suggested various trans-synaptic processes for pathophysiologic mechanisms of neuropsychiatric illnesses. Examination of pre- and post-synaptic scaffolds in the brains of patients would greatly aid further investigation, yet such an approach in human postmortem tissue has yet to be tested. We have examined three methods using density gradient based purification of synaptosomes followed by detergent extraction (Method 1 and the pH based differential extraction of synaptic membranes (Methods 2 and 3. All three methods separated fractions from human postmortem brains that were highly enriched in typical PSD proteins, almost to the exclusion of pre-synaptic proteins. We examined these fractions using electron microscopy (EM and verified the integrity of the synaptic membrane and PSD fractions derived from human postmortem brain tissues. We analyzed protein composition of the PSD fractions using two dimensional liquid chromatography tandem mass spectrometry (2D LC-MS/MS and observed known PSD proteins by mass spectrometry. Immunoprecipitation and immunoblot studies revealed that expected protein-protein interactions and certain posttranscriptional modulations were maintained in PSD fractions. Our results demonstrate that PSD fractions can be isolated from human postmortem brain tissues with a reasonable degree of integrity. This approach may foster novel postmortem brain research paradigms in which the stoichiometry and protein composition of specific microdomains are examined.

    Pigeon lice are insects that feed on feathers of these birds; their life cycle includes egg, nymph and adult and they may cause dermatoses in humans. Four persons of the same family, living in an urban area, presented with widespread intensely pruritic erythematous papules. A great number of lice were seen in their house, which moved from a nest of pigeons located on the condenser of the air-conditioning to the dormitory of one of the patients. Even in urban environments, dermatitis caused by parasites of birds is a possibility in cases of acute prurigo simplex. Pigeon lice are possible etiological agents of this kind of skin eruption, although they are often neglected, even by dermatologists.

    Full Text Available Background: Stigma associated with mental illnesses is one of the principal causes for mentally ill people not receiving adequate mental health care and treatment. The study was conducted to assess the extent of stigma associated with mental illness and knowledge of mental illness among the community. Materials and Methods: Community-based, cross-sectional study was conducted among 445 respondents from Udupi district; the community attitude toward the mentally ill (CAMI scale was used to assess stigma. The probability proportional to sampling size technique was adopted to select the wards/blocks. Household from blocks/wards were selected using convenience sampling. Self- administered semi-structured questionnaire was used to collect the information. Data was analyzed using the software SPSS version 15. Results: Of the total 445 respondents, the prevalence of stigma toward mentally ill people was 74.61% (95% confidence interval, 0.7057, 0.7866. The prevalence of stigma was high under all the four domains of CAMI scale. High prevalence of stigma was seen among females and people with higher income. Conclusions: The overall prevalence of stigma toward PWMI was found to be high. The stigma toward PWMI was associated with gender with respect to AU, BE and CMHI. Hence, the study suggests that there is a strong need to eliminate stigma associated with mental illness to improve the mental health status of the region.

  17. Beliefs about causation of schizophrenia: do Indian families believe in supernatural causes?

    Beliefs about the causation of schizophrenia could influence the attitudes patients' families adopt towards the patient and may also influence their help-seeking behaviour. Indian families have been typically described as often believing in causes like supernatural forces and therefore seeking help from magico-religious healers. In the changing mental health scenario in India, this impression needs verification. Key relatives living with 254 chronic schizophrenia patients were interviewed and asked to name the causes they believed were behind the illness. A list of possible causes was provided for the families to select from, and relatives were also encouraged to mention other possible causes, not featured in the list. The possible causes identified and the factors related to attributions made were analysed. A supernatural cause was named by only 12% of the families and as the only cause by 5%. Psychosocial stress was most commonly cited cause, followed by personality defect and heredity. A small number of families (14%) could not name any cause and 39% named more than one cause. Patient gender and education, duration of illness and the key relative's education and the nature of relationship were related to the type of causal attributions made. Families living with patients suffering chronic schizophrenia receiving treatment in urban India rarely subscribe to the idea of supernatural causation of the illness. The causal attributions made by them are fairly rational and understandable, given the relative lack of exposure to proper information about the illness.

    Fagan, Kathleen M; Hodgson, Michael J

    2017-02-01

    A 2009 Government Accounting Office (GAO) report, along with numerous published studies, documented that many workplace injuries are not recorded on employers' recordkeeping logs required by the Occupational Safety and Health Administration (OSHA) and consequently are under-reported to the Bureau of Labor Statistics (BLS), resulting in a substantial undercount of occupational injuries in the United States. OSHA conducted a Recordkeeping National Emphasis Program (NEP) from 2009 to 2012 to identify the extent and causes of unrecorded and incorrectly recorded occupational injuries and illnesses. OSHA found recordkeeping violations in close to half of all facilities inspected. Employee interviews identified workers' fear of reprisal and employer disciplinary programs as the most important causes of under-reporting. Subsequent inspections in the poultry industry identified employer medical management policies that fostered both under-reporting and under-recording of workplace injuries and illnesses. OSHA corroborated previous research findings and identified onsite medical units as a potential new cause of both under-reporting and under-recording. Research is needed to better characterize and eliminate obstacles to the compilation of accurate occupational injury and illness data. Occupational health professionals who work with high hazard industries where low injury rates are being recorded may wish to scrutinize recordkeeping practices carefully. This work suggests that, although many high-risk establishments manage recordkeeping with integrity, the lower the reported injury rate, the greater the likelihood of under-recording and under-reporting of work-related injuries and illnesses.

    Full Text Available Liver diseases are one of the main causes of death, and their ever-increasing prevalence is threatening to cause significant damage both to individuals and society as a whole. This damage is especially serious for the economically active population in Korea. From the societal perspective, it is therefore necessary to consider the economic impacts associated with liver diseases, and identify interventions that can reduce the burden of these diseases. The cost-of-illness study is considered to be an essential evaluation technique in health care. By measuring and comparing the economic burdens of diseases to society, such studies can help health-care decision-makers to set up and prioritize health-care policies and interventions. Using economic theories, this paper introduces various study methods that are generally applicable to most disease cases for estimating the costs of illness associated with mortality, morbidity, disability, and other disease characteristics. It also presents concepts and scopes of costs along with different cost categories from different research perspectives in cost estimations. By discussing the epidemiological and economic grounds of the cost-of-illness study, the reported results represent useful information about several evaluation techniques at an advanced level, such as cost-benefit analysis, cost-effectiveness analysis, and cost-utility analysis.

    Full Text Available Abstract Background This study was designed to examine the knowledge, attitude and beliefs about causes, manifestations and treatment of mental illness among adults in a rural community in northern Nigeria. Methods A cross sectional study design was used. A pre-tested, semi-structured questionnaire was administered to 250 adults residing in Karfi village, northern Nigeria. Results The most common symptoms proffered by respondents as manifestations of mental illness included aggression/destructiveness (22.0%, loquaciousness (21.2%, eccentric behavior (16.1% and wandering (13.3%. Drug misuse including alcohol, cannabis, and other street drugs was identified in 34.3% of the responses as a major cause of mental illness, followed by divine wrath/ God's will (19%, and magic/spirit possession (18.0%. About 46% of respondents preferred orthodox medical care for the mentally sick while 34% were more inclined to spiritual healing. Almost half of the respondents harbored negative feelings towards the mentally ill. Literate respondents were seven times more likely to exhibit positive feelings towards the mentally ill as compared to non-literate subjects (OR = 7.6, 95% confidence interval = 3.8–15.1. Conclusions Our study demonstrates the need for community educational programs in Nigeria aimed at demystifying mental illness. A better understanding of mental disorders among the public would allay fear and mistrust about mentally ill persons in the community as well as lessen stigmatization towards such persons.

The modified and validated Chinese version of the illness perception questionnaire-revised was utilized, which contained three sections: symptom identity, illness representation, and causes. The 12-item short-form health survey was utilized to reflect the physical and mental health-related quality of life (HRQoL. The Toronto alexithymia scale was used to measure the severity of alexithymia. Additional behavioral outcome about the frequency of doctor visits in the past 12 months was measured. Pathway analyses with multiple-group comparisons were conducted to test the mediating role of illness perception.ResultsOverall, 600 patients were recruited. The illness perceptions of FGID patients were characterized as with broad non-gastrointestinal symptoms (6.8 ± 4.2, a negative illness representation (more chronic course, worse consequences, lower personal and treatment control, lower illness coherence, and heavier emotional distress, and high numbers of psychological and culture-specific attributions. Fit indices of the three hypothesized path models (for physical and mental HRQoL and doctor-visit frequency, respectively supported the mediating role of illness perceptions. For example, the severity of alexithymia and non-gastrointestinal symptoms had significant negative effect on mental quality of life through both direct (standardized effect: −0.085 and −0.233 and indirect (standardized effect: −0.045 and −0.231 influence via subscales of consequences, emotional representation, and psychological and risk factor attributions.

    The on-going discussion about a new empiricism in the study of the medical humanities has lead to a misapprehension about the problems attendant to representing health and illness. The difficulty in understanding the politics of health and illness as well as the concomitant new aestheticism that has arisen concerning its representation demands a rethinking of these categories in the 21st century. Obesity can provide a model for the importance of this problem today.

    Patient's perception of their illness influences their healthcare decisions. The objectives of this study were to explore patient's own beliefs about their illness (Schizophrenia) and perceived social support, and its impact on their attitudes toward pharmacological treatment in Lahore, Pakistan. This study was conducted at Mayo Hospital Lahore from March to September 2016. Hundred individuals suffering from Schizophrenia completed four questionnaires; a socio-demographic questionnaire, the Illness Perception Questionnaire for Schizophrenia(IPQ-S), Drug attitude Inventory-10 (DAI) and Multidimensional Scale of Perceived Social Support (PSS). Stress, family problems, lack of friends & financial worries were endorsed strongly by patients as cause of their mental illness. Ambiguity regarding their mental illness duration and personal control was observed. Patients' perceived significant negative consequences, negative emotional response, as well as had poor understanding of their mental illness and treatment effectiveness. Statistically significant gender differences in treatment control and illness coherence subscales of IPQS were observed. Drug attitude inventory was positively correlated with Treatment control subscale (p Illness coherence subscale of IPQS (p consequences subscale and perceived social support was negatively correlated (p illness is predictor of their drug taking attitude and perceived social support. Study results should help to develop new interventions to correct inaccurate beliefs in patients with schizophrenia to improve illness outcome.

    The purpose of this article is to synthesize the current literature on parent and child asthma illness representations and their consequent impact on parent-child asthma shared management. This systematic review was conducted in concordance with the PRISMA statement. An electronic search of five computerized databases (PubMed, PsycINFO, CINAHL, Cochrane, and EMBASE) was conducted using the following key words: asthma, illness representation, and child. Due to the limited number of articles identified, the search was broadened to include illness perceptions as well. Studies were included if they were specific to asthma and included parent and/or child asthma illness representations or perception, were published after 2000, and available in English. Fifteen articles were selected for inclusion. All of the articles are descriptive studies that used cross-sectional designs. Seven of the studies used parent and child participants, eight used parents only, and none used only child participants. None of the selected studies describe child asthma illness representations, and only three describe parental asthma illness representations. Domains of illness representations, including symptoms, timeline, consequences, cause, and controllability were described in the remaining articles. Symptoms and controllability appear to have the most influence on parental asthma management practices. Parents prefer symptomatic or intermittent asthma management and frequently cite concerns regarding daily controller medication use. Parents also primarily rely on their own objective symptom observations rather than the child's report of symptoms. Asthma illness representations are an important area of future study to better understand parent-child shared asthma management.

    This aim of the review was to describe differences in ethical approaches to research on Internet communication during illness and to report conclusions drawn relevant to a proposed narrative analysis of parent blogs of childhood illness. As the study of the online expression of illness experiences becomes more expansive, discussion of related ethical issues is central to promoting research trustworthiness and rigour. Ethical considerations are central to the patient-provider relationship. The EBSCO Host, CINAHL, Medline, Communication & Mass Media Complete, and Google Scholar databases were searched from January 1990 to September 2009 using the terms 'Internet research and ethics', 'Internet research, illness and ethics' and 'blog, Internet research and ethics'. Of the 4114 references found, 21 met the inclusion criteria for the review. The review was designed to be a comprehensive assessment of the concepts analysed and the qualitative research measures taken concerning ethics in Internet research across formats. Three main approaches to ethical conduct in Internet research on illness experiences were found: human subjects, representation and open source approaches. The personal and sensitive nature of online illness narratives demand their consideration in health care as 'human subjects' research. The best hope for ethical treatment of author-participants is the creation of a comprehensive plan for addressing any and all potential ethical conflicts that may arise in the collection, analysis and reporting of data, taking into consideration rapid changes in technology. © 2011 Blackwell Publishing Ltd.

    We performed experiments to determine whether or not acetylcholine exerts a prejunctional inhibitory effect on adrenergic neurotransmission in the human blood vessel wall. Rings of human greater saphenous veins were prepared 2 to 15 hours after death and mounted for isometric tension recording in organ chambers filled with Krebs-Ringer solution. Acetylcholine depressed contractile responses to electric activation of the sympathetic nerve endings significantly more than those to exogenous norepinephrine; the relaxations caused by the cholinergic transmitter were antagonized by atropine. Helical strips were incubated with [/sub 3/H]norepinephrine and mounted for superfusion. Electric stimulation augmented the fractional release of labeled norepinephrine. Acetylcholine caused a depression of the evoked /sub 3/H release which was antagonized by atropine but not by hexamethonium. These experiments demonstrate that, as in animal cutaneous veins, there are prejunctional inhibitory muscarinic receptors on the adrenergic nerve endings in the human saphenous vein. By contrast, the human vein also contains postjunctional inhibitory muscarinic receptors

    Critically ill trauma patients undergo many radiologic studies, but the cumulative radiation dose is unknown. The purpose of this study was to estimate the cumulative effective dose (CED) of radiation resulting from radiologic studies in critically ill trauma patients. The study group was composed of trauma patients at an urban Level I trauma center with surgical intensive care unit length of stay (LOS) greater than 30 days. The radiology records were reviewed. A typical effective dose per study for each type of plain film radiograph, computed tomographic scan, fluoroscopic study, and nuclear medicine study was used to calculate CED. Forty-six patients met criteria. The mean surgical intensive care unit and hospital LOS were 42.7 +/- 14.0 and 59.5 +/- 28.5 days, respectively. The mean Injury Severity Score was 32.2 +/- 15.0. The mean number of studies per patient was 70.1 +/- 29.0 plain film radiographs, 7.8 +/- 4.1 computed tomographic scans, 2.5 +/- 2.6 fluoroscopic studies, and 0.065 +/- 0.33 nuclear medicine study. The mean CED was 106 +/- 59 mSv per patient (range, 11-289 mSv; median, 104 mSv). Among age, mechanism, Injury Severity Score, and LOS, there was no statistically significant predictor of high CED. The mean CED in the study group was 30 times higher than the average yearly radiation dose from all sources for individuals in the United States. The theoretical additional morbidity attributable to radiologic studies was 0.78%. From a radiobiologic perspective, risk-to-benefit ratios of radiologic studies are favorable, given the importance of medical information obtained. Current practice patterns regarding use of radiologic studies appear to be acceptable.

    Niki Papavramidou

    2014-01-01

    Full Text Available The Hippocratic Corpus played a key role to the disengagement of illness from the divine element that was believed to be to cause of all illnesses and injuries. Especially for the illnesses of the psyche (some call it “self” or “soul”, the Hippocratic physicians managed to recognize their biological origin and to create a “primitive” nosological structure. The aim of this paper is to identify the etiological factors of the illnesses of the psyche, according to the Hippocratic authors and to correlate them to modern medical observations. The Hippocratic physicians enumerated certain etiological factors for the occurrence of the illnesses of the psyche: imbalance of the humours, injuries of the head, extreme emotions, along with environmental features that were supposed to favor the appearance of such illnesses, such as the climate, the quality of the water, the winds, etc. Keywords: Hippocratic medicine; History of medicine; history of psychiatry; psyche

    The impact of the experience and diagnosis of mental illness on one's identity has long been recognized; however, little is known about the impact of illness identity, which we define as the set of roles and attitudes that a person has developed in relation to his or her understanding of having a mental illness. The present article proposes a theoretically driven model of the impact of illness identity on the course and recovery from severe mental illness and reviews relevant research. We propose that accepting a definition of oneself as mentally ill and assuming that mental illness means incompetence and inadequacy impact hope and self-esteem, which further impact suicide risk, coping, social interaction, vocational functioning, and symptom severity. Evidence supports most of the predictions made by the model. Implications for psychiatric rehabilitation services are discussed.

    Full Text Available Objective: This preliminary study examined the differences between what was taught during a formal medical education and medical students’ and psychiatry residents’ conceptions of notions regarding the causes and determinants of mental illness. Methods: The authors surveyed 74 medical students and 11 residents via convenience sampling. The survey contained 18 statements which were rated twice based on truthfulness in terms of a participant’s formal education and conception, respectively. Descriptive statistics and a Wilcoxon signed rank test determined differences between education and conception. Results: Results showed that students were less likely to perceive a neurotransmitter imbalance to cause mental illness, as opposed to what was emphasized during a formal medical education. Students and residents also understood the importance of factors such as systemic racism and socioeconomic status in the development of mental illness, which were factors that did not receive heavy emphasis during medical education. Furthermore, students and residents believed that not only did mental illnesses have nonuniform pathologies, but that the Diagnostic and Statistical Manual of Mental Disorders also had the propensity to sometimes arbitrarily categorize individuals with potentially negative consequences. Conclusions: If these notions are therefore part of students’ and residents’ conceptions, as well as documented in the literature, then it seems appropriate for medical education to be further developed to emphasize these ideas.

    Full Text Available INTRODUCTION: At a time when a great number of diseases can be prevented by changing one's habits and life style, investigations have focused on understanding what adults and children believe to be desirable health practices and uncovering the factors associated with successful adherence to such practices. For these, causal attributions for health and illness were investigated among 96 Brazilian elementary school students. METHODS: Ninety six subjects, aged 6 to 14, were interviewed individually and their causal attributions were assessed through 14 true-false items (e.g. people stay well [healthy] because they are lucky. The relationship between the children's causal attributions and demographic characteristics were also examined. RESULTS: Overall, the results were consistent with previous researches. "Taking care of oneself" was considered the most important cause of good health. "Viruses and germs" and "lack of self-care" were the most selected causes of illness. Analyses revealed significant relationship between subjects' causal attribution and their age, school grade level, socioeconomic status and gender. CONCLUSIONS: The study findings suggest that there may be more cross-cultural similarities than differences in children's causal attributions for health and illness. Finding ways to help individuals engage in appropriate preventive-maintenance health practices without developing an exaggerated notion that the individuals can control their own health and illness is a challenge which remains to be addressed by further research.

    Full Text Available BACKGROUND: Public understanding about mental illnesses and attitudes towards people with mental illness (PWMI play a paramount role in the prevention and treatment of mental illness and the rehabilitation of PWMI. The aim of this study was to measure public stigma against PWMI and the factors associated with stigma in the Gilgel Gibe Field Research Center (GGFRC in Southwest Ethiopia. METHODS: This community-based, cross-sectional study was conducted from June to August 2012 among 845 randomly selected respondents by using the Community Attitudes towards the Mentally Ill (CAMI scale, an interviewer-administered questionnaire. Data was entered with EPI-DATA and then exported to STATA for analysis. Simple descriptive and linear regression analyses were performed to identify predictors of stigma against PWMI. RESULTS: Of the total of 845 respondents, 68.17% were from rural districts. The mean stigma score was 2.62 on a 5-point score. The majority of the respondents (75.27% believed that mental illness can be cured. Stress, poverty, and rumination were the most often perceived causes of mental illness. Rural residents had significantly higher stigma scores (std. β = 0.61, P<0.001. A statistically significant inverse relationship was found between the level of education and degree of stigma (std. β = -0.14, P<0.01, while higher income was significantly associated with more stigma (std. β = 0.07, P<0.05. Respondents with higher scores for perceived supernatural causes (std. β = -0.09, P<0.01 and perceived psychosocial and biological causes (std. β = -0.14, P<0.001 had significantly lower stigma levels. CONCLUSIONS: The study found a more undermining but less avoidant attitude towards PWMI. Rural residents showed higher levels of stigma. Stigma against PWMI was lower in people with an explanatory concept about the causes of mental illness and a higher level of education. Information, education, and communication about the

    Since the 1950s food safety hazards have been categorized simply as (micro) biological, chemical or physical hazards with no clear differentiation between those that cause acute and chronic harm. Indeed international risk assessment methods, including hazard analysis critical control point (HACCP) use these criteria. However, the spectrum of food related illness continues to grow now encompassing food allergy and intolerance, obesity, type 2 diabetes, stroke, heart disease, cancer as well as food poisoning, foodborne illness and food contamination. Therefore over a half-century later is this the time to redefine the spectrum of what constitutes food related illness? This paper considers whether such "redefinition" of food related intoxicating and infectious agents would provide more targeted policy instruments and lead to better risk assessment and thus mitigation of such risk within the food supply chain.

    Illness perceptions have been shown to be important determinants of functional and psychosocial outcomes, including quality of life and treatment adherence in end-stage renal disease patients. The aim of this prospective study was to determine whether haemodialysis patients' illness perceptions impact upon survival. Haemodialysis patients from a UK renal service completed the Revised Illness Perception Questionnaire. Over the study period (May 2007 to December 2010), all-cause mortality was recorded as the endpoint. 223 patients were followed up for a median of 15.9 months (min. 10 days, max. 42.7 months). The median dialysis vintage was 17.6 months (min. 4 days, max. 391.3 months). Treatment control perceptions demonstrated a significant association with mortality (HR = 0.91, 95% CI: 0.83-0.99, p = 0.03). After controlling for covariates, including age, albumin, extra renal comorbidity and depression scores, perception of treatment control remained a significant predictor of mortality (HR = 0.89, 95% CI: 0.80-0.99, p = 0.03). Patients' perceptions of treatment control (dialysis therapy) predict survival independently of survival risk factors, including comorbidity. Studies are required to test whether psychological interventions designed to modify maladaptive illness perceptions influence clinical outcomes in this patient setting. Copyright © 2011 S.

    There are no published data on influenza trends in Angola, where pneumonia is a leading cause of death among young children. This study aims to describe the seasonal trends, types, and subtypes of influenza virus recovered from patients with respiratory illness who were admitted to the major children's hospital in Angola from May 2009 through April 2011. Nasal and oral swabs were collected from patients seen in the outpatient clinic with influenza-like illness (ILI) or hospitalized with severe acute respiratory illness (SARI) and tested for influenza virus by polymerase chain reaction assays. Of 691 samples collected, 334 (48%) were from case patients with ILI, and 357 (52%) were from case patients with SARI. Most (86%) of these children were Angola.

    Background/Introduction: Perceptions about the aetiology of mental illness are likely to influence help-seeking behaviour. Understanding help-seeking behaviour will improve service provision and access. Therefore, this is likely to improve treatment outcomes. We assessed the perceptions and help-seeking behaviours surrounding mental illness in a Trinidadian population of 158 tertiary-level students (136 female, 22 male; mean age 30) by analysing their responses to a questionnaire which asked for responses regarding a case vignette of a 25-year-old young woman exhibiting symptoms suggestive of schizophrenia. Of the respondents, 32.3% attributed the symptoms to supernatural causes. Specifically, 27.8% to someone doing her bad and 24.1% to evil spirits. In all, 77.2% of respondents indicated that mental illness was caused by medical problems and 63.3% to work stress. A minimum of 9.5% of the students therefore have dual perceptions regarding causation (77.2 + 32.3 = 109.5) Those who perceived causation to be supernatural said they would seek help from both medical ( p = .000) and supernatural ( p = .000) modalities. This also applied significantly to those who said the causation was medical, that is, seeking both religious intervention ( p = .000) and medical intervention (.000) as the first path in the health-seeking pathway. Dual help-seeking behaviour seems to be the functional result of an integration of religious and medical models of mental illness causation even in respondents who clearly identified only one of these as the likely cause of the illness behaviour.

    The gut has long been hypothesized to be the 'motor' of multiple organ dysfunction syndrome. This review serves as an update on new data elucidating the role of the gut as the propagator of organ failure in critical illness. Under basal conditions, the gut absorbs nutrients and serves as a barrier that prevents approximately 40 trillion intraluminal microbes and their products from causing host injury. However, in critical illness, gut integrity is disrupted with hyperpermeability and increased epithelial apoptosis, allowing contamination of extraluminal sites that are ordinarily sterile. These alterations in gut integrity are further exacerbated in the setting of preexisting comorbidities. The normally commensal microflora is also altered in critical illness, with increases in microbial virulence and decreases in diversity, which leads to further pathologic responses within the host. All components of the gut are adversely impacted by critical illness. Gut injury can not only propagate local damage, but can also cause distant injury and organ failure. Understanding how the multifaceted components of the gut interact and how these are perturbed in critical illness may play an important role in turning off the 'motor' of multiple organ dysfunction syndrome in the future.

    Preschool rhinovirus (RV) wheezing illnesses predict an increased risk of childhood asthma; however, it is not clear how specific viral illnesses in early life relate to lung function later on in childhood. To determine the relationship of virus-specific wheezing illnesses and lung function in a longitudinal cohort of children at risk for asthma. Two hundred thirty-eight children were followed prospectively from birth to 8 years of age. Early life viral wheezing respiratory illnesses were assessed by using standard techniques, and lung function was assessed annually by using spirometry and impulse oscillometry. The relationships of these virus-specific wheezing illnesses and lung function were assessed by using mixed-effect linear regression. Children with RV wheezing illness demonstrated significantly decreased spirometry values, FEV(1) (P = .001), FEV(0.5) (P Children who wheezed with respiratory syncytial virus or other viral illnesses did not have any significant differences in spirometric or impulse oscillometry indices when compared with children who did not. Children diagnosed with asthma at ages 6 or 8 years had significantly decreased FEF(25-75) (P = .05) compared with children without asthma. Among outpatient viral wheezing illnesses in early childhood, those caused by RV infections are the most significant predictors of decreased lung function up to age 8 years in a high-risk birth cohort. Whether low lung function is a cause and/or effect of RV wheezing illnesses is yet to be determined. Copyright © 2011 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc.

    Brazil will host the 2014 FIFA World Cup and the 2016 Olympic and Paralympic Games, events that are expected to attract hundreds of thousands of international travelers. Travelers to Brazil will encounter locally endemic infections as well as mass event-specific risks. We describe 1586 ill returned travelers who had visited Brazil and were seen at a GeoSentinel Clinic from July 1997 through May 2013. The most common travel-related illnesses were dermatologic conditions (40%), diarrheal syndromes (25%), and febrile systemic illness (19%). The most common specific dermatologic diagnoses were cutaneous larva migrans, myiasis, and tungiasis. Dengue and malaria, predominantly Plasmodium vivax, were the most frequently identified specific causes of fever and the most common reasons for hospitalization after travel. Dengue fever diagnoses displayed marked seasonality, although cases were seen throughout the year. Among the 28 ill returned travelers with human immunodeficiency virus (HIV) infection, 11 had newly diagnosed asymptomatic infection and 9 had acute symptomatic HIV. Our analysis primarily identified infectious diseases among travelers to Brazil. Knowledge of illness in travelers returning from Brazil can assist clinicians to advise prospective travelers and guide pretravel preparation, including itinerary-tailored advice, vaccines, and chemoprophylaxis; it can also help to focus posttravel evaluation of ill returned travelers. Travelers planning to attend mass events will encounter other risks that are not captured in our surveillance network.

  10. Information processing in illness representation: Implications from an associative-learning framework.

    2017-03-01

    The common-sense model (Leventhal, Meyer, & Nerenz, 1980) outlines how illness representations are important for understanding adjustment to health threats. However, psychological processes giving rise to these representations are little understood. To address this, an associative-learning framework was used to model low-level process mechanics of illness representation and coping-related decision making. Associative learning was modeled within a connectionist network simulation. Two types of information were paired: Illness identities (indigestion, heart attack, cancer) were paired with illness-belief profiles (cause, timeline, consequences, control/cure), and specific illness beliefs were paired with coping procedures (family doctor, emergency services, self-treatment). To emulate past experience, the network was trained with these pairings. As an analogue of a current illness event, the trained network was exposed to partial information (illness identity or select representation beliefs) and its response recorded. The network (a) produced the appropriate representation profile (beliefs) for a given illness identity, (b) prioritized expected coping procedures, and (c) highlighted circumstances in which activated representation profiles could include self-generated or counterfactual beliefs. Encoding and activation of illness beliefs can occur spontaneously and automatically; conventional questionnaire measurement may be insensitive to these automatic representations. Furthermore, illness representations may comprise a coherent set of nonindependent beliefs (a schema) rather than a collective of independent beliefs. Incoming information may generate a "tipping point," dramatically changing the active schema as a new illness-knowledge set is invoked. Finally, automatic activation of well-learned information can lead to the erroneous interpretation of illness events, with implications for [inappropriate] coping efforts.

    The aim of the study was to examine the ethnic differences in knowledge, attitude and practice towards mental illness in a sample of Qatari and non-Qatari Arabs. This is a cross sectional survey conducted in Primary Health Care centers, Qatar from October to June 2009. A representative sample of 3000 Qatari and non-Qatari Arabs above 20 years of age were approached and 2514 subjects (83.8%) gave consent to participate in this study. More than non-Qatari Arabs, a significant proportion of Qataris thought that mental illness can be a punishment from God (44.5% vs 50.6%; p=0.002) and that people with mental illness are mentally retarded (35.1% vs 45.1%; pnationals had a poor knowledge about causes of mental illness compared to non-Qatari Arabs such as a belief that mental illness is due to possession of evil spirits (40.5% vs 37.6%) and psychiatric medication will cause addiction (61% vs 57.3%). The study revealed that there is an ethnic diversity within Arab societies in their knowledge, attitude and practice towards mental illness.

Stigma against PWMI was lower in people with an explanatory concept about the causes of mental illness and a higher level of education. Information, education, and communication about the causes, signs, and nature of mental illnesses would help to reduce stigma.

    This study explored the perceptions of 18 people diagnosed with schizophrenia from 1-10 years to uncover how they perceived themselves and their illness. It also involved 12 family members who added their perceptions. The data were collected using in-depth interviews, reflective journaling, and observations. The data were analyzed through the lens of Heidegger's hermeneutic phenomenology. Four themes emerged: perceptions of mental illness, perceptions of the causes of illness, perceptions of discrimination, and attempting to live with schizophrenia. The findings included strong underlying cultural and spiritual beliefs, and attitudes unique to the Thai participants, including the causation of schizophrenia by supernatural powers, black magic, and bad karma stemming from past deeds. Understanding the perceptions of the participants might help health-care providers to be more sensitive to those living with schizophrenia in Thailand and elsewhere. In particular, the findings could be useful in informing psychiatric careproviders about developing better caring systems for clients diagnosed with schizophrenia. This should help the sufferers of schizophrenia to live their lives to their own satisfaction and as normally as possible.

    Extreme heat events have occurred more frequently in China in recent years, leading to serious impacts on human life and the health care system. To identify the characteristics of individuals with heat-related illnesses in China during the summer of 2013, we collected the data from the Heat-related Illness Surveillance System in Chinese Center for Disease Control and Prevention (China CDC). A total of 5758 cases were reported in the summer of 2013, mostly concentrated in urban areas around the middle and lower reaches of the Yangtze River. We found a difference in age distribution of percentage of deaths from heat-related illness between males and females. Severe cases in males mostly occurred in the age group 45-74 years but in females mostly in the age group over 75. A distributed lag non-linear model had been used to identify population vulnerabilities in Ningbo and Chongqing. The results show that there was a clear positive relationship between maximum temperature and heat-related illness, and the heat effect was nonlinear and could last for 3 days. The elderly and males in the range of 45-64 years old might be the most vulnerable people of heat-related illness in China. We also highlighted some deficiencies of the surveillance system, such that the reported data were not accurate, comprehensive, or timely enough at this stage.

    Full Text Available During 2009–2010, a total of 1,527 foodborne disease outbreaks were reported by the Centers for Disease Control and Prevention (CDC (2013. However, in a 2011 CDC report, Scallan et al. estimated about 48 million people contract a foodborne illness annually in the United States. Public health officials are concerned with this under-reporting; thus, the purpose of this study was to identify why consumers and healthcare professionals don’t report foodborne illness. Focus groups were conducted with 35 consumers who reported a previous experience with foodborne illness and with 16 healthcare professionals. Also, interviews with other healthcare professionals with responsibility of diagnosing foodborne illness were conducted. Not knowing who to contact, being too ill, being unsure of the cause, and believing reporting would not be beneficial were all identified by consumers as reasons for not reporting foodborne illness. Healthcare professionals that participated in the focus groups indicated the amount of time between patients’ consumption of food and seeking treatment and lack of knowledge were barriers to diagnosing foodborne illness. Issues related to stool samples such as knowledge, access and cost were noted by both groups. Results suggest that barriers identified could be overcome with targeted education and improved access and information about the reporting process.

    Full Text Available Acute appendicitis is considered the most common cause of emergency surgery in children and young adults. The association between parasitic infections and appendicitis has been widely investigated. Hydatidosis, a zoonotic helminthic disease caused by the larval stage of the Echinococcus granulosus, may cause illness in intermediate hosts, generally human and herbivorous animals. This disease is considered hyper endemic in northwest of Iran and is a serious public health problem. Hydatidosis predominantly is located in internal organs especially liver and lung but is considered a rare cause of acute appendicitis. Our aim was to study hydatid cyst that causes appendicitis. In this retrospective descriptive, 275 appendectomies performed during the years 2007-2012 in Tabriz Emam Reza hospital. Depending on the clinical notes, serological method, laboratory, surgical findings and attention to the histopathologic results, we found a patient with appendiceal hydatidosis. Acute appendicitis of hydatidosis origin is not seen frequently even in the hyper endemic area. Therefore, described an unusual cases of hydatidosis, should be considered in the differential diagnoses of appendicitis also education on how to prevent hydatidosis and eradication of stray dogs should be included in training programs to avoid and decrease the appendectomy operations.

    Since numerious physiological systems display muscarinic receptor supersensitivity in major depressive illnesses, the authors have hypothesize that anterior pituitary release of ACTH and beta-Endorphin immunoreactivity may also be muscarinically supersensitive in depression. The studies were conducted under FDA-approved IND and with local human subjects committee approval. Plasma ACTH concentrations were determined as follows: samples were assayed in duplicate using equilibrium radioimmunoassay utilizing a rabbit anti-porcine ACTH antibody. Significance ofchanges in plasma cortisol, ACTH and beta-endorphin immunoreactivity after physostigmine and saline were determined by repeated measures analysis of variance. In all subject groups, physostigmine (relative to placebo) caused significant increases in plasma concentrations of cortisol, ACTH, and beta-endorphin immonoreactivity

  2. Probiotics in critically ill children [version 1; referees: 2 approved

    Full Text Available Gut microflora contribute greatly to immune and nutritive functions and act as a physical barrier against pathogenic organisms across the gut mucosa. Critical illness disrupts the balance between host and gut microflora, facilitating colonization, overgrowth, and translocation of pathogens and microbial products across intestinal mucosal barrier and causing systemic inflammatory response syndrome and sepsis. Commonly used probiotics, which have been developed from organisms that form gut microbiota, singly or in combination, can restore gut microflora and offer the benefits similar to those offered by normal gut flora, namely immune enhancement, improved barrier function of the gastrointestinal tract (GIT, and prevention of bacterial translocation. Enteral supplementation of probiotic strains containing either Lactobacillus alone or in combination with Bifidobacterium reduced the incidence and severity of necrotizing enterocolitis and all-cause mortality in preterm infants. Orally administered Lactobacillus casei subspecies rhamnosus, Lactobacillus reuteri, and Lactobacillus rhamnosus were effective in the prevention of late-onset sepsis and GIT colonization by Candida in preterm very low birth weight infants. In critically ill children, probiotics are effective in the prevention and treatment of antibiotic-associated diarrhea. Oral administration of a mix of probiotics for 1 week to children on broad-spectrum antibiotics in a pediatric intensive care unit decreased GIT colonization by Candida, led to a 50% reduction in candiduria, and showed a trend toward decreased incidence of candidemia. However, routine use of probiotics cannot be supported on the basis of current scientific evidence. Safety of probiotics is also a concern; rarely, probiotics may cause bacteremia, fungemia, and sepsis in immunocompromised critically ill children. More studies are needed to answer questions on the effectiveness of a mix versus single-strain probiotics

    Full Text Available There is a growing consensus that climate is changing, but beliefs about the causal factors vary widely among the general public. Current research shows that such causal beliefs are strongly influenced by cultural, political, and identity-driven views. We examined the influence that local perceptions have on the acceptance of basic facts about climate change. We also examined the connection to wildfire by local people. Two recent telephone surveys found that 37% (in 2011 and 46% (in 2014 of eastern Oregon (USA respondents accept the scientific consensus that human activities are now changing the climate. Although most do not agree with that consensus, large majorities (85–86% do agree that climate is changing, whether by natural or human causes. Acceptance of anthropogenic climate change generally divides along political party lines, but acceptance of climate change more generally, and concerns about wildfire, transcend political divisions. Support for active forest management to reduce wildfire risks is strong in this region, and restoration treatments could be critical to the resilience of both communities and ecosystems. Although these immediate steps involve adaptations to a changing climate, they can be motivated without necessarily invoking human-caused climate change, a divisive concept among local landowners.

  5. Antioxidant Vitamins and Trace Elements in Critical Illness.

    This comprehensive narrative review summarizes relevant antioxidant mechanisms, the antioxidant status, and effects of supplementation in critically ill patients for the most studied antioxidant vitamins A, C, and E and the enzyme cofactor trace elements selenium and zinc. Over the past 15 years, oxidative stress-mediated cell damage has been recognized to be fundamental to the pathophysiology of various critical illnesses such as acute respiratory distress syndrome, ischemia-reperfusion injury, and multiorgan dysfunction in sepsis. Related to these conditions, low plasma levels of antioxidant enzymes, vitamins, and trace elements have been frequently reported, and thus supplementation seems logical. However, low antioxidant plasma levels per se may not indicate low total body stores as critical illness may induce redistribution of antioxidants. Furthermore, low antioxidant levels may even be beneficial as pro-oxidants are essential in bacterial killing. The reviewed studies in critically ill patients show conflicting results. This may be due to different patient populations, study designs, timing, dosing regimens, and duration of the intervention and outcome measures evaluated. Therefore, at present, it remains unclear whether supplementation of antioxidant micronutrients has any clinical benefit in critically ill patients as some studies show clear benefits, whereas others demonstrate neutral outcomes and even harm. Combination therapy of antioxidants seems logical as they work in synergy and function as elements of the human antioxidant network. Further research should focus on defining the normal antioxidant status for critically ill patients and to study optimal supplement combinations either by nutrition enrichment or by enteral or parenteral pharmacological interventions. © 2016 American Society for Parenteral and Enteral Nutrition.

    The thermoregulatory control of human skin blood flow is vital to maintain the body heat storage during challenges of thermal homeostasis under heat stress. Whenever thermal homeostasis disturbed, the heat load exceeds heat dissipation capacity, which alters the cutaneous vascular responses along with other body physiological variables. Whole body skin blood flow has been calculated from the forearm blood flow. Present model has been designed using electronics circuit simulator (Multisim 8.0, National Instruments, USA), is to execute a series of predictive equations for early prediction of physiological parameters of young nude subjects during resting condition at various level of dry heat stress under almost still air to avoid causalities associated with hot environmental. The users can execute the model by changing the environmental temperature in degrees C and exposure time in minutes. The model would be able to predict and detect the changes in human vascular responses along with other physiological parameters and from this predicted values heat related-illness symptoms can be inferred.

    Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. To analyse the injuries and illnesses that occurred during the XXII Olympic Winter Games, held in Sochi in 2014. We recorded the daily occurrence (or non-occurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the Sochi 2014 medical staff. NOC and Sochi 2014 medical staff reported 391 injuries and 249 illnesses among 2780 athletes from 88 NOCs, equalling incidences of 14 injuries and 8.9 illnesses per 100 athletes over an 18-day period of time. Altogether, 12% and 8% of the athletes incurred at least one injury or illness, respectively. The percentage of athletes injured was highest in aerial skiing, snowboard slopestyle, snowboard cross, slopestyle skiing, halfpipe skiing, moguls skiing, alpine skiing, and snowboard halfpipe. Thirty-nine per cent of the injuries were expected to prevent the athlete from participating in competition or training. Women suffered 50% more illnesses than men. The rate of illness was highest in skeleton, short track, curling, cross-country skiing, figure skating, bobsleigh and aerial skiing. A total of 159 illnesses (64%) affected the respiratory system, and the most common cause of illness was infection (n=145, 58%). Overall, 12% of the athletes incurred at least one injury during the games, and 8% an illness, which is similar to prior Olympic Games. The incidence of injuries and illnesses varied substantially between sports. Published by the BMJ Publishing Group Limited.

    The disease impact and economic burden of fibromyalgia (FM) are high for patients and society at large. Knowing potential determinants of economic costs may help in reducing this burden. Cognitive appraisals (perceptions) of the illness could affect costs. The present study estimated costs of illness in FM and examined the association between these costs and illness perceptions. Questionnaire data of FM severity (FIQ), illness perceptions (IPQ-R-FM), productivity losses (SF-HLQ) and health care use were collected in a cohort of patients with FM. Costs were calculated and dichotomised (median split). Univariate and hierarchic logistic regression models examined the unique association of each illness perception with 1) health care costs and 2) costs of productivity losses. Covariates were FM severity, comorbidity and other illness perceptions. 280 patients participated: 95% female, mean age 42 (SD=12) years. Annualised costs of FM per patient were €2944 for health care, and €5731 for productivity losses. In multivariate analyses, a higher disease impact (FIQ) and two of seven illness perceptions (IPQ-R-FM) were associated with high health care costs: 1) high scores on 'cyclical timeline' reflecting a fluctuating, unpredictable course and 2) low scores on 'emotional representations', thus not perceiving a connection between fibromyalgia and emotions. None of the variables was associated with productivity losses. Our study indicates that perceiving a fluctuating course and low emotional representation, which perhaps reflects somatic fixation, are associated with health care costs in FM. Future studies should examine whether targeting these illness perceptions results in reduction of costs.

  10. South African Muslim Faith Healers perceptions of mental illness: understanding, aetiology and treatment.

    The important role that religious beliefs may have on perceptions of mental illness cannot be ignored. Many religions including Islam advocate witchcraft and spirit possession--all of which are thought to influence the behaviour of a person so as to resemble that of a mentally ill individual. Thus this research explored Muslim Faith Healers perceptions of mental and spiritual illness in terms of their understanding of the distinctions between the two, the aetiologies and the treatments thereof. Six Muslim Healers in the Johannesburg community were interviewed and thematic content analysis was used to analyse the data. From the results it is clear that the faith healers were aware of the distinction between mental and spiritual illnesses. It was also apparent that Islam has a clear taxonomy that distinguishes illness and the causes thereof. Treatments are then advised accordingly. Thus this paper argues that the predominant Western view of the aetiology and understanding of mental illness needs to acknowledge the various culturally inclined taxonomies of mental illness so as to better understand and aid clients.

  11. The effect of subliminal evaluative conditioning of cognitive self-schema and illness schema on pain tolerance.

    Cognitive models explaining medically unexplained complaints propose that activating illness-related memory causes increased complaints such as pain. However, our previous studies showed conflicting support for this theory. Illness-related memory is more likely to influence reporting of complaints when its activation is enmeshed with that of self-related memory. We, therefore, investigated whether inducing this association would cause a stronger decrease in pain tolerance. In addition, we examined whether SFA acted as a moderator of this effect. We used subliminal evaluative conditioning (SEC) to induce an association between activated self-related and illness-related memory. Seventy-six participants were randomly assigned to four combinations of two priming factors: (1) the self-referent word "I" versus the nonself-referent "X" to manipulate activated self-related memory and (2) health complaint (HC) words versus neutral words to manipulate activated illness-related memory. Pain tolerance was assessed using a cold pressor task (CPT). Participants primed with the self-referent "I" and HC words did not demonstrate the expected lower pain tolerance. However, SFA acted as a moderator of the main effect of the self-prime: priming with "I" resulted in increased pain tolerance in participants with low SFA. The current study did not support the hypothesis that associations between activated self-related memory and illness-related memory cause increased reporting of complaints. Instead, activating self-related memory increased pain tolerance in participants with low SFA. This seems to indicate that the self-prime might cause an increase in SFA and suggests possible new ways to promote adaptive coping with pain.

    the underlying literature. There are no studies of level 1 evidence proving the positive impact of the tested interventions on the critically ill patients sleep pattern. Thus, disturbed sleep in critically ill patients with all the severe consequences remains an unresolved problem and needs further investigation.......Sleep disturbances in the intensive care unit (ICU) seem to lead to development of delirium, prolonged ICU stay, and increased mortality. That is why sufficient sleep is important for good outcome and recovery in critically ill patients. A variety of small studies reveal pathological sleep patterns...... in critically ill patients including abnormal circadian rhythm, high arousal and awakening index, reduced Slow Wave Sleep, and Rapid Eye Movement sleep. The purpose of this study is to summarise different aspects of sleep-awake disturbances, causes and handling methods in critically ill patients by reviewing...

    Full Text Available As part of a virus discovery investigation using a metagenomic approach, a highly divergent novel Human papillomavirus type was identified in pooled convenience nasal/oropharyngeal swab samples collected from patients with febrile respiratory illness. Phylogenetic analysis of the whole genome and the L1 gene reveals that the new HPV identified in this study clusters with previously described gamma papillomaviruses, sharing only 61.1% (whole genome and 63.1% (L1 sequence identity with its closest relative in the Papillomavirus episteme (PAVE database. This new virus was named HPV_SD2 pending official classification. The complete genome of HPV-SD2 is 7,299 bp long (36.3% G/C and contains 7 open reading frames (L2, L1, E6, E7, E1, E2 and E4 and a non-coding long control region (LCR between L1 and E6. The metagenomic procedures, coupled with the bioinformatic methods described herein are well suited to detect small circular genomes such as those of human papillomaviruses.

  14. Psychogenic Explanations of Physical Illness: Time to Examine the Evidence.

    In some patients with chronic physical complaints, detailed examination fails to reveal a well-recognized underlying disease process. In this situation, the physician may suspect a psychological cause. In this review, we critically evaluated the evidence for this causal claim, focusing on complaints presenting as neurological disorders. There were four main conclusions. First, patients with these complaints frequently exhibit psychopathology but not consistently more often than patients with a comparable "organic" diagnosis, so a causal role cannot be inferred. Second, these patients report a high incidence of adverse life experiences, but again, there is insufficient evidence to indicate a causal role for any particular type of experience. Third, although psychogenic illnesses are believed to be more responsive to psychological interventions than comparable "organic" illnesses, there is currently no evidence to support this claim. Finally, recent evidence suggests that biological and physical factors play a much greater causal role in these illnesses than previously believed. We conclude that there is currently little evidential support for psychogenic theories of illness in the neurological domain. In future research, researchers need to take a wider view concerning the etiology of these illnesses. © The Author(s) 2016.

    Knowledge about culture- and migration-specific characteristics of subjective illness beliefs in Turkish patients is necessary for adequate treatment. Analysis of subjective illness beliefs in Turkish patients (F3; F4; n = 79) in comparison to matched Germans (n = 79) using a modified version of the Illness Perception Questionnaire IPQ-R. Differences were explored by t-tests and chi(2)-tests. Turkish patients believed significantly stronger in a chronical timeline of illness and in negative illness consequences, while German patients believed significantly stronger in treatment control and personal control. Turkish patients more often mentioned external causes of their disease compared to Germans. The results provide explanations of the deficient health care situation for Turkish migrants in Germany.

    We conducted a retrospective chart review of human immunodeficiency virus (HIV)-infected patients who died in 1995 and in 1999-2000. We found an increase in the proportion of patients who died from an illness that was not related to acquired immunodeficiency syndrome (AIDS). Although there was a decrease in the prevalence of AIDS-defining illnesses, >85% of patients died with CD4 counts of 50% of HIV-infected patients who died were not receiving HAART. AIDS-defining illnesses continue to be a major cause of mortality in the HAART era in populations where access to care and adherence to HAART is limited.

  17. Fatal degenerative neurologic illnesses in men who participated in wild game feasts--Wisconsin, 2002.

    Science.gov (United States)

    2003-02-21

    Creutzfeldt-Jakob disease (CJD) is a fatal neurologic disorder in humans. CJD is one of a group of conditions known as transmissible spongiform encephalopathies (TSEs), or prion diseases, that are believed to be caused by abnormally configured, host-encoded prion proteins that accumulate in the central nervous tissue. CJD has an annual incidence of approximately 1 case per million population in the United States and occurs in three forms: sporadic, genetically determined, and acquired by infection. In the latter form, the incubation period is measured typically in years. Recent evidence that prion infection can cross the species barrier between humans and cattle has raised increasing public health concerns about the possible transmission to humans of a TSE among deer and elk known as chronic wasting disease (CWD). During 1993-1999, three men who participated in wild game feasts in northern Wisconsin died of degenerative neurologic illnesses. This report documents the investigation of these deaths, which was initiated in August 2002 and which confirmed the death of only one person from CJD. Although no association between CWD and CJD was found, continued surveillance of both diseases remains important to assess the possible risk for CWD transmission to humans.

    Exposure to heat and hot environments puts workers at risk for heat stress, which can result in heat illnesses and death. This report describes findings from a review of 2012‒2013 Occupational Safety and Health Administration (OSHA) federal enforcement cases (i.e., inspections) resulting in citations under paragraph 5(a)(1), the "general duty clause" of the Occupational Safety and Health Act of 1970. That clause requires that each employer "furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees". Because OSHA has not issued a heat standard, it must use 5(a)(1) citations in cases of heat illness or death to enforce employers' obligations to provide a safe and healthy workplace. During the 2-year period reviewed, 20 cases of heat illness or death were cited for federal enforcement under paragraph 5(a)(1) among 18 private employers and two federal agencies. In 13 cases, a worker died from heat exposure, and in seven cases, two or more employees experienced symptoms of heat illness. Most of the affected employees worked outdoors, and all performed heavy or moderate work, as defined by the American Conference of Governmental Industrial Hygienists. Nine of the deaths occurred in the first 3 days of working on the job, four of them occurring on the worker's first day. Heat illness prevention programs at these workplaces were found to be incomplete or absent, and no provision was made for the acclimatization of new workers. Acclimatization is the result of beneficial physiologic adaptations (e.g., increased sweating efficiency and stabilization of circulation) that occur after gradually increased exposure to heat or a hot environment. Whenever a potential exists for workers to be exposed to heat or hot environments, employers should implement heat illness prevention programs (including acclimatization requirements) at their

    The Olympic Movement Medical Code encourages all stakeholders to ensure that sport is practised without danger to the health of the athletes. Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. To analyse the injuries and illnesses that occurred during the Games of the XXX Olympiad, held in London in 2012. We recorded the daily occurrence (or non-occurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the London Organising Committee of the Olympic and Paralympic Games' (LOCOG) medical staff. In total, 10 568 athletes (4676 women and 5892 men) from 204 NOCs participated in the study. NOC and LOCOG medical staff reported 1361 injuries and 758 illnesses, equalling incidences of 128.8 injuries and 71.7 illnesses per 1000 athletes. Altogether, 11% and 7% of the athletes incurred at least one injury or illness, respectively. The risk of an athlete being injured was the highest in taekwondo, football, BMX, handball, mountain bike, athletics, weightlifting, hockey and badminton, and the lowest in archery, canoe slalom and sprint, track cycling, rowing, shooting and equestrian. 35% of the injuries were expected to prevent the athlete from participating during competition or training. Women suffered 60% more illnesses than men (86.0 vs 53.3 illnesses per 1000 athletes). The rate of illness was the highest in athletics, beach volleyball, football, sailing, synchronised swimming and taekwondo. A total of 310 illnesses (41%) affected the respiratory system and the most common cause of illness was infection (n=347, 46%). At least 11% of the athletes incurred an injury during the games and 7% of the athletes' an illness. The incidence of injuries and illnesses varied substantially among sports. Future initiatives should include the development of preventive measures tailored for each specific sport and the

    Social support and illness perceptions may affect recovery from a cardiac event or procedure. Previous research has found that patients of South Asian origin with coronary artery disease (CAD) have lower levels of social support and may perceive different causes of their condition. The purpose of this study was to quantitatively investigate differences in social support and illness perceptions between Caucasian and South Asian patients with CAD. A total of 562 inpatients with CAD (53 [9%] South Asian) were recruited from 2 hospitals. The Medical Outcomes Study social support scale and Illness Perception Questionnaire were administered to examine ethnocultural differences in total social support and subscales, and in illness perceptions subscales, including causes of illness. South Asian participants had significantly lower levels of tangible (P=.001) and emotional/informational support (P stress/worry (P=.04) and poor medical care in the past (P=.02) and less likely to attribute their illness to aging (P=.03) compared with Caucasian participants. Lower levels of social support among South Asians in Canada may have negative effects on recovery and prognosis. Our results support qualitative findings suggesting South Asians perceive their illness to be a result of fate or related to stress. Future studies should investigate interventions targeted at modifying illness perceptions among this group in an attempt to improve risk-reducing behavior and secondary prevention use.

    2014-03-01

    The present study applied the common sense model (i.e., cause, controllability, timeline, consequences, and illness coherence) to understand public attitudes toward mental illness and help-seeking intention and to examine the mediating role of perceived controllability between causal attributions with public attitudes and help seeking. Based on a randomized household sample of 941 Chinese community adults in Hong Kong, results of the structural equation modeling demonstrated that people who endorsed cultural lay beliefs tended to perceive the course of mental illness as less controllable, whereas those with psychosocial attributions see its course as more controllable. The more people perceived the course of mental illness as less controllable, more chronic, and incomprehensible, the lower was their acceptance and the greater was mental illness stigma. Furthermore, those who perceived mental illness with dire consequences were more likely to feel greater stigma and social distance. Conversely, when people were more accepting, they were more likely to seek help for psychological services and felt a shorter social distance. The common sense model provides a multidimensional framework in understanding public's mental illness perceptions and stigma. Not only should biopsychosocial determinants of mental illness be advocated to the public, cultural myths toward mental illness must be debunked.

    2006-09-15

    In the Mozart year 2006 also medicine has to deal with the music genius W.A. Mozart. It has been intensely discussed for a long time whether Mozart was poisoned, whether he deceased from a certain illness, or by self-medication and/or medical procedures. Consequently, his death caused wild speculations and adventurous assertions. Many authors assume that Mozart was a chronically ill man all his life. However, most of Mozart's described illnesses were harmless, and his unbelievable amount of work proves his extraordinary efficiency. The exact cause of death remains speculative. The story of a tall stranger dressed in somber gray who assigned Mozart to write a Requiem Mass and the circumstances of Mozart's funeral have additionally contributed to the generation of legends. However, if one gathers all known facts, there is no evidence that Mozart was murdered, and the exact cause of his death remains unclear.

    2018-03-01

    We present a review of the likely consequences of climate change for foodborne pathogens and associated human illness in higher-income countries. The relationships between climate and food are complex and hence the impacts of climate change uncertain. This makes it difficult to know which foodborne pathogens will be most affected, what the specific effects will be, and on what timescales changes might occur. Hence, a focus upon current capacity and adaptation potential against foodborne pathogens is essential. We highlight a number of developments that may enhance preparedness for climate change. These include the following: Adoption of novel surveillance methods, such as syndromic methods, to speed up detection and increase the fidelity of intervention in foodborne outbreaks Genotype-based approaches to surveillance of food pathogens to enhance spatiotemporal resolution in tracing and tracking of illness Ever increasing integration of plant, animal and human surveillance systems, One Health, to maximise potential for identifying threats Increased commitment to cross-border (global) information initiatives (including big data) Improved clarity regarding the governance of complex societal issues such as the conflict between food safety and food waste Strong user-centric (social) communications strategies to engage diverse stakeholder groups The impact of climate change upon foodborne pathogens and associated illness is uncertain. This emphasises the need to enhance current capacity and adaptation potential against foodborne illness. A range of developments are explored in this paper to enhance preparedness.

    The Great Xing'an Mountains are an important boreal forest region in China with high frequency of fire occurrences. With climate change, this region may have a substantial change in fire frequency. Building the relationship between spatial pattern of human-caused fire occurrence and its influencing factors, and predicting the spatial patterns of human-caused fires under climate change scenarios are important for fire management and carbon balance in boreal forests. We employed a spatial point pattern model to explore the relationship between the spatial pattern of human-caused fire occurrence and its influencing factors based on a database of historical fire records (1967-2006) in the Great Xing'an Mountains. The fire occurrence time was used as dependent variable. Nine abiotic (annual temperature and precipitation, elevation, aspect, and slope), biotic (vegetation type), and human factors (distance to the nearest road, road density, and distance to the nearest settlement) were selected as explanatory variables. We substituted the climate scenario data (RCP 2.6 and RCP 8.5) for the current climate data to predict the future spatial patterns of human-caused fire occurrence in 2050. Our results showed that the point pattern progress (PPP) model was an effective tool to predict the future relationship between fire occurrence and its spatial covariates. The climatic variables might significantly affect human-caused fire occurrence, while vegetation type, elevation and human variables were important predictors of human-caused fire occurrence. The human-caused fire occurrence probability was expected to increase in the south of the area, and the north and the area along the main roads would also become areas with high human-caused fire occurrence. The human-caused fire occurrence would increase by 72.2% under the RCP 2.6 scenario and by 166.7% under the RCP 8.5 scenario in 2050. Under climate change scenarios, the spatial patterns of human-caused fires were mainly

  7. Stigma towards people with mental illness in developing countries in Asia.

    Lauber, Christoph; Rössler, Wulf

    2007-04-01

    There is a wide range of literature on stigmatization and discrimination of people with mental illness. Most studies, however, derive from Western countries. This review aims at summarizing results from developing countries in Asia published between 1996-2006. Medline search focusing on English-speaking literature. Comparable to Western countries, there is a widespread tendency to stigmatize and discriminate people with mental illness in Asia. People with mental illness are considered as dangerous and aggressive which in turn increases the social distance. The role of supernatural, religious and magical approaches to mental illness is prevailing. The pathway to care is often shaped by scepticism towards mental health services and the treatments offered. Stigma experienced from family members is pervasive. Moreover, social disapproval and devaluation of families with mentally ill individuals are an important concern. This holds true particularly with regards to marriage, marital separation and divorce. Psychic symptoms, unlike somatic symptoms, are construed as socially disadvantageous. Thus, somatisation of psychiatric disorders is widespread in Asia. The most urgent problem of mental health care in Asia is the lack of personal and financial resources. Thus, mental health professionals are mostly located in urban areas. This increases the barriers to seek help and contributes to the stigmatization of the mentally ill. The attitude of mental health professionals towards people with mental illness is often stigmatizing. This review revealed that the stigmatization of people with mental illness is widespread in Asia. The features of stigmatization-beliefs about causes of and attitudes towards mental illness, consequences for help-seeking-have more commonalities than differences to Western countries.

    Extreme weather and climate-related events affect human health by causing death, injury, and illness, as well as having large socioeconomic impacts. Climate change has caused changes in extreme event frequency, intensity, and geographic distribution, and will continue to be a driver for change in the future. Some of these events include heat waves, droughts, wildfires, dust storms, flooding rains, coastal flooding, storm surges, and hurricanes. The pathways connecting extreme events to health outcomes and economic losses can be diverse and complex. The difficulty in predicting these relationships comes from the local societal and environmental factors that affect disease burden. More information is needed about the impacts of climate change on public health and economies to effectively plan for and adapt to climate change. This paper describes some of the ways extreme events are changing and provides examples of the potential impacts on human health and infrastructure. It also identifies key research gaps to be addressed to improve the resilience of public health to extreme events in the future.

    Prevention of sport injuries and illnesses is a focus for epidemiological surveillance. To record and analyse all sports injuries and illnesses registered during the second Asian Beach Games. A descriptive epidemiological study using the International Olympic Committee Surveillance system to register injuries and illnesses during the second Asian Beach Games. The second Asian Beach Games hosted 1132 athletes from 43 countries competing in 14 beach sports. All National Olympic Committees' physicians of the participating teams were invited to report all injuries and illnesses. In addition, medical officers at the different Olympic venues and the main Olympic village reported injuries and illnesses treated at the clinics on a daily basis. A total of 177 injuries were reported equating to an incidence rate of 156.4 per 1000 registered athletes. Tent pegging recorded the highest incidence of injuries with 357 per 1000 registered athletes. The most prevalent injuries were in the foot/toe with 14.1% of all reported injuries. The majority of injuries were incurred during competition (75.4%). In addition, the most common mechanism of injury was contact with another athlete (n=42, 23.7%) and combined sudden and gradual overuse contributed to 30% of the total injury burden. Furthermore, 118 illnesses were reported resulting in an incidence rate of 104.2 illnesses per 1000 registered athletes. The most affected system was the respiratory tract (39.1%) with infection being the most common cause (n=33, 38.0%). The incidence of injury and illness differed significantly among the 14 sports. The data indicate that the risk of injury from beach games is sport dependant. This means that any preventive measures have to be tailored for each discipline. Furthermore, the study showed that respiratory infections are the commonest illness in beach sports and therefore, event organisers should focus improving public health measures and hygiene awareness.

    1985-02-01

    Campylobacter laridis, a recently described thermophilic Campylobacter species found principally in seagulls, has not previously been linked to illness in humans. Six clinical isolates of this species were referred to the national campylobacter reference laboratory in 1982 and 1983. Each isolate was confirmed by biochemical characterization and by DNA relatedness studies. The six isolates were obtained during an illness: enteritis in four, severe crampy abdominal pain in one, and terminal bacteremia in an immunocompromised host in one. The infections occurred in persons 8 months to 71 years old. Neither the geographic distribution nor the reports of the patients suggest that seagulls played a direct role in the epidemiology of these infections. This potential human enteric pathogen appears to be clinically, epidemiologically, and microbiologically similar to Campylobacter jejuni and may be mistaken for it if nalidixic acid susceptibility screening is not routinely performed.

    In this paper I explore a seemingly mundane and inconsequential act--that of placing dolls and stuffed animals into newborns' incubator machines, in what I dub a kind of "teddy bear diplomacy," whereby mothers ornament their babies' high tech life-support prostheses with commonplace toys and trinkets. Using hospital ethnography and maternal interviews, I probe the psychodynamic significations of these ornamenting acts, which aspire to domesticate, animate and even humanize the incubator, itself a cyborg womb that displaces maternal purpose and problematizes bonding. The stress triggered by a high-risk infant and the double bind imposed by the therapeutic protocol lead me to here examine the intersubjectivity of illness in mothers' comorbidity and satellite syndromes. I argue that teddy bears and like artifacts serve as countertransitional objects to materially symbolize and perform the imagined mother-child dyad. Moreover, as autopoetic devices in the metamorphosis of maternal identity, they may empower a mother's vicarious participation in her child's healing, and thereby work towards closure of her own intersubjective afflictions.

    Daya Bay Nuclear Power Plant is put into commercial operation in 1994 Until 1996, there are 368 human error events in operating and maintenance area, occupying 39% of total events. These events occurred mainly in the processes of maintenance, test equipment isolation and system on-line, in particular in refuelling and maintenance. The author analyses root causes for human errorievents, which are mainly operator omission or error procedure deficiency; procedure not followed; lack of training; communication failures; work management inadequacy. The protective measures and treatment principle for human error events are also discussed, and several examples applying them are given. Finally, it is put forward that key to prevent human error event lies in the coordination and management, person in charge of work, and good work habits of staffs

    Influenza-like-illness can be caused by a wide range of respiratory viruses. The etiology of influenza-like-illness in developing countries such as Papua New Guinea is poorly understood. The etiological agents associated with influenza-like-illness were investigated retrospectively for 300 nasopharyngeal swabs received by the Papua New Guinea National Influenza Centre in 2010. Real-time PCR/RT-PCR methods were used for the detection of 13 respiratory viruses. Patients with influenza-like-illness were identified according to the World Health Organization case definition: sudden onset of fever (>38°C), with cough and/or sore throat, in the absence of other diagnoses. At least one viral respiratory pathogen was detected in 66.3% of the samples tested. Rhinoviruses (17.0%), influenza A (16.7%), and influenza B (12.7%) were the pathogens detected most frequently. Children 5 years of age. Influenza B, adenovirus, and respiratory syncytial virus were all detected at significantly higher rates in children Papua New Guinea. © 2013 Wiley Periodicals, Inc.

  16. Ethnomedical treatment of children's diarrheal illnesses in the highlands of Ecuador.

    McKee, L

    1987-01-01

    In rural communities in the Ecuadorian Highlands, gastrointestinal disease is the leading cause of death. This paper proposes a model of the world view that specifies the factors that condition illness or health and a traditional taxonomy that relies on certain criteria to categorize three classes of diarrhea. These determine whether ethnomedical or medical treatment will be used to 'cure' a child. The three illness classes: diarrhea produced by supernatural forces, by humoral imbalances, and by 'infection' differ etiologically. The ambient air and its temperatures, the constitution, humoral state and overt personality characteristics (character) of the individual, and the predelictions of the evil spirits that seek to sap their vital essence all figure in the origins of illness. The model of the world view is related to a folk taxonomy, which, it is asserted, provides a charter for families' responses to child illness, that more often than not, are appropriate under the economic conditions they suffer.

    A toxin variant strain of Clostridium difficile was isolated from two patients with C. difficile-associated disease (CDAD), one of whom died from extensive pseudomembranous colitis. This strain, identified by restriction endonuclease analysis (REA) as type CF2, was not detected by an immunoassay for C. difficile toxin A. Culture supernatants of CF2 failed to elicit significant enterotoxic activity in the rabbit ileal loop assay but did produce atypical cytopathic effects in cell culture assay. Southern hybridization, PCR amplification, and DNA sequence analyses were performed on the toxin A (tcdA) and toxin B (tcdB) genes of type CF2 isolate 5340. Type CF2 5340 tcdA exhibited a 1,821-bp truncation, due to three deletions in the 3′ end of the gene, and a point mutation in the 5′ end of the gene, resulting in a premature stop codon at tcdA position 139. Type CF2 5340 tcdB exhibited multiple nucleotide base substitutions in the 5′ end of the gene compared to tcdB of the standard toxigenic strain VPI 10463. Type CF2 5340 toxin gene nucleotide sequences and deduced amino acid sequences showed a strong resemblance to those of the previously described variant C. difficile strain 1470, a strain reported to have reduced pathogenicity and no association with clinical illness in humans. REA of strain 1470 identified this strain as a distinct type (CF1) within the same REA group as the closely related type CF2. A review of our clinical-isolate collection identified five additional patients infected with type CF2, three of whom had documented CDAD. PCR amplification of the 3′ end of tcdA demonstrated identical 1.8-kb deletions in all seven type CF2 isolates. REA type CF2 is a toxin variant strain of C. difficile that retains the ability to cause disease in humans but is not detected in clinical immunoassays for toxin A. PMID:10992443

    2015-06-01

    Exertional heat illness is a classification of disease with clinical presentations that are not always diagnosed easily. Exertional heat stroke is a significant cause of death in competitive sports, and the increasing popularity of marathons races and ultra-endurance competitions will make treating many heat illnesses more common for Emergency Medical Services (EMS) providers. Although evidence is available primarily from case series and healthy volunteer studies, the consensus for treating exertional heat illness, coupled with altered mental status, is whole body rapid cooling. Cold or ice water immersion remains the most effective treatment to achieve this goal. External thermometry is unreliable in the context of heat stress and direct internal temperature measurement by rectal or esophageal probes must be used when diagnosing heat illness and during cooling. With rapid recognition and implementation of effective cooling, most patients suffering from exertional heat stroke will recover quickly and can be discharged home with instructions to rest and to avoid heat stress and exercise for a minimum of 48 hours; although, further research pertaining to return to activity is warranted.

    Full Text Available Data about burden of influenza in pregnancy in India are scant. In order to assess the contribution of influenza to acute respiratory illness (ARI in pregnancy, 266 north Indian pregnant females with febrile ARI were studied from December 2014 to May 2015. Twin nasopharyngeal/oropharyngeal swabs were obtained and tested for influenza viruses by RT-PCR. Fifty (18.8% patients tested positive for influenza (A/H1N1pdm09 in 41, A/H3N2 in 8, and influenza B Yamagata in 1. Rigors, headache, and a family history of ARI were significantly more frequent in influenza positive patients. Oseltamivir and supportive therapy were administered to all confirmed cases. Nine influenza positive cases needed hospitalization for their respiratory illness, and 5 developed respiratory failure. Of these, 4 (3 in third trimester succumbed to their illness. We conclude that influenza viruses are a cause of significant morbidity and mortality among pregnant females with ARI in north India. As such, appropriate preventive strategies of influenza vaccination and early initiation of antiviral therapy during illness are stressed.

    Some immigrant populations, for instance, Turkish immigrants, suffer from worse mental health than the general population. Moreover, psychotherapeutic treatment does not work well in this group. This might be explained by lower motivation for psychotherapy and particular illness beliefs as important early predictors of treatment outcome. We investigate differences in these predictors between Turkish immigrant inpatients and inpatients without a migration background and evaluate whether particular illness beliefs have a negative impact on motivation for psychotherapy. Turkish immigrant inpatients and inpatients without a migration background (N = 100), suffering from depressive disorder, somatoform disorder, and/or adjustment disorder, completed questionnaires assessing motivation for psychotherapy, depressive and somatic symptoms, illness perception, illness-related locus of control, and causal illness attributions. Despite a higher symptom burden, motivation for psychotherapy was lower in Turkish immigrant inpatients than in inpatients without a migration background (d = 0.54). This was fully explained by stronger beliefs in supernatural causes of illness and higher fatalistic-external illness-related locus of control in the Turkish immigrant sample (mediation analysis; R (2) = 0.27). Turkish immigrants believe in supernatural or fatalistic causes of illness and fatalistic-external locus of control to a greater extent than German inpatients without a migration background. These beliefs reduce motivation for psychotherapy and need to be addressed in psychotherapeutic treatment in order to secure positive treatment outcomes.

    Objectives To assess community perceptions of mental illness in the Bwindi Community Hospital (BCH) catchment area: to recognise beliefs about the causes and the treatments for mental illness. To provide community data to staff at BCH as they work to develop more effective community mental health programmes. Background A shortage of mental health providers in Uganda has prompted research into community-based task-sharing models for the provision of mental health services in underserved communities. Methods Six focus group discussions, with a total of 54 community members (50% male, n = 27; mean age + s.d. [39.9 + 10.9 years]) from the BCH catchment area, were conducted to assess community member and stakeholder perceptions of mental illness and belief in the feasibility of community-based programming. Qualitative study of data through thematic analysis was conducted to assess the presence of commonly occurring perceptions. Results Qualitative thematic analysis revealed two major themes: (1) belief that any given patient’s metal illness results from either an intrinsic or an extrinsic cause and (2) belief in a need to determine treatment of mental illness based on the believed cause. Conclusion As BCH designs community-based mental health services, our findings provide support for the need for further education of community members and training of community health workers to address and integrate the above-stated beliefs regarding mental illness.

    We examine whether reporting on violent and terrorist acts committed in July 2016 by persons who, among other characteristics, were suspected to have mental health issues did impact on mental illness stigma, and whether any changes added to changes observed after the Germanwings plane crash in 2015. Three identical online surveys (in 2014, 2015 and 2016) were conducted among persons >15 years old from an established market research panel in Germany (N=2195). Participants answered questions about a woman ("Anne") with either depression or schizophrenia as described in an unlabeled vignette. In the 2016 survey (<4 weeks after the attacks), we also elicited perceived causes of the violent incidents. Compared to 2014, the predicted probability to rate Anne as dangerous increased from 7% to 11%. Perceived unpredictability increased from 17% to 23%. Other stigma measures did not change significantly. No significant changes were visible between 2015 and 2016. Mental illness ranked third among the most important perceived causes for the attacks in 2016, after 'religious beliefs' and 'being manipulated by others'. Overall, the observed attitude changes were small. We discuss how the context of the attacks may have prevented further attitude change regarding persons with mental illness.

    Heilferty, Catherine McGeehin

    2009-07-01

    This paper is a report of a concept analysis of illness blogs and their relevance to nursing research on communication during illness. Blogs are being used by patients and family members to describe the experience of illness, but very little is known about this phenomenon. Seventeen English language databases and one Internet search engine were searched from 1990 to 2007 using the truncated term 'blog*'. Specific illness terms together with 'blog*', for example, blog* and diabetes; and blog* and cancer, were used to expand the search. Reports were included if they were of qualitative or quantitative research that included a definition of blogs or blogging and some identification or description of blog uses pertinent to the discipline. Specific emphasis was placed on blog use by individuals coping with illness experiences. 'Meta' writings by authors about their own blogging intentions and experiences were excluded. An illness blog is the online expression of the narrative of illness. Theoretical and operational definitions, defining attributes, uses, antecedents and consequences were developed. The literature search returned 45 works from 17 disciplines referring to the definition and uses of blogging. Support is offered from the review of literature and analysis of the concept for the development of a theory of online communication during illness. Reading and incorporating illness blogs into care will enhance patient-provider relationships. Analysis of the narratives being created online about the illness experience will contribute significantly to nursing's body of knowledge.

    The environment and dietary factors play an essential role in the etiology of cancer. Environmental component is implicated in ~80 % of all cancers; however, the causes for certain cancers are still unknown. The potential players associated with various cancers include chemicals, heavy metals, diet, radiation, and smoking. Lifestyle habits such as smoking and alcohol consumption, exposure to certain chemicals (e.g., polycyclic aromatic hydrocarbons, organochlorines), metals and pesticides also pose risk in causing human cancers. Several studies indicated a strong association of lung cancer with the exposure to tobacco products and asbestos. The contribution of excessive sunlight, radiation, occupational exposure (e.g., painting, coal, and certain metals) is also well established in cancer. Smoking, excessive alcohol intake, consumption of an unhealthy diet, and lack of physical activity can act as risk factors for cancer and also impact the prognosis. Even though the environmental disposition is linked to cancer, the level and duration of carcinogen-exposure and associated cellular and biochemical aspects determine the actual risk. Modulations in metabolism and DNA adduct formation are considered central mechanisms in environmental carcinogenesis. This review describes the major environmental contributors in causing cancer with an emphasis on molecular aspects associated with environmental disposition in carcinogenesis.

    Human parechovirus types 1-16 (HPeV1-16) are positive strand RNA viruses in the family Picornaviridae. We investigated a 2015 outbreak of HPeV3 causing illness in infants in Victoria, Australia. Virus genome was extracted from clinical material and isolates and sequenced using a combination of next generation and Sanger sequencing. The HPeV3 outbreak genome was 98.7% similar to the HPeV3 Yamagata 2011 lineage for the region encoding the structural proteins up to nucleotide position 3115, but downstream of that the genome varied from known HPeV sequences with a similarity of 85% or less. Analysis indicated that recombination had occurred, may have involved multiple types of HPeV and that the recombination event/s occurred between March 2012 and November 2013. However the origin of the genome downstream of the recombination site is unknown. Overall, the capsid of this virus is highly conserved, but recombination provided a different non-structural protein coding region that may convey an evolutionary advantage. The indication that the capsid encoding region is highly conserved at the amino acid level may be helpful in directing energy towards the development of a preventive vaccine for expecting mothers or antibody treatment of young infants with severe disease.

  9. Five dramas of illness.

    Science.gov (United States)

    Frank, Arthur W

    2007-01-01

    First-person narratives of illness experience are dramatic: the narrator, who is also the sufferer, is caught in conflicts of forces that permit understanding more than control. Among the dramas of illness, five occur frequently in autobiographical accounts of illness. These dramas overlap and have varying emphases in different people's stories. They are the drama of genesis (what instigated the illness); the drama of emotion work (what emotional displays are required or prohibited); the drama of fear and loss; the drama of meaning; and finally, the drama of self. This five-drama framework can focus critical and clinical attention on which conflicting forces the ill person is working to reconcile, what makes that work difficult, and how conceiving of one's illness as a drama can be a source of meaning and value.

Our second purpose was to differentiate MD from Delusions of Parasitosis (DP, another "informal" label that fit most of our MD patients. How we defined and how we treated these patients depended literally on factual data that would determine outcome. How they were labeled in one sense was irrelevant, except for the confusing conflict rampant in the medical community, possibly significantly skewing treatment outcomes. Case presentation Clinical information was collected from 25 of 30 consecutive self-defined patients with Morgellons disease consisting of laboratory data, medical history and physical examination findings. Abnormalities were quantified and grouped by system, then compared and summarized, but the numbers were too small for more complex mathematical analysis. The quantification of physical and laboratory abnormalities allowed at least the creation of a practical clinical boundary, separating probable Morgellons from non-Morgellons patients. All the 25 patients studied meet the most commonly used DP definitions. Conclusions These data suggest Morgellons disease can be characterized as a physical human illness with an often-related delusional component in adults. All medical histories support that behavioral aberrancies onset only after physical symptoms. The identified abnormalities include both immune deficiency and chronic inflammatory markers that

  13. Radiation in relation to mutation rate, mutational damage and human ill-health

    The effect of radiation in increasing the frequency of gene mutations is now reasonably understood. We discuss first how an increase in the mutation rate is reflected in the mutational damage expressed in populations. It is shown that the mutational damage, assessed by the loss of fitness in a population or the number of eventual gene extinctions, is equal to the number of new mutations arising per generation or the mutation rate. In a population of stable size, a dose of 1 rem given to 10 6 people leads to roughly 600 gene extinctions when summed over all ensuing generations if the dose is applied to only one generation; this number of extinctions will occur in each succeeding generation if the dose is given to every generation. However, the concept of genetic extinction, although quantifiable, is of limited value in assessing radiation risks since its impact on human ill-health is very speculative. In particular, no estimate can be made of the total cost of effects which are minor in each individual in which they arise, but which, because they are so minor, persist in the population for many generations. The best current estimate is for 14-140 obvious defects in the first few generations following exposure of 10 6 people to a dose of 1 rem. (auth.)

    Biomarkers of all-cause mortality are of tremendous clinical and research interest. Because of the long potential duration of prospective human lifespan studies, such biomarkers can play a key role in quantifying human aging and quickly evaluating any potential therapies. Decades of research into mortality biomarkers have resulted in numerous associations documented across hundreds of publications. Here, we present MortalityPredictors.org , a manually-curated, publicly accessible database, housing published, statistically-significant relationships between biomarkers and all-cause mortality in population-based or generally healthy samples. To gather the information for this database, we searched PubMed for appropriate research papers and then manually curated relevant data from each paper. We manually curated 1,576 biomarker associations, involving 471 distinct biomarkers. Biomarkers ranged in type from hematologic (red blood cell distribution width) to molecular (DNA methylation changes) to physical (grip strength). Via the web interface, the resulting data can be easily browsed, searched, and downloaded for further analysis. MortalityPredictors.org provides comprehensive results on published biomarkers of human all-cause mortality that can be used to compare biomarkers, facilitate meta-analysis, assist with the experimental design of aging studies, and serve as a central resource for analysis. We hope that it will facilitate future research into human mortality and aging.

    Purpose Elevated intraocular pressure (IOP) is a major risk factor for glaucoma. One consequence of raised IOP is that ocular tissues are subjected to increased hydrostatic pressure (HP). The effect of raised HP on stress pathway signaling and retinal ganglion cell (RGC) survival in the human retina was investigated. Methods A chamber was designed to expose cells to increased HP (constant and fluctuating). Accurate pressure control (10-100mmHg) was achieved using mass flow controllers. Human organotypic retinal cultures (HORCs) from donor eyes (pressure for 24 or 48h caused no loss of structural integrity, LDH release, decrease in RGC marker expression (THY-1) or loss of RGCs compared with controls. In addition, there was no increase in TUNEL-positive NeuN-labelled cells at either time-point indicating no increase in apoptosis of RGCs. OGD increased apoptosis, reduced RGC marker expression and RGC number and caused elevated LDH release at 24h. p38 and JNK phosphorylation remained unchanged in HORCs exposed to fluctuating pressure (10-100mmHg; 1 cycle/min) for 15, 30, 60 and 90min durations, whereas OGD (3h) increased activation of p38 and JNK, remaining elevated for 90min post-OGD. Conclusions Directly applied HP had no detectable impact on RGC survival and stress-signalling in HORCs. Simulated ischemia, however, activated stress pathways and caused RGC death. These results show that direct HP does not cause degeneration of RGCs in the ex vivo human retina. PMID:25635827

    Viruses detected in patients with acute respiratory infections may be the cause of illness or asymptomatic shedding. To estimate the attributable fraction (AF) and the detection rate attributable to illness for each of the different respiratory viruses We compared the prevalence of 10 common respiratory viruses (influenza A and B viruses, parainfluenza virus 1-3; respiratory syncytial virus (RSV); adenovirus, rhinovirus, human metapneumovirus (hMPV) and enterovirus) in both HIV positive and negative patients hospitalized with severe acute respiratory illness (SARI), outpatients with influenza-like illness (ILI), and control subjects who did not report any febrile, respiratory or gastrointestinal illness during 2012-2015 in South Africa. We enrolled 1959 SARI, 3784 ILI and 1793 controls with a HIV sero-prevalence of 26%, 30% and 43%, respectively. Influenza virus (AF: 86.3%; 95%CI: 77.7-91.6%), hMPV (AF: 85.6%; 95%CI: 72.0-92.6%), and RSV (AF: 83.7%; 95%CI: 77.5-88.2%) infections were associated with severe disease., while rhinovirus (AF: 46.9%; 95%CI: 37.6-56.5%) and adenovirus (AF: 36.4%; 95%CI: 20.6-49.0%) were only moderately associated. Influenza, RSV and hMPV can be considered pathogens if detected in ILI and SARI while rhinovirus and adenovirus were commonly identified in controls suggesting that they may cause only a proportion of clinical disease observed in positive patients. Nonetheless, they may be important contributors to disease. Copyright © 2015 Elsevier B.V. All rights reserved.

    Cross-cultural studies indicate that every culture has its own particular explanations for health and illness and its own healing strategies. The Konso people have always practiced indigenous medicine and have multifaceted accounts or multiple dimensions of illness perceptions and health-care beliefs and practices. This paper describes how perceptions of health and illness are instrumental in health and treatment outcomes among the Konso people in southwestern Ethiopia. Results may provide an understanding of the perceptions of health and illness in relation to the local cosmology, religion, and environment. The ethnographic method was employed to generate evidence, complemented by focus group discussions, in-depth interviews, and direct observation. Thematic analysis was employed to categorize and interpret the data. Findings indicate that the Konso people's worldview, particularly as it relates to health, illness, and healing systems, is closely linked to their day-to-day lives. Older people believe illnesses are caused by a range of supernatural forces, including the wrath of God or local gods, oritta (spirit possession), and karayitta (ancestral spirits), and they use culturally prescribed treatment. Young and formally educated members of the community attribute causes of diseases to germitta (germs) and factorta (bacteria) and tend to seek treatment mostly in modern health facilities. Perceptions of health and illness as well as of healing are part of Konso people's worldview. Local communities comprehend health problems and solutions within their cultural frame of reference, which has changed over the years. The Konso people associate their health situations with socio-cultural and religious factors. The individual's behavior and interactions with the social, natural, and supernatural powers affect the well-being of the whole group. The individual, the family, the clan leaders, and the deceased are intimately linked to one's culturally based health beliefs

    Within the United States, elevated levels of fecal indicator bacteria (FIB) remain the leading cause of surface water-quality impairments requiring formal remediation plans under the federal Clean Water Act's Total Maximum Daily Load (TMDL) program. The sufficiency of compliance with numerical FIB criteria as the targeted endpoint of TMDL remediation plans may be questionable given poor correlations between FIB and pathogenic microorganisms and varying degrees of risk associated with exposure to different fecal pollution sources (e.g. human vs animal). The present study linked a watershed-scale FIB fate and transport model with a dose-response model to continuously predict human health risks via quantitative microbial risk assessment (QMRA), for comparison to regulatory benchmarks. This process permitted comparison of risks associated with different fecal pollution sources in an impaired urban watershed in order to identify remediation priorities. Results indicate that total human illness risks were consistently higher than the regulatory benchmark of 36 illnesses/1000 people for the study watershed, even when the predicted FIB levels were in compliance with the Escherichia coli geometric mean standard of 126 CFU/100 mL. Sanitary sewer overflows were associated with the greatest risk of illness. This is of particular concern, given increasing indications that sewer leakage is ubiquitous in urban areas, yet not typically fully accounted for during TMDL development. Uncertainty analysis suggested the accuracy of risk estimates would be improved by more detailed knowledge of site-specific pathogen presence and densities. While previous applications of the QMRA process to impaired waterways have mostly focused on single storm events or hypothetical situations, the continuous modeling framework presented in this study could be integrated into long-term water quality management planning, especially the United States' TMDL program, providing greater clarity to

    Gun violence and mental illness is a major area of media attention, especially because highly publicized mass shootings seem to have become more commonly reported in the press. Gun access also is undergoing a highly politicized debate in the United States. It is important for mental health practitioners to understand the background and context of laws related to firearms access, and to understand data related to risk of suicide and violence toward others caused by gun violence among persons with mental illness. In addition, clinically driven risk assessments with specific inquiry related to firearms can be important for identifying individuals for whom firearm-focused clinical risk mitigation may be warranted.

    2005-04-01

    Poverty is not solely a social or political matter, nor is it caused simply by population pressures as Thomas Malthus postulated in 1798. A new understanding of poverty is emerging in which natural and environmental drivers, together with social, political, and demographic causes, underpin livelihoods. The Earth sciences, therefore, play a critical role in identifying the deep causes of human suffering and in identifying solutions. The State of the Planet: Why Are So Many So Poor? For far too many, the state of human well-being is bleak. Around one in six human beings-1 billion people-live in extreme poverty, struggling to survive on less than $1 a day; another one sixth of humanity ekes out existence on $2 per day (U.N. Development Programme (UNDP) Human Development Report, 2004; http://hdr.undp.org/2004/). The extreme poor lack all normal attributes of a decent, dignified life: adequate food, housing, sanitation, health care, education, and employment. Some 800 million people lack sufficient nourishment almost every day. It stunts their mental and physical development and shortens their lives, making them susceptible to common illnesses that attack their hunger-weakened bodies. Poor nutrition in mothers and infants is the leading cause of reduced disability-adjusted life years in poor countries [ Economist, 2004].

    Stigma in relation to mental illness is one of the main factors inhibiting people from seeking help. Studies have been undertaken looking into the knowledge, attitudes, and beliefs (KAB) about mental illness among residents in Qatar; however, none have looked specifically at students in higher education. The aim of this study was to understand the KAB toward mental illness among students at a Qatari university and determine if there are any differences based on gender, nationality, and college type. A convenience sample of students from all genders, colleges, and nationalities was approached to participate in a survey that consisted of four sections: demographic, beliefs, attitudes, and help-seeking and treatment preferences associated with mental illness. Chi-square testing was performed to test for differences in the distribution of proportions of our primary outcomes (students' beliefs, attitudes, and help-seeking and treatment preferences). A total of 282 students completed the survey. The majority of the participating students were females (59.3%), non-Qataris (64.3%), and enrolled in science-based colleges (62.7%). Beliefs reflecting poor mental health literacy, such as "medications to treat mental illness can cause addiction", "mental illness is not like any other illness", or that "mental illness is a punishment from God", were reported by a majority of students (84.4%, 56.7%, and 50.2%, respectively). Stigmatizing attitudes that were endorsed by a majority of students included believing that people with mental illness cannot have regular jobs (60.2%), that people with mental illness are dangerous (65.7%), and that they would not marry someone with a mental illness (88.9%). Additionally, 33.6% of students indicated they would be ashamed to mention if someone in their family or they themself, had a mental illness. A vast majority of students (86.3%) indicated to prefer family and friend's support as treatment options. Significant differences in KAB about

    We investigated the persistence of viable Orientia tsutsugamushi in patients who had recovered from scrub typhus. Blood specimens were available from six patients with scrub typhus who were at 1 to 18 months after the onset of the illness. The EDTA-treated blood specimens were inoculated into ECV304 cells, and cultures were maintained for 7 months. Sequencing of the 56-kDa type-specific antigen gene of O. tsutsugamushi was performed to ascertain the homology of isolates. O. tsutsugamushi was isolated from all six patients, and nucleotide sequences of isolates serially collected from each patient were identical in all five patients in whom nucleotide sequences were compared. One patient relapsed 2 days after completion of antibiotic therapy; two patients complained of weakness for 1 to 2.5 months after the illness; one patient underwent coronary angioplasty 6 months later; and one patient suffered from a transient ischemic attack 8 months later. This finding suggests that O. tsutsugamushi causes chronic latent infection, which may be associated with certain clinical illnesses, preceded by scrub typhus. Antibiotic therapy abates the symptoms of scrub typhus, but does not eradicate O. tsutsugamushi from the human body.

    Clinicians may be asked whether mental ill-health has been caused by work but there is no guidance on how this judgement should be made. To seek a consensus on the factors that should be considered and how they should be sought when attributing mental ill-health to work. A three-round Delphi study involving expert academics, occupational physicians, psychiatrists and psychologists. We deemed consensus had been reached when 66% or more of the experts were in agreement. Of 54 invited experts, 35 (65%) took part in the first round, 30 of these 35 (86%) in the second and 29 of these 30 (97%) in the final round. Consensus was reached for 11 workplace stressors: high job strain; effort-reward imbalance; major trauma; interpersonal conflict; inadequate support; role ambiguity; person-job mismatch; organizational injustice; organizational culture; work scheduling and threats to job security. Seven personal factors were identified as being important: previous mental illness; personality traits of neuroticism; adverse life events or social circumstances; resilience; a family history of mental illness and secondary gain. The worker, manager and co-workers were thought to be the most useful sources of workplace information. Consensus was reached for a definition of occupational mental illness but not for a threshold of work-relatedness. The attribution of mental ill-health to work is complex and involves the consideration of both workplace stressors and personal factors of vulnerability. Clinical consultation with an occupational physician who is familiar with the workplace is central to the process. © The Author 2015.

    The human roseoloviruses human herpesvirus 6A (HHV-6A), HHV-6B, and HHV-7 comprise the Roseolovirus genus of the human Betaherpesvirinae subfamily. Infections with these viruses have been implicated in many diseases; however, it has been challenging to establish infections with roseoloviruses as direct drivers of pathology, because they are nearly ubiquitous and display species-specific tropism. Furthermore, controlled study of infection has been hampered by the lack of experimental models, and until now, a mouse roseolovirus has not been identified. Herein we describe a virus that causes severe thymic necrosis in neonatal mice, characterized by a loss of CD4 + T cells. These phenotypes resemble those caused by the previously described mouse thymic virus (MTV), a putative herpesvirus that has not been molecularly characterized. By next-generation sequencing of infected tissue homogenates, we assembled a contiguous 174-kb genome sequence containing 128 unique predicted open reading frames (ORFs), many of which were most closely related to herpesvirus genes. Moreover, the structure of the virus genome and phylogenetic analysis of multiple genes strongly suggested that this virus is a betaherpesvirus more closely related to the roseoloviruses, HHV-6A, HHV-6B, and HHV-7, than to another murine betaherpesvirus, mouse cytomegalovirus (MCMV). As such, we have named this virus murine roseolovirus (MRV) because these data strongly suggest that MRV is a mouse homolog of HHV-6A, HHV-6B, and HHV-7. IMPORTANCE Herein we describe the complete genome sequence of a novel murine herpesvirus. By sequence and phylogenetic analyses, we show that it is a betaherpesvirus most closely related to the roseoloviruses, human herpesviruses 6A, 6B, and 7. These data combined with physiological similarities with human roseoloviruses collectively suggest that this virus is a murine roseolovirus (MRV), the first definitively described rodent roseolovirus, to our knowledge.

  10. The cost of community-managed viral respiratory illnesses in a cohort of healthy preschool-aged children

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Abstract Background Acute respiratory illnesses (ARIs during childhood are often caused by respiratory viruses, result in significant morbidity, and have associated costs for families and society. Despite their ubiquity, there is a lack of interdisciplinary epidemiologic and economic research that has collected primary impact data, particularly associated with indirect costs, from families during ARIs in children. Methods We conducted a 12-month cohort study in 234 preschool children with impact diary recording and PCR testing of nose-throat swabs for viruses during an ARI. We used applied values to estimate a virus-specific mean cost of ARIs. Results Impact diaries were available for 72% (523/725 of community-managed illnesses between January 2003 and January 2004. The mean cost of ARIs was AU$309 (95% confidence interval $263 to $354. Influenza illnesses had a mean cost of $904, compared with RSV, $304, the next most expensive single-virus illness, although confidence intervals overlapped. Mean carer time away from usual activity per day was two hours for influenza ARIs and between 30 and 45 minutes for all other ARI categories. Conclusion From a societal perspective, community-managed ARIs are a significant cost burden on families and society. The point estimate of the mean cost of community-managed influenza illnesses in healthy preschool aged children is three times greater than those illnesses caused by RSV and other respiratory viruses. Indirect costs, particularly carer time away from usual activity, are the key cost drivers for ARIs in children. The use of parent-collected specimens may enhance ARI surveillance and reduce any potential Hawthorne effect caused by compliance with study procedures. These findings reinforce the need for further integrated epidemiologic and economic research of ARIs in children to allow for comprehensive cost-effectiveness assessments of preventive and therapeutic options.

    We examined African American women's representations/beliefs about mental illness, preferred coping behaviors if faced with mental illness, whether perceived stigma was associated with treatment-seeking, and if so, whether it was related to beliefs and coping preference, and whether these variables differed by age group. Participants were 185 community-dwelling African American women 25 to 85 years of age. Results indicated the women believed that mental illness is caused by several factors, including family-related stress and social stress due to racism, is cyclical, and has serious consequences but can be controlled by treatment. Participants endorsed low perceptions of stigma. Major preferred coping strategies included praying and seeking medical and mental health care. Age differences were found in all variables except stigma.

    Many psychiatric illnesses are associated with early mortality and with an increased risk of developing physical diseases that are more typically seen in the elderly. Moreover, certain psychiatric illnesses may be associated with accelerated cellular aging, evidenced by shortened leukocyte telomere length (LTL), which could underlie this association. Shortened LTL reflects a cell's mitotic history and cumulative exposure to inflammation and oxidation as well as the availability of telomerase, a telomere-lengthening enzyme. Critically short telomeres can cause cells to undergo senescence, apoptosis or genomic instability, and shorter LTL correlates with poorer health and predicts mortality. Emerging data suggest that LTL may be reduced in certain psychiatric illnesses, perhaps in proportion to exposure to the psychiatric illnesses, although conflicting data exist. Telomerase has been less well characterized in psychiatric illnesses, but a role in depression and in antidepressant and neurotrophic effects has been suggested by preclinical and clinical studies. In this article, studies on LTL and telomerase activity in psychiatric illnesses are critically reviewed, potential mediators are discussed, and future directions are suggested. A deeper understanding of cellular aging in psychiatric illnesses could lead to re-conceptualizing them as systemic illnesses with manifestations inside and outside the brain and could identify new treatment targets.

    Glycaemic control is recognized as one of the important aspects in managing critically ill patients. Both hyperglycaemia and hypoglycaemia independently increase the risk of patient mortality. Hence, the identification of optimal glycaemic control is of paramount importance in the management of critically ill patients. The aim of this literature review is to examine the current status of glycaemic control in critically ill adult patients. This literature review will focus on randomized controlled trials comparing intensive insulin therapy to conventional insulin therapy, with an objective to identify optimal blood glucose level targets for critically ill adult patients. A literature review was conducted to identify large randomized controlled trials for the optimal targeted blood glucose level for critically ill adult patients published since 2000. A total of eight studies fulfilled the selection criteria of this review. With current human and technology resources, the results of the studies support commencing glycaemic control once the blood glucose level of critically ill patients reaches 10 mmol/L and maintaining this level between 8 mmol/L and 10 mmol/L. This literature review provides a recommendation for targeting the optimal blood glucose level for critically ill patients within moderate blood glucose level target range (8-10 mmol/L). The need for uniformed glucometrics for unbiased reporting and further research for optimal blood glucose target is required, especially in light of new technological advancements in closed-loop insulin delivery and monitoring devices. This literature review has revealed a need to call for consensus in the measurement and reporting of glycaemic control using standardized glucometrics. © 2017 British Association of Critical Care Nurses.

    Streptococcus agalactiae causes both symptomatic cystitis and asymptomatic bacteriuria (ABU); however, growth characteristics of S. agalactiae in human urine have not previously been reported. Here, we describe a phenotype of robust growth in human urine observed in ABU-causing S. agalactiae (ABSA) that was not seen among uropathogenic S. agalactiae (UPSA) strains isolated from patients with acute cystitis. In direct competition assays using pooled human urine inoculated with equal numbers of a prototype ABSA strain, designated ABSA 1014, and any one of several UPSA strains, measurement of the percentage of each strain recovered over time showed a markedly superior fitness of ABSA 1014 for urine growth. Comparative phenotype profiling of ABSA 1014 and UPSA strain 807, isolated from a patient with acute cystitis, using metabolic arrays of >2,500 substrates and conditions revealed unique and specific l-malic acid catabolism in ABSA 1014 that was absent in UPSA 807. Whole-genome sequencing also revealed divergence in malic enzyme-encoding genes between the strains predicted to impact the activity of the malate metabolic pathway. Comparative growth assays in urine comparing wild-type ABSA and gene-deficient mutants that were functionally inactivated for the malic enzyme metabolic pathway by targeted disruption of the maeE or maeK gene in ABSA demonstrated attenuated growth of the mutants in normal human urine as well as synthetic human urine containing malic acid. We conclude that some S. agalactiae strains can grow in human urine, and this relates in part to malic acid metabolism, which may affect the persistence or progression of S. agalactiae ABU.

    Despite the fact that mental illness is a common problem in society, people's perception of the mentally ill and community attitude towards them is still rather poor, making their rehabilitation and reintegration into society an uphill task. To examine the stigmatization of people with mental illness within a rural community and identify the socio-demographic variables involved. A cross-sectional descriptive study using a multi-stage random sampling technique to obtain data through an interviewer-administered questionnaire to 325 adult inhabitants of a rural community in Nigeria. The results showed widespread ignorance about causation, mode of transmission and remedies available for mental illness, with only 0.9% of respondents attributing mental illness to brain disease. The others attributed it to spiritual attack, punishment for evil doing and illicit psychoactive substance use, among other things. Negative views about the mentally ill were also widely expressed resulting in discriminatory practices. Stigmatization of people with mental illness is still rampant in our community. There is a need for adequate public education about the causes and mode of transmission of mental illness and the treatment options available in the community.

    The effects of mental health nurses' own experience of mental illness or being a carer have rarely been researched beyond the workplace setting. This study aimed to explore how the experience of mental illness affects mental health nurses' lives outside of and inside work. A sample of 26 mental health nurses with personal experience of mental illness took part in semistructured interviews. Data were analysed thematically using a six-phase approach. The analysis revealed the broad context of nurses' experiences of mental illness according to three interwoven themes: mental illness as part of family life; experience of accessing services; and life interwoven with mental illness. Participants typically described personal and familial experience of mental illness across their life course, with multiple causes and consequences. The findings suggest that nurses' lives outside of work should be taken into account when considering the impact of their personal experience of mental illness. Similarly being a nurse influences how mental illness is experienced. Treatment of nurses with mental illness should account for their nursing expertise whilst recognizing that the context for nurses' mental illness could be much broader than the effect of workplace stress. © 2018 Australian College of Mental Health Nurses Inc.

    Incorporating individuals' understandings and explanations of mental illness into service delivery offers benefits relating to increased service relevance and meaning. Existing research delineates explanatory models of mental illness held by individuals in home, outpatient, and hospital-based contexts; research on models held by those in peer-support contexts is notably absent. In this article, I describe themes identified within and across explanatory models of mental illness and recovery held by mental health consumers (N = 24) at one peer center, referred to as a consumer-operated service center (COSP). Participants held explanatory models inclusive of both developmental stressors and biomedical causes, consistent with a stress-diathesis model (although no participant explicitly referenced such). Explicit incorporation of stress-diathesis constructs into programming at this COSP offers the potential of increasing service meaning and relevance. Identifying and incorporating shared meanings across individuals' understandings of mental illness likewise can increase relevance and meaning for particular subgroups of service users. © The Author(s) 2014.

  20. Microbiological diagnosis of infections caused by Campylobacter jejuni and Campylobacter coli in humans

    Directory of Open Access Journals (Sweden)

    Natalia Rokosz

    2014-01-01

    Full Text Available Campylobacter jejuni and Campylobacter coli are Gram-negative, microaerophilic bacteria which are worldwide in distribution, causing a zoonotic disease in humans called campylobacteriosis. These infections are mainly caused by eating contaminated food products, most often improperly prepared poultry meat. Campylobacteriosis usually takes the form of gastroenteritis, or inflammation of the intestines, and the characteristic symptoms are watery-mucous diarrhea often with the presence of blood in stool, nausea, vomiting, abdominal pain and fever. The epidemiological data suggest that in Europe, as well as in North America, bacteria of the genus Campylobacter, especially C. jejuni and C. coli, are the most commonly isolated pathogens in infections of the gastrointestinal tract in humans. Epidemiological data indicate that these organisms are a much more common cause of acute diarrhea, mostly in young children, than Salmonella and Yersinia. The lack of specific symptoms makes the diagnosis of campylobacteriosis necessary to carry out specialized microbiological diagnostics. Because so far these studies are performed in our country only in a few laboratories, the overwhelming number of cases of campylobacteriosis are not recorded in Polish epidemiological statistics. The purpose of this paper is to discuss issues related to the microbiological diagnosis of infections caused by C. jejuni and C. coli. It also describes the basic epidemiological and clinical data, as well as current treatment of campylobacteriosis.

    Gut bacteria are an important component of the microbiota ecosystem in the human gut, which is colonized by 1014 microbes, ten times more than the human cells. Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function. However, they can also be potentially harmful due to the change of their composition when the gut ecosystem undergoes abnormal changes in the light of the use of antibiotics, illness, stress, aging, bad dietary habits, and lifestyle. Dysbiosis of the gut bacteria communities can cause many chronic diseases, such as inflammatory bowel disease, obesity, cancer, and autism. This review summarizes and discusses the roles and potential mechanisms of gut bacteria in human health and diseases. PMID:25849657

    Nowadays, viruses of foodborne origin such as norovirus and hepatitis A are considered major causes of foodborne gastrointestinal illness with widespread distribution worldwide. A number of foodborne outbreaks associated with food products of animal and non-animal origins, which often involve multiple cases of variety of food streams, have been reported. Although several viruses, including rotavirus, adenovirus, astrovirus, parvovirus, and other enteroviruses, significantly contribute to incidence of gastrointestinal diseases, systematic information on the role of food in transmitting such viruses is limited. Most of the outbreak cases caused by infected food handlers were the source of 53% of total outbreaks. Therefore, prevention and hygiene measures to reduce the frequency of foodborne virus outbreaks should focus on food workers and production site of food products. Pivotal strategies, such as proper investigation, surveillance, and reports on foodborne viral illnesses, are needed in order to develop more accurate measures to detect the presence and pathogenesis of viral infection with detailed descriptions. Moreover, molecular epidemiology and surveillance of food samples may help analysis of public health hazards associated with exposure to foodborne viruses. In this present review, we discuss different aspects of foodborne viral contamination and its impact on human health. This review also aims to improve understanding of foodborne viral infections as major causes of human illness as well as provide descriptions of their control and prevention strategies and rapid detection by advanced molecular techniques. Further, a brief description of methods available for the detection of viruses in food and related matrices is provided.

    Sports injury and illness surveillance is the first step in injury and illness prevention, and is important for the protection of both athlete health and performance in major competitions. To identify the prevalence, severity nature and causes of athlete injuries and illnesses in the Great Britain Olympic Team (TeamGB) during the Sochi 2014 Winter Olympic Games. The observational prospective cohort study followed the Great Britain Injury/Illness Performance Project surveillance methodology and obtained information on injuries and illnesses that occurred during the Games between 30 January and 23 February 2014 in TeamGB athletes (n=56). Among the 56 TeamGB athletes, there were 27 injuries and 11 illnesses during the Olympic Games period. This equated to 39% sustaining at least one injury and 18% at least one illness, with an incidence of 48.2 injuries and 19.6 illnesses per 100 athletes, respectively. Of all injuries and illnesses, 9% and 7%, respectively, resulted in time loss. The risk of sustaining an injury was highest for freestyle skiing, skeleton and snowboarding; and lowest for curling, biathlon and Alpine skiing (with no reported injuries); with the lower limb being the most commonly injured location. Respiratory system illnesses were most frequently reported overall, and older female athletes were the ones most affected by illness. The risk of injury was double the risk of illness for TeamGB athletes. Overall, the rate of time-loss issues was low. Methodological considerations are important when interpreting data, and prevention strategies should focus on those issues causing the greatest risk, in terms of prevalence and severity, to athlete health and performance.

  4. Correlation of mental illness and HIV/AIDS infection

    2016-01-01

    Full Text Available HIV/AIDS is among the leading causes of morbidity and mortality in world. There are more than 35 million people living with HIV/AIDS in the world. Although the annual incidence of HIV infection is decreasing globally, HIV prevalence is rising due to development of more effective treatment and higher survival. Iran suffers from concentrated HIV epidemics among injecting and non-injecting drug users. There are more than 27 thousand registered cases of HIV infection and it is estimated that there are above seventy eight thousand cases in the country. Regarding the burden of disease, it is projected that HIV/AIDS will have the highest growth during the next 10 years. The outcome of this epidemics will be determined by human behavior. HIV, psychiatric disorders and substance use disorders are closely correlated and are accompanied by similar risk factors. They also share common consequences such as stigma and discrimination. Correlation of psychiatric disorders, as one of the most influential determinants of our behavior, and HIV/AIDS infection is reviewed in this narrative article. Psychiatric disorders are associated with greater risk of HIV acquisition. Substance use disorders, both injecting and non-injecting, as well as severe mental illnesses put the individual at higher risk of acquiring HIV infection. Impaired judgment, diminished inhibition and control over behaviors, lack of insight and poor self-care have been proposed as the underlying mechanisms. On the other hand, HIV infection may put the individual at greater risk of developing a mental illness. Coping with a chronic and life-threatening illness, fear of stigma and discrimination, CNS invasion of the virus as well as the adverse neuropsychiatric side effects of anti-retroviral medications may all contribute to establishment of a psychiatric disorder. Although there exists a bi-directional correlation between mental health problems and HIV/AIDS infection, this reciprocity goes beyond

  5. Challenges of connectedness in personal recovery for rural mothers with mental illness.

    2018-04-01

    Social connection is a fundamental human need, but challenging for individuals with characteristics that are socially stigmatized. Parenting with mental illness presents obstacles, as well as opportunities, for connection. In the present study, we examined connectedness within a personal recovery paradigm for rural mothers with a mental illness. In-depth interviews with 17 mothers with a mental illness, utilizing constructivist grounded theory, resulted in six categories of meaning, including 'yearning for connection', 'connecting intensely', 'encountering rejection and exclusion', 'choosing isolation', 'being known', and 'finding peers/helping others'. Women expressed a strong desire for connection, but for many, prior experiences of trauma and rejection created barriers to the development of trust, preventing some women from seeking opportunities for connection. Connectedness to self and significant others, and a broader life meaning and purpose can support and expedite personal recovery from mental illness for rural women. However the factors that contribute to the mental illness might also inhibit the development of trust needed to attain social connection. Increasing connectedness in mothers with mental illness is a complex endeavour requiring concerted focus as distinct from other service-delivery goals. The perinatal period could be a key time for intervention. © 2017 Australian College of Mental Health Nurses Inc.

    The major cause of eosinophilic meningitis in Taiwan is Angiostrongylus cantonensis. Humans are infected by ingesting terrestrial and freshwater snails and slugs. In 1998 and 1999, two outbreaks of eosinophilic meningitis caused by A. cantonensis infection were reported among 17 adult male immigrant Thai laborers who had eaten raw golden apple snails (Pomacea canaliculata). Another outbreak associated with consuming a health drink consisting of raw vegetable juice was reported in 2001. These adult cases differed from reports in the 1970s and 1980s, in which most of the cases were in children. With improvements in public health and education of foreign laborers, there have since been only sporadic cases in Taiwan. Review of clinical research indicates inconsistent association of Magnetic Resonance Imaging (MRI) results with clinical features of eosinophilic meningitis. MRI features were nonspecific but there was an association between the presence of high brain MRI signal intensities and severity of peripheral and cerebrospinal fluid (CSF) eosinophilia. Inflammatory markers have been identified in the CSF of patients with eosinophilic meningitis caused by A. cantonensis infection, and vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), and the matrix metalloproteinase system may be associated with blood-brain barrier disruption. Eosinophilic meningitis caused by A. cantonensis infection is not a reportable disease in Taiwan. It is important that a public advisory and education program be developed to reduce future accidental infection.

    2016-10-01

    Consumer responses to food product recalls have been documented, but there is little information on how consumers respond to illnesses or outbreaks associated with food service facilities. This study uses an on-line survey of 885 adults conducted in 2012 to determine how respondents changed their dining behavior following personal experiences with and secondhand reports of gastrointestinal illness believed to be associated with food service facilities. In response to personally experiencing gastrointestinal illness that they attributed to a food service facility, 90% of survey participants reported that they avoided the implicated facility for a time following the incident; almost one-half decided to never return to the facility they believed had made them ill. In response to a secondhand report of gastrointestinal illness, 86% of respondents reported they would avoid the implicated facility for a time, and 22% said they would never return to the facility. After both personal experiences of illness and secondhand reports of illness, consumer responses were significantly more severe toward the implicated facility than toward all other food service facilities. Frequent diners avoided facilities for shorter periods of time and were less likely to never go back to a facility than were infrequent diners. The survey results indicate that 24 to 97 fewer meals were purchased per respondent, or a 11 to 20% reduction in meals purchased outside the home, in the year following respondents' illness. Future estimates of the economic burden of foodborne illnesses, including those caused by noroviruses, should consider the impacts on the food service industry attributable to changes in consumer behavior, in addition to health care costs and loss of productivity.

    The human parechovirus (HPeV), mainly genotype 3, may cause severe illness in young infants and neonates, including sepsis-like illness and central nervous system (CNS) infection. We lack data concerning the impact and symptoms of HPeV infection in infants in Austria. The aim of the study is to evaluate the spectrum of symptoms and findings in infants with the parechovirus in Vienna and its environs. Patients younger than 3 months of age, with clinically suspected sepsis-like illness or CNS infection and a positive polymerase chain reaction (PCR) for HPeV, were included in the study. Medical records were analyzed retrospectively. Twenty patients were included in the study from 2009 to 2013. The most frequent manifestations were fever and neurological symptoms (89 and 80 %, respectively). Fifty percent of the infants had white blood cell counts out of range. The most notable aspect was cerebral hemorrhage in three neonates, which has not been reported earlier in association with HPeV infection. In Austria, HPeV is a relevant pathogen in sepsis-like disease in infants. The clinical presentation is similar to that described in other studies; cerebral hemorrhage is a new aspect. • Parechovirus infection can cause severe illness in infants. • Symptoms have been described to involve all organs; sepsis-like signs, fever, and irritability are most frequent. • Also in Austria, HPeV plays an important role in severe illnesses in infants. • Severe intracranial hemorrhage is described as a new finding.

  10. Geneticization of deviant behavior and consequences for stigma: the case of mental illness.

    Science.gov (United States)

    Phelan, Jo C

    2005-12-01

    One likely consequence of the genetics revolution is an increased tendency to understand human behavior in genetic terms. How might this "geneticization" affect stigma? Attribution theory predicts a reduction in stigma via reduced blame, anger, and punishment and increased sympathy and help. According to "genetic essentialist" thinking, genes are the basis of human identity and strongly deterministic of behavior. If such ideas are commonly accepted, geneticization should exacerbate stigma by increasing perceptions of differentness, persistence, seriousness, and transmissibility, which in turn should increase social distance and reproductive restrictiveness. I test these predictions using the case of mental illness and a vignette experiment embedded in a nationally representative survey. There was little support for attribution theory predictions. Consistent with genetic essentialism, genetic attributions increased the perceived seriousness and persistence of the mental illness and the belief that siblings and children would develop the same problem. Genetic attribution did not affect reproductive restrictiveness or social distance from the ill person but did increase social distance from the person's sibling, particularly regarding intimate forms of contact involving dating, marriage, and having children.

  11. Oxygen in the critically ill: friend or foe?

    2018-04-01

    To examine the potential harmful effects of hyperoxia and summarize the results of most recent clinical studies evaluating oxygen therapy in critically ill patients. Excessive oxygen supplementation may have detrimental pulmonary and systemic effects because of enhanced oxidative stress and inflammation. Hyperoxia-induced lung injury includes altered surfactant protein composition, reduced mucociliary clearance and histological damage, resulting in atelectasis, reduced lung compliance and increased risk of infections. Hyperoxemia causes vasoconstriction, reduction in coronary blood flow and cardiac output and may alter microvascular perfusion. Observational studies showed a close relationship between hyperoxemia and increased mortality in several subsets of critically ill patients. In absence of hypoxemia, the routine use of oxygen therapy in patients with myocardial infarction, stroke, traumatic brain injury, cardiac arrest and sepsis, showed no benefit but rather it seems to be harmful. In patients admitted to intensive care unit, a conservative oxygen therapy aimed to maintain arterial oxygenation within physiological range has been proved to be well tolerated and may improve outcome. Liberal O2 use and unnecessary hyperoxia may be detrimental in critically ill patients. The current evidence supports the use of a conservative strategy in O2 therapy to avoid patient exposure to unnecessary hyperoxemia.

    2017-03-01

    Full Text Available Introduction: Community-acquired pneumonia (CAP is associated with high morbidity and mortality rates. Despite methicillin-resistant Staphylococcus aureus (MRSA having often been associated with nosocomial pneumonia, the condition of some MRSA CAP patients is severe enough to warrant their being admitted to ICU. Objective: The purpose of this study is to conduct a systematic review of the literature on antibiotic treatment of MRSA CAP in critically-ill patients. Material and methods: An online search was conducted for locating articles on MRSA CAP in critically ill patients. Relevant publications were identified in PUBMED, the BestPractice database, UpToDate database and the Cochrane Library for articles published in English within the December 2001 - April 2016 time frame. Results: A total of 70 articles were found to have been published, 13 (18.8% having been included and 57 (81.4% excluded. Cohort studies were predominant, having totaled 16 in number (20.7% as compared to one sole cross-sectional study (3.5%. Conclusions: The experience in the treatment of MRSA CAP in patients requiring admission to ICU is quite limited. Vancomycin or linezolid seem to be the treatments of choice for MRSA CAP, although there not be any specific recommendation in this regard. It may be useful to use alternative routes, such as administration via aerosolized antibiotics, continuous infusion or in association with other antibiotics.

    Silvio A. Ñamendys-Silva

    2011-01-01

    Full Text Available Influenza B virus infections are less common than infections caused by influenza A virus in critically ill patients, but similar mortality rates have been observed for both influenza types. Pneumonia caused by influenza B virus is uncommon and has been reported in pediatric patients and previously healthy adults. Critically ill patients with pneumonia caused by influenza virus may develop acute respiratory distress syndrome. We describe the clinical course of a critically ill patient with diffuse large B-cell lymphoma nongerminal center B-cell phenotype who developed acute respiratory distress syndrome caused by influenza B virus infection. This paper emphasizes the need to suspect influenza B virus infection in critically ill immunocompromised patients with progressive deterioration of cardiopulmonary function despite treatment with antibiotics. Early initiation of neuraminidase inhibitor and the implementation of guidelines for management of severe sepsis and septic shock should be considered.

    1996-01-01

    The purpose of this study was to explore the illness practices of Yemeni-Arab Americans and to generate illness themes based on informant reports. A convenient sample of 30 Yemeni-Arab American women was selected from Dearborn, Michigan. A content analysis of interview data was the basis for data analysis. The Arabic language was used in all the interviews due to enability of the informants to speak English. Thirty-three illness practices were identified by the study informants. Analysis of interview data indicated that informants relied heavily on religious explanations of illness practices. Several cultural themes were deduced from collected data. Among these were belief in an omnipotent deity who is the cause of all that is, confidence in the rational mind of man and empirical knowledge, susceptibility to disease based on gender, reliance and trust in health care providers and desirability of adapting to change.

    Environmental illness, a hypothesized disease caused by exposure to substances such as combustion products, pesticides, food additives, and Candida albicans, is discussed. The case of a patient with environmental illness and systemic candidiasis for six weeks with ketoconazole, liver enzyme concentrations increased. One month after discontinuation of ketoconazole, the liver enzyme concentrations decreased; however, over the next five months, liver enzymes and bilirubin increased. The patient developed encephalopathy and eventually was transferred to a medical center for possible liver transplant. A review of the literature pertaining to ketoconazole hepatotoxicity is also presented.16 references.

    2016-01-01

    Vector-borne diseases constitute a diversified group of illnesses, which are caused by a multitude of pathogens transmitted by arthropod vectors, such as mosquitoes, fleas, ticks, and sand flies. Proper management of these diseases is important from both human and veterinary medicine standpoints, given that many of these pathogens are transmissible to humans and dogs, which often live in close contact. In this review, we summarize the most important vector-borne diseases of dogs and humans and the best practices for their prevention. The control of these diseases would ultimately improve animal and human health and wellbeing, particularly in developing countries in the tropics, where the risk of these diseases is high and access to health care is poor.

    With the modernization of Chinese society and increased general levels of education, the stigmatization of mental illness may have declined, especially among advanced students. However, misunderstandings about mental illness may remain and adversely affect service delivery to this population. Educational initiatives in psychiatry may support a more accepting and scientific understanding of these illnesses among college students. Attitudes towards mental illness were compared between 161 medical students who received a basic 48-hour introductory course in psychiatry and 170 college students who had not received such a course using a 43-item questionnaire. Previous factor analysis had shown this questionnaire to address four factors: 1. Personal willingness to socialize with people with mental illness; 2. Support for normalizing relationships and activities of people with mental illness; 3. Rejecting supernatural explanations of mental illness; and 4. Agreeing with a biopsychosocial view of the etiology of mental illness. Analysis of Co-Variance was used to compare the groups on these factors with adjustment for significant differences in age and years of education. The two groups of students scored similarly on the socializing factor (P = 0.252), the rejection of supernatural causes factor (P = 0.248) and the normalizing factor (P = 0.362), but students who had the didactic psychiatry course scored more positively on the biopsychosocial factor (percent difference = 15.06%, P = 0.001). A single formal psychiatry course may improve understanding of the biopsychosocial causes of mental illness but did not affect other attitudinal domains among Chinese college students.

    Apart from influencing the quality of life, occupational injuries and illnesses can pose a large economic burden to a society. There are many studies that estimate the costs of occupational injuries and illnesses in highly developed economies, but the evidence for other countries is scarce. This study aimed to estimate the financial costs of occupational injuries and illnesses to Croatian government and employers in 2015. Workers were excluded due to the lack of data. Costs were estimated by analysing available data sources on occupational health and safety. Financial costs were grouped in several categories: medical costs, productivity losses, disability pensions, compensation for physical impairment, administrative costs, and legal costs. Unlike in other studies, the costs of compliance with occupational safety and health regulations were also investigated. In 2015, financial costs to employers were twice higher than costs to the government (HRK 604.6 m vs HRK 297 m). Employers additionally covered around HRK 300 m of compliance costs. Taking into account that financial costs of occupational injuries and illnesses are significant, even without including the costs to workers, policy makers should put additional efforts into their prevention. A prerequisite is transparency in Croatian Health Insurance Fund's expenditures, as well as more detailed data on lost days from work by industries, causes of injury etc. Organisations in charge of occupational health and safety and policy makers should observe relevant statistics in monetary terms too.

    Full Text Available This study aims to identify and analyze the social representations of body for men after the illness from prostate cancer. Narrative interviews were conducted with 08 men with ages ranging from 50 and 70 years, diagnosed with this disease and who had undergone oncological treatment, for at least one year. The interviews were recorded, transcribed and analyzed using the Interpretative Phenomenological Approach. The results show that before the illness, the participants represented their bodies as strong, resistant and healthy taking in the hegemonic masculinity model an important anchorage point for these representations. The absence of symptoms that cause bodily discomforts contributed to the feeling of healthy body. The search for health services only occurred after the manifestation of the first symptoms and its exacerbations, which limited their daily actions and change their daily lives. Participants mentioned the illness by prostate cancer and oncological treatment proposals, in particular the prostatectomy, as a remarkable experience that producer of great physical and psychological discomfort. After the illness, the men began to represent their bodies as fragile, sick and weak. Those interviewed point to the impact of body changes, especially those related to sexual and urological dysfunctions in ways of thinking, feeling and acting in relation to his masculinity. Accordingly, the limitations imposed by illness and oncological treatments are opposed to the hegemonic masculinity model, favoring the feeling of being less a man than before the illness.

    2014-04-01

    This is a review of bibliographic aspects associated to the knowledge about human bartonelosis before and after the death of Daniel Alcides Carrion. Emphasis is placed on stimulus in the development of medical research in Peru by the self-inoculation and subsequent death of Carrion especially in relation to human bartonellosis, conducted by Peruvian researchers and others around the world. The review includes the basic area of knowledge about the bacteria that causes the illness, the host response to infection as well as the biphasic behavior of the disease. The revised bibliography includes contributions to the knowledge of the disease in the last 100 years, now known with the eponym "Carrion's disease".

    BACKGROUND Both genetic variation at the 17q21 locus and virus-induced respiratory wheezing illnesses are associated with the development of asthma. Our aim was to determine the effects of these two factors on the risk of asthma in the Childhood Origins of Asthma (COAST) and the Copenhagen Prospective Study on Asthma in Childhood (COPSAC) birth cohorts. METHODS We tested genotypes at the 17q21 locus for associations with asthma and with human rhinovirus (HRV) and respiratory syncytial virus (RSV) wheezing illnesses and tested for interactions between 17q21 genotypes and HRV and RSV wheezing illnesses with respect to the risk of asthma. Finally, we examined genotype-specific expression of 17q21 genes in unstimulated and HRV-stimulated peripheral-blood mononuclear cells (PBMCs). RESULTS The 17q21 variants were associated with HRV wheezing illnesses in early life, but not with RSV wheezing illnesses. The associations of 17q21 variants with asthma were restricted to children who had had HRV wheezing illnesses, resulting in a significant interaction effect with respect to the risk of asthma. Moreover, the expression levels of ORMDL3 and of GSDMB were significantly increased in HRV-stimulated PBMCs, as compared with unstimulated PBMCs. The expression of these genes was associated with 17q21 variants in both conditions, although the increase with exposure to HRV was not genotype-specific. CONCLUSIONS Variants at the 17q21 locus were associated with asthma in children who had had HRV wheezing illnesses and with expression of two genes at this locus. The expression levels of both genes increased in response to HRV stimulation, although the relative increase was not associated with the 17q21 genotypes.

    Deaths and certain illnesses onboard ships arriving at US ports are required to be reported to the US Centers for Disease Control and Prevention (CDC), and notifications of certain illnesses are requested. We performed a descriptive analysis of required maritime illness and death reports of presumptive diagnoses and requested notifications to CDC's Division of Global Migration and Quarantine, which manages CDC's Quarantine Stations, from January 2010 to December 2014. CDC Quarantine Stations received 2891 individual maritime case reports: 76.8% (2221/2891) illness reports, and 23.2% (670/2891) death reports. The most frequent individual illness reported was varicella (35.9%, 797/2221) and the most frequently reported causes of death were cardiovascular- or pulmonary-related conditions (79.6%, 533/670). There were 7695 cases of influenza-like illness received within aggregate notifications. CDC coordinated 63 contact investigations with partners to identify 972 contacts; 88.0% (855/972) were notified. There was documentation of 6.5% (19/293) receiving post-exposure prophylaxis. Three pertussis contacts were identified as secondary cases; and one tuberculosis contact was diagnosed with active tuberculosis. These data provide a picture of US maritime illness and death reporting and response. Varicella reports are the most frequent individual disease reports received. Contact investigations identified few cases of disease transmission. Copyright © 2017. Published by Elsevier Ltd.

    SUMMARY Introduction: Although, that the general well-being is extensively studied in wide range of contexts, still little place is devoting to relationship between acceptance of illness (AIS and quality of life (QoL, especially among cardiac patients. Aim: The aim of this study was to: (1 determine an association between these two variables; (2 examine relationship between selected variables (age, sex, education level, NYHA class, time since CVDs diagnosis, cardiosurgery intervention and presence of comorbid diseases and quality of life. Material and methods: The study included 172 patients with diagnose cardiac disease. All participants were examined used standardized questionnaires: Short Form of health survey (SF-36 questionnaire and Acceptance of Illness Scale (AIS. Results: The patients presented moderate level of illness acceptance and quality of life level. Over than half of participants did not accept their illness. Significant, positive relatioship between AIS and QoL were noted. NYHA class, number of cardiac hospitalization and time since cardiovascular disease diagnosis was negatively correlated with QoL. Conclusions: Findings presented in this study demonstrated, that AIS is strongly related with QoL.    Key words: illness acceptance, quality of life, AIS, QoL, cardiac diseases.

  11. as a cause of acute-onset febrile illness in cats

    Edward B Breitschwerdt

    2015-08-01

    Full Text Available Case series summary At different time points spanning 6 months, three adopted feral flea-infested cats, residing in the household of a veterinary technician, became acutely anorexic, lethargic and febrile. Enrichment blood culture/PCR using Bartonella alpha Proteobacteria growth medium (BAPGM confirmed initial infection with the same Bartonella henselae genotype in all three cases. With the exception of anemia and neutropenia, complete blood counts, serum biochemical profiles and urinalysis results were within reference intervals. Also, tests for feline leukemia virus, feline immunodeficiency virus, Toxoplasma gondii and feline coronavirus antibodies were negative. Serial daily temperature monitoring in one case confirmed a cyclic, relapsing febrile temperature pattern during 1 month, with resolution during and after treatment with azithromycin. Bartonella henselae Western immunoblot (WB results did not consistently correlate with BAPGM enrichment blood culture/PCR results or B henselae indirect fluorescent antibody (IFA titers, and WB titration results were not informative for establishing antibiotic treatment failure. During the respective follow-up periods, no illnesses or additional febrile episodes were reported, despite repeat documentation of B henselae bacteremia in two cats available for follow-up (one with the same genotype and the other with a different B henselae genotype; one cat was, unfortunately, killed by dogs before follow-up testing. Relevance and novel information We conclude that microbiological diagnosis and treatment of B henselae infection in cats can be challenging, that antibody titration results and resolution of clinical abnormalities may not correlate with a therapeutic cure, and that fever and potentially neutropenia should be differential diagnostic considerations for young cats with suspected bartonellosis.

    Acyclovir is known for its antiviral activity against some pathogenic viruses such as the Epstein-Barr virus (EBV) that causes infectious mononucleosis (IM) and IM-like illness. Therefore, we empirically administered acyclovir to patients with suspected EBV-IM and IM like-illness, upon their admission to our hospital. We admitted 25 patients, who were hospitalized for fever and lymphadenopathy, to the Tohoku University Hospital Infectious Disease Ward. As part of treatment, 8 of these patients were given acyclovir (750 mg/day) with their consent and were assigned to the acyclovir group; the remaining 17 patients were assigned to the control group. The mean age of acyclovir patients (all men) was 42±5.2 years, and that of control patients (13 men and 4 women) was 31±3.0 years. The cause of illness was confirmed as EBV-IM in 6 patients (1, acyclovir; 5, control), and remained unknown for the other 19 IM-like illness patients (7, acyclovir; 12, control). A shorter duration of hospitalization and fever was observed in the acyclovir compared to that in the control patients (hospitalization duration: 16±3.7 vs. 27±7.7 days, P=0.36; fever duration: 4.5±1.8 vs. 18±6.5 days, P=0.04). Additionally, serum amyloid A (SAA) levels were lower in acyclovir than that in control patients (98±37 vs. 505±204 µg/mL, P=0.02). Therefore, we propose that acyclovir is a potential therapeutic agent for both EBV-IM and IM like-illnesses. Future studies should further examine its mechanism of action.

  13. "Satan has afflicted me!" Jinn-possession and mental illness in the Qur'an.

    Islam, F; Campbell, R A

    2014-02-01

    Mental health stigma in Muslim communities may be partly due to a commonly held belief among some Muslims about the supernatural causes of mental illness (i.e. jinn-possession brought on by one's sinful life). A thematic analysis was carried out on four English translations and the Arabic text of the Qur'an to explore whether the connection between jinn-possession and insanity exists within the Muslim holy book. No connection between spirit-possession and madness or mental illness was found. Pagans taunted and labelled people as jinn-possessed only to ostracize and scapegoat. Linking the labelling of people as jinn-possession to a pagan practice may be used to educate Muslims, so they can reassess their community's stigma towards the mentally ill.

  14. Target-specific stigma change: a strategy for impacting mental illness stigma.

    2004-01-01

    In the past decade, mental health advocates and researchers have sought to better understand stigma so that the harm it causes can be erased. In this paper, we propose a target-specific stigma change model to organize the diversity of information into a cogent framework. "Target" here has a double meaning: the power groups that have some authority over the life goals of people with mental illness and specific discriminatory behaviors which power groups might produce that interfere with these goals. Key power groups in the model include landlords, employers, health care providers, criminal justice professionals, policy makers, and the media. Examples are provided of stigmatizing attitudes that influence the discriminatory behavior and social context in which the power group interacts with people with mental illness. Stigma change is most effective when it includes all the components that describe how a specific power group impacts people with mental illness.

    This study intends to contribute to a research tradition that asks how causal attributions of illnesses affect coping behavior. Causal attributions are understood as the most important element of illness representations and coping as a means to preserve quality of life. The issue is applied to a condition so far often neglected in research on illness representations-back pain-and a third concept is added to the picture: culture. The aim of this study is (a) to explore the causal factors to which persons with back pain attribute the further course of their illness, (b) to find out whether the attributed causes are predictors of coping maxims, and (c) to find out whether cultural factors affect attributions and coping and moderate the relationship between the two. A total of 1259 gainfully employed or self-employed persons with recent episodes of back pain were recruited in the three language regions of Switzerland. They were asked to complete a structured online interview, measuring among many other variables attributed causes, coping maxims, and affiliation to one of the Swiss micro-cultures (German-, French- or Italian-speaking). Attributed causes of the illness that can be influenced by a patient go along with more active coping styles. Cultural affiliation impacts on coping maxims independently, but culture moderates the relationship of attributed causes and coping maxims only in two of twenty possible cases. The results show that cultural differences can be analytically incorporated in the models of illness representations. Results may help to improve healthcare providers' communication with patients and plan public health campaigns. The approach to micro-cultural differences and the substantive relationships between alterability of causes and activity in coping may help the further development of models of illness representations.

    Our genetic analyses of uncharacterized bunyaviruses isolated in Peru identified a possible reassortant virus containing small and large gene segment sequences closely related to the Caraparu virus and a medium gene segment sequence potentially derived from an unidentified group C orthobunyavirus. Neutralization tests confirmed serologic distinction among the newly identified virus and the prototype and Caraparu strains. This virus, named Itaya, was isolated in 1999 and 2006 from febrile patients in the cities of Iquitos and Yurimaguas in Peru. The geographic distance between the 2 cases suggests that the Itaya virus could be widely distributed throughout the Amazon basin in northeastern Peru. Identification of a new Orthobunyavirus species that causes febrile disease in humans reinforces the need to expand viral disease surveillance in tropical regions of South America. PMID:25898901

    Ciguatera fish poisoning is a potentially life-threatening disease caused by eating coral reef fish contaminated with ciguatoxins and is the most common marine poisoning. However, existing surveillance systems capture few cases. To improve regional ciguatera surveillance in South Florida, this study compared ciguatera illnesses in the Florida Poison Information Center-Miami (FPICM) call database to ciguatera cases in the Florida Department of Health (FDOH) disease surveillance systems. Univariate and multivariate logistic regression were used to identify predictors of when FPICM reported ciguatera illnesses to FDOH and whether FDOH confirmed reported ciguatera cases. FPICM staff preferentially reported ciguatera illnesses that were of shorter duration (adjusted odds ratio [AOR] = 0.84 per additional illness day; 95% confidence interval [CI] 0.74, 0.97); outbreak-associated (AOR = 7.0; 95% CI 2.5, 19.5); and clinically more severe (AOR = 21.6; 95% CI 2.3, 198.5). Among ciguatera illnesses reported to FDOH, outbreak-associated illnesses were more likely than single, sporadic illnesses to become confirmed surveillance cases (crude OR = 11.1; 95% CI 2.0, 62.5). The over-representation of outbreak-associated ciguatera cases underestimates the true contribution of sporadic illnesses to ciguatera disease burden. This bias should be considered when evaluating surveillance systems that include both outbreak-associated and sporadic illness reports.

    Non-disclosure of a cancer diagnosis is a common practice in many Asian cultures where family-based medical decision making is the norm. The present study sought to compare Indian cancer patients who were aware versus unaware of their cancer diagnosis on a range of patient characteristics, levels of psychological distress and illness perceptions. A sample of 329 Indian cancer patients were interviewed about their understanding of their illness (to assess awareness of a cancer diagnosis) and administered the following measures: the modified Rotterdam Symptom Checklist, the Hospital Anxiety and Depression Scale, and the Brief Illness Perceptions Questionnaire. Demographic and medical details were also obtained. Over half of the sample (54.1%) was unaware of their cancer diagnosis. A logistic regression analysis predicting perceived diagnostic disclosure indicated that awareness of a cancer diagnosis was associated with being involved in medical decisions, receiving multiple treatments, longer treatment durations, greater perceived understanding of one's illness (illness coherence) and citing a cause for one's illness. The results highlight the importance of the context in which decisions about the patient's illness are made (e.g. by whom) as well as illness perceptions relating to patients' understanding of their illness.

    Upper respiratory illness (URI) is the most common medical condition affecting elite athletes. The aims of this study were to identify and evaluate the incidence, pathogenic etiology, and symptomatology of acute URI during a 5-month training and competition period. Thirty-two elite and 31 recreationally competitive triathletes and cyclists, and 20 sedentary controls (age range 18.0-34.1 yr) participated in a prospective surveillance study. Nasopharyngeal and throat swabs were collected from subjects presenting with two or more defined upper respiratory symptoms. Swabs were analyzed using microscopy, culture, and PCR testing for typical and atypical respiratory pathogens. The Wisconsin Upper Respiratory Symptom Survey (WURSS-44) was used to assess symptomatology and functional impairment. Thirty-seven URI episodes were reported in 28 subjects. Incidence rate ratios for illness were higher in both the control subjects (1.93, 95% CI: 0.72-5.18) and elite athletes (4.50, 1.91-10.59) than in the recreationally competitive athletes. Infectious agents were identified in only 11 (two control, three recreationally competitive, and six elite) out of 37 illness episodes. Rhinovirus was the most common respiratory pathogen isolated. Symptom and functional impairment severity scores were higher in subjects with an infectious pathogen episode, particularly on illness days 3-4. The results confirm a higher rate of URI among elite athletes than recreationally competitive athletes during this training and competition season. However, because pathogens were isolated in fewer than 30% of URI cases, further study is required to uncover the causes of unidentified but symptomatic URI in athletes. Despite the common perception that all URI are infections, physicians should consider both infectious and noninfectious causes when athletes present with symptoms.

  2. Irradiation's promise: fewer foodborne illnesses?

    1986-01-01

    Food irradiation offers a variety of potential benefits to the food supply. It can delay ripening and sprouting of fruits and vegetables, and substitute for chemical fumigants to kill insects. However, one of the most important benefits of food irradiation is its potential use for destroying microbial pathogens that enter the food supply, including the two most common disease causing bacteria: salmonella and campylobacter. Animal products are one of the primary carriers of pathogens. Food borne illnesses are on the rise, and irradiation of red meats and poultry could significantly reduce their occurrence. Food irradiation should be examined more closely to determine its possible benefits in curtailing microbial diseases

    Although carers' reactions to schizophrenic illness in a close family member may have important implications for the patient and for themselves, little is known of factors that influence the way carers respond. In the area of physical health problems, people's models of their illness or illness representations have been found to be related to the ways they react and cope with their illness. This study examines the use of a modified form of the Illness Perception Questionnaire (IPQ) to investigate illness models in a sample of carers of schizophrenia patients. Forty-seven carers participated. The psychometric properties of the modified IPQ were examined, and a number of carer and patient outcomes were investigated in relation to carer scores on the illness identity, consequences, control-cure and timeline subscales of the modified IPQ. These outcomes included measures of carer distress and burden, expressed emotion dimensions, and patient functioning. The modified IPQ was found to be a reliable measure of carers' perceptions of schizophrenia. Carer functioning, the patient-carer relationship and patient illness characteristics were associated with different dimensions of illness perceptions. The findings support the proposal that carer cognitive representations of the illness may have important implications for both carer and patient outcomes in schizophrenia.

    This article explores how people in the Andes incorporate beliefs from both biomedical and ethnomedical systems in treating folk illnesses that often involve spiritual beings. The article focuses on the kharisiri-one who is believed to steal fat and blood from unsuspecting humans to make exchanges with the devil. The kharisiri in turn is rewarded with good fortune. Victims of kharisiris, however, fall ill and may die if untreated. Historically, kharisiri victims relied on ethnomedicine for treatment, but it appears biomedical pills are now perceived by some as an effective treatment. By drawing on participants' attitudes towards biomedicine, and how people in the Andes conceptualize health, this article theorizes as to why biomedical pills are sought to treat kharisiri attacks but not for other folk illnesses. Fieldwork was conducted in Arequipa and Yunguyo among market vendors, who make up a significant portion of Peru's working population. This type of work increases the risk of different illnesses due to work conditions like exposure to extreme temperatures, long-distance travel, and social dynamics. Biomedical and ethnomedical products are often sold in and around marketplaces, making vendors a compelling group for exploring issues relating to treatment systems. Qualitative data was collected in 2011 with a follow-up visit in 2013. Participant observation, informal conversations, and unstructured interviews with 29 participants informed the study. Participants unanimously reported that biomedical pills are not capable of treating folk illnesses such as susto and mal de ojo. Several participants reported that pharmaceutical pills can cure kharisiri victims. In comparison to other folk illnesses that involve spiritual beings, those who fall ill from a kharisiri attack lose physical elements (fat and blood) rather than their soul (ánimo) or becoming ill due to a misbalance in reciprocal relations-either with humans or non-human beings such as Pachamama.

    Adults with mental illness may experience a higher incidence of dysphagia and choking due to factors such as medication side effects and behavioural abnormalities. The aim of this study was to determine the frequency of dysphagia and the most effective interventions for this population. Studies published up to August 2010 were sought via a comprehensive electronic database search (CINAHL, PsycINFO, MEDLINE, PubMed, Cochrane, and Embase). Studies reporting dysphagia frequency or dysphagia intervention outcomes in adults with mental illness were included. Two reviewers independently assessed study eligibility and quality, and the results were synthesised descriptively. Ten studies were identified, each describing dysphagia frequency or death due to choking asphyxiation. No studies evaluating intervention effectiveness were identified. Study quality was limited by subjective assessment of outcomes. Six studies presented dysphagia frequencies ranging from 9 to 42% in varying subgroups. Four studies presented the frequency of choking asphyxiation death, including a large survey that concluded that adults with organic mental illness were 43 times more likely to die of this cause than the general population. Dysphagia is a common and significant cause of morbidity and mortality in adults with mental illness and our review found that there is a lack of studies evaluating the effectiveness of intervention techniques.

A questionnaire was administered to parents-tutors of children-adolescents with mental disorders, and to healthcare professionals of the Hospital de Niños de la Santísima Trinidad Córdoba (Argentina). Data processing was performed by means of frequency analysis. 68.5% of parents-tutors and 51.8% of healthcare professionals answered that mental illnesses are never considered like any other illness. Diagnose and treatment is perceived as a stigma by 25.9% of healthcare professionals. For 88.1% of parents-tutors and 9.8% of healthcare professionals, children and adolescents with mental illnesses are never dangerous. 77.1% of parents and 18.4% of professionals stated that people are never afraid of children-adolescents with MI. 42.8% of children-adolescents were excluded from school and 28.5% from family activities. mental illness during childhood entails a stigma that compromises development, equal opportunity and human rights.

    To provide a detailed picture of the extent, nature and quality of portrayal of mental health/illness in Australian non-fiction media. Media items were retrieved from Australian newspaper, television and radio sources over a 1-year period, and identifying/descriptive data extracted from all items. Quality ratings were made on a randomly selected 10% of items, using an instrument based on criteria in Achieving the Balance (a resource designed to promote responsible reporting of mental health/illness). Reporting of mental health/illness was common, with 4351 newspaper, 1237 television and 7801 radio items collected during the study period. Media items most frequently focused on policy/program initiatives in mental health (29.0%), or on causes/symptoms/treatment of mental illnesses (23.9%). Stories about mental health issues in the context of crime were relatively uncommon, accounting for only 5.6% of items. Most media items were of good quality on eight of the nine dimensions; the exception was that details of appropriate help services were only included in 6.4% of items. In contrast to previous research, the current study found that media reporting of mental health/illness was extensive, generally of good quality and focused less on themes of crime and violence than may have been expected. This is encouraging, since there is evidence that negative media portrayal of mental health/illness can detrimentally affect community attitudes. However, there are still opportunities for improving media reporting of mental health/illness, which should be taken up in future media strategies.

    Enterovirus (EV) and human parechovirus (HPeV) are major causes of sepsis-like illness in infants under 90 days of age and have been identified as neurotropic. Studies about acute and long-term neurodevelopment in infants with sepsis-like illness without the need for intensive care are few. This study investigates cerebral imaging and neurodevelopmental outcome following EV and HPeV infection in these infants. We studied infants under 90 days of age who were admitted to a medium care unit with proven EV- or HPeV-induced sepsis-like illness. In addition to standard care, we did a cerebral ultrasound and cerebral magnetic resonance imaging (MRI), as well as neurodevelopmental follow-up at 6 weeks and 6 months and Bayley Scale of Infant and Toddler Development 3rd edition (BSID-III) investigation at 1 year of age. Twenty-six infants, 22 with EV and 4 with HPeV, were analysed. No abnormalities were detected at cerebral imaging. At 1 year of age, two infants had a moderate delay on both the motor and cognitive scale, one on the cognitive scale only and three others on the gross motor scale only. Although our study population, especially the number of HPeV positive infants is small, our study shows that these infants do not seem to develop severe neurodevelopmental delay and neurologic sequelae more often than the normal Dutch population. Follow-up to school age allows for more reliable assessments of developmental outcome and is recommended for further studies to better assess outcome. What is known: • Enterovirus and Human Parechovirus infections are a major cause of sepsis-like illness in young infants. • After intensive care treatment for EV or HPeV infection, white matter abnormalities and neurodevelopmental delay have been described. What is new: • In our 'medium care' population, no abnormalities at cerebral imaging after EV- or HPeV-induced sepsis-like illness have been found. • At 1 year of age, infants who had EV- or HPeV-induced sepsis

    2016-04-01

    All elements of the gut - the epithelium, the immune system, and the microbiome - are impacted by critical illness and can, in turn, propagate a pathologic host response leading to multiple organ dysfunction syndrome. Preclinical studies have demonstrated that this can occur by release of toxic gut-derived substances into the mesenteric lymph where they can cause distant damage. Further, intestinal integrity is compromised in critical illness with increases in apoptosis and permeability. There is also increasing recognition that microbes alter their behavior and can become virulent based upon host environmental cues. Gut failure is common in critically ill patients; however, therapeutics targeting the gut have proven to be challenging to implement at the bedside. Numerous strategies to manipulate the microbiome have recently been used with varying success in the ICU. Copyright © 2016 Elsevier Inc. All rights reserved.

    Tactical trainees, like those entering the police force, are required to undergo vigorous training as part of their occupational preparation. This training has the potential to cause injuries. In addition, the physical training, communal living and pressures of tactical training are known to induce immune suppression and have the potential to increase the risk of illness. The aim of this study was to investigate the relationship between leg power, as measured by a vertical jump (VJ), and rates of reported injuries and illnesses during police recruit training. Retrospective data from recruits (n = 1021) undergoing basic police recruit training at an Australian Police Force College was collected. Recruits completed a VJ assessment at the commencement of their second state of training. Formally reported illness and injuries were collected 12 weeks later, following completion of training. Correlations between VJ height and rates of reported illness and injury were low (r = -0.16 and -0.09, respectively) but significant (p Police recruits with lower VJ height are at a significantly greater risk of suffering an injury or illness during police basic recruit training.

    2002-10-01

    Because there are no published reports of depictions of mental illness in print media based on national samples, we set out to prospectively collect and analyse a near complete New Zealand sample of print media. A commercial clipping bureau was contracted to provide cuttings of all items with any mental health or illness aspect over a four week period. These items were analysed for potentially positive and negative depictions and how mental illness was represented within each item. An independent search for additional newspaper items concerning one prominently featured topic indicated that the rate of identification of relevant stories was at least 91%. The collection consisted of six hundred print items which were most commonly news or editorial pieces (n = 562, 93.7%). Negative depictions predominated, with dangerousness to others (n = 368, 61.3%) and criminality (n = 284, 47.3%) being the most common. Positive depictions, including human rights themes, leadership and educational accomplishments occurred in 27% (n = 164) of all items. Generic mental illness terminology without reference to specific diagnostic categories was present in 47% of all items (n = 284). Negative depictions that predominate confirm the stereotypic understanding of mental illness that is stigmatizing. These findings underscore the challenge facing us as mental health professionals attempting to change attitudes towards mental disorders when the stereotypes are so regularly reinforced.

Studies have been undertaken looking into the knowledge, attitudes, and beliefs (KAB about mental illness among residents in Qatar; however, none have looked specifically at students in higher education. The aim of this study was to understand the KAB toward mental illness among students at a Qatari university and determine if there are any differences based on gender, nationality, and college type. Methods: A convenience sample of students from all genders, colleges, and nationalities was approached to participate in a survey that consisted of four sections: demographic, beliefs, attitudes, and help-seeking and treatment preferences associated with mental illness. Chi-square testing was performed to test for differences in the distribution of proportions of our primary outcomes (students’ beliefs, attitudes, and help-seeking and treatment preferences. Results: A total of 282 students completed the survey. The majority of the participating students were females (59.3%, non-Qataris (64.3%, and enrolled in science-based colleges (62.7%. Beliefs reflecting poor mental health literacy, such as “medications to treat mental illness can cause addiction”, “mental illness is not like any other illness”, or that “mental illness is a punishment from God”, were reported by a majority of students (84.4%, 56.7%, and 50.2%, respectively. Stigmatizing attitudes that were endorsed by a majority of students included believing that people with mental illness cannot have regular jobs (60.2%, that people with mental illness are dangerous (65.7%, and that they would not marry

    2018-03-01

    During critical illness, dramatic alterations in neutrophil biology are observed including abnormalities of granulopoeisis and lifespan, cell trafficking and antimicrobial effector functions. As a result, neutrophils transition from powerful antimicrobial protectors into dangerous mediators of tissue injury and organ dysfunction. In this article, the role of neutrophils in the pathogenesis of critical illness (sepsis, trauma, burns and others) will be explored, including pathological changes to neutrophil function during critical illness and the utility of monitoring aspects of the neutrophil phenotype as biomarkers for diagnosis and prognostication. Lastly, we review findings from clinical trials of therapies that target the harmful effects of neutrophils, providing a bench-to-bedside perspective on neutrophils in critical illness.

    2006-01-11

    International genome sequencing projects have produced billions of nucleotides (letters) of DNA sequence data, including the complete genome sequences of 74 organisms. These genome sequences have created many new scientific opportunities, including the ability to identify sequence variations among individuals within a species. These genetic differences, which are known as single nucleotide polymorphisms (SNPs), are particularly important in understanding the genetic basis for disease susceptibility. Since the report of the complete human genome sequence, over two million human SNPs have been identified, including a large-scale comparison of an entire chromosome from twenty individuals. Of the protein coding SNPs (cSNPs), approximately half leads to a single amino acid change in the encoded protein (non-synonymous coding SNPs). Most of these changes are functionally silent, while the remainder negatively impact the protein and sometimes cause human disease. To date, over 550 SNPs have been found to cause single locus (monogenic) diseases and many others have been associated with polygenic diseases. SNPs have been linked to specific human diseases, including late-onset Parkinson disease, autism, rheumatoid arthritis and cancer. The ability to predict accurately the effects of these SNPs on protein function would represent a major advance toward understanding these diseases. To date several attempts have been made toward predicting the effects of such mutations. The most successful of these is a computational approach called ''Sorting Intolerant From Tolerant'' (SIFT). This method uses sequence conservation among many similar proteins to predict which residues in a protein are functionally important. However, this method suffers from several limitations. First, a query sequence must have a sufficient number of relatives to infer sequence conservation. Second, this method does not make use of or provide any information on protein structure, which

    Students often miss school because of gastrointestinal and respiratory illnesses. We assessed the effectiveness of a multifactorial intervention, including alcohol-based hand-sanitizer and surface disinfection, in reducing absenteeism caused by gastrointestinal and respiratory illnesses in elementary school students. We performed a school-based cluster-randomized, controlled trial at a single elementary school. Eligible students in third to fifth grade were enrolled. Intervention classrooms received alcohol-based hand sanitizer to use at school and quaternary ammonium wipes to disinfect classroom surfaces daily for 8 weeks; control classrooms followed usual hand-washing and cleaning practices. Parents completed a preintervention demographic survey. Absences were recorded along with the reason for absence. Swabs of environmental surfaces were evaluated by bacterial culture and polymerase chain reaction for norovirus, respiratory syncytial virus, influenza, and parainfluenza 3. The primary outcomes were rates of absenteeism caused by gastrointestinal or respiratory illness. Days absent were modeled as correlated Poisson variables and compared between groups by using generalized estimating equations. Analyses were adjusted for family size, race, health status, and home sanitizer use. We also compared the presence of viruses and the total bacterial colony counts on several classroom surfaces. A total of 285 students were randomly assigned; baseline demographics were similar in the 2 groups. The adjusted absenteeism rate for gastrointestinal illness was significantly lower in the intervention-group subjects compared with control subjects. The adjusted absenteeism rate for respiratory illness was not significantly different between groups. Norovirus was the only virus detected and was found less frequently on surfaces in intervention classrooms compared with control classrooms (9% vs 29%).

    Military health risk assessors, medical planners, operational planners, and defense system developers require knowledge of human responses to doses of biothreat agents to support force health protection and chemical, biological, radiological, nuclear (CBRN) defense missions. This article reviews extensive data from 118 human volunteers administered aerosols of the bacterial agent Francisella tularensis, strain Schu S4, which causes tularemia. The data set includes incidence of early-phase febrile illness following administration of well-characterized inhaled doses of F. tularensis. Supplemental data on human body temperature profiles over time available from de-identified case reports is also presented. A unified, logically consistent model of early-phase febrile illness is described as a lognormal dose-response function for febrile illness linked with a stochastic time profile of fever. Three parameters are estimated from the human data to describe the time profile: incubation period or onset time for fever; rise time of fever; and near-maximum body temperature. Inhaled dose-dependence and variability are characterized for each of the three parameters. These parameters enable a stochastic model for the response of an exposed population through incorporation of individual-by-individual variability by drawing random samples from the statistical distributions of these three parameters for each individual. This model provides risk assessors and medical decisionmakers reliable representations of the predicted health impacts of early-phase febrile illness for as long as one week after aerosol exposures of human populations to F. tularensis. © 2018 Society for Risk Analysis.

    Full Text Available Health is a fundamental human right. The World Health Organization defines it as a "state of complete physical, psychological and social well - being and not merely the absence of disease or infirmity". The health of individuals, however, is also linked to the environment in which they live and especially to their ability to adapt and integrate into their life context. The relationship with the environment is extremely important because it is that interaction that outlines the concept of normality compared to pathology. Such normality needs to be contextualised by gender, geographical origin and by the individuals’ living conditions: as a matter of fact, what is normal for a young person may differ from what is normal for a senior one. That is to say, the concept of health is indeed relative and it is the result of an interesting evolution of the concept of illness. From the first approaches - dealing with the mere treatment of the symptoms - to the promise of a free-from-pain society, science and economics have played a significant role in redefining the dualism health/ illness. The article reflects on these two concepts, health and illness, in history and nowadays, and discusses the future of the medical science.

    While agreement is growing that mental illness burdens the North American economy, how it impacts productivity--particularly compared to physical illness--is unclear. Hypothesizing that lost work days are only the tip of the iceberg, we also examined the association of mental and chronic physical illness with partial work days and days requiring extra effort to function. Data from 4225 employed individuals, aged 18-54, were analyzed. These were a subset of respondents to the Ontario Health Survey's Mental Health Supplement, a 1990/91 epidemiologic survey of households across Ontario, Canada. Psychiatric disorder was assessed using the University of Michigan' modification of WHO's Composite International Diagnostic Interview (UM-CIDI). Similar to US reports, professional/managerial groups had lower rates of affective and anxiety disorders and fewer disability days compared to the rest of the workforce. However, no single occupational group was consistently at greater risk for either physical or psychiatric problems. Even after accounting for sociodemographic characteristics and work conditions, mental and physical status had clear, but different, impacts on productivity. Physical conditions alone had a fairly constant effect across all types of disability days and were the largest contributor to total work day loss. They also significantly impacted partial and extra effort days but were far less important than conditions involving a mental disorder. Respondents with mental health problems, either alone or in combination with physical illnesses, appeared more likely to go to work but to require greater effort to function. WHO projects that mental illness will become the second most important cause of global disease burden in the next century. Our findings suggest that among working individuals, it affects productivity more subtly than does physical illness. However, with an estimated eight percent of Ontario's workforce experiencing more than two months annually of

    Full Text Available Abstract Background Chronic illness and disability can have damaging, even catastrophic, socioeconomic effects on individuals and their households. We examined the experiences of people affected by chronic heart failure, complicated diabetes and chronic obstructive pulmonary disease to inform patient centred policy development. This paper provides a first level, qualitative understanding of the economic impact of chronic illness. Methods Interviews were conducted with patients aged between 45 and 85 years who had one or more of the index conditions and family carers from the Australian Capital Territory and Western Sydney, Australia (n = 66. Content analysis guided the interpretation of data. Results The affordability of medical treatments and care required to manage illness were identified as the key aspects of economic hardship, which compromised patients' capacity to proactively engage in self-management and risk reduction behaviours. Factors exacerbating hardship included ineligibility for government support, co-morbidity, health service flexibility, and health literacy. Participants who were on multiple medications, from culturally and linguistically diverse or Indigenous backgrounds, and/or not in paid employment, experienced economic hardship more harshly and their management of chronic illness was jeopardised as a consequence. Economic hardship was felt among not only those ineligible for government financial supports but also those receiving subsidies that were insufficient to meet the costs of managing long-term illness over and above necessary daily living expenses. Conclusion This research provides insights into the economic stressors associated with managing chronic illness, demonstrating that economic hardship requires households to make difficult decisions between care and basic living expenses. These decisions may cause less than optimal health outcomes and increased costs to the health system. The findings support the necessity

    Full Text Available By necessity, critically ill patients admitted to intensive care units (ICUs have a high level of dependency, which is linked to a variety of negative feelings, such as powerlessness. However, the term dependency is not well defined in the critically ill patients. The concept of “dependency” in critically ill patients was analyzed using a meta-synthesis approach. An inductive process described by Deborah Finfgeld-Connett was used to analyze the data. Overarching themes emerged that reflected critically ill patients’ experience and meaning of being in dependency were (a antecedents: dependency in critically ill patients was a powerless and vulnerable state, triggered by a life-threatening crisis; (b attributes: the characteristic of losing “self” was featured by dehumanization and disembodiment, which can be alleviated by a “self”-restoring process; and (c outcomes: living with dependency and coping with dependency. The conceptual model explicated here may provide a framework for understanding dependency in critically ill patients.

  12. Light Chain Amyloid Fibrils Cause Metabolic Dysfunction in Human Cardiomyocytes.

    Directory of Open Access Journals (Sweden)

    Helen P McWilliams-Koeppen

    Full Text Available Light chain (AL amyloidosis is the most common form of systemic amyloid disease, and cardiomyopathy is a dire consequence, resulting in an extremely poor prognosis. AL is characterized by the production of monoclonal free light chains that deposit as amyloid fibrils principally in the heart, liver, and kidneys causing organ dysfunction. We have studied the effects of amyloid fibrils, produced from recombinant λ6 light chain variable domains, on metabolic activity of human cardiomyocytes. The data indicate that fibrils at 0.1 μM, but not monomer, significantly decrease the enzymatic activity of cellular NAD(PH-dependent oxidoreductase, without causing significant cell death. The presence of amyloid fibrils did not affect ATP levels; however, oxygen consumption was increased and reactive oxygen species were detected. Confocal fluorescence microscopy showed that fibrils bound to and remained at the cell surface with little fibril internalization. These data indicate that AL amyloid fibrils severely impair cardiomyocyte metabolism in a dose dependent manner. These data suggest that effective therapeutic intervention for these patients should include methods for removing potentially toxic amyloid fibrils.

    During recent years, knowledge gaps on drinking water-related gastrointestinal illness have been identified, especially for non-epidemic cases. Pathogen contamination of drinking water during distribution has been suggested to contribute to these cases, but the risk factors are not yet fully understood. During 2014-2015, we conducted an epidemiological study in five municipalities in Sweden, to assess whether incidents in the drinking water distribution system influence the risk of gastrointestinal illness. Telephone interviews were conducted in the affected areas and in reference areas 7-14 days after a reported incident. Symptoms of gastrointestinal illness occurring during the period were documented for each household member. The results showed a significantly elevated risk of vomiting and acute gastrointestinal illness (AGI) in the affected areas, compared to the reference areas (OR vom.  = 2.0, 95% CI: 1.2-3.3; OR AGI  = 1.9, 95% CI: 1.2-3.0). Certain conditions, or risk factors, during the incidents, such as sewage and drinking water pipelines at the same level in the trench, were associated with an elevated risk of AGI and vomiting. Safety measures taken during repair work, like flushing, were also associated with an elevated risk of AGI and vomiting. These results show that incidents in the drinking water distribution network contribute to endemic gastrointestinal illness, especially AGI and vomiting, and that external pathogen contamination of the drinking water is a likely cause of these cases of gastrointestinal illness. The results also indicate that safety measures used today may not be sufficient for eliminating the risk of gastrointestinal illness. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    To systematically study and document regional variations in descriptions of nervios, we undertook a multisite comparative study of the illness among Puerto Ricans, Mexicans, Mexican Americans, and Guatemalans. We also conducted a parallel study on susto (Weller et al. 2002, Culture, Medicine and Psychiatry 26(4): 449-472), which allows for a systematic comparison of these illnesses across sites. The focus of this paper is inter- and intracultural variations in descriptions in four Latino populations of the causes, symptoms, and treatments of nervios, as well as similarities and differences between nervios and susto in these same communities. We found agreement among all four samples on a core description of nervios, as well as some overlap in aspects of nervios and susto. However, nervios is a much broader illness, related more to continual stresses. In contrast, susto seems to be related to a single stressful event.

  18. Differential relationship of coping styles with well-being and ill-being of professional firemen

    Full Text Available In the present study we were interested in how coping styles relate to different indicators of well- and ill-being. We assumed that coping styles are differently related to well- and ill-being indicators because they are theoretically and empirically independent from each other. To examine this assumption we asked 139 professional firemen to fill in measures of coping styles (COPE, EAS, well-being (PANAS, SWLS and ill-being (IES-R, PANAS. The results confirmed the overall importance of non-constructive coping for illbeing and well-being, whereas constructive coping predicted only positive emotionality. The prototypical masculine working environment characteristic for our sample could be the cause that socially/emotionally oriented coping is the weakest predictor of well-being, although other studies report the adaptive role of conscientious dealing with individual’s own emotions as a coping style. Both well- and ill-being measures should be used to get an insight into a complex area of individual’s adaptation to stress.

  19. The genomic era and serious mental illness: a potential application for psychiatric genetic counseling.

    2007-02-01

    Genetic counseling is an important clinical service that is routinely offered to families affected by genetic disorders or by complex disorders for which genetic testing is available. It is not yet routinely offered to individuals with serious mental illnesses and their families, but recent findings that beliefs about the cause of mental illness can affect an individual's adaptation to the illness suggest that genetic counseling may be a useful intervention for this population. In a genetic counseling session the counselor discusses genetic and environmental contributors to disease pathogenesis; helps individuals explore conceptions, fears, and adaptive strategies; and provides nondirective support for decision making. Expected outcomes may include reductions in fear, stigma, and guilt associated with a psychiatric diagnosis; improvements in adherence to prescribed medications; declines in risk behaviors; and reductions in misconceptions about the illness. The authors endorse a multidisciplinary approach in which a psychiatrist and genetic counselor collaborate to provide comprehensive psychiatric genetic counseling.

    Countries that conduct systematic child death reviews report a high proportion of modifiable characteristics among deaths from external causes, and this study examined the trends in Sweden. We analysed individual-level data on external, ill-defined and unknown causes from the Swedish cause of death register from 2000 to 2014, and mortality rates were estimated for children under the age of one and for those aged 1-14 and 15-17 years. Child deaths from all causes were 7914, and 2006 (25%) were from external, ill-defined and unknown causes: 610 (30%) were infants, 692 (34%) were 1-14 and 704 (35%) were 15-17. The annual average was 134 cases (range 99-156) during the study period. Mortality rates from external, ill-defined and unknown causes in children under 18 fell 19%, from 7.4 to 6.0 per 100 000 population. A sizeable number of infant deaths (8.0%) were registered without a death certificate during the study period, but these counts were lower in children aged 1-14 (1.3%) and 15-17 (0.9%). Childhood deaths showed a sustained decline from 2000 to 2014 in Sweden and a quarter were from external, ill-defined or unknown causes. Systematic, interagency death reviews could yield information that could prevent future deaths. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Full Text Available Background & Objectives: Maintenance is an important tool for the petrochemical industries to prevent of accidents and increase operational and process safety success. The purpose of this study was to identify the possible causes of incidents caused by human error in the petrochemical maintenance activities by using Human Factors Analysis and Classification System (HFACS. Methods: This study is a cross-sectional analysis that was conducted in Zagros Petrochemical Company, Asaluyeh-Iran. A checklist of human error-induced incidents was developed based on four HFACS main levels and nineteen sub-groups. Hierarchical task analysis (HTA technique was used to identify maintenance activities and tasks. The main causes of possible incidents were identified by checklist and recorded. Corrective and preventive actions were defined depending on priority.   Results: The content analysis of worksheets of 444 activities showed 37.6% of the causes at the level of unsafe actions, 27.5% at the level of unsafe supervision, 20.9% at the level of preconditions for unsafe acts and 14% of the causes at the level of organizational effects. The HFACS sub-groups showed errors (24.36% inadequate supervision (14.89% and violations (13.26% with the most frequency. Conclusion: In order to prevent and reduce the occurrence of the identified errors, reducing the rate of the detected errors is crucial. Findings of this study showed that appropriate controlling measures such as periodical training of work procedures and supervision improvement decrease the human error-induced incidents in petrochemical industry maintenance.

    Full Text Available John Wong, Bruce E Magun, Lisa J Wood School of Nursing, MGH Institute of Health Professions, Boston, MA, USA Abstract: Exposure of the lungs to airborne toxicants from different sources in the environment may lead to acute and chronic pulmonary or even systemic inflammation. Cigarette smoke is the leading cause of chronic obstructive pulmonary disease, although wood smoke in urban areas of underdeveloped countries is now recognized as a leading cause of respiratory disease. Mycotoxins from fungal spores pose an occupational risk for respiratory illness and also present a health hazard to those living in damp buildings. Microscopic airborne particulates of asbestos and silica (from building materials and those of heavy metals (from paint are additional sources of indoor air pollution that contributes to respiratory illness and is known to cause respiratory illness in experimental animals. Ricin in aerosolized form is a potential bioweapon that is extremely toxic yet relatively easy to produce. Although the aforementioned agents belong to different classes of toxic chemicals, their pathogenicity is similar. They induce the recruitment and activation of macrophages, activation of mitogen-activated protein kinases, inhibition of protein synthesis, and production of interleukin-1 beta. Targeting either macrophages (using nanoparticles or the production of interleukin-1 beta (using inhibitors against protein kinases, NOD-like receptor protein-3, or P2X7 may potentially be employed to treat these types of lung inflammation without affecting the natural immune response to bacterial infections.

    To obtain rapid and reproducible opinions that address mental illness stigma around the world. Random global Web users were exposed to brief questions, asking whether they interacted daily with someone with mental illness, whether they believed that mental illness was associated with violence, whether it was similar to physical illness, and whether it could be overcome. Over a period of 1.7 years, 596,712 respondents from 229 countries completed the online survey. The response rate was 54.3%. China had the highest proportion of respondents in daily contact with a person with mental illness. In developed countries, 7% to 8% of respondents endorsed the statement that individuals with mental illness were more violent than others, in contrast to 15% or 16% in developing countries. While 45% to 51% of respondents from developed countries believed that mental illness was similar to physical illness, only 7% believed that mental illness could be overcome. To test for reproducibility, 21 repeats of the same questions were asked monthly in India for 21 months. Each time, 10.1 ± 0.11% s.e., of respondents endorsed the statement that persons who suffer from mental illness are more violent than others, indicating strong reproducibility of response. This study shows that surveys of constructs such as stigma towards mental illness can be carried out rapidly and repeatedly across the globe, so that the impact of policy interventions can be readily measured. The method engages English speakers only, mainly young, educated males. Copyright © 2015 Elsevier B.V. All rights reserved.

    This study aimed to record and analyse incidence and characteristics of injuries and illnesses incurred during the Indoor Athletics Championships. During the 2011 European Indoor Athletics Championships in Paris, incidence and characteristics of new injuries and illnesses were recorded prospectively by physicians and physiotherapists from national teams and local organizing committee in 631 registered athletes. Around 70% of athletes were covered by the medical teams (response rate: 84%). Thirty injuries, including eight time-loss injuries, were reported, representing an incidence of 47.5 injuries and 29.4 time-loss injuries per 1000 registered athletes. Injury and time-loss injury risk were highest in heptathlon and hurdles. Three-quarters of injuries affected the lower extremity. Thigh strain was the most common diagnosis (n = 7; 23%). Noncontact trauma (n = 9; 30%) was the predominant cause. A total of 18 illnesses were reported. Incidence of illnesses was 28.5 per 1000 registered athletes, with 17% resulting in time lost from sport. Upper respiratory tract infection was the most common diagnosis (n = 8; 44%) followed by upper respiratory tract allergy (n = 3; 17%) and gastroenteritis (n = 3; 17%). Injury and illness incidence and severity were lower during the 2011 European Indoor Athletics Championships than during outdoor championships, probably due to the shorter duration, the fewer number of events, and shorter sprint distances. © 2012 John Wiley & Sons A/S.

    Culture shapes how individuals perceive and respond to others with mental illness. Prior studies have suggested that Asians and Asian Americans typically endorse greater stigma of mental illness compared to Westerners (White Europeans and Americans). However, whether these differences in stigma arise from cultural variations in automatic affective reactions or deliberative concerns of the appropriateness of one's reactions to mental illness remains unknown. Here we compared implicit and explicit attitudes toward mental illness among Asian and Caucasian Americans. Asian Americans showed stronger negative implicit attitudes toward mental illness relative to Caucasian Americans, suggesting that cultural variation in stigma of mental illness can be observed even when concerns regarding the validity and appropriateness of one's attitudes toward mental illness are minimized. Asian Americans also explicitly endorsed greater desire for social distance from mental illness relative to Caucasian Americans. These findings suggest that cultural variations in mental illness stigma may arise from cultural differences in automatic reactions to mental illness, though cultural variations in deliberative processing may further shape differences in these immediate reactions to mental illness.

    2016-03-01

    In recent years, a growing number of young people who experience illness tend to blog about it. In this paper, we question whether and how illness blogs illustrate the intercommunicative aspect of blogging by bringing forth both the literary concept of the implied reader and the sociological concepts of empowerment and agency in the analysis. We argue that young people blogging about serious illness demonstrate the inherent intercommunicative potential of blogging. We also argue that youth blogging about serious illness may represent a fruitful strategy for ill young people to create meaning, stay front-stage in youth communities and build self-esteem and confidence out of chaos. Furthermore, we argue that these blogs may contribute rather unique experience-based knowledge and reflections about existential issues to other young blog readers, who may otherwise not get access to this aspect of life. Youth blogging about serious illness thereby reflects a patient group so far not very visible and through the genre youth stand out as more competent when it comes to illness and healthcare issues than what is often presumed.

    Individuals with a mental health disorder appear to be at increased risk of medical illness. To examine rates of medical illnesses in patients with bipolar disorder (n = 1720) and to examine the clinical course of the bipolar illness according to lifetime medical illness burden. Participants recruited within the UK were asked about the lifetime occurrence of 20 medical illnesses, interviewed using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and diagnosed according to DSM-IV criteria. We found significantly increased rates of several medical illnesses in our bipolar sample. A high medical illness burden was associated with a history of anxiety disorder, rapid cycling mood episodes, suicide attempts and mood episodes with a typically acute onset. Bipolar disorder is associated with high rates of medical illness. This comorbidity needs to be taken into account by services in order to improve outcomes for patients with bipolar disorder and also in research investigating the aetiology of affective disorder where shared biological pathways may play a role.

    We have presented nationally representative data on the prevalence and correlates of mental illness and mental health service use among African American and Caribbean Black (US-born and foreign-born) fathers in the United States. We have reported national estimates of lifetime and 12-month prevalence rates of mental illness, correlates, and service use among African American (n = 1254) and Caribbean Black (n = 633) fathers using data from the National Survey of American Life, a national household survey of Black Americans. We used bivariate cross-tabulations and Cox proportional hazards regression approaches and adjusted for the National Survey of American Life's complex sample design. The prevalence of mental illness, sociodemographic correlates, and service use among Black fathers varied by ethnicity and nativity. US-born Caribbean Black fathers had alarmingly high rates of most disorders, including depression, anxiety, and substance disorders. Mental health service use was particularly low for African American and foreign-born Caribbean Black fathers. These results demonstrate the need for more research on the causes and consequences of mental illness and the help-seeking behavior of ethnically diverse Black fathers.

    The aim of this study was to investigate traditional and alternative therapy for mental illness in Jamaica: patients' conceptions and practitioners' attitudes. The sample included 60 psychiatric patients selected from Ward 21 at the University of the West Indies, Kingston as well as Princess Margaret outpatient clinic, and 30 Afro-centric psychiatric nurses, psychiatrist and clinical psychologists from Kingston and St. Thomas, Jamaica. Patients were interviewed with the Short Explanatory Model Interview (SEMI) and practitioners completed a self administered questionnaire on attitudes towards traditional and alternative medicine. Results indicate that among psychiatric patients more than a third expressed the belief that the overall cause of their mental illness was as a result of supernatural factors. In general, the majority of patients felt that their perception of their problems did not concur with the western practitioner, which in turn caused distress for these patients. In case for those who also sought traditional medicine, they were more inclined to feel pleased about their interaction and the treatment they received. Results from western trained practitioners found that although they acknowledged that traditional medicine plays a major role in the treatment of mental illness among psychiatric patients the treatment was not advantageous. For the most part when all three traditional approaches were examined alternative medicine seemed more favourable than traditional healing and traditional herbal treatment. There is a need to develop models of collaboration that promote a workable relationship between the two healing systems in treating mental illness.

    To compare bariatric surgery outcomes according to preoperative mental illness category. Electronic health record data from several US healthcare systems were used to compare outcomes of four groups of patients who underwent bariatric surgery in 2012 and 2013. These included the following: people with (1) no mental illness, (2) mild-to-moderate depression or anxiety, (3) severe depression or anxiety, and (4) bipolar, psychosis, or schizophrenia spectrum disorders. Groups were compared on weight loss trajectory using generalized estimating equations using B-spline bases and on all-cause emergency department visits and hospital days using zero-inflated Poisson and negative binomial regression up to 2 years after surgery. Models were adjusted for demographic and health covariates, including baseline healthcare use. Among 8,192 patients, mean age was 44.3 (10.7) years, 79.9% were female, and 45.6% were white. Fifty-seven percent had preoperative mental illness. There were no differences between groups for weight loss, but patients with preoperative severe depression or anxiety or bipolar, psychosis, or schizophrenia spectrum disorders had higher follow-up levels of emergency department visits and hospital days compared to those with no mental illness. In this multicenter study, mental illness was not associated with differential weight loss after bariatric surgery, but additional research could focus on reducing acute care use among these patients. © 2017 The Obesity Society.

    This paper proposes the idea that a large proportion of the incidents attributed to operator and maintenance error in a nuclear or industrial plant are actually founded in our human emotions. Basic psychological theory of emotions is briefly presented and then the authors present situations and instances that can cause emotions to swell and lead to operator and maintenance error. Since emotional information is not recorded in industrial incident reports, the challenge is extended to industry, to review incident source documents for cases of emotional involvement and to develop means to collect emotion related information in future root cause analysis investigations. Training must then be provided to operators and maintainers to enable them to know one's emotions, manage emotions, motivate one's self, recognize emotions in others and handle relationships. Effective training will reduce the instances of human error based in emotions and enable a cooperative, productive environment in which to work. (author)

    Background For most rural households in sub-Saharan Africa, healthy livestock play a key role in averting the burden associated with zoonotic diseases, and in meeting household nutritional and socio-economic needs. However, there is limited understanding of the complex nutritional, socio-economic, and zoonotic pathways that link livestock health to human health and welfare. Here we describe a platform for integrated human health, animal health and economic welfare analysis designed to address this challenge. We provide baseline epidemiological data on disease syndromes in humans and the animals they keep, and provide examples of relationships between human health, animal health and household socio-economic status. Method We designed a study to obtain syndromic disease data in animals along with economic and behavioral information for 1500 rural households in Western Kenya already participating in a human syndromic disease surveillance study. Data collection started in February 2013, and each household is visited bi-weekly and data on four human syndromes (fever, jaundice, diarrhea and respiratory illness) and nine animal syndromes (death, respiratory, reproductive, musculoskeletal, nervous, urogenital, digestive, udder disorders, and skin disorders in cattle, sheep, goats and chickens) are collected. Additionally, data from a comprehensive socio-economic survey is collected every 3 months in each of the study households. Findings Data from the first year of study showed 93% of the households owned at least one form of livestock (55%, 19%, 41% and 88% own cattle, sheep, goats and chickens respectively). Digestive disorders, mainly diarrhea episodes, were the most common syndromes observed in cattle, goats and sheep, accounting for 56% of all livestock syndromes, followed by respiratory illnesses (18%). In humans, respiratory illnesses accounted for 54% of all illnesses reported, followed by acute febrile illnesses (40%) and diarrhea illnesses (5%). While controlling

    Full Text Available Recent advances in biosensor design and sensing efficacy need to be amalgamated with research in responsive drug delivery systems for building superior health or illness regimes and ensuring good patient compliance. A variety of illnesses require continuous monitoring in order to have efficient illness intervention. Physicochemical changes in the body can signify the occurrence of an illness before it manifests. Even with the usage of sensors that allow diagnosis and prognosis of the illness, medical intervention still has its downfalls. Late detection of illness can reduce the efficacy of therapeutics. Furthermore, the conventional modes of treatment can cause side-effects such as tissue damage (chemotherapy and rhabdomyolysis and induce other forms of illness (hepatotoxicity. The use of drug delivery systems enables the lowering of side-effects with subsequent improvement in patient compliance. Chronic illnesses require continuous monitoring and medical intervention for efficient treatment to be achieved. Therefore, designing a responsive system that will reciprocate to the physicochemical changes may offer superior therapeutic activity. In this respect, integration of biosensors and drug delivery is a proficient approach and requires designing an implantable system that has a closed loop system. This offers regulation of the changes by means of releasing a therapeutic agent whenever illness biomarkers prevail. Proper selection of biomarkers is vital as this is key for diagnosis and a stimulation factor for responsive drug delivery. By detecting an illness before it manifests by means of biomarkers levels, therapeutic dosing would relate to the severity of such changes. In this review various biosensors and drug delivery systems are discussed in order to assess the challenges and future perspectives of integrating biosensors and drug delivery systems for detection and management of chronic illness.

    The ethnographic study was conducted in two communities in Oyo State in Southwestern Nigeria. The study sites consisted of a rural and an urban local government area located in the tropical rain forest zone of Nigeria. The study was designed to obtain information on febrile illnesses and herbal remedies for treatment with the aim of identifying potential antimalarial drugs. The study revealed that fever is a general term for describing illnesses associated with elevated body temperature. The indigenous Yoruba ethnic population has categorized fever based on symptoms and causes. The present communication is the result of focus group discussion and semi-structured questionnaire administered to traditional healers, herb sellers, elders and mothers. This was on types of fevers, symptoms and causes of febrile illnesses. The investigation also included use of traditional herbs in the prevention and treatment of the illnesses in the two communities.A total of 514 respondents were interviewed. This was made up of 266 (51.8%) from Atiba local government area (LGA), an urban centre while 248 (48.2%) respondents were interviewed from Itesiwaju LGA, a rural community. The LGAs are located in Oyo State of Nigeria. The respondents proffered 12 types of febrile illnesses in a multiple response answering system in Yoruba language. The most common ones (direct translation into English) were: yellow fever (39.1%), typhoid (34.8%), ordinary (28.8%), rainy season (20.8%) and headache (10.5%) fevers, respectively. Perceived causes of each of the febrile illnesses included stress, mosquito bites, unclean water, rains and over exposure to the sun. Methods of fever prevention were mainly with the use of herbal decoctions, powdered herbs, orthodox medications and maintenance of proper hygiene. Of a total of 112 different herbal remedies used in the treatment of the febrile illnesses compiled from the study, 25 recipes are presented. Recipes consisted of 2-7 ingredients.

    Full Text Available Adenovirus infection can cause various illnesses depending on the infecting serotype, such as gastroenteritis, conjunctivitis, cystitis, and rash illness, but the infection mechanism is still unknown. MicroRNAs (miRNA have been reported to play essential roles in cell proliferation, cell differentiation, and pathogenesis of human diseases including viral infections. We analyzed the miRNA expression profiles from adenovirus type 3 (AD3 infected Human laryngeal epithelial (Hep2 cells using a SOLiD deep sequencing. 492 precursor miRNAs were identified in the AD3 infected Hep2 cells, and 540 precursor miRNAs were identified in the control. A total of 44 miRNAs demonstrated high expression and 36 miRNAs showed lower expression in the AD3 infected cells than control. The biogenesis of miRNAs has been analyzed, and some of the SOLiD results were confirmed by Quantitative PCR analysis. The present studies may provide a useful clue for the biological function research into AD3 infection.

    Within the United States, elevated levels of fecal indicator bacteria (FIB) remain the leading cause of surface water-quality impairments requiring formal remediation plans under the federal Clean Water Act's Total Maximum Daily Load (TMDL) program. The sufficiency of compliance with numerical FIB criteria as the targeted endpoint of TMDL remediation plans may be questionable given poor correlations between FIB and pathogenic microorganisms and varying degrees of risk associated with exposure to different fecal pollution sources (e.g. human vs animal). The present study linked a watershed-scale FIB fate and transport model with a dose-response model to continuously predict human health risks via quantitative microbial risk assessment (QMRA), for comparison to regulatory benchmarks. This process permitted comparison of risks associated with different fecal pollution sources in an impaired urban watershed in order to identify remediation priorities. Results indicate that total human illness risks were consistently higher than the regulatory benchmark of 36 illnesses/1000 people for the study watershed, even when the predicted FIB levels were in compliance with the Escherichia coli geometric mean standard of 126CFU/100mL. Sanitary sewer overflows were associated with the greatest risk of illness. This is of particular concern, given increasing indications that sewer leakage is ubiquitous in urban areas, yet not typically fully accounted for during TMDL development. Uncertainty analysis suggested the accuracy of risk estimates would be improved by more detailed knowledge of site-specific pathogen presence and densities. While previous applications of the QMRA process to impaired waterways have mostly focused on single storm events or hypothetical situations, the continuous modeling framework presented in this study could be integrated into long-term water quality management planning, especially the United States' TMDL program, providing greater clarity to watershed

    Full Text Available Elevated intraocular pressure (IOP is a major risk factor for glaucoma. One consequence of raised IOP is that ocular tissues are subjected to increased hydrostatic pressure (HP. The effect of raised HP on stress pathway signaling and retinal ganglion cell (RGC survival in the human retina was investigated.A chamber was designed to expose cells to increased HP (constant and fluctuating. Accurate pressure control (10-100 mmHg was achieved using mass flow controllers. Human organotypic retinal cultures (HORCs from donor eyes (<24 h post mortem were cultured in serum-free DMEM/HamF12. Increased HP was compared to simulated ischemia (oxygen glucose deprivation, OGD. Cell death and apoptosis were measured by LDH and TUNEL assays, RGC marker expression by qRT-PCR (THY-1 and RGC number by immunohistochemistry (NeuN. Activated p38 and JNK were detected by Western blot.Exposure of HORCs to constant (60 mmHg or fluctuating (10-100 mmHg; 1 cycle/min pressure for 24 or 48 h caused no loss of structural integrity, LDH release, decrease in RGC marker expression (THY-1 or loss of RGCs compared with controls. In addition, there was no increase in TUNEL-positive NeuN-labelled cells at either time-point indicating no increase in apoptosis of RGCs. OGD increased apoptosis, reduced RGC marker expression and RGC number and caused elevated LDH release at 24 h. p38 and JNK phosphorylation remained unchanged in HORCs exposed to fluctuating pressure (10-100 mmHg; 1 cycle/min for 15, 30, 60 and 90 min durations, whereas OGD (3 h increased activation of p38 and JNK, remaining elevated for 90 min post-OGD.Directly applied HP had no detectable impact on RGC survival and stress-signalling in HORCs. Simulated ischemia, however, activated stress pathways and caused RGC death. These results show that direct HP does not cause degeneration of RGCs in the ex vivo human retina.

    Background Studies of influenza vaccine effectiveness in schools have assessed all-cause absenteeism rather than laboratory-confirmed influenza. We conducted an observational pilot study to identify absences due to respiratory illness and laboratory-confirmed influenza in schools with and without school-based vaccination. Methods A local public health agency initiated school-based influenza vaccination in two Wisconsin elementary schools during October 2010 (exposed schools); two nearby schools served as a comparison group (non-exposed schools). Absences due to fever or cough illness were monitored for 12 weeks. During the 4 weeks of peak influenza activity, parents of absent children with fever/cough illness were contacted and offered influenza testing. Results Parental consent for sharing absenteeism data was obtained for 937 (57%) of 1,640 students. Fifty-two percent and 28%, respectively, of all students in exposed and non-exposed schools were vaccinated. Absences due to fever or cough illness were significantly lower in the exposed schools during seven of 12 surveillance weeks. Twenty-seven percent of students at exposed schools and 39% at unexposed schools had one or more days of absence due to fever/cough illness (pabsenteeism due to fever or cough illness, but not absenteeism for other reasons. Although nonspecific, absence due to fever or cough illness may be a useful surrogate endpoint in school-based studies if identification of laboratory confirmed influenza is not feasible.

    Human metapneumovirus (HMPV) was identified in 2001 and is a common cause of acute respiratory illness in young children. The radiologic characteristics of laboratory-confirmed HMPV acute respiratory illness in young children have not been systematically assessed. We systematically evaluated the radiographic characteristics of acute respiratory illness associated with HMPV in a prospective cohort of pediatric patients. We included chest radiographs from children <5 years old with acute respiratory illness who were enrolled in the prospective New Vaccine Surveillance Network (NVSN) study from 2003 to 2009 and were diagnosed with HMPV by reverse transcription-polymerase chain reaction (RT-PCR). Of 215 HMPV-positive subjects enrolled at our tertiary care children's hospital, 68 had chest radiographs obtained by the treating clinician that were available for review. Two fellowship-trained pediatric radiologists, independently and then in consensus, retrospectively evaluated these chest radiographs for their radiographic features. Parahilar opacities were the most commonly observed abnormality, occurring in 87% of children with HMPV. Hyperinflation also occurred frequently (69%). Atelectasis (40%) and consolidation (18%) appeared less frequently. Pleural effusion and pneumothorax were not seen on any radiographs. The clinical presentations of HMPV include bronchiolitis, croup and pneumonia. Dominant chest radiographic abnormalities include parahilar opacities and hyperinflation, with occasional consolidation. Recognition of the imaging patterns seen with common viral illnesses like respiratory syncytial virus (RSV) and HMPV might facilitate diagnosis and limit unnecessary antibiotic treatment. (orig.)

    Acid-base imbalances observed in human paediatric patients are associated with outcome. Likewise, neonatal foals may have different acid-base imbalances associated with diagnosis or prognosis. To determine acid-base imbalances by the quantitative method in ill neonatal foals and assess their association with diagnosis and prognosis. Observational prospective clinical study. This study included 65 ill neonatal foals (32 septic, 33 nonseptic) admitted to an equine referral hospital from 2005 to 2011with acid-base parameters determined on admission and a control group of 33 healthy neonatal foals. Blood pH, pCO 2 , sodium, potassium, chloride, L-lactate, albumin and phosphate concentrations were determined. Bicarbonate, globulin, measured strong ion difference (SID m ), nonvolatile weak buffer concentrations (A tot ), base excess and its components were calculated. Analysis of covariance (ANCOVA) and multiple linear regression statistical analyses were performed. Results are summarised as mean ± s.d. for normally distributed variables and median [25-75th percentiles] for non-normally distributed ones. A total of 63% of ill foals had respiratory alkalosis and 58.5% had SID m acidosis. The combination of both alterations was detected in 21 of 65 ill foals and abnormal pH was found in 24 of 65. Compared with healthy foals, ill foals had significantly lower SID m (nonseptic 31.6 ± 6.3 [Pacid-base imbalances observed in ill foals were respiratory alkalosis, SID m acidosis or mixed respiratory alkalosis with strong ion acidosis.

    To summarize the current literature on racial and gender disparities in critical care and the mechanisms underlying these disparities in the course of acute critical illness. MEDLINE search on the published literature addressing racial, ethnic, or gender disparities in acute critical illness, such as sepsis, acute lung injury, pneumonia, venous thromboembolism, and cardiac arrest. Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities. Study findings are presented according to their association with the prevalence, clinical presentation, management, and outcomes in acute critical illness. This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data are organized along the course of acute critical illness. The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research.

    Full Text Available Abstract Background Stigma and discrimination associated with mental illness are strongly linked to suffering, disability and poverty. In order to protect the rights of those with mental disorders and to sensitively develop services, it is vital to gain a more accurate understanding of the frequency and nature of stigma against people with mental illness. Little research about this issue has been conducted in Sub- Saharan Africa. Our study aimed to describe levels of stigma in Malawi. Methods A cross-sectional survey of patients and carers attending mental health and non-mental health related clinics in a general hospital in Blantyre, Malawi. Participants were interviewed using an adapted version of the questionnaire developed for the “World Psychiatric Association Program to Reduce Stigma and Discrimination Because of Schizophrenia”. Results 210 participants participated in our study. Most attributed mental disorder to alcohol and illicit drug abuse (95.7%. This was closely followed by brain disease (92.8%, spirit possession (82.8% and psychological trauma (76.1%. There were some associations found between demographic variables and single question responses, however no consistent trends were observed in stigmatising beliefs. These results should be interpreted with caution and in the context of existing research. Contrary to the international literature, having direct personal experience of mental illness seemed to have no positive effect on stigmatising beliefs in our sample. Conclusions Our study contributes to an emerging picture that individuals in Sub-Saharan Africa most commonly attribute mental illness to alcohol/ illicit drug use and spirit possession. Our work adds weight to the argument that stigma towards mental illness is an important global health and human rights issue.

    A simple non-parametric approach is developed to simultaneously estimate net incidence and morbidity time from specific AIDS illnesses in populations at high risk for death from these illnesses and other causes. The disease-death process has four-stages that can be recast as two sandwiching three-state multiple decrement processes. Non-parametric estimation of net incidence and morbidity time with error bounds are achieved from these sandwiching models through modification of methods from Aalen and Greenwood, and bootstrapping. An application to immunosuppressed HIV-1 infected homosexual men reveals that cytomegalovirus disease, Kaposi's sarcoma and Pneumocystis pneumonia are likely to occur and cause significant morbidity time.

  10. Rapamycin causes growth arrest and inhibition of invasion in human chondrosarcoma cells.

    2016-01-01

    Chondrosarcoma is a highly malignant tumor that is characterized by a potent capacity to invade locally and cause distant metastasis and notable for its lack of response to conventional chemotherapy or radiotherapy. Rapamycin, the inhibitor of mammalian target of rapamycin (mTOR), is a valuable drug with diverse clinical applications and regulates many cellular processes. However, the effects of rapamycin on cell growth and invasion of human chondrosarcoma cells are not well known. We determined the effect of rapamycin on cell proliferation, cell cycle arrest and invasion by using MTS, flow cytometry and invasion assays in two human chondrosarcoma cell lines, SW1353 and JJ012. Cell cycle regulatory and invasion-related genes' expression analysis was performed by quantitative RT-PCR (qRT-PCR). We also evaluated the effect of rapamycin on tumor growth by using mice xenograph models. Rapamycin significantly inhibited the cell proliferation, induced cell cycle arrest and decreased the invasion ability of human chondrosarcoma cells. Meanwhile, rapamycin modulated the cell cycle regulatory and invasion-related genes' expression. Furthermore, the tumor growth of mice xenograph models with human chondrosarcoma cells was significantly inhibited by rapamycin. These results provided further insight into the role of rapamycin in chondrosarcoma. Therefore, rapamycin targeted therapy may be a potential treatment strategy for chondrosarcoma.

  11. Can Artificial Intelligences Suffer from Mental Illness? A Philosophical Matter to Consider.

    2017-04-01

    The potential for artificial intelligences and robotics in achieving the capacity of consciousness, sentience and rationality offers the prospect that these agents have minds. If so, then there may be a potential for these minds to become dysfunctional, or for artificial intelligences and robots to suffer from mental illness. The existence of artificially intelligent psychopathology can be interpreted through the philosophical perspectives of mental illness. This offers new insights into what it means to have either robot or human mental disorders, but may also offer a platform on which to examine the mechanisms of biological or artificially intelligent psychiatric disease. The possibility of mental illnesses occurring in artificially intelligent individuals necessitates the consideration that at some level, they may have achieved a mental capability of consciousness, sentience and rationality such that they can subsequently become dysfunctional. The deeper philosophical understanding of these conditions in mankind and artificial intelligences might therefore offer reciprocal insights into mental health and mechanisms that may lead to the prevention of mental dysfunction.

    2016-08-04

    Rapid growth and development in recent decades has seen mental health and mental illness emerge as priority health concerns for the Gulf Cooperation Council (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates). As a result, mental health services in the region are being redefined and expanded. However, there is a paucity of local research to guide ongoing service development. Local research is important because service users' experience of mental illness and mental health services are linked to their sociocultural context. In order for service development to be most effective, there is a need for increased understanding of the people who use these services.This article aims to review and synthesize mental health research from the Gulf Cooperation Council. It also seeks to identify gaps in the literature and suggest directions for future research. A scoping framework was used to conduct this review. To identify studies, database searches were undertaken, regional journals were hand-searched, and reference lists of included articles were examined. Empirical studies undertaken in the Gulf Cooperation Council that reported mental health service users' experience of mental illness were included. Framework analysis was used to synthesize results. Fifty-five studies met inclusion criteria and the following themes were identified: service preferences, illness (symptomology, perceived cause, impact), and recovery (traditional healing, family support, religion). Gaps included contradictory findings related to the supportive role of the Arabic extended family and religion, under-representation of women in study samples, and limited attention on illness management outside of the hospital setting.From this review, it is clear that the sociocultural context in the region is linked to service users' experience of mental illness. Future research that aims to fill the identified gaps and develop and test culturally appropriate interventions will aid practice

    Full Text Available Objectives & Methods: This suggestion was attempted to be elevated the recognition of common characteristics in disease. So, we performed to analyze the correlation of common cause of disease, characteristics of human body, and medical treatment. And the results are as follows. Results: 1. The cause of disease is consist of genetic factor, aging, habit, food of not good in health, weather, environment, deficit of the physical activity, stress and so on. 2. Generally, human has common and individual weakness. Individual weakness is appeared similar to the occurrence of volcano and lapse. 3. The correlation of disease and medical treatments is possible to explain using the quotation of the law of motion made by Isaac Newton, the great physicist. 4. When the process of the medical treatment was not progressed, the prognosis is determined by the correlation of the homeostasis(H' in human body and the homeostasis(H of disease. 5. The prognosis of disease is determined by the relationship between the energy of disease(F and medical treatment(F'. 6. The exact diagnosis is possible to predict the treatment sequence, and the facts that homeostasis in human body and disease, relationship between the energy of disease(F and medical treatment(F', action and reaction are important to determine the prognosis. 7. The careful observation of improving response and worsening action of disease becomes available for exact prognosis. Conclusion: The above described contents may be useful in clinical studies, and the concrete clinical reports about this will be made afterward.

    Background Enteropathogenic Yersinia circulate in the pig reservoir and are the third bacterial cause of human gastrointestinal infections in Europe. In West Africa, reports of human yersiniosis are rare. This study was conducted to determine whether pathogenic Yersinia are circulating in pig farms and are responsible for human infections in the Abidjan District. Methodology/Principal findings From June 2012 to December 2013, pig feces were collected monthly in 41 swine farms of the Abidjan district. Of the 781 samples collected, 19 Yersinia strains were isolated in 3 farms: 7 non-pathogenic Yersinia intermedia and 12 pathogenic Yersinia enterocolitica bioserotype 4/O:3. Farm animals other than pigs and wild animals were not found infected. Furthermore, 2 Y. enterocolitica 4/O:3 strains were isolated from 426 fecal samples of patients with digestive disorders. All 14 Y. enterocolitica strains shared the same PFGE and MLVA profile, indicating their close genetic relationship. However, while 6 of them displayed the usual phage type VIII, the other 8 had the highly infrequent phage type XI. Whole genome sequencing and SNP analysis of individual colonies revealed that phage type XI strains had unusually high rates of mutations. These strains displayed a hypermutator phenotype that was attributable to a large deletion in the mutS gene involved in DNA mismatch repair. Conclusions/Significance This study demonstrates that pathogenic Y. enterocolitica circulate in the pig reservoir in Côte d'Ivoire and cause human infections with a prevalence comparable to that of many developed countries. The paucity of reports of yersiniosis in West Africa is most likely attributable to a lack of active detection rather than to an absence of the microorganism. The identification of hypermutator strains in pigs and humans is of concern as these strains can rapidly acquire selective advantages that may increase their fitness, pathogenicity or resistance to commonly used treatments.

    It is well known that people with severe mental illness have a reduced life expectancy and a greater risk of being affected by preventable physical illnesses such as metabolic syndrome, cardiovascular disease and type 2 diabetes. There are still, however, only a few published studies focusing on what enables healthy living for this group. This study thus aimed to describe what enables healthy living among people with severe mental illness in psychiatric outpatient services. The data were collected in qualitative interviews (n = 16) and content analysis was used to analyze the data. The interviews resulted in an overall theme "Being regarded as a whole human being by self and others", which showed the multidimensional nature of health and the issues that enable healthy living among people with severe mental illness. Three categories emerged: (i) everyday structure (ii), motivating life events and (iii) support from significant others. The results indicate that a person with severe mental illness needs to be encountered as a whole person if healthy living is to be enabled. Attaining healthy living requires collaboration between the providers of care, help and support. Health care organizations need to work together to develop and provide interventions to enable healthy living and to reduce poor physical health among people with severe mental illness. © 2017 Australian College of Mental Health Nurses Inc.

    People with intellectual disabilities face a much greater burden and earlier onset of physical and mental ill-health than the general adult population. Physical-mental comorbidity has been shown to result in poorer outcomes in the general population, but little is known about this relationship in adults with intellectual disabilities. To identify whether physical ill-health is associated with mental ill-health in adults with intellectual disabilities and whether the extent of physical multi-morbidity can predict the likelihood of mental ill-health. To identify any associations between types of physical ill-health and mental ill-health. A total of 1023 adults with intellectual disabilities underwent comprehensive health assessments. Binary logistic regressions were undertaken to establish any association between the independent variables: total number of physical health conditions, physical conditions by International Classification of Disease-10 chapter and specific physical health conditions; and the dependent variables: problem behaviours, mental disorders of any type. All regressions were adjusted for age, gender, level of intellectual disabilities, living arrangements, neighbourhood deprivation and Down syndrome. The extent of physical multi-morbidity was not associated with mental ill-health in adults with intellectual disabilities as only 0.8% of the sample had no physical conditions. Endocrine disease increased the risk of problem behaviours [odds ratio (OR): 1.22, 95% confidence interval (CI): 1.02-1.47], respiratory disease reduced the risk of problem behaviours (OR: 0.73, 95% CI: 0.54-0.99) and mental ill-health of any type (OR: 0.73, 95% CI: 0.58-0.92), and musculoskeletal disease reduced the risk of mental ill-health of any type (OR: 0.84, 95% CI: 0.73-0.98). Ischaemic heart disease increased the risk of problem behaviours approximately threefold (OR: 3.29, 95% CI: 1.02-10.60). The extent of physical multi-morbidity in the population with intellectual

    Full Text Available Abstract Background Human parainfluenza viruses (HPIVs are important causes of upper respiratory tract illness (URTI and lower respiratory tract illness (LRTI. To analyse epidemiologic and clinical characteristics of the four types of human parainfluenza viruses (HPIVs, patients with acute respiratory tract illness (ARTI were studied in Guangzhou, southern China. Methods Throat swabs (n=4755 were collected and tested from children and adults with ARTI over a 26-month period, and 4447 of 4755 (93.5% patients’ clinical presentations were recorded for further analysis. Results Of 4755 patients tested, 178 (3.7% were positive for HPIV. Ninety-nine (2.1% samples were positive for HPIV-3, 58 (1.2% for HPIV-1, 19 (0.4% for HPIV-2 and 8 (0.2% for HPIV-4. 160/178 (88.9% HPIV-positive samples were from paediatric patients younger than 5 years old, but no infant under one month of age was HPIV positive. Seasonal peaks of HPIV-3 and HPIV-1 occurred as autumn turned to winter and summer turned to autumn. HPIV-2 and HPIV-4 were detected less frequently, and their frequency of isolation increased when the frequency of HPIV-3 and HPIV-1 declined. HPIV infection led to a wide spectrum of symptoms, and more “hoarseness” (p=0.015, “abnormal pulmonary breathing sound” (p Conclusions HPIV infection led to a wide spectrum of symptoms, and similar clinical manifestations were found in the patients with four different types of HPIVs. The study suggested pathogenic activity of HPIV in gastrointestinal illness. The clinical presentation of HPIV infection may differ by patient age.

    Psychosocial distress among patients with limited life expectancy influences treatment decisions, treatment adherence, and physical health. Veterans may be at elevated risk of psychosocial distress at the end of life, and understanding their mental healthcare needs may help identify hospitalized patients to whom psychiatric services should be targeted. To examine mental illness prevalence and mental health treatment rates among a national sample of hospitalized veterans with serious physical illnesses. Design, Subjects, and Measurements: This was a retrospective study of 11,286 veterans hospitalized in a Veterans Health Administration acute care facility in fiscal year 2011 with diagnoses of advanced cancer, congestive heart failure, chronic obstructive pulmonary disease, and/or advanced HIV/AIDS. Prevalent and incident mental illness diagnoses during and before hospitalization and rates of psychotherapy and psychotropic use among patients with incident depression and anxiety were measured. At least one-quarter of the patients in our sample had a mental illness or substance use disorder. The most common diagnoses at hospitalization were depression (11.4%), followed by alcohol abuse or dependence (5.5%), and post-traumatic stress disorder (4.9%). Of the 831 patients with incident past-year depression and 258 with incident past-year anxiety, nearly two-thirds received at least some psychotherapy or guideline-concordant medication within 90 days of diagnosis. Of 191 patients with incident depression and 47 with incident anxiety at time of hospitalization, fewer than half received mental healthcare before discharge. Many veterans hospitalized with serious physical illnesses have comorbid mental illnesses and may benefit from depression and anxiety treatment.

  1. Estimating the global burden of thalassogenic diseases: human infectious diseases caused by wastewater pollution of the marine environment.

    2003-06-01

    This paper presents a preliminary attempt at obtaining an order-of-magnitude estimate of the global burden of disease (GBD) of human infectious diseases associated with swimming/bathing in coastal waters polluted by wastewater, and eating raw or lightly steamed filter-feeding shellfish harvested from such waters. Such diseases will be termed thalassogenic--caused by the sea. Until recently these human health effects have been viewed primarily as local phenomena, not generally included in the world agenda of marine scientists dealing with global marine pollution problems. The massive global scale of the problem can be visualized when one considers that the wastewater and human body wastes of a significant portion of the world's population who reside along the coastline or in the vicinity of the sea are discharged daily, directly or indirectly, into the marine coastal waters, much of it with little or no treatment. Every cubic metre of raw domestic wastewater discharged into the sea can carry millions of infectious doses of pathogenic microorganisms. It is estimated that globally, foreign and local tourists together spend some 2 billion man-days annually at coastal recreational resorts and many are often exposed there to coastal waters polluted by wastewater. Annually some 800 million meals of potentially contaminated filter-feeding shellfish/bivalves and other sea foods, harvested in polluted waters are consumed, much of it raw or lightly steamed. A number of scientific studies have shown that swimmers swallow significant amounts of polluted seawater and can become ill with gastrointestinal and respiratory diseases from the pathogens they ingest. Based on risk assessments from the World Health Organization (WHO) and academic research sources the present study has made an estimate that globally, each year, there are in excess of 120 million cases of gastrointestinal disease and in excess of 50 million cases of more severe respiratory diseases caused by swimming and

    After the return of Spain to democracy and the regional assumption of government powers, actions were initiated to improve the mortality statistics of death causes. The objective of this work was to describe the evolution of the quality activities improvements into the statistics of death causes on Murcia's region during 1989 to 2011. Descriptive epidemiological study of all death documents processed by the Murcia mortality registry. Use of indicators related to the quality of the completion of death in medical and judicial notification; recovery of information on the causes and circumstances of death; and impact on the statistics of ill-defined, unspecific and less specific causes. During the study period, the medical notification without a temporary sequence on the death certificate (DC) has decreased from 46% initial to 21% final (p less than 0.001). Information retrieval from sources was successful in 93% of the cases in 2001 compared to 38%, at the beginning of the period (p less than 0.001). Regional rates of ill-defined and unspecific causes fell more than national ones, and they were in the last year with a differential of 10.3 (p less than 0.001) and 2.8 points (p=0.001), respectively. The medical death certification improved in form and suitability. Regulated recovery of the causes of death and circumstances corrected medical and judicial information. The Murcia's region presented lower rates in less specified causes and ill-defined entities than national averages.

  3. Prevalence and consequences of the dual diagnosis of substance abuse and severe mental illness.

    Buckley, Peter F

    2006-01-01

    The co-occurrence of a severe mental illness and a substance use or abuse disorder is common in the United States as well as internationally and could be considered as more the expectation than the exception when assessing patients with serious mental illness. Substance use disorders can occur at any phase of the mental illness, perhaps even inducing psychosis. Causes of this comorbidity may include self-medication, genetic vulnerability, environment or lifestyle, underlying shared origins, and/or a common neural substrate. The consequences of dual diagnosis include poor medication compliance, physical comorbidities and poor health, poor self-care, increased suicide risk or aggression, increased sexual behavior, and possible incarceration. All of these factors contribute to a greater health burden, which reduces the health care system's capacity to adequately treat patients. Therefore, screening, assessment, and integrated treatment plans for dual diagnosis that can address both the addiction disorder and the mental illness are recommended in order to provide accurate treatment, after-care, and other health care to accommodate patients' social and vocational needs.

    The aim of the present study was to examine whether profiles of illness perceptions are associated with 10-year survival following cardiac valve replacement surgery. Illness perceptions were evaluated in 204 cardiac patients awaiting first-time valve replacement and again 1 year post-operatively using cluster analysis. All-cause mortality was recorded over a 10-year period. At 1 year, 136 patients were grouped into one of four profiles (stable positive, stable negative, changed from positive to negative, changed from negative to positive). The median follow-up was 3063 days (78 deaths). After controlling for clinical covariates, including markers of function, patients who changed illness perceptions from positive to negative beliefs 1 year post-surgery had an increased mortality risk (hazard ratio (HR) = 3.2, 95% confidence interval (CI) 1.2-8.3, p = .02) compared to patients who held positive stable perceptions. Following cardiac valve replacement, developing negative illness perceptions over the first post-operative year predicts long-term mortality. Early screening and intervention to alter this pattern of beliefs may be beneficial.

    Full Text Available In spite of the strong role of traditional medicine in childcare in the pluralistic healthcare system in Western Africa, little information is known on mothers' domestic plant knowledge. Identifying local perspectives and treatments of children's illnesses, including folk illnesses, is essential to having a comprehensive understanding of how mothers make healthcare treatment decisions. We aimed to identify which infant illnesses Beninese and Gabonese mothers knew to treat with medicinal plants and for which illnesses they sought biomedical care or traditional healers.We conducted 81 questionnaires with mothers in Bénin and Gabon and made 800 botanical specimens of cited medicinal plants. We calculated the number of species cited per illness and the proportion of participants knowledgeable on at least one herbal remedy per illness. Using qualitative data, we described folk illnesses in each country and summarized responses on preferences for each of the three healthcare options.Participants from both countries were most knowledgeable on plants to treat respiratory illnesses, malaria, diarrhea, and intestinal ailments. Mothers also frequently mentioned the use of plants to encourage children to walk early, monitor the closure of fontanels, and apply herbal enemas. Major folk illnesses were atita and ka in Bénin and la rate and fesses rouges in Gabon. Traditional healers were reported to have specialized knowledge of cultural bound illnesses. Malaria was frequently cited as an illness for which mothers would directly seek biomedical treatment.Mothers largely saw the three systems as complementary, seamlessly switching between different healing options until a remedy was found. Folk illnesses were found to give insight into local treatments and may reveal important neglected diseases. Due to high reported levels of knowledge on treating top statistical causes of infant mortality and folk illnesses, mothers' medicinal plant knowledge should be

    Mental health symptoms (MHSs) may affect people's work capacity and lead to sickness absence and disability. Expectations and perceptions of illness have been shown to influence return to work (RTW) across health conditions, but we know little about illness perceptions and RTW-expectations in MHSs. The aim of this study was to investigate the association between illness perceptions and RTW-expectations in a group struggling with work participation due to MHSs. Cross-sectional associations between illness perceptions and return to work expectations at baseline were analyzed for 1,193 participants who reported that MHSs affected their work participation. The study was part of a randomized controlled trial evaluating the effect of job focused Cognitive Behavioral Therapy (CBT) combined with supported employment (IPS). Participants were from a working age population with diverse job status. There was a strong and salient relationship between illness perceptions and RTW-expectations. When adjusting for demographic and clinical variables, the components consequences, personal control, identity and illness concern remained significantly associated with uncertain and negative RTW-expectations. Less illness understanding remained significantly associated with uncertain RTW-expectations, while timeline and emotional representations remained significantly associated with negative RTW-expectations. In the fully adjusted model only the consequences component (believing that illness has more severe consequences) remained significantly associated with RTW-expectations. Openly asked, participants reported work, personal relationships and stress as main causes of their illness. In people with MHSs who struggle with work participation, perceptions and beliefs about their problems are strongly associated with their expectations to return to work.

    Contact currents flow from/into a human body when touching an object such as a metal structure with a different electric potential. These currents can stimulate muscle and peripheral nerves. In this context, computational analyses of in situ electric fields caused by the contact current have been performed, while their effectiveness for transient contact currents has not well been investigated. In the present study, using an anatomically based human model, a dispersive finite-difference time-domain model was utilised to computed transient contact current and in situ electric fields from a charged human. Computed in situ electric fields were highly localised in the hand. In order to obtain an insight into the relationship between in situ electric field and electro-stimulation, cell-maximum and 5-mm averaged in situ electric fields were computed and compared with strength-duration curves. The comparison suggests that both measures could be larger than thresholds derived from the strength- duration curves with parameters used in previous studies. (authors)

    Environmental histories that span the last full glacial cycle and are representative of regional change in Australia are scarce, hampering assessment of environmental change preceding and concurrent with human dispersal on the continent ca. 47,000 years ago. Here we present a continuous 150,000-year record offshore south-western Australia and identify the timing of two critical late Pleistocene events: wide-scale ecosystem change and regional megafaunal population collapse. We establish that substantial changes in vegetation and fire regime occurred ∼70,000 years ago under a climate much drier than today. We record high levels of the dung fungus Sporormiella, a proxy for herbivore biomass, from 150,000 to 45,000 years ago, then a marked decline indicating megafaunal population collapse, from 45,000 to 43,100 years ago, placing the extinctions within 4,000 years of human dispersal across Australia. These findings rule out climate change, and implicate humans, as the primary extinction cause. PMID:28106043

    Plague is a life-threatening disease caused by the bacterium, Yersinia pestis. Since the 1990s, Africa has accounted for the majority of reported human cases. In Uganda, plague cases occur in the West Nile region, near the border with Democratic Republic of Congo. Despite the ongoing risk of contracting plague in this region, little is known about Y. pestis genotypes causing human disease. During January 2004-December 2012, 1,092 suspect human plague cases were recorded in the West Nile region of Uganda. Sixty-one cases were culture-confirmed. Recovered Y. pestis isolates were analyzed using three typing methods, single nucleotide polymorphisms (SNPs), pulsed field gel electrophoresis (PFGE), and multiple variable number of tandem repeat analysis (MLVA) and subpopulations analyzed in the context of associated geographic, temporal, and clinical data for source patients. All three methods separated the 61 isolates into two distinct 1.ANT lineages, which persisted throughout the 9 year period and were associated with differences in elevation and geographic distribution. We demonstrate that human cases of plague in the West Nile region of Uganda are caused by two distinct 1.ANT genetic subpopulations. Notably, all three typing methods used, SNPs, PFGE, and MLVA, identified the two genetic subpopulations, despite recognizing different mutation types in the Y. pestis genome. The geographic and elevation differences between the two subpopulations is suggestive of their maintenance in highly localized enzootic cycles, potentially with differing vector-host community composition. This improved understanding of Y. pestis subpopulations in the West Nile region will be useful for identifying ecologic and environmental factors associated with elevated plague risk.

    Tyrosinase (TYR) catalyzes the rate-limiting, first step in melanin production and its gene (TYR) is mutated in many cases of oculocutaneous albinism (OCA1), an autosomal recessive cause of childhood blindness. Patients with reduced TYR activity are classified as OCA1B; some OCA1B mutations are temperature-sensitive. Therapeutic research for OCA1 has been hampered, in part, by the absence of purified, active, recombinant wild-type and mutant human enzymes. The intra-melanosomal domain of human tyrosinase (residues 19-469) and two OCA1B related temperature-sensitive mutants, R422Q and R422W were expressed in insect cells and produced in T. ni larvae. The short trans-membrane fragment was deleted to avoid potential protein insolubility, while preserving all other functional features of the enzymes. Purified tyrosinase was obtained with a yield of >1 mg per 10 g of larval biomass. The protein was a monomeric glycoenzyme with maximum enzyme activity at 37°C and neutral pH. The two purified mutants when compared to the wild-type protein were less active and temperature sensitive. These differences are associated with conformational perturbations in secondary structure. The intramelanosomal domains of recombinant wild-type and mutant human tyrosinases are soluble monomeric glycoproteins with activities which mirror their in vivo function. This advance allows for the structure - function analyses of different mutant TYR proteins and correlation with their corresponding human phenotypes; it also provides an important tool to discover drugs that may improve tyrosinase activity and treat OCA1.

    Full Text Available BACKGROUND: Dengue illness causes 50-100 million infections worldwide and threatens 2.5 billion people in the tropical and subtropical regions. Little is known about the disease burden and economic impact of dengue in higher resourced countries or the cost-effectiveness of potential dengue vaccines in such settings. METHODS AND FINDINGS: We estimate the direct and indirect costs of dengue from hospitalized and ambulatory cases in Singapore. We consider inter alia the impacts of dengue on the economy using the human-capital and the friction cost methods. Disease burden was estimated using disability-adjusted life years (DALYs and the cost-effectiveness of a potential vaccine program was evaluated. The average economic impact of dengue illness in Singapore from 2000 to 2009 in constant 2010 US$ ranged between $0.85 billion and $1.15 billion, of which control costs constitute 42%-59%. Using empirically derived disability weights, we estimated an annual average disease burden of 9-14 DALYs per 100 000 habitants, making it comparable to diseases such as hepatitis B or syphilis. The proportion of symptomatic dengue cases detected by the national surveillance system was estimated to be low, and to decrease with age. Under population projections by the United Nations, the price per dose threshold for which vaccines stop being more cost-effective than the current vector control program ranged from $50 for mass vaccination requiring 3 doses and only conferring 10 years of immunity to $300 for vaccination requiring 2 doses and conferring lifetime immunity. The thresholds for these vaccine programs to not be cost-effective for Singapore were $100 and $500 per dose respectively. CONCLUSIONS: Dengue illness presents a serious economic and disease burden in Singapore. Dengue vaccines are expected to be cost-effective if reasonably low prices are adopted and will help to reduce the economic and disease burden of dengue in Singapore substantially.

    Few phenomena cause as much concern in developed countries as human exposure to artificial sources of radiation, and yet there are more potent threats to health: natural radiation is more pervasive and exposures more substantial; common practices such as smoking and drinking are more detrimental. Developing countries may be more anxious to establish radiological procedures than radiological protection. This paper gives the ranges of exposure to which people are subjected from natural and artificial sources which should help to put all doses in perspective. The relationship between dose and risk is established and used to show that exposures to radiation leak to low levels of risk. Finally, the new recommendations of ICRP for the control of radiation risk are presented. (Author)

    The children of mentally ill parents have a higher risk of developing mental illnesses themselves over the course of their lives. This known risk must be taken into account in the practical provision of health care. Selective literature review. The increased psychiatric risk for children of mentally ill parents is due partly to genetic influences and partly to an impairment of the parent-child interaction because of the parent's illness. Furthermore, adverse factors are more frequent in these families, as well as a higher risk for child abuse. Genetic and psychosocial factors interact with one another. For example, genetic factors moderate environmental effects; that is, the effect of adverse environmental factors depends on the genetic substrate. Preventive measures for children of mentally ill parents urgently need improvement. In this article, positively evaluated programs of preventive measures are discussed. Essential prerequisites for success include appropriate, specialized treatment of the parental illness, psychoeducative measures, and special support (e.g. self-help groups) as indicated by the family's particular needs.

    Although the prevalence of mental illness is similar across ethnic groups, a large disparity exists in the utilization of services. Mental health attributions, causal beliefs regarding the etiology of mental illness, may contribute to this disparity. To understand mental health attributions across diverse ethnic backgrounds, we conducted focus groups with African American (n = 8; 24 %), Asian American (n = 6; 18 %), Latino/Hispanic (n = 9; 26 %), and White (n = 11; 32 %) participants. We solicited attributions about 19 mental health disorders, each representing major sub-categories of the DSM-IV. Using a grounded theory approach, participant responses were categorized into 12 themes: Biological, Normalization, Personal Characteristic, Personal Choice, Just World, Spiritual, Family, Social Other, Environment, Trauma, Stress, and Diagnosis. Results indicate that ethnic minorities are more likely than Whites to mention spirituality and normalization causes. Understanding ethnic minority mental health attributions is critical to promote treatment-seeking behaviors and inform culturally responsive community-based mental health services.

METHODS: Using individual data from nationwide registers of patient with a diagnosis of bipolar disorder we calculated remaining life expectancies before age 90 years for values of age 15, 25, 35…75 years among all individuals alive in year 2000. Further, we estimated the reduction in life...... expectancy due to natural causes (physical illnesses) and unnatural causes (suicide and accidents) in relation to age. RESULTS: A total of 22,635 patients with bipolar disorder were included in the study in addition to data from the entire Danish general population of 5.4 million people. At age 15 years...

    To answer the questions of whether psychiatric patients should ever be allowed to refuse life-sustaining treatment in favor of comfort care for a condition that is caused by a psychiatric disorder, and if so, under what conditions. Case discussion and normative ethical and legal analysis. We argue that psychiatric patients should sometimes be allowed to refuse life-sustaining treatment in favor of comfort care for a condition that is caused by that psychiatric disorder and articulate the core considerations that should be taken into account when such a case arises. We also suggest that unwillingness among many, especially mental health professionals, to consider seriously both of these questions risks perpetuating stigmatization of persons with psychiatric disorders, i.e., that the "mentally" ill should not be allowed to make significant decisions for themselves-a-a stigmatization that can result in persons with mental disorders both being prevented from exercising autonomous choice even when they are capable of it, and being denied good comfort care at the end of life--care which would be offered to patients with similarly life-threatening conditions that were not deemed to be the result of "mental" illness.

    Holding positive beliefs about illness and having an optimistic outlook have been associated with increased well-being across a range of health conditions. However, research has indicated that being very optimistic may not actually be beneficial, and holding a realistic attitude is more adaptive in some forms of chronic illness, for example, Parkinson's disease (PD). This study aimed to explore the nature of relationships between illness perceptions, optimism and well-being: specifically, whether a linear or non-linear relationship best described the data. Additionally, the proposed moderating effect of optimism on the relationship between illness perceptions and well-being was tested. A total of 109 participants with idiopathic PD completed questionnaire measures of illness perception, optimism, mood and health-related quality of life (HRQoL). Multiple regression analyses were used to explore relationships between illness perceptions, optimism, mood and HRQoL. The potential curvilinear effects of illness perceptions and optimism were modelled using squared variables and linear and quadratic curve estimation. Holding positive illness perceptions predicted better well-being. Some evidence for a non-linear relationship between optimism and mood was found. Optimism had a significant moderating effect on the relationship between specific illness perceptions and outcome. Optimism appears to provide protection against some negative perceptions of illness and was associated with better mood and HRQoL. The findings indicate that specific illness perceptions may be beneficial targets for therapy. Therapeutic interventions should focus on enhancing positive perceptions of PD but potentially more importantly general optimistic attitude to maximize well-being. What is already known on this subject? Positive illness perceptions and high optimism are associated with better well-being in a range of conditions, both chronic and acute. Preliminary studies suggest that in chronic
