Full Text Available Zoonoses are discussed as occupational diseases, with special reference to animal husbandry and related activities. After quoting some historical references, occupational zoonoses are examined in relation to the evolution of the concept of occupational zoonosis, the involvement of the World Health Organization in this field, their socio-economic significance, the principal working activities, zoonoses of greatest importance (with special reference to the Mediterranean region, the evaluation of damage and risks. An outline is made of the transmission of zoonoses from farm workers to animals and the biological hazards from the environment. The present situation of occupational zoonoses and related risks in industrialised and traditional farming activities are presented and the importance of some emerging and re-emerging zoonoses for the health of workers is highlighted. The author concludes by stressing that the prevention of occupational zoonoses must be implemented jointly by both veterinary and medical services through preventive measures and epidemiological surveillance of human and animal health, risk evaluation, diagnosis of infections and prompt reporting. It is hoped that the future will offer better inter-disciplinary collaboration and that legislation will be timely and better tailored to safeguard working health and safety.

Background Understanding the drivers of habitat selection by insect disease vectors is instrumental to the design and operation of rational control-surveillance systems. One pervasive yet often overlooked drawback of vector studies is that detection failures result in some sites being misclassified as uninfested; naïve infestation indices are therefore biased, and this can confound our view of vector habitat preferences. Here, we present an initial attempt at applying methods that explicitly account for imperfect detection to investigate the ecology of Chagas disease vectors in man-made environments. Methodology We combined triplicate-sampling of individual ecotopes (n = 203) and site-occupancy models (SOMs) to test a suite of pre-specified hypotheses about habitat selection by Triatoma brasiliensis. SOM results were compared with those of standard generalized linear models (GLMs) that assume perfect detection even with single bug-searches. Principal Findings Triatoma brasiliensis was strongly associated with key hosts (native rodents, goats/sheep and, to a lesser extent, fowl) in peridomestic environments; ecotope structure had, in comparison, small to negligible effects, although wooden ecotopes were slightly preferred. We found evidence of dwelling-level aggregation of infestation foci; when there was one such focus, same-dwelling ecotopes, whether houses or peridomestic structures, were more likely to become infested too. GLMs yielded negatively-biased covariate effect estimates and standard errors; both were, on average, about four times smaller than those derived from SOMs. Conclusions/Significance Our results confirm substantial population-level ecological heterogeneity in T. brasiliensis. They also suggest that, at least in some sites, control of this species may benefit from peridomestic rodent control and changes in goat/sheep husbandry practices. Finally, our comparative analyses highlight the importance of accounting for the various sources of

Terrestrial carnivores typically have large home ranges and exist at low population densities, thus presenting challenges to wildlife researchers. We employed multiple, noninvasive survey methods—scat detection dogs, remote cameras, and hair snares—to collect detection–nondetection data for elusive American black bears (Ursus americanus), fishers (Martes pennanti), and bobcats (Lynx rufus) throughout the rugged Vermont landscape. We analyzed these data using occupancy modeling that explicitly incorporated detectability as well as habitat and landscape variables. For black bears, percentage of forested land within 5 km of survey sites was an important positive predictor of occupancy, and percentage of human developed land within 5 km was a negative predictor. Although the relationship was less clear for bobcats, occupancy appeared positively related to the percentage of both mixed forest and forested wetland habitat within 1 km of survey sites. The relationship between specific covariates and fisher occupancy was unclear, with no specific habitat or landscape variables directly related to occupancy. For all species, we used model averaging to predict occurrence across the study area. Receiver operating characteristic (ROC) analyses of our black bear and fisher models suggested that occupancy modeling efforts with data from noninvasive surveys could be useful for carnivore conservation and management, as they provide insights into habitat use at the regional and landscape scale without requiring capture or direct observation of study species.
Full Text Available Background: The aim of the paper was to present basic statistical data on occupational diseases diagnosed in 2012. Material and Methods: The work was based on the data from "Occupational Disease Reporting Forms" received by the Central Register of Occupational Diseases in 2012. The data comprised information on nosologic units, gender and age of patients, duration of occupational exposure, sections of the national economy and voivodeships. The incidence was specified in terms of the number of cases in relation to paid employees or to employed people. Results: The number of occupational diseases accounted for 2402 cases. The incidence rate was 23 cases per 100 000 paid employees. In spite of the general decline in the number of cases, the incidence of infectious and parasitic diseases increased by 8.6%. The highest incidence was noted for infectious and parasitic diseases (6.8/100 000, pneumoconioses (5.5/100 000, hearing loss (2.1/100 000, diseases of: the peripheral nervous system (2/100 000, voice disorders (1.9/100 000 and the musculo-skeletal system pathologies (1.1/100 000. The pathologies specified above accounted in total for 84% of all occupational diseases. The industrial sectors of the national economy characterized by the highest incidence included mining and quarrying (288.3/100 000 and manufacturing (27.8/100 000. The highest incidence was recorded in the Silesian (46.2/100 000 and the lowest in the Opolskie (4.2/100 000 voivodeships. Conclusions: The downward trend in the incidence of occupational diseases continues. Different incidence of voice disorders among teachers in individual provinces suggests that uniform preventive, diagnostic and certification standards are missing. Med Pr 2013;64(3:317–326
Full Text Available Occupational neurotoxic diseases have become increasingly common in Taiwan due to industrialization. Over the past 40 years, Taiwan has transformed from an agricultural society to an industrial society. The most common neurotoxic diseases also changed from organophosphate poisoning to heavy metal intoxication, and then to organic solvent and semiconductor agent poisoning. The nervous system is particularly vulnerable to toxic agents because of its high metabolic rate. Neurological manifestations may be transient or permanent, and may range from cognitive dysfunction, cerebellar ataxia, Parkinsonism, sensorimotor neuropathy and autonomic dysfunction to neuromuscular junction disorders. This study attempts to provide a review of the major outbreaks of occupational neurotoxins from 1968 to 2012. A total of 16 occupational neurotoxins, including organophosphates, toxic gases, heavy metals, organic solvents, and other toxic chemicals, were reviewed. Peer-reviewed articles related to the electrophysiology, neuroimaging, treatment and long-term follow up of these neurotoxic diseases were also obtained. The heavy metals involved consisted of lead, manganese, organic tin, mercury, arsenic, and thallium. The organic solvents included n-hexane, toluene, mixed solvents and carbon disulfide. Toxic gases such as carbon monoxide, and hydrogen sulfide were also included, along with toxic chemicals including polychlorinated biphenyls, tetramethylammonium hydroxide, organophosphates, and dimethylamine borane. In addition we attempted to correlate these events to the timeline of industrial development in Taiwan. By researching this topic, the hope is that it may help other developing countries to improve industrial hygiene and promote occupational safety and health care during the process of industrialization.

Scabies is an infectious skin disease caused by the human itch mite (Sarcoptes scabiei var. hominis). It is mainly transmitted by direct skin-to-skin contact. The spread of scabies can cause major difficulties in healthcare institutions, particularly in residential homes for the elderly. The disease is characterized by intense nocturnal itching, erythematous papules arranged in a linear order, and scratching resulting in excoriations. The diagnosis is confirmed by identification of the mite or by finding one or more mite tunnels in the skin. An individually occurring case does not need to be reported. If two or more cases occur in the same institution, the company physician and the appropriate public health department are to be informed in Germany. In case of a suspected scabies infection in medical personnel due to exposure in their work setting, medical notification to the statutory occupational accidents' insurance (Nr. 3101) is to be issued in accordance with § 202, Volume VII of the German Social Code. First line treatment is topical therapy with 5 % permethrin. If scabies control is required in an institution, systemic treatment with ivermectin may be considered. In the case of a scabies outbreak, all patients, contact persons, and staff must be treated simultaneously.

Lung cancer is one of the most frequently encountered cancer types. According to the latest WHO data, about 10 % of this disease are due to occupational exposure to cancerogens. Asbestos is still the number one carcinogen. Further frequent causes include quarz and ionizing radiation (uranium mining). Probable causes of the disease can be identified only with the help of detailed occupational history taken by a medical specialist and qualified exposure assessment. Without clarifying the cause of the disease, there is neither a correct insurance procedure nor compensation for the victim, and furthermore, required preventive measures cannot be initiated. © Georg Thieme Verlag KG Stuttgart · New York.

The concept of 'one airway, one disease' refers to the frequent comorbidity of asthma and rhinitis. However, only limited research has been done on this association for the diverse range of occupational respiratory sensitisers. The relative frequency of rhinitis was determined for the 15 respiratory sensitisers reported to cause at least 10 cases of rhinitis or asthma to The Health and Occupation Reporting (THOR) network between 1997 and 2006. Of 1408 cases, 1190 were sole diagnoses of asthma, 138 sole diagnoses of rhinitis and in 80 cases asthma coexisted with rhinitis. The six sensitisers for which rhinitis featured in over 15% of cases were all particulates and known to cause release of mast cell mediators, either directly or through IgE antibodies. Four of the other nine sensitisers often exist as vapours and only two have been consistently associated with IgE-mediated disease mechanisms. Particle size did not appear to correlate with the relative frequency of rhinitis. Despite its limitations this study would support the hypothesis that there are at least two mechanistic categories of respiratory sensitisation with rhinitis being relatively more common where the mechanism is IgE-mediated. Particulate nature may be another important factor to consider in future studies.

Air dustiness and mineralogical composition of dust in 9 building ceramics plants producing red brick were tested. Also analysed were occupational diseases diagnosed in Poland during 1979-1980 in workers of this industry. Concentrations of total dust and respirable fraction at all workstations exceeded the present mandatory allowable values for dusts containing free crystalline silica. By X-ray diffraction, alpha-quartz and illite were found in raw materials (clays) and intermediate products (green brick). In burnt brick alpha-quartz and mullite were found. The content of free crystalline silica was: in clay--over 30%, in total dust--5.8-18.4%, in respirable fraction 3.7-6.1%. Analysis of occupational diseases diagnosed in Poland during 1979-1980 revealed not a single case of pneumoconiosis or any dust--induced respiratory tract disease in those producing red brick. Instead, two pneumoconiosis cases were found among workers of the plant producing thermallite firebrick of biologically aggressive siliceous earth from Piotrowice--as one of its component. Most frequently, workers of the building ceramics plant were afflicted with occupational dermatoses, mostly this relates to bricklayers exposed to cement mortar. Two cases of occupational dermatosis were those of workers exposed to ash.

To describe the characteristics of patients with occupational skin disease (OSD) in a tertiary referral clinic in Victoria, Australia. A retrospective review was conducted of records from patients seen at the Occupational Dermatology Clinic in Melbourne, Australia between 1 January 1993 and 31 December 2010. Of the 2894 people assessed in the clinic during the 18-year period, 44% were women and 56% were men. In all, 2177 (75%) were diagnosed with occupational skin disease (OSD). Of the patients with a work-related skin condition, 45% (n = 979) were considered to be atopic. The most common diagnosis in those with OSD was irritant contact dermatitis (ICD) (44%), followed by allergic contact dermatitis (33%) and endogenous eczema (11%). Women were significantly more likely to have soaps and detergents (P care workers (21 per 100 000). We confirm the importance of occupational contact dermatitis as the most common cause of OSD, with ICD being the most common diagnosis. There are differences in the causes of ICD between our group of male and female workers. For the first time in Australia, rates of OSD in certain industries have been calculated. © 2015 The Australasian College of Dermatologists.

Studies on occupational skin diseases in workers of the automotive industry are few. To investigate the prevalence of occupational skin diseases in workers of the automotive industry. Between September and December 2011, a total of 405 workers from the automotive repair industry in Diyarbakır were interviewed. They were active workers in the repair industry who had been employed for at least six months. Business owners, sellers of spare parts and accounting officers were not included. The employees were examined at their workplaces and the working conditions were observed. Detailed dermatological examination was performed. The mean age of the 405 workers who participated in the study was 27.7 ± 10.3. The mean working time of employees was 13.3 ± 10.4 years. All of the employees were male. Dermatological diseases were not detected in 144 out of 405 workers (35.6%) and at least one condition was diagnosed in 261 (64.4%). The most frequent diagnosis was callus, hyperkeratosis, clavus (27.7%), followed by nail changes (16.8%) and superficial mycoses (12.1%). Contact dermatitis was seen at a rate of 5.9%. Traumatic lesions such as hyperkeratotic lesions and nail changes were found most frequently. Traumatic lesions were common among individuals who did not use gloves. Most nail changes were localized leuconychia, a finding not reported in the studies on automotive industry workers. In accordance with the literature, irritant contact dermatitis was observed in patients with a history of atopy and who had been working for a long time. Occupational skin diseases comprise an important field in dermatology, deserving much attention. Further studies on occupational dermatology are necessary.

Occupational immunologic lung disease is characterized by an immunologic response in the lung to an airborne agent inhaled in the work environment and can be subdivided into immunologically mediated occupational asthma (OA) and hypersensitivity pneumonitis (HP). Irritant-induced OA, a separate nonimmunologic entity, can be caused by chronic exposure to inhaled irritants or reactive airways dysfunction syndrome, defined as an asthma-like syndrome that persists for >3 months and occurs abruptly after a single exposure to a high concentration of an irritating industrial agent. High-risk fields for OA include farmers, printers, woodworkers, painters, plastic workers, cleaners, spray painters, electrical workers, and health care workers. OA can be triggered by high molecular weight (HMW) proteins that act as complete allergens or low molecular weight (LMW) sensitizers that act as haptens. HMW proteins (>10 kDa) are generally derived from microorganisms (such as molds and bacteria, including thermophilic actinomycetes), plants (such as latex antigens and flour proteins), or animals (such as animal dander, avian proteins, and insect scales) and are not specifically regulated by the Occupational Safety and Health Administration (OSHA). LMW haptens that bind to proteins in the respiratory mucosa include some OSHA-regulated substances such as isocyanates, anhydrides, and platinum. HP can present in an acute, a chronic, or a subacute form. The acute, subacute, and early chronic form is characterized by a CD4(+) T(H)1 and CD8(+) lymphocyte alveolitis. Classically, the bronchoalveolar lavage will show a CD4/CD8 ratio of <1.

Social media have great impact on all aspects of life throughout the world. The utilization of social media for occupational lung disease, however, has been much more limited. This article summarizes recent literature concerning social media for occupational lung disease and identifies areas for additional use. Social media are used in six relevant areas: information dissemination, peer-to-peer communication, survey research data collection, participatory research and exposome data acquisition, assessing public concerns, and knowledge generation. There are very clear advantages for information dissemination from experts to workers and on a peer-to-peer basis, although variable credibility and accuracy concerns persist. For research, social media have been used for acquiring data posted for nonresearch purposes and for efficiently collecting information specifically for research. The benefits of efficiency, democracy, and very large data sources may counterbalance concerns about inadequate specification of recruitment strategies and limited control over data quality. The potential benefits of using social media for lung health-workplace interactions are much greater than the very limited current utilization.

The study investigates the course of the disease of persons whose occupational exposure to radiation had resulted in impairment of their professional ability and entitled them to damages under the current regulations. 35 receivers of damages were found who by answering the question form and partly giving permission to study their file at the insurance institution under the conditions of data protection made is possible to carry through this investigation. 14 receivers of damages were occupied in the technical industry, 21 in the sector of medicine. The radiation disease acknowledged as professional concerned in 30 cases the skin, in two cases the lungs and in one case each the haematopoietic system, the eyes and the pelvic organs. In 8 indemnified, acute radiation exposure had caused the disease, in 25 the time of exposure had ranged from one year to several decades. The investigation describes when and under what professional circumstances the radiation exposure took place, the course of the disease, what kind of diagnostic and therapeutical measures were carried through and what personal and professional consequences the indemnified sustained. It gives suggestions to set up a future, more effective documentation system on the basis of the experience gathered on the occasion of this investigation with the currently valid registration system, which is unsuitable for further scientific studies, and with the currently practised methods of after-care.

Streptococcus suis is a zoonotic pathogen with worldwide distribution, responsible for more than 700 human cases globally reported. This infection affects mostly men, exposed to pig or pork, which leads to its usual classification as an occupational disease. We report a case of acute bacterial meningitis in a 44 years old male. According to his past medical history, the patient had chronic alcoholism and worked in a restaurant as a piglet roaster. Microbiological examination of blood and CSF revealed S. suis. After 14 days of ceftriaxone the patient fully recovered. The authors review the clinical reports previously described in Portugal. In all of them was possible to identify risk exposition to pork. We alert to this microorganism's importance in Portugal where it is probably underdiagnosed.

To investigate possible associations between cardiovascular malformations and maternal occupational exposure to various factors during the first trimester of pregnancy, 406 cases and 756 controls were studied retrospectively. The cases were taken from all infants diagnosed with cardiovascular malformations born in Finland during 1982 and 1983. The controls were randomly selected from all normal births in the country during the same period. All mothers were interviewed approximately 3 months after delivery by a midwife, using a structured questionnaire. Maternal overall exposure to chemicals at work was more prevalent among the case group (35.8%) than the control group (26.2%, P less than 0.01). Among the specific chemical groups, maternal exposure to dyes, lacquers, or paints was significantly associated with the risk of congenital heart disease. Exposure to organic solvents during the first trimester seemed to increase to risk of ventricular septal defect (P less than 0.05). Work at video display terminals was slightly more prevalent among the case group (6.3%) than among the control group (5.0%). The mothers' education level, regular exposure to passive smoking at work, or temperature at the workplace were not risk factors for congenital heart disease in the offspring, neither was maternal exposure to microwave ovens, disinfectants, pesticides, or anesthetic gases. It is concluded that many maternal exposures at work seem not to have a teratogenic effect on the fetal heart, although the limited power of this investigation needs to be borne in mind.

The incidence of occupational diseases (ODs) is below expectations. The approaches of family physicians are very important. In this study, we aimed to evaluate attitudes and behaviors of family physicians about ODs. The questionnaire was first sent to family physicians via e-mail. Of 3663 responders, 3090 replies were included to study. 44.1% of them stated they obtained detailed occupational history. In logistic regression analysis, physicians who obtained detailed occupational history, discussed their patient's health with an occupational physician, had education about ODs and those who stated that they wanted to receive training in ODs were more likely to refer their patient. In this study, it was determined that those who received education on ODs and those who have worked as workplace physician obtained occupational history, knew occupational diseases hospitals and wanted to receive further education.

Though scientifically undisputed, cutaneous syncarcinogenesis is not reflected in German occupational disease (OD) regulations, which tend to be guided by the tenet of monocausality. Recognition of nonmelanoma skin cancer (NMSC) and its precursor lesions as OD requires individual assessment as to whether the requirements pursuant to either OD 5103 (occupational exposure to natural UV radiation) or OD 5102 (occupational exposure to polycyclic aromatic hydrocarbons) are fulfilled. Retrospective analysis of 28 patients (median age 72.5 years) with NMSC and respective precursor lesions who had been occupationally exposed to natural UV radiation and polycyclic aromatic hydrocarbons. All cases had undergone expert medical assessment between September 2012 and September 2015. According to our assessments, all 28 cases met the occupational requirements pursuant to OD 5103 and 5102. In 26 cases (93 %), we recommended recognition of skin cancer as occupational disease pursuant to both OD 5103 and OD 5102. The competent occupational insurance association (BG) followed our recommendation in four cases. In eight cases, recognition was solely based on OD 5103; in ten cases, only on OD 5102. Four cases were denied recognition. Following adequate cumulative occupational exposure to natural UV light as well as occupational exposure to polycyclic aromatic hydrocarbons, NMSC or its precursor lesions arising in UV-exposed areas should be reported to the competent occupational insurance association as "OD 5103 and 5102 in terms of syncarcinogenesis". Apart from the fact that the ensuing recognition proceedings will be able to more adequately reflect real-life workplace conditions, filing a report pursuant to both ODs also allows for recognition of basal cell carcinoma as occupational disease. According to current regulations, this would not be possible, if the assessment were solely based on OD 5103. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons

Evidence Connection articles provide a clinical application of systematic reviews developed in conjunction with the American Occupational Therapy Association's (AOTA's) Evidence-Based Practice Project. In this Evidence Connection article, we describe a case report of a person with Alzheimer's disease. The occupational therapy assessment and intervention process in the home setting is described. Findings from the systematic reviews on this topic were published in the November/December 2017 issue of the American Journal of Occupational Therapy and in AOTA's Occupational Therapy Practice Guidelines for Adults With Alzheimer's Disease and Related Major Neurocognitive Disorders. Each article in this series summarizes the evidence from the published reviews on a given topic and presents an application of the evidence to a related clinical case. Evidence Connection articles illustrate how the research evidence from the reviews can be used to inform and guide clinical reasoning.

Shoe manufacturing workers are exposed daily to an extensive range of potential physical and chemical occupational hazards. Shoe manufacturing in Indonesia is one of the industrial sectors that has shown sustained growth amongst the newly industrialized countries (NICs). In this study, we investigated the possible potential exposure of the workers to physical and occupational hazards and determined the prevalence of occupational skin diseases at a shoe manufacturing factory in Indonesia. A cross-sectional study on the observation of the working process and an inventory and risk assessment of exposure to the chemicals used. Classification of chemicals as potential sensitizers/irritants and qualitative assessments of these chemicals were done. Workers were examined and interviewed using the Nordic Occupational Skin Questionnaire-2002/LONG. The risk of Occupational skin diseases (OSD) at the shoe factory was mainly related to the exposure of the workers' skin to potential physical and chemical hazards in hot and humid environmental conditions. From a total of 514 workers, 8.5 % reported current OSD and 4.8 % reported a history of OSD. Occupational skin diseases were diagnosed in 29 % of the workers by dermatologists and 7.6 % had an occupational contact dermatitis (OCD). Of the 39 workers with contact dermatitis, 33 consented to being patch tested, 14 (3 %) workers showed a positive results and considered as having an occupational allergic contact dermatitis (OACD) and 25 (4.9 %) had an occupational irritant contact dermatitis (OICD). We observed a repeated and prolonged exposure of the workers to numerous physical and chemical skin hazards at this factory.
Full Text Available Objectives: The automotive industry represents the most important industrial sector in Czechia. The objective of this study has been to analyze the occurrence of occupational diseases (OD in the automotive industry during the period from 2001 till 2014. Material and Methods: Data on OD cases was retrieved from the National Registry of OD. Further, we conducted a survey in automotive companies with focus on occupational health services and positions of the companies in global production networks (GPNs. An analysis of OD distribution in the automotive industry was performed (age, gender, company size and its role in GPNs, regional distribution of studied companies, and regional unemployment rate, and was accompanied by assessment of the quality and range of occupational health services. Results: Employees older than 40 years old have nearly 2.5 times higher probability of OD occurrence as compared with employees younger than 40 years old (odds ratio (OR = 2.41, 95% confidence interval (CI: 2.05–2.85. Occupational diseases occurrence probability was 3 times higher for women than for men (OR = 3.01, 95% CI: 2.55–3.55. Occupational diseases incidence rates increased with the size of the company (0 OD/10 000 employees in micro enterprises to 57 OD/10 000 employees in large enterprises. A particularly steep rise in OD incidents in the automotive industry was observed in the Plzeň Region between 2001 and 2011. An association between OD incidents and the unemployment rate was not statistically confirmed. Conclusions: A statistically significant increase in OD incidents dependent on company size may be arguably attributed to a higher quality of occupational medical services in bigger companies, which ensures better detection and diagnosis of OD. In the Plzeň Region, the rapid increase in OD incidents was mainly caused by a change in the production process of automobile textiles in one factory due to the introduction of a glue containing isocyanates

regular monitoring and periodic publication of the quality of water, air and soil; preventing deforestation and man-made soil erosion, increasing forest and ground cover, preventing occupational injuries, judicious and safe use of agrochemicals, sustainable agriculture and development programs, and implementing legislation to protect and conserve water heriage and the environment. These actions are essential both for a healthier environment and for the health of the people who live in that environment. Such measures would also decrease public health threats from such, including global-warming-related erratic environmental changes and the occurrence and the spread of non-communicable diseases, such as CKDmfo.

In recent years a great number of studies suggests that occupational exposures could play a role in the onset of some neurodegenerative diseases. The literature data are more numerous for Parkinson's disease, Multiple Sclerosis and Amyotrophic Lateral Sclerosis, although to date no specific occupational exposure was proved to be a definite causal factor. This lack of information is attributable both to the complex patogenesis of these diseases and to a delay regarding this field of research with respect to others pathologies. Nevertheless, available evidence oblige researchers to deepen the studies of occupational exposures as risk factors of neurodegenerative diseases, in order to provide a solid basis possible preventive measures for a class of pathologies with high social impact, both in terms of therapies and in terms of disability.

. One of the major goals of the institutions for statutory accident insurance is the prevention of occupational diseases. To perform a successful prevention work it is necessary not only to count the number of accidents or diseases in the various working fields but to look for details of the conditions of work and the human response to those conditions. The institutions for statutory accident insurance have engaged the institution for statutory accident insurance in the precision engineering and electrical industry to carry out documentation, in form of a data bank, for all cases of occupational diseases which could be caused by ionising radiation. Those are not only the cases which are accepted as occupational disease but also the cases where a suspicion of an occupational disease is announced but finally rejected. At the moment about 1700 cases are included in the data bank. For preserving the anonymity information to name and residence are deleted. Various data to one single case are linked by a case-specific key-number. Information to occupation and field of working, to details of a possible exposure to ionising radiation like kind of radiation, time and duration of radiation, exposure of the whole body or of parts of the body and whole body or organ doses are collected. Additional information refers to medical aspects like diagnosis and date of diagnosis. (Author)
Full Text Available Background: On 3 July 2009, new law pertaining to occupational diseases (ODs became effective in Poland. The article presents opinions of the representatives of the 1st degree ODs certification entities and sanitary inspectorates on the changes in OD law and the problems that may cause difficulties and/or certification errors. Material and Methods: A questionnaire study was performed covering representatives of 20 voivodeship occupational medicine centers and 40 national district sanitary inspectorates. We received 57 completed questionnaires which were analyzed. Results: Positive opinions were expressed on changes in procedures on reporting suspected occupational diseases (50%, keeping time limits for diagnosing ODs (89.2%, and changes pertaining to entities responsible for certifying infectious ODs (92.9%. A large group of respondents (66.7% was in favor of conducting jointly an occupational exposure risk analysis by occupational medicine physicians and occupational health and safety practitioners and/or sanitary inspectors. One-third of the respondents declared that changes in the list of ODs had no influence on the certification procedure. Conclusions: New law has improved the existing procedure of ODs certification. There is a need to elaborate detailed diagnostic guidelines on and criteria for ODs identification and recognition. A panel of experts should be established by the Ministry of Health to track the latest advancements in medicine and to update the list of ODs. Conducting jointly an occupational exposure risk analysis by occupational medicine physicians and occupational health and safety practitioners and/or sanitary inspectors should become a standard.

Little research has been focused on the health status or the occupational protection awareness of sanitation workers. The policy recommendations on the occupational safety and health of sanitation workers based on the scientific research are also insufficient in developing countries like China. To study the incidence of dermatoses and the relevance with occupational exposure, protection awareness and protective measures among sanitation workers for better management and protection of the sanitation workers. 273 sanitation workers and 113 administrative staff from 11 streets of Wuhan were recruited. Dermatological problems were evaluated and recorded by physical examination. Occupational exposure, protection awareness, the use of protective equipments and personal history of skin disease were assessed by questionnaires. Compared with administrative staff, sanitation workers had much more occupational dermatological problems and had a much higher rate of harmful ultraviolet ray exposure. Young sanitation workers were more aware of occupational self-protection and a relatively higher rate of them using protective equipments compared with old ones. Exposure to multiple health hazards and the poor use of protective equipments are related to skin diseases in sanitation workers. Prejob training of self-protection and the use of protective equipments are recommended.
Full Text Available Voice disorders are all changes in the voice quality that can be detected by hearing. Some etiological factors that contribute to the development of voice disorders are related to occupation, working environment and working conditions. In modern societies one third of the labour force works in professions with vocal loading. In such professions, voice disorders influence work ability and quality of life. For an occupational disease, the exposure to harmful factors in the workplace is essential and causes the development of a disorder in a previously healthy individual. In some European countries, voice disorders in teachers, which do not improve after proper treatment are recognized as occupational diseases. In Slovenia, no organic or functional voice disorder is listed on the current list of occupational diseases. Prevention and cure of occupational voice disorders can contribute to better safety at the workplace and improve the workers’ health. Voice professionals must also know that they are responsible for their own health and that they must actively take care of it.

Background Official statistics tend to underestimate the incidence of occupational disease (OD) nationally and regionally in Russia. Objectives The general aim was to obtain an accurate estimate of ODs in Murmansk Oblast in 1980–2010 and to determine the rate of specific types of ODs among cohorts of workers who had been exposed to the hazardous factors causing the disease. Materials and methods Data were retrieved from the Murmansk Oblast ODs database for the oblast and 2 enterprises – Apatite JSC and Kolskaya MSC – which contributed to more than half of the ODs in the oblast in 1980–2010. The total number of ODs and 5 specific categories (musculoskeletal, respiratory, nervous diseases, hearing loss and vibration disease) were analysed. Results The total rate of ODs among workers of main shops in both enterprises who were actually exposed to harmful factors were extremely high: the rate for Apatite JSC was 25 times higher than in Russia and 15 times higher than in Murmansk Oblast, while the rate for Kolskaya MSC was about 30 and 20 times greater than in Russia and in Murmansk Oblast, respectively; in the 2000s the difference reached 100–150 times. The rise in reported ODs in both enterprises corresponded to the time when intensive medical examinations were conducted by the Kola Research Laboratory for Occupational Health (KRLOH) in Kirovsk. A similar pattern was also observed for the sub-categories of musculoskeletal, respiratory, nervous diseases, hearing loss and vibration disease. It is likely that the true burden of OD is even higher due to misdiagnosis, reluctance of workers concerned about job security to present for care and the lack of reliable information on working conditions needed to establish a causal link between disease and occupational exposure. Conclusions As with many other regions across Russia, ODs in Murmansk Oblast are grossly underestimated. Serious problems exist in the Russian occupational health care system and the collection of

Under-reporting of occupational diseases is an important issue worldwide. The collection of reliable data is essential for public health officials to plan intervention programmes to prevent occupational diseases. Little is known about the effects of interventions for increasing the reporting of occupational diseases. To evaluate the effects of interventions aimed at increasing the reporting of occupational diseases by physicians. We searched the Cochrane Occupational Safety and Health Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (PubMed), EMBASE, OSH UPDATE, Database of Abstracts of Reviews of Effects (DARE), OpenSIGLE, and Health Evidence until January 2015.We also checked reference lists of relevant articles and contacted study authors to identify additional published, unpublished, and ongoing studies. We included randomised controlled trials (RCTs), cluster-RCTs (cRCTs), controlled before-after (CBA) studies, and interrupted time series (ITS) of the effects of increasing the reporting of occupational diseases by physicians. The primary outcome was the reporting of occupational diseases measured as the number of physicians reporting or as the rate of reporting occupational diseases. Pairs of authors independently assessed study eligibility and risk of bias and extracted data. We expressed intervention effects as risk ratios or rate ratios. We combined the results of similar studies in a meta-analysis. We assessed the overall quality of evidence for each combination of intervention and outcome using the GRADE approach. We included seven RCTs and five CBA studies. Six studies evaluated the effectiveness of educational materials alone, one study evaluated educational meetings, four studies evaluated a combination of the two, and one study evaluated a multifaceted educational campaign for increasing the reporting of occupational diseases by physicians. We judged all the included studies to have a high risk of bias
Full Text Available During a three–year period (2001-2003, occurrence of diseases on sunflower stems was monitored in fields of PIK Vinkovci (on the Sopot location. The experiment involved 24 genotypes planted in 2001, 30 genotypes in 2002, and 20 genotypes in 2003, each of them repeated in two trials: treated and non-treated. The Konker fungicide preparation, dosed 1.5 l/ha, was used for sunflower protection. The treatment was applied at the R1-R2 development stage of sunflower (the size of immature bud was up to 2 cm. Based on the conducted survey, it was found out that Sclerotinia sclerotiorum was the most dominant disease agent to sunflower stems in 2001. Percentage of infection for the non-treated and treated trials was between 0 and 32.5%, and 0 and 17.5%, respectively. In 2002 and 2003, Phomopsis helianthi was the most dominant disease agent. Average value rate in 2002 fluctuated between 0.65 and 4.00 in non-treated trial and between 0.05 and 2.60 in treated trial. In 2003, occurrence of P. helianthi was of weak intensity, mostly because of unfavorable weather conditions for parasite development. Average ratings were 0.35 to 3.30 in the non-treated trial, and 0.20 to 1.85 in the treated trial. Application of fungicide during the whole experiment period had positive effects on the decrease of infection intensity and the increase of grain and oil yields.

Objectives This study aimed to examine whether occupational and physical activity (PA) at different ages contribute to Parkinson's disease (PD) risk in a large population-based case-control study in Denmark. Methods We identified 1828 PD patients from the Danish National Hospital Register and recruited 1909 gender and year of birth matched controls from the Danish Central Population Register. Occupational and leisure-time PA were determined from a job exposure matrix based on occupational history and self-reported leisure-time information. Results No association was found for occupational PA alone in men, but higher leisure-time PA (≥5 hours/week of strenuous activities) in young adulthood (15-25 years) was associated with a lower PD risk (adjusted odds ratio (OR adj ) 0.75, 95% confidence interval (95% CI) 0.62-0.90); men who engaged in high occupational and high leisure-time PA in young adulthood had the lowest PD risk (OR adj 0.58, 95% CI 0.41-0.81). Among women, inverse associations were found for occupation PA before age 50 (highest vs lowest, OR adj 0.75, 95% CI 0.55-1.06) and strenuous leisure-time PA after age 50 (OR adj 0.65, 95% CI 0.87-0.99); no clear pattern was seen for leisure and occupational PA combined. Conclusions We observed gender-specific inverse associations between occupational and leisure-time PA and PD risk; however, we cannot preclude reverse causation especially in older ages since PD has a long prodromal stage that might lead to a reduction of PA years before motor symptom onset and PD diagnosis.

The objective of this review is to highlight the impact of insomnia in central neurological disorders by providing information on its prevalence and give recommendations for diagnosis and treatment. Insomnia in neurological disorders is a frequent, but underestimated symptom. Its occurrence may be a direct consequence of the disease itself or may be secondary to pain, depression, other sleep disorders or the effects of medications. Insomnia can have a significant impact on the patient's cognitive and physical function and may be associated with psychological distress and depression. Diagnosis of insomnia is primarily based on medical history and validated questionnaires. Actigraphy is a helpful diagnostic tool for assessing the circadian sleep-wake rhythm. For differential diagnosis and to measure the duration of sleep full polysomnography may be recommended. Prior to initiating treatment the cause of insomnia must be clearly identified. First line treatment aims at the underlying neurologic disease. The few high quality treatment studies show that short term treatment with hypnotics may be recommended in most disorders after having ruled out high risk for adverse effects. Sedating antidepressants may be an effective treatment for insomnia in stroke and Parkinson's disease (PD) patients. Melatonin and light treatment can stabilize the sleep-wake circadian rhythm and shorten sleep latency in dementias and PD. Cognitive behavioral therapy (CBT) can be effective in treating insomnia symptoms associated with most of the central neurological diseases. The prevalence and treatment of insomnia in neurological diseases still need to be studied in larger patient groups with randomized clinical trials to a) better understand their impact and causal relationship and b) to develop and improve specific evidence-based treatment strategies.

Occupational contact dermatitis (OCD) is a common occupational disease. Evidence suggests that education and training are effective prevention strategies. In spite of these known prevention strategies, workers continue to develop OCD. Little is reported regarding the actual training experience of workers. To examine the training experience of workers with contact dermatitis to identify areas for improvement. Participants were workers being assessed for contact dermatitis in an occupational health clinic. The anonymous survey collected demographics, workplace characteristics, and education and prevention practices. Approximately 80% reported general occupational health and safety training; however, only 49% reported skin-specific training (SST). For workers reporting SST, most received information regarding exposure avoidance, hand washing, and glove use. This content was reported as helpful by at least 50%. Workers who did not receive SST indicated the most important content would be warning signs of skin problems, how to avoid exposure and skin care while using gloves. While the study was anonymous and used self-reported of training experience, the study suggests there are gaps in skin protection training. Addressing these gaps may lead to improved prevention and reduction in OCD. © The Author(s) 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

Chronic skin diseases, particularly psoriasis and atopic dermatitis, have a negative impact on patients' quality of life. Patients often experience significant psychological and social distress such as increased levels of depression and fear of stigma. Skin diseases can also impact patients' occupational lives by causing them to miss work or be less productive. Quality of life instruments provide important information for healthcare professionals, the general public, and those involved in distribution of healthcare resources, which helps prevent chronic skin disease from being overlooked amidst other medical conditions.

Occupational contact dermatitis (OCD) is a common occupational disease that impacts a variety of worker groups. Skin protection and disease prevention training programs have shown promise for improving prevention practices and reducing the incidence of OCD. This review details the features of training programs for primary prevention of OCD and identifies gaps in the literature. Twelve studies were identified for in-depth review: many studies included wet workers employed in health care, hairdressing, cleaning, and food preparation; 1 program featured manufacturing workers. Few programs provided content on allergic contact dermatitis, and only 1 was evaluated for long-term effectiveness. Effective programs were similar in content, delivery method, and timing and were characterized by industry specificity, multimodal learning, participatory elements, skin care resource provision, repeated sessions, and management engagement. Long-term effectiveness, generalizability beyond OCD, workplace health and safety culture impact, and translation of programs in the North American context represent areas for future research.

Objective: To investigate the prevalence of occupational diseases and treatment implementation in migrant workers in Hunan, China, and to provide a scientific basis for related departments to develop preventive and treatment measures and social security system for migrant workers. Methods: A retrospective investigation was performed in 2015 to collect the information of occupational diseases in migrant workers, and age, type of work, type of occupational disease, and implementation of employment injury insurance for occupation diseases were analyzed. Results: The migrant workers with occupational diseases accounted for 50.43% (11 280/22 368) of all patients with occupational diseases in Hunan, among whom 99.4% (11 212/11 280) were male workers. The mean age of migrant workers with occupational diseases was 55 years. The types of occupational diseases involved 6 categories such as occupational pneumoconiosis and occupational skin diseases, totaling 42 legal occupational diseases; 98.31% of all migrant workers (11 089/11 280) had occupational pneumoconiosis. The main types of work were underground coal miners (62.42%) , heading drivers (29.79%) , and haulage workers (2.20%) in coal mines and non-coal mines. A total of 27.25% migrant workers with occupational diseases (2 072/7 605) enjoyed employment injury insurance, and 20.84% (1 585/7 605) did not receive any medical or life compensations. Conclusion: The occupational diseases in migrant workers in Hunan are mainly pneumoconiosis, and a large proportion of those with occupational diseases do not enjoy implementation of treatment. Coal mines and non-coal mines are the high-risk areas for occupational diseases in migrant workers and should be the focus of prevention and control.

Because of the uncertainty about an E.M.F. - health link, the main effort is to determine the probability and seriousness of E.M.F. hazard and to realize an accurate risk assessment at workplace, which is one of the main objectives pursued by I.N.A.I.L. Technical Advisory Department for Risk Assessment and Prevention. Moreover, in this paper it is also reported the state of advancement of Italian legislation on health protection against non ionizing radiations at workplace in view of the new European Directive (2004/40/C.E.).

The occurrence, prevalence, and distribution patterns of acute bee paralysis virus (ABPV), black queen cell virus (BQCV), chronic bee paralysis virus (CBPV), deformed wing virus (DWV), Kashmir bee virus (KBV), and sacbrood virus (SBV) were investigated in 90 Austrian honeybee colonies suffering from symptoms of depopulation, sudden collapse, paralysis, or dark coloring by employing reverse transcription-PCR. Infestation with parasites was also recorded. The samples originated from all parts of Austria. The most prevalent virus was DWV, present in 91% of samples, followed by ABPV, SBV, and BQCV (68%, 49%, and 30%, respectively). CBPV was detected in 10% of colonies, while KBV was not present in any sample. In most samples, more than one virus was identified. The distribution pattern of ABPV, BQCV, CBPV, and SBV varied considerably in the different geographic regions investigated, while DWV was widespread in all Austrian federal states. In bees that showed dark coloring and disorientation, CBPV was always detected. Simultaneous infections of DWV and ABPV were most frequently observed in colonies suffering from weakness, depopulation, and sudden collapse. Bees obtained from apparently healthy colonies within the same apiaries showed a similar distribution pattern of viruses; however, the relative virus load was 10 to 126 times lower than in bees from diseased colonies. A limited number of bee samples from surrounding central European countries (Germany, Poland, Hungary, and Slovenia) were also tested for the presence of the above viruses. Variances were found in the distribution of BQCV and SBV. PMID:16597939

Cigarette smoking and occupational exposure to respiratory irritants are the major riskfactors for chronic obstructive pulmonary disease (COPD), which is characterized by small-airway obstruction and destruction of pulmonary parenchyma: emphysema. We studied two groups of subjects: one exposed and the other one not-exposed to respiratory irritants, to investigate the relationship, if any, between occupational exposure and COPD. Subjects underwent high-resolution computed tomography-density mask of the chest to quantify pulmonary emphysema, pulmonary function tests, sputum induction and analysis for cell counts and measurements of metalloproteinase (MMP)-9 and its tissue inhibitor TIMP-1. Subjects with occupational exposure to respiratory irritants had higher residual volume and functional residual capacity, higher total inflammatory cells and neutrophils in induced sputum. By contrast, sputum levels of MMP-9, TIMP-1 and MMP-91TIMP-1 ratio did not differ between the 2 groups. We conclude that sputum induction and analysis could be a useful and non-invasive tool to study and follow subjects with occupational exposure to respiratory irritants.

An artificial intelligence expert-based system for facilitating the clinical recognition of occupational and environmental factors in lung disease has been developed in a pilot fashion. It utilizes a knowledge representation scheme to capture relevant clinical knowledge into structures about specific objects (jobs, diseases, etc) and pairwise relations between objects. Quantifiers describe both the closeness of association and risk, as well as the degree of belief in the validity of a fact. An independent inference engine utilizes the knowledge, combining likelihoods and uncertainties to achieve estimates of likelihood factors for specific paths from work to illness. The system creates a series of "paths," linking work activities to disease outcomes. One path links a single period of work to a single possible disease outcome. In a preliminary trial, the number of "paths" from job to possible disease averaged 18 per subject in a general population and averaged 25 per subject in an asthmatic population. Artificial intelligence methods hold promise in the future to facilitate diagnosis in pulmonary and occupational medicine.

Full Text Available Noise exposure might be a risk factor for ischemic heart disease (IHD. Unlike residential exposure, however, evidence for occupational noise is limited. Given that high-quality quantitative synthesis of existing data is highly warranted for occupational safety and policy, we aimed at conducting a systematic review and meta-analysis of the risks of IHD morbidity and mortality because of occupational noise exposure. We carried out a systematic search in MEDLINE, EMBASE, and on the Internet since April 2, 2015, in English, Spanish, Russian, and Bulgarian. A quality-scoring checklist was developed a priori to assess different sources of methodological bias. A qualitative data synthesis was performed. Conservative assumptions were applied when appropriate. A meta-analysis was not feasible because of unresolvable methodological discrepancies between the studies. On the basis of five studies, there was some evidence to suggest higher risk of IHD among workers exposed to objectively assessed noise >75–80 dB for <20 years (supported by one high, one moderate, and one low quality study, opposed by one high and one moderate quality study. Three moderate and two low quality studies out of six found self-rated exposure to be associated with higher risk of IHD, and only one moderate quality study found no effect. Out of four studies, a higher mortality risk was suggested by one moderate quality study relying on self-rated exposure and one of high-quality study using objective exposure. Sensitivity analyses showed that at higher exposures and in some vulnerable subgroups, such as women, the adverse effects were considerably stronger. Despite methodological discrepancies and limitations of the included studies, occupational noise appeared to be a risk factor for IHD morbidity. Results suggested higher risk for IHD mortality only among vulnerable subgroups. Workers exposed to high occupational noise should be considered at higher overall risk of IHD.

Occupational skin disease (OSD) is a common occupational disease. Although primary prevention strategies are known, OSDs remain prevalent in a variety of work environments including the service sector (restaurant/food services, retail/wholesale, tourism/hospitality and vehicle sales and service). To obtain information about awareness and prevention of OSD in the service sector. Focus groups and a survey were conducted with two groups. The first consisted of staff of the provincial health and safety association for the service sector and the second group comprised representatives from sector employers. Focus groups highlighted key issues to inform the survey that obtained information about perceptions of awareness and prevention of OSD and barriers to awareness and prevention. Both provincial health and safety association staff and sector employer representatives highlighted low awareness and a low level of knowledge of OSD in the sector. Barriers to awareness and prevention included a low reported incidence of OSD, low priority, lack of training materials, lack of time and cost of training, lack of management support and workplace culture. A starting point for improving prevention of OSD in the service sector is increased awareness. Identification of the barriers to awareness and prevention will help to shape an awareness campaign and prevention strategies. Building on existing experience in Europe will be important. © The Author 2016. Published by Oxford University Press on behalf of the Society of Occupational Medicine. All rights reserved.

This is the first book to examine the latest methods in analyzing presence/absence data surveys. Using four classes of models (single-species, single-season; single-species, multiple season; multiple-species, single-season; and multiple-species, multiple-season), the authors discuss the practical sampling situation, present a likelihood-based model enabling direct estimation of the occupancy-related parameters while allowing for imperfect detectability, and make recommendations for designing studies using these models. It provides authoritative insights into the latest in estimation modeling; discusses multiple models which lay the groundwork for future study designs; addresses critical issues of imperfect detectibility and its effects on estimation; and explores the role of probability in estimating in detail.
Teenage girls and young women, whose job it was to apply luminous paint containing radium to watches during World War I, were among the first industrial radiation poisoning victims in the United States. This paper recounts both the story of how their afflictions became recognized occupational diseases and of the tangled web of governmental-industrial-academic collusion (largely based on industrial funding of research and experts) which delayed this recognition. It shows how these industrial-academic arrangements led to the establishment of the major academic training programs in occupational medical and industrial hygiene still in existence. Using historical sources, this study provides evidence of moral lapses by medical researchers, including directly lying to the victims, withholding data on the true extent of illness and radiation contamination and of distorting evidence. The pivotal role of the Consumers League and of Dr. Alice Hamilton in establishing the truth of the radium dial painting poisonings is discussed

The high incidence of chronic digestive diseases is recorded in chemical industry workers exposed to the isolated action of noxious substances. The aim of the investigation was to make a hygienic assessment of the risk for occupational digestive diseases in chemical industry workers exposed to a combination of noxious drugs. The working conditions and the prevalence of digestive diseases were studied in 4120 workers engaged in chemical and auxiliary processes. Under the isolated action of noxious substances, the workers had an average of 35% increase in the incidence of digestive diseases than unexposed ones (p 4.0-11.1 and 3.5-10.7 times higher, respectively (p < 0.05) than in the unexposed subjects.
Conclusion: Zoonotic TB is a significant public health issue among professionally exposed groups in Peshawar, Pakistan, and suggests a need for further detailed investigations of the disease in this and similar areas.

Full Text Available Background: An increased incidence of non-Hodgkin’s lymphoma (NHL has been reported in farmers and other occupational groups working with pesticides. In these individuals, an increased prevalence of the chromosomal translocation t(14;18(q32;q21, one of the most common chromosomal abnormalities in NHL, has been detected in peripheral blood lymphocytes. This translocation juxtaposes the antiapoptotic BCL2 protein to the immunoglobulin heavy chain gene locus (IGH leading to overexpression of BCL2. This causes an increase in cell survival, paving the way for malignant transformation. Aim of the study: The present study aimed to evaluate the association between the occurrence of the chromosomal translocation t(14;18 and occupational exposure to pesticides among a group of Jordanian farmers. Methods: A total of 192 male subjects including 96 agricultural workers and 96 control subjects participated in this study. BCL2-IGH t(14;18 fusions were detected by a nested polymerase chain reaction (PCR assay targeting the major breakpoint region (MBR. Results: We found that occupational exposure to pesticides in open-field farming and insecticide used on animals increased the frequency of the chromosomal translocation t(14;18. Farmers occupationally exposed to pesticides and insecticide were 13.5 times more likely to harbor t(14;18. 63.5% (61 of 96 of farmers compared to 11.5% (11 of 96 of controls carried the translocation (odds ratio: 13.5; 95% confidence interval (CI = 6.3–28.6. We ruled out the influence of possible confounding factors such as age, duration of sun exposure, alcohol intake, smoking, and use of personal protective equipment. Conclusion: Our results indicate that pesticides increased the frequency of chromosomal translocation in the 14q32 region. Accordingly, the presented data agrees with previous suggestions from the literature that pesticides might be involved in the development of NHL through the t(14;18 pathway. Keywords

This paper examines the history of an occupational disease which has now disappeared: acroosteolysis of manual tank cleaners in the production of polyvinyl chloride (PVC), which is a rare disease characterized by destructive alterations of the distal phalanges of the hands. All the available literature on this disease was examined. The history of acroosteolysis was studied within the general framework of the history of the discovery of adverse health effects of exposure to vinyl chloride, and this history was studied up to the end of the 1960's. The disease was observed for the first time in mid-1963 in Belgium (Jemeppe) in a chemical plant operated by Solvay, and affected two workers whose job was the manual cleaning of vessels used for the polymerization of vinyl chloride; similar cases occurred in almost all PVC production plants all over the world, but not in the plants where the main activity was the production of vinyl chloride monomer (VCM). Little more than one hundred cases are described in the scientific literature, and this number increases by a few dozen if we consider known but unpublished cases. These figures confirm the rarity of the disease, which peaked at the end of the 1960's and disappeared during the 1970's, probably due to the complete elimination of manual reactor cleaning. Observation of the disease lasted no more than fifteen years and the disease was not replicated in experimental conditions on animals. The disease was clinically characterized, had a short latency (from several months to several years), was rare and unequivocally linked to the manual cleaning of PVC polymerization tanks. However many questions still remain open: the period when the disease first appeared (many years after the start of PVC production in the world), the etiology of the disease (the most accredited hypothesis considers three concomitant factors: a chemical factor--one of the many substances used during polymerization, and particularly vinyl chloride monomer

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality in both industrialized and developing countries. Cigarette smoking is the major risk factor for COPD. However, relevant information from the literature published within the last years, either on general population samples or on workplaces, indicate that about 15% of all cases of COPD is work-related. Specific settings and agents are quoted which have been indicated or confirmed as linked to COPD. Coal miners, hard-rock miners, tunnel workers, concrete-manufacturing workers, nonmining industrial workers have been shown to be at highest risk for developing COPD. Further evidence that occupational agents are capable of inducing COPD comes from experimental studies, particularly in animal models. In conclusion, occupational exposure to dusts, chemicals, gases should be considered an established, or supported by good evidence, risk factor for developing COPD. The implications of this substantial occupational contribution to COPD must be considered in research planning, in public policy decision-making, and in clinical practice.

Full Text Available Our aim was to study how significant psychosocial factors are in occupational stress and cardiovascular diseases evolvement in workers employed at petrochemical production; we also intended to work out a set of preventive measures. Our hygienic and social-psychological research enabled us to detect factors causing stress evolvement in workers employed at petrochemical production. These factors included chemical impact, noise, unfavorable microclimate, labor hardness and labor intensity. High level of risk for their own lives and responsibility for safety of others, as well as work under time deficiency conditions with increased responsibility for the final results, were the most significant psychosocial factors for workers. In the course of questioning we detected that 74 % machine operators, 63 % tool men working with controllers and automatic devices, and 57 % repairmen mentioned having stress at work. Here 38 % workers gave a subjective estimation of their professional activity as having apparent "stress nature". The questioning revealed that 48 % workers with various occupations had increased parameters as per anxiety scale (HADS; 23 % workers had increased parameters as per depressions scale (HADS. Primary hypertension was the most widely spread nosologic form among chronic non-infectious diseases; it was found in 46.1 % operators and in 45.2 % repairmen dealing with processing stations repair. 30.1 % tool men working with controllers and automatic devices had average occupational causation of primary hypertension by production factors. We detected direct relation between hyperlipidemia and age and working period. We created foundation for preventive measures and worked out a program aimed at increasing resistance to stress at corporate and individual level. It will provide significant social effect and later on economic one. To overcome social stress we need to create safe working conditions at workplaces and to increase labor motivation

The cumulative effect of solar ultraviolet (UV) radiation is responsible for the worldwide increase in non-melanoma skin cancer, a category that includes squamous cell carcinoma and its precursors (the actinic keratoses) as well as basal-cell carcinoma. Non-melanoma skin cancer is the most common type of cancer in areas of the world with a light-skinned population. The occupational exposure to UV radiation is high in many outdoor occupations; recent studies suggest that persons working in such occupations are more likely to develop non-melanoma skin cancer. On the basis of a selective review of the literature, we present the current state of knowledge about occupational and non-occupational UV exposure and the findings of meta-analyses on the association of outdoor activity with non-melanoma skin cancer. We also give an overview of the current recommendations for prevention and for medicolegal assessment. Recent meta-analyses have consistently documented a significantly higher risk of squamous cell carcinoma of the skin among persons who work outdoors (odds ratio [OR] 1.77, 95% confidence interval [CI] 1.40-2.22, pmelanoma skin cancer in persons with high occupational exposure to UV radiation should be reported as an occupational disease under § 9, paragraph 2 of the Seventh Book of the German Social Code (Sozialgesetzbuch, SGB VII). Preventive measures are urgently needed for persons with high occupational exposure to UV radiation.
In this commentary, the pathogenesis of alveolitis is examined and elucidated by animal models. The use of broncho alveolar lavage (BAL) and Ga-67 citrate whole-body scanning as a measure of the activity of alveolar inflammation in workers is discussed. Gallium scan indices have been reported to be elevated in asbestosis, silicosis, and coal workers' pneumoconiosis; diseases which may now be evaluated at earlier, potentially reversible stages. Research in emphysema and other lung diseases associated with α 1 antitrypsin deficiency may help explain why coal miners develop focal emphysema. Furthermore, investigation of genetic factors may reveal why workers with similar exposures have a different susceptibility for the development of pneumoconiosis or lung cancer. Occupational asthma may not respond to removal of the worker from exposure because reactive airways may be a predisposing factor for chronic ashthma and chronic obstructive lung disease. A continuing challenge will be disease risk in new industries such as electronics and alternate energy industries and new diseases in worker groups not previously studied, such as the variety of pneumoconioses among dental laboratory technicians who work with exotic metal alloys. 52 references

Full Text Available Subcutaneous mycoses are not rare in Latin America. In Brazil, sporotrichosis was once almost exclusively found in rural areas, but in recent years it changed its profile and has been more frequent among urban adults. Cutaneous sporotrichosis is acquired from saprophytic dimorphic fungus Sporothrix schenckii usually found in soil, vegetation, and especially decaying organic matter in tropical, subtropical, and humid environments through cutaneous inoculation. The fungus abundantly grows on dead wood. Sporotrichosis is a health hazard present in florists, gardeners and other urban professions in contact with plants and the infection is increasingly seen as an occupational disease. The patient had been hurt in the finger by a thorn of Bouganvillea tree and a primary ulcer started.

General issues of industrial health are raised in relation to the production of asbestos and asbestos-related diseases in South Africa., A historical analysis of these diseases and their control in Britain demonstrates some general problems of occupational diseases with long incubation periods and their implications for capital and labor. In order to understand the role of the research establishment, an attempt is made to situate the state in the conflict between capital and labor. The terms and weapons of this ideological arena are investigated. The South African situation is then discussed. Its evident weaknesses--the lack of statutory limits on exposure, capital's responsibility for monitoring exposure and health, the inefficiency of the state inspection, and the meagerness and racial disparities in compensation--are related to the weakness of organized labor. These weaknesses are linked to the movement of certain industrial processes, finally acknowledged as unsafe by most academic research, away from the developed countries. In these countries, the strength of labor and environmental organizations has caused a decline in capitalist productivity.

Erionite, a mineral series within the zeolite group, is classified as a Group 1 known respiratory carcinogen. This designation resulted from extremely high incidences of mesothelioma discovered in three small villages from the Cappadocia region of Turkey, where the disease was linked to environmental exposures to fibrous forms of erionite. Natural deposits of erionite, including fibrous forms, have been identified in the past in the western United States. Until recently, these occurrences have generally been overlooked as a potential hazard. In the last several years, concerns have emerged regarding the potential for environmental and occupational exposures to erionite in the United States, such as erionite-bearing gravels in western North Dakota mined and used to surface unpaved roads. As a result, there has been much interest in identifying locations and geologic environments across the United States where erionite occurs naturally. A 1996 U.S. Geological Survey report describing erionite occurrences in the United States has been widely cited as a compilation of all US erionite deposits; however, this compilation only focused on one of several geologic environments in which erionite can form. Also, new occurrences of erionite have been identified in recent years. Using a detailed literature survey, this paper updates and expands the erionite occurrences database, provided in a supplemental file (US_erionite.xls). Epidemiology, public health, and natural hazard studies can incorporate this information on known erionite occurrences and their characteristics. By recognizing that only specific geologic settings and formations are hosts to erionite, this knowledge can be used in developing management plans designed to protect the public.

Cross-sectional epidemiologic study. To evaluate the interaction between known genetic risk factors and whole-body vibration for symptomatic intervertebral disc disease (IDD) in an occupational sample. Risk factors of IDD include, among others, whole-body vibration and heredity. In this study, the importance of a set of known genetic risk factors and whole-body vibration was evaluated in an occupational sample of train engineers and sedentary controls. Eleven variations in 8 genes (COL9A2, COL9A3, COL11A2, IL1A, IL1B, IL6, MMP-3, and VDR) were genotyped in 150 male train engineers with an average of 21-year exposure to whole-body vibration and 61 male paper mill workers with no exposure to vibration. Subjects were classified into IDD-phenotype and asymptomatic groups, based on the latent class analysis. The number of individuals belonging to the IDD-phenotype was significantly higher among train engineers (42% of train engineers vs. 17.5% of sedentary workers; P = 0.005). IL1A -889T allele represented a significant risk factor for the IDD-phenotype both in the single marker allelic association test (P = 0.043) and in the logistic regression analysis (P = 0.01). None of the other allele markers was significantly associated with symptoms when analyzed independently. However, for all the SNP markers considered, whole-body vibration represents a nominally significant risk factor. The results suggest that whole-body vibration is a risk factor for symptomatic IDD. Moreover, whole-body vibration had an additive effect with genetic risk factors increasing the likelihood of belonging to the IDD-phenotype group. Of the independent genetic markers, IL1A -889T allele had strongest association with IDD-phenotype.

According to official statistics, men suffer more occupational diseases (OD) than women. Nevertheless, the unequal distribution and participation in the labor markets between men and women should be kept in mind. The purpose was to assess the gender impact in the recognition of OD in Spain, examining interaction and confounding factors. An incidence study of the occupational diseases declared through the official OD reporting forms from 1999 to 2009, provided by the General Subdirectorate of Social and Labor Statistics of the Ministry of Employment and Social Security, was conducted. The variables included were: reporting year, sex, age, occupation and economic activity of the company. Rates and crude relative risks (cRR) by these variables were calculated. Adjusted RR were also computed by using multivariate Poisson regression. During the study period a total of 243,310 OD were reported in Spain, with a sex ratio of men to women of 1.07. Correlation existed between occupation and business activity, thus the OD rates and RR were computed by these variables separately. By occupation, men had a crude RR of 1.067 (95%CI:1.058 to 1.076) versus women, while wen the analysis was adjusted by all the variables, the RR was 0.507 (95%CI:0.502 to 0.512). By economic activity of the company, the sense of risk was reversed too in the adjusted analysis (cRR=1.065, 95%CI:1.056 to 1.074 versus 0.632, 95%CI:0.626 to 0.638). Although crude OD rates were lower in women than in men during the period 1999-2009 in Spain, when these rates were adjusted by company activity or worker occupation, age and year of OD declaration, RRs become almost 50% higher in women than in men for the majority of occupations and types of company activity.

The study covered data on 977 cases of occupational diseases in 615 workers of nonferrous metallurgy in Kolsky Transpolar area. Findings are high risk of occupational diseases in workers engaged into electrolysis production of aluminium, all nickel reprocessing and pyrometallic copper reprocessing (GR 7.02-10.0). Electrolysis operators and anode operators of aluminium production are more prone to occupational diseases, with bone and muscular disorders (46.8%) prevalent in the morbidity structure. Respiratory diseases are more prevalent (68.2-100%) in the occupational morbidity structure of copper-nickelindustry workers. Conclusion is made on mandatory improvement of the work conditions and more effective individual protective means against occupational hazards in workers of nonferrous metallurgy in Kolsky Transpolar area.

The objective of the present study was to characterize lung function (under off-drug conditions in early-stage PD patients at baseline and then again two years later.Forty-one early-stage PD patients (mean ± SD age: 61.7 ± 7.7; mean ± SD disease duration: 1.9 ± 1.7 years were prospectively enrolled and compared with 36 age-matched healthy controls. Neurological evaluations and pulmonary function testing were performed in the off-drug condition at the inclusion visit and then two years later.Pulmonary function testing did not reveal any restrictive or obstructive disorders; at baseline, inspiratory muscle weakness was the only abnormality observed in the PD group (in 53.7% of the patients, vs. 25% in controls; p = 0.0105. The PD patients had a lower mean maximal inspiratory mouth pressure than controls and a lower sniff nasal inspiratory pressure. Two years after the initiation of chronic treatment with antiparkinsonian medications, the maximal inspiratory mouth pressure and the sniff nasal inspiratory pressure tended to be higher. Lastly, overall motor outcomes were not significantly worse in patients with inspiratory muscle weakness than in patients without inspiratory muscle weakness.Inspiratory muscle weakness seems to be common in patients with early-stage PD, and was seen to be stable over a two-year period. Additional long-term follow-up studies are required to specify the impact of this new feature of PD.

Various stresses are considered to be involved in the development of gastric and duodenal ulcers. We interviewed patients of either gastric ulcer group (GU) or duodenal ulcer group (DU) with regular occupation who were admitted to our Psychosomatic Illness Department in order to examine the differences in the characteristics of their stress and developmental factors of their diseases between the two groups. Developmental factors were scored for comparison. The following results were obtained. Though group DU was generally younger than group GU, it tended to have a greater number of episodes. No significant difference was found between the two groups in living habits, life history, or familial, social and physical environments. However, group DU had greater stress than group GU in the working environment. A significantly greater number of patients in group DU smoked and had problems in personal relations as compared with GU. There was a significant correlation between smoking habit and stressfulness of the working environment in both groups. In group DU, there was a significant correlation between the father-child relationship and personal relations. In group DU, a significant number of those who had problems in the relation with their superiors at work had problems in the father-child relation. These findings show that patients with duodenal ulcer had more problems in the working environment, particularly in personal relations, than those with gastric ulcer, and smoking habit appears to accelerate the development of the diseases. Also, a possible association was suggested between problems of personal relations at work and the history of growth.

The healthcare sector ranked in second place among economic sectors in the Czech Republic, with about 11.4 % of all occupational diseases in 2009. Skin diseases constituted about 20 % of all occupational diseases. The aim of this study was to analyze the causes and trends in allergic and irritant-induced skin diseases in the healthcare sector. The data concerning occupational skin diseases (Chapter IV of the Czech List of Occupational Diseases, non-infectious skin illnesses) in the healthcare sector were analyzed from the Czech National Registry of Occupational Diseases from 1997 until 2009. The trends in the total counts and most frequent causes were evaluated. During the past 13 years, a total of 545 skin diseases were acknowledged in healthcare workers. Allergic contact dermatitis was diagnosed in 464 (85 %), irritant contact dermatitis in 71 (13 %) and contact urticaria in 10 subjects (2 %). Ninety-five percent of the patients were females. The overall incidence in individual years varied between 1.0 and 2.9 cases per 10,000 full-time employees per year. Disinfectants were the most frequent chemical agents causing more than one third of all allergic skin diseases (38 %), followed by rubber components (32 %) and cleaning agents (10 %). A general downward trend of diagnosed cases of occupational skin diseases in heath care workers in the Czech Republic over the past 13 years was demonstrated.
Dozens cases of diseases are submitted to judgement as occupational diseases every year in the Czech Republic. Patients or attending physicians suggest that these cases are caused by occupational ionizing radiation. Only a part of these cases is qualified as occupational disease. The term 'occupational disease' is rather a juridical term which underlies the right to financial compensation. The causal association with exposure to ionizing radiation cannot be indisputably verified by expert medical opinion. Most diseases, which are proposed as occupational disease, are malignant tumors of the lungs. Total majority of judged cases are lung cancers from radioactive agents. In 2002, a total of 33 cases of lung cancer in former uranium or ore miners have been acknowledged as occupational diseases. The decision about occupational disease is derived from probabilistic approach based on estimation of probability of causation of irradiation on disease origin (methodical guideline No. 15 of Ministry of Health Bulletin, part 9, 1998). The presented paper gives a general information about all judged causes of occupational diseases in former uranium and ore miners in the Czech Republic in 2002. A total of 72 cases were submitted to judgement of conditions of disease origin to the National Radiation Protection Institute in 2002. 67 cases were lung cancers, 1 case was chronic myeloid leukemia, acute myeloid leukemia, basaliom, cancer of larynx and cancer of nasal septum. The probability of causation was assessed as prevailing in 32 cases of lung cancer, borderline in 5 cases and low in other 30 cases of lung cancer. The probability of causation was prevailing in both cases of myeloid leukemia. (author)

Full Text Available Occupational diseases affect more and more people every year. According to the International Labour Organization (ILO, in 2000 an estimated amount of at least 160 million people became ill as a result of occupational-related hazards or injuries. Globally, occupational deaths, diseases and injuries account for an estimated loss of 4% of the Gross Domestic Product. Important substances that are related to occupational diseases are isocyanates and their products. These substances, which are used in a lot of different industrial processes, are not only toxic and irritant, but also allergenic. Although the exposure to higher concentrations could be monitored and restricted by technical means, very low concentrations are difficult to monitor and may, over time, lead to allergic reactions in some workers, ending in an occupational disease. In order to prevent the people from sickening, the mechanisms underlying the disease, by patho-physiological and genetical means, have to be known and understood so that high risk groups and early signs in the development of an allergic reaction could be detected before the exposure to isocyanates leads to an occupational disease. Therefore, this paper reviews the so far known facts concerning the patho-physiologic appearance and mechanisms of isocyanate-associated toxic reactions and possible genetic involvement that might trigger the allergic reactions.

Refractory coeliac disease, enteropathy associated T-cell lymphoma and small bowel adenocarcinoma are rare but prognostically important complications in coeliac disease. To analyse potential changes in occurrence of complicated coeliac disease over the last 25 years. One thousand one hundred and thirty eight patients were included and evaluated based on their time of first presentation at the Medical University of Vienna, Austria. Occurrences of refractory coeliac disease and associated malignancies were evaluated for 5-year intervals from January 1990 until December 2014 and were compared over time. 2.6% (n = 29) were diagnosed with refractory coeliac disease (females 65.6%, mean age at diagnosis 62.8 years). The proportion of those patients was 2.6%, 3.1%, 3.3%, 2.7% and 0.5% for the 5 year intervals from 1990 onwards. Thus, the number of refractory cases has been decreasing since 2000 (P = 0.024). The number of patients presenting with lymphoma (n = 7) was 0.6%, 0.4%, 1.1%, 0.8% and 0% from 1990 to 2014. Similarly the number of patients with adenocarcinoma (n = 4) decreased to 0% until 2014. Overall mortality in patients suffering from refractory disease was 48%. Of all patients diagnosed with lymphoma 71.4% died with a 5-year survival rate of 28.6%. Over the past 15 years the occurrence of complicated coeliac disease has been decreasing. This possibly reflects a higher awareness of coeliac disease and optimised diagnosis and treatment with avoidance of long-term immunological disease activity. Symptomatic disease and a delay in diagnosis are risk factors for refractory coeliac disease and related cancer. © 2016 John Wiley & Sons Ltd.

Full Text Available Damage to the lungs caused by dusts or fumes or noxious substances inhaled by workers in certain specific occupation is known as occupational lung disease. Recognition of occupational lung disease is especially important not only for the primary worker, but also because of the implications with regard to primary and secondary disease prevention in the exposed co-workers. Although many of the disorders can be detected on chest radiography, high-resolution computed tomography (HRCT is superior in delineating the lung architecture and depicting pathology. The characteristic radiological features suggest the correct diagnosis in some, whereas a combination of clinical features, occupational history, and radiological findings is essential in establishing the diagnosis in others. In the presence of a history of exposure and consistent clinical features, the diagnosis of even an uncommon occupational lung disease can be suggested by the characteristic described HRCT findings. In this article, we briefly review the HRCT appearance of a wide spectrum of occupational lung diseases.

There are several clinical reports about the co-occurrence of autosomal dominant polycystic kidney disease (ADPKD) and connective tissue disorders. A simultaneous occurrence of osteogenesis imperfecta (OI) type I and ADPKD has not been observed so far. This report presents the first patient with OI type I and ADPKD. Mutational analysis of PKD1 and COL1A1 in the index patient revealed a heterozygous mutation in each of the two genes. Mutational analysis of the parents indicated the mother as a carrier of the PKD1 mutation and the father as a carrier of the COL1A1 mutation. The simultaneous occurrence of both disorders has an estimated frequency of 3.5:100 000 000. In singular cases, ADPKD can occur in combination with other rare disorders, e.g. connective tissue disorders.
Full Text Available Accidents are among the most important problems of both the developed and the developing countries. Individual factors and personality traits are the primary causes of human errors and contribute to accidents. The present study aims to investigate the relationship between the components of the five-factor model of personality and the occurrence of occupational accidents in industrial workers. The independent T-test indicated that there is a meaningful relationship between the personality traits and accident proneness. In the two groups of industry workers injured in occupational accidents and industry workers without any occupational accidents, there is a significant relationship between personality traits, neuroticism (p=0.001, openness to experience (p=0.001, extraversion (p=0.024 and conscientiousness (p=0.021. Nonetheless, concerning the personality trait of agreeableness (p = 0.09, the group of workers with accidents did not differ significantly from the workers without any accidents. The results showed that there is a direct and significant relationship between accident proneness and the personality traits of neuroticism and openness to experience. Furthermore, there is a meaningful but inverse correlation between accident proneness and the personality traits of extraversion and conscientiousness, while there was no relationship between accident proneness and the personality trait of agreeableness.
Full Text Available Abstract Background The evidence for associations between occupational factors and the risk of Parkinson's disease (PD is inconsistent. We assessed the risk of PD associated with various occupational factors in Japan. Methods We examined 249 cases within 6 years of onset of PD. Control subjects were 369 inpatients and outpatients without neurodegenerative disease. Information on occupational factors was obtained from a self-administered questionnaire. Relative risks of PD were estimated using odds ratios (ORs and 95% confidence intervals (CIs based on logistic regression. Adjustments were made for gender, age, region of residence, educational level, and pack-years of smoking. Results Working in a professional or technical occupation tended to be inversely related to the risk of PD: adjusted OR was 0.59 (95% CI: 0.32-1.06, P = 0.08. According to a stratified analysis by gender, the decreased risk of PD for persons in professional or technical occupations was statistically significant only for men. Adjusted ORs for a professional or technical occupation among men and women were 0.22 (95% CI: 0.06-0.67 and 0.99 (0.47-2.07, respectively, and significant interaction was observed (P = 0.048 for homogeneity of OR. In contrast, risk estimates for protective service occupations and transport or communications were increased, although the results were not statistically significant: adjusted ORs were 2.73 (95% CI: 0.56-14.86 and 1.74 (95% CI: 0.65-4.74, respectively. No statistical significance was seen in data concerning exposure to occupational agents and the risk of PD, although roughly a 2-fold increase in OR was observed for workers exposed to stone or sand. Conclusion The results of our study suggest that occupational factors do not play a substantial etiologic role in this population. However, among men, professional or technical occupations may decrease the risk of PD.

The purpose of this study was to investigate the utilization of occupational therapy services in persons with Charcot-Marie-Tooth (CMT) disease, to better understand if services are being provided, the types of interventions being provided, and satisfaction of services. Using survey methods, an online questionnaire was made available to persons with CMT listed on association websites worldwide. One hundred and fifteen persons with CMT, residing in all geographical regions within the United States and seven other countries participated in the study. Around half of all participants had received occupational therapy services. Twelve interventions were identified as being provided for persons with CMT. Although the majority of individuals receiving occupational therapy services did not feel like it improved their quality of life, the majority of individuals would recommend occupational therapy services to others and would return to an occupational therapist. Of those participants not receiving occupational therapy, the majority felt they would benefit from occupational therapy services. The results suggest that occupational therapy services are not being well utilized for this population. A low response rate limits generalization, thus further research is necessary.

To investigate the association of Parkinson disease (PD) with education and occupations using a case-control study design. The authors used the medical records-linkage system of the Rochester Epidemiology Project to identify all subjects who developed PD in Olmsted County, MN, from 1976 through 1995. Each incident case was matched by age (+/-1 year) and sex to a general population control. The authors collected information about education and occupations using two independent sources of data: a review of the complete medical records in the system and a telephone interview. Occupations were coded using the 1980 Standard Occupational Classification. Subjects with 9 or more years of education were at increased risk of PD (OR = 2.0; 95% CI = 1.1 to 3.6; p = 0.02), and there was a trend of increasing risk with increasing education (test for linear trend, p = 0.02; medical records data). Physicians were at significantly increased risk of PD using both sources of occupational data. By contrast, four occupational groups showed a significantly decreased risk of PD using one source of data: construction and extractive workers (e.g., miners, oil well drillers), production workers (e.g., machine operators, fabricators), metal workers, and engineers. These associations with increased or decreased risk did not change noticeably after adjustment for education. Subjects with higher education and physicians have an increased risk of Parkinson disease (PD), while subjects with some occupations presumed to involve high physical activity have a decreased risk of PD.

Full Text Available First described in 1998, the marsh tapaculo (Scytalopus iraiensis is an endangered bird of the family Rhinocryptidae. It is endemic to Brazil and is restricted to the wet flood plains of rivers and streams. Due to its cryptic habits and environments of occurrence, information available on its biology, natural history and distribution is scarce. We compiled occurrence records (99 records, delimited the extent of occurrences (296,584 km2, calculated the area of occupancy (84 km2, estimated territory size (5,313 ± 1,201 m2 per pair, population density (3.76 ± 0.85 individuals per hectare, and population size (31,584 ± 7,140 mature individuals of marsh tapaculo. The species was recorded in marshes associated to four types of vegetation and in four ecological zones. This new information is extremely important to support revaluation of the species’ threat category and to enhance knowledge about this endemic and little known bird from Brazil.
Full Text Available Occupational diseases of respiratory tract are listed among 12 independent nosological unites at the registry of the Slovak republic, (tuberculosis and lung cancer due to chemical carcinogens were excluded and listed elsewhere.In the past 10 years approximately 100 new cases of newly detected professional respiratory diseases have been reported. They encompass about 10% of all occupational diseases, ranging from 5 to 7 of all the most frequent occupational diseases. Pneumoconiosis, allergic and lung cancer represent currently the most frequent and prognostical the most serious occupational diseases.Pneumoconiosis represents an acute and chronic lung disease caused by inhalation and retention of inorganic dust. Silicosis is the most frequently reported pneumoconiosis in our region. It is a progressive aseptic inflamation of lung intersticium, due to long term inhalation and deposition of mineral dust containing free crystalic SiO2 followed by a fibrotic remodeling.The x-ray manifestation without an obvious symptomatology at the beginning of disease is quite common for pneumoconiosis in general. Therefore international standards have been generated in order to describe, quantify these x-ray changes, s.c. ILO Classification. The standard chest radiograph is currently, at justified cases, accompanied by modern diagnostic CT related methods.Besides obligatory function diagnostics, microscopic and cultivation examinations, new modern facultative tests are also available for the purpose of differential diagnostics, allowing to identify diseases with a similar clinical pattern.

Cardiovascular disease is the first cause of morbidity and mortality worldwide. Among several known risk factors, researchers also focus their attention on the chronic exposure to air pollution. There is much evidence that exposure to air pollution, especially to ultrafine particles, can damage the endothelium and can favour cardiovascular diseases in the general population. Occupational exposition could be an additive risk factor for the cardiovascular system. This article presents a scientific review of the linkage between occupational exposure to air pollution and ischemic heart disease. A scientific review was undertaken, followed by PRISMA Statements. Observational studies were selected from several scientific databases, likesuch as Pubmed, Google Scholar, Nioshtic-2 and Reserchgate, searching for selected key words: police workers, professional drivers, mail carriers, filling station attendants, road cleaners, garage workers, motor vehicles and engine maintenance. All the key words were combined with "Boolean Operators" with the following words: cardiovascular (or cardiac) disease, cardiovascular function, cardiovascular system, ischemic heart disease, coronary disease, myocardial infarction. During the systematic research, the focus was on retrospective and prospective studies from January 1990 - December 2014. Both the retrospective and prospective studies showed an increased risk of ischemic heart disease in occupationally occupied people exposed to air pollution. Only one study presented a ly minor risk. The findings of this systematic review suggest a possible linkage between occupational exposure to urban air pollution, especially to motor exhaust and particulate, and ischemic heart disease.

Full Text Available Aim: Cardiovascular disease is a leading cause of morbidity and mortality in adults with type 2 diabetes mellitus. The aim of the present study was to test whether plasma basic fibroblast growth factor (bFGF levels predict future cardiovascular disease (CVD occurrence in adults from the Veterans Affairs Diabetes Trial. Methods: Nearly four- hundred veterans, 40 years of age or older, having a mean baseline diabetes duration of 11.4 years were recruited from outpatient clinics at six geographically distributed sites in the Veterans Affairs Diabetes Trial (VADT. Within the VADT, they were randomly assigned to intensive or standard glycemic treatment, with follow-up as much as seven and one-half years. Cardiovascular disease occurrence was examined at baseline in the patient population and during randomized treatment. Plasma bFGF was determined with a sensitive, specific two-site enzyme-linked immunoassay at the baseline study visit in all 399 subjects. Results: One hundred-five first cardiovascular events occurred in these 399 subjects. The best fit model of risk factors associated with the time to first cardiovascular disease occurrence (in the study over a seven and one-half year period had as significant predictors: prior cardiovascular event, (hazard ratio [HR] 3.378; 95% confidence intervals [CI] 3.079- 3.807; P < .0001, baseline plasma bFGF (HR 1.008; 95% CI 1.002-1.014; P =.01, age, (HR 1.027; 95% CI 1.004-1.051; P =.019, baseline plasma triglycerides, (HR 1.001; 95% CI 1.000-1.002; P =.02 and diabetes duration-treatment interaction (P =.03.

The monthly occurrence and mean age distribution of water-borne diseases in the Douala 4th District, Cameroon (1995-2006) were studied and probable causes of diseases spread were established. Diseases of interest included gastroenteritis, amoebic dysentery, typhoid fever and cholera. Water-borne disease occurrence was observed to follow a seasonal pattern with peaks occurring between the months of January and May followed by drops between June and October and rose again from November. Children below 5 years were found to be more vulnerable to diarrhoea, gastroenteritis, amoebic dysentery while persons between 15-44 years were more vulnerable to typhoid and cholera. Physico-chemically, water samples had turbidities varying between 5.5-86 NTU, pH values between 4.2 and 7.1 and zero residual chlorine. Bacteriological analysis showed that the total coliform count was averagely 74/100 ml, the faecal colform count was 43/100 ml and the faecal streptococci count was 27/100 ml. Lack of access to potable water, absence of sanitation facilities and environmental factors could be advanced as the probable causes of water-borne disease spread.
Full Text Available Abstract Background Primary biliary cirrhosis (PBC is a disease with genetic and environmental pathogenetic background. Chemicals, infectious agents, hormone therapy, reproductive history and surgical interventions have been implicated in the induction of PBC. Familial PBC has been documented in first degree relatives (FDR. Most cohort studies are genetically heterogeneous. Our study aimed to determine eventual lifestyle or disease associations and familial occurrence rates in a genetically homogeneous and geographically defined population of PBC patients. Methods 111 consenting PBC patients, were compared with 115 FDR and 149 controls matched for age, sex, Cretan origin and residence. All participants completed a questionnaire regarding demographics, lifestyle, medical, surgical and reproductive history. Significant variables on the univariate analysis were analyzed by multivariate analysis using a forward step-wise logistic regression model. Results Dyslipidaemia was found in 69.4% of patients, 60% of FDR and 40.9% of controls (p Conclusions Dyslipidaemia and autoimmune diseases were significantly increased not only in patients as expected but also in their FDR. An increased prevalence of malignancies was found in patients. Primary educational level, cholecystectomy and the presence of at least another autoimmune disease were found as putative risk factors for PBC. No association was found with smoking, urinary tract infection or reproductive history. The reported high familial occurrence of PBC could imply screening with AMA of FDR with at least another autoimmune disease.

The proportion of lung cancers with an occupational origin has been estimated to be between 10 and 20%. They are largely under-reported, as 60% are not compensated as occupational disease. Although most patients are not familiar with the process of compensation, other factors could explain this under-reporting. The aim of this study was to identify psychosocial factors that could impact patients with occupational lung cancer to claim for compensation. We conducted a case study involving semi-structured interviews with eight lung cancer patients enrolled in a cohort designed to systematically screen occupational exposures and propose claims for compensation to work-related cancer patients. Seven interviewed patients were familiar with occupational cancers, but most of them did not believe that past exposure could be related to their current disease. Patients associated compensation claims with a long and complex procedure for an abstract purpose. Several patients expressed a certain attachment to their employers. Interviewed patients often considered compensation claims to be a grievance procedure against the employers whom they did not consider to be responsible for their disease. Lung cancer is itself an obstacle to compensation considering the aggressive treatments and related adverse events, the poor medium-term prognosis and the predominant role of smoking in the etiology of the disease. Patients mentioned the financial compensation and the role of healthcare professionals as key elements to motivate them to claim for compensation.

Cosmetologists frequently develop occupational skin disease related to workplace exposures. The purpose of this study was to evaluate an educational intervention to increase cosmetology students' occupational skin disease knowledge and use of preventive practices. A quasi-experimental design was used to evaluate students' knowledge, behaviors, intentions, expectancies, and expectations. A 20-minute verbal presentation and printed two-page educational handout were provided for participants. Statistically significant increases in knowledge, frequency of glove use, and frequency of moisturizer use were found, but the frequency of handwashing did not increase. In addition, the Behavioral Strategies subscale, the Intention subscale, and the Expectancies subscale showed statistically significant improvements. The results of this study suggest an educational intervention can increase cosmetology students' knowledge of occupational skin diseases and their use of preventive strategies.
Full Text Available The paper outlines the data obtained in the course of long-term research dedicated to studying the extent to which re-productive system pathologies in workers with high-risk occupations are occupationally induced. Their peculiarity is joint impacts of various occupational factors (for example, impacts exerted by chemicals together with physical and biological factors, and labor hardness and intensity as well on a female body. Our research goal was to examine the extent to which reproductive system pathologies in workers with high-risk occupations were occupationally induced. To achieve it, we applied statistical estimate of correlation between health disorders and work. Our occupational group included a number of occupations with harmful or hazardous working conditions in civil en-gineering, metallurgy, chemical industry, polymer-processing industry, and health care as well. As a rule, working condi-tions class of workers from the examined groups varied from 3.1 to 3.3; and occupation with permissible working conditions were used as a comparative group. The research results revealed that there are certain occupations with high risk of reproductive health disorders evolvement and infants development pathologies evolvement. They are: – model makers and checkers in civil engineering and crane operators at a metallurgic plant; – analysts at chemical analysis laboratories, chemical engineers in chemical industry (including petrochemical plants, polymer-processing plants, and organic synthesis plants; – surgeons, obstetrician-gynecologists, midwives, surgical nurses working in in-patient departments. Estimate of correlation and occupational dependence of reproductive system diseases on working conditions revealed that women with harmful working conditions (3.1–3.3 hazard class had defective pregnancies or labor pathologies which had strong and average correlation with working conditions. Health disorders in newborns were estimated as per very

Occupational health and safety (OHS) services collect a wide range of data during health surveillance. To build a 'data warehouse' to make OHS data available for research and to investigate sector-specific health problems. Medical data were extracted, transformed and loaded into the data warehouse. After validation, data on lifestyle, categorized medication use, ICD-9-CM encoded sickness absences and health complaints, collected between 2010 and 2014, were analysed with logistic regression to compare proportions between employment sectors, taking into account age, gender, body mass index (BMI) and year of examination. The data set comprised 585000 employees. Average age and employment seniority were 39 ± 12 and 8 ± 9 years, respectively. BMI was 26 ± 5 kg/m(2). Health complaints, medication use and sickness absence significantly increased with BMI and age. The proportion of employees with health problems was highest in health care (64%), government (61%) and manufacturing (60%) and lowest in the service sector. In all sectors, 10% of workers reported locomotor health problems, apart from the service sector (8%) with similar results for medication consumption. Neuropsychological drugs were more frequently used by health care workers (8%). The transport sector contained the highest proportion of cardiological medication users (12%). Finally, 30-59% of employees reported at least one sickness absence episode. Sickness absence due to locomotor issues was highest in manufacturing (11%) and health care (10%), followed by government (9%) and construction (9%). Significant differences in indices of workers' health were observed between sectors. This information is now being used in the implementation of a sector-oriented health surveillance programme. © The Author 2015.

The verification of the occupational origin of a disease is a forensic medical activity requiring: the confirmation of the existence and of the exact nosographic identification of the disease, as well as the type of work really performed, and the actual exposure to an effective occupational hazard during an adequate time, and finally a reconstruction of the causal relationship based on objective data. Checking the disease is essentially documentary, corroborated by direct survey by medical examination. The assessment of exposure to the occupational hazard must be scrupulous also, not being acceptable the medical history alone: that is, it does require documentary evidence. Finally, the logical process of recognition of causation requires the application of rigorous forensic medical methodology, with references to current scientific knowledge, and the application of legal criteriology from the legal field of law in which you are moving. Indeed, forensic medical methodology is not the same of epidemiological one: probability of occurrence of an event is not a proof, but only a circumstantial element. A forensic medical doctor organizes every evidence and circumstantial evidence in a unique decision-making process, as a result of a logical process, and probabilistic data can be among circumstantial evidence, but they must suit the case in details, in order to reach the so called "logic probability". But this doesn't mean that you have "proven" the occupational origin of a disease. In the "demonstration" of a fact you use the same forensic medical methodology (thus referring to classic criteria: temporality, biological gradient and plausibility, topographical, exclusion, and phenomenal continuity if suitable, too), and also the same general scientific references, nevertheless the law can be different in causality principles admitted (the principles governing the causal link are the same in Criminal Code and Civil law both, but they differ in private insurance), and

Full Text Available This article was inspired by our awareness of an increasing number of voice students and professional singers who specialize in Western art music and who present with symptoms relating to gastro-esophageal reflux disease (GERD. In our attempts to understand this phenomenon, we began questioning the relationship between diaphragmatic-intercostal breathing (DIB and the occurrence of GERD. This study uses two of the methods by which qualitative research can be done, namely literature reviews and case studies. The results of the literature review show that the way in which the lower esophageal sphincter (LES functions during DIB has direct bearing on the possible movement of gastric acids via the esophagus into the pharynx and the larynx. Acknowledging the fact that we are not medical experts, we then used the data from the case studies to suggest how singers might adjust their life styles in order to restrict or prevent occurrences of GERD.

Agricultural workers' health depends on many factors: working conditions, security arrangements, medicine, quality of drugs, the environment, etc. Occupational injuries and diseases are also among the factors that can negatively affect their health. To analyze provisions of the international legislation and scientific literature concerning existence of restrictions on impact of occupational injuries and diseases on agricultural workers' health. International acts, data of international organizations and conclusions of scientists have been examined and used in the study. The article also integrates information from scientific journals and monographs from a medical and legal point of view with scientific methods. This article is based on dialectical, comparative, analytic, synthetic and comprehensive research methods. Impact of occupational injuries and diseases on agricultural workers' health has been studied within the system approach, as well as analysis and synthesis. The level of occupational morbidity, traumatism and above all standard of agricultural workers' health depends on the way of occupational safety organization. Working conditions and safety in agricultural industry and therefore the appropriate standard of health remain unsatisfactory in many countries.

Occupational injuries and diseases are costly for companies and for society as a whole. This study estimates the overall costs of occupational injuries and diseases in Québec, both human and financial, during the period from 2005 to 2007. The human capital method is used to estimate lost productivity. A health indicator (DALY) is used in combination with a value of statistical life (VSL) to estimate, in monetary terms, the pain and suffering costs resulting from occupational injuries. The costs of occupational injuries and diseases occurring in a single year in Québec are estimated at $4.62 billion, on average, for the 2005-2007 period. Of this amount, approximately $1.78 billion is allocated to financial costs and $2.84 billion to human costs. The average cost per case is $38,355. In view of the limitations identified in the study, it can be argued that this is an underestimation of the costs. Result analysis allows the injury/disease descriptors and industries for which the costs are highest to be identified. The results of these estimates are a relevant source of information for helping to determine research directions in OHS and prevention. The methodology used can be replicated for the purposes of estimating the costs of injuries and diseases in other populations. Copyright © 2014 Elsevier Ltd. All rights reserved.

The morbidity of 1557 grandchildren of subjects occupationally exposed to chronic radiation were analyzed. Three groups were singled out. Group 1 consisted of children whose grandfathers were exposed, group 2 of children grandmothers were exposed and group 3 of children whose both grandparent were exposed. Total morbidity level and morbidity structure for 13 classes of diseases and 60 nosological entities was assessed. The study showed that disease incidence in general, structure by disease and individual nosological entities, the share of frequently falling ill children, and health index in the test group corresponded to those in controls. Reliable differences were observed only for respiratory diseases, at the expense of acute respiratory diseases, which were frequent during the second-third years of life in children whose both grandparents were occupationally exposed to radiation [ru

The whole spectrum of disorders of the hematopoietic tissue, eye and skin induced by ionizing radiation covers complex pathologies termed as a postirradiation syndrome, as well as various malignancies. The aim of this work is to present the data on incidence of occupational diseases with ionizing radiation as a causative agent. The work is based on the data compiled from "Occupational Diseases Reporting Forms" for the years 1971-2006 collected in the Central Register of Occupational Diseases. The incidence of certified occupational diseases with ionizing radiation as a causative agent is expressed in absolute numbers and the rate per 100 000 employees. The data comprise information on disease entities, gender, age, exposure duration and the branch of national economy. In total, 599 diseases (0.2% of all occupational diseases) were diagnosed as those induced by ionizong radiation. Annual incidence rates per 100,000 employees fell within the range of 0.0-0.7. Miners formed the major (51.9%) occupational group affected by ionizing radiation. They were followed by health care (34.3%) and construction (6.4%) workers. Cancers made over 50% of pathologies located at 28 sites. These included cancers of lung (59.2%), skin (10.0%) and hematopoietic tissue (8.7%). Almost all (99.35) diseases recorded in the mining industry were cancers. Non-cancer diseases were more frequent in health care workers, among them postradiation cataract occupied the first place. A great deal of reported cancer sites give rise to controversy in terms of the cause-effect association with ionizing radiation exposure and also due to incomplete data on exposure level. Postradiation cancers among health care workers have not been registered over recent years, which means that occupational exposure surveillance carried out for many years proves to be effective. Distant effects of exposure to ionizing radiation, revealed in workers of no longer existing uranium mine, appeared to be a particular problem

Climate change is becoming huge threat to health especially for those from developing countries. Diarrhea as one of the major diseases linked with changing climate. This study has been carried out to assess the relationship between climatic variables, and malaria and to find out the range of non-climatic factors that can confound the relationship of climate change and human health. It is a Retrospective study where data of past ten years relating to climate and disease (diarrhea) variable were analyzed. The study conducted trend analysis based on correlation. The climate related data were obtained from Department of Hydrology and Meteorology. Time Series analysis was also being conducted. The trend of number of yearly cases of diarrhea has been increasing from 1998 to 2001 after which the cases remain constant till 2006.The climate types in Jhapa vary from humid to per-humid based on the moisture index and Mega-thermal based on thermal efficiency. The mean annual temperature is increasing at an average of 0.04 °C/year with maximum temperature increasing faster than the minimum temperature. The annual total rainfall of Jhapa is decreasing at an average rate of -7.1 mm/year. Statistically significant correlation between diarrheal cases occurrence and temperature and rainfall has been observed. However, climate variables were not the significant predictors of diarrheal occurrence. The association among climate variables and diarrheal disease occurrence cannot be neglected which has been showed by this study. Further prospective longitudinal study adjusting influence of non-climatic factors is recommended.

Although occupational accidents and work-related diseases have been of interest for a long time, due to lack of proper recording and notification systems the official numbers of occupational accidents and work-related diseases are missing for many countries. Presently, the demand for effectiveness and an interest in the economic aspects of accidents have increased prevention activities at company and country levels. Occupational accident data of selected countries and of World Health Organization regional divisions together with the global burden of disease were used in estimating global occupational accidents and fatal work-related diseases. The trend of global occupational accidents and work-related diseases is presented at region and country levels. The years 1998, 2001, and 2003 are compared in the case of occupational accidents and the years 2000 and 2002 in the case of work-related diseases. The total number of occupational accidents and fatal work-related diseases has increased, but the fatality rates per 100,000 workers have decreased. There were almost 360,000 fatal occupational accidents in 2003 and almost 2 million fatal work-related diseases in 2002. Every day more than 960,000 workers get hurt because of accidents. Each day 5,330 people die because of work-related diseases. Information on occupational accidents and work-related diseases is needed so that countries may understand better the importance of occupational health and safety at country and company level. Especially companies in developing countries are not familiar with occupational safety and health. Statistical data is essential for accident prevention; it is a starting point for the safety work.

Full Text Available Ebolavirus disease (EVD is a severe contagious disease in humans, and health care workers (HCW are at risk of infection when caring for EVD patients. This paper highlights the epidemiologic profile of EVD and its impact on the health care workforce in Africa. A documentary study was conducted which consisted of a review of available literature regarding the epidemiology of EVD, occupational EVD (OEVD, and work safety issues in Sub-Saharan Africa; the literature findings are enriched by field experiences from the authors. EVD outbreaks have already caused 30,500 cases in humans of whom 12,933 died (as of September 9, 2015, and the number of infected HCW has dramatically increased. All eight HCW infected during the 2014 outbreak in Democratic Republic of the Congo died, whereas during the recent West African EVD epidemic more than 890 HCW were infected, with a case fatality rate of 57%. Occupational exposure to blood and other body fluids due to inadequate use of personal protective equipment and needle stick or sharp injuries are among factors that contribute to the occurrence of OEVD. Prevention of OEVD should be one of the top priorities in EVD outbreak preparedness and management, and research should be conducted to elucidate occupational and other factors that expose HCW to EVD. In addition to regularly training HCW to be adequately prepared to care for patients with EVD, it is critical to strengthen the general health care system and improve occupational safety in medical settings of countries at risk.

In the Workers' Compensation Insurance (WCI) system in Korea, occupational diseases (ODs) are approved through deliberation meetings of the Committee on Occupational Disease Judgment (CODJ) after disease investigations when workers or medical institutions requested the Korea Workers' Compensation and Welfare Service (COMWEL) for medical care benefits. Insufficient data presented by employers or workers or lack of objective evidence may increase the possibility of disapproval. The expertise of accident investigation staff members should be reinforced and employers' and related institutions' obligations to cooperate and submit data should be specified under the law. The deliberation meetings of the CODJ are held separately for musculoskeletal, cerebro-cardiovascular, and medical diseases, and the judgments of ODs are made by the chairperson of COMWEL and six committee members by majority vote by issue. To reinforce the expertise of the members of the CODJ, periodic education and a system to accredit the committee members after appropriate education should be introduced. To fairly and quickly compensate for diseases that occur in workers, the criteria for the recognition of occupational diseases should be continuously amended and the systems for disease investigations and judgments should be continuously improved.

To evaluate the monitoring and early warning functions of the occupational disease reporting system right now in China, and to analyze their influencing factors. An improved audit tool (ODIT) was used to score the monitoring and early warning functions with a total score of 10. The nine indices were completeness of information on the reporting form, coverage of the reporting system, accessibility of criteria or guidelines for diagnosis, education and training for physicians, completeness of the reporting system, statistical methods, investigation of special cases, release of monitoring information, and release of early warning information. According to the evaluation, the occupational disease reporting system in China had a score of 5.5 in monitoring existing occupational diseases with a low score for release of monitoring information; the reporting system had a score of 6.5 in early warning of newly occurring occupational diseases with low scores for education and training for physicians as well as completeness of the reporting system. The occupational disease reporting system in China still does not have full function in monitoring and early warning. It is the education and participation of physicians from general hospitals in the diagnosis and treatment of occupational diseases and suspected occupational diseases that need to be enhanced. In addition, the problem of monitoring the incidence of occupational diseases needs to be solved as soon as possible.

Medical monitoring of workers occupationally exposed to ionizing radiation enables evaluation of their state of health, as well as early detection of general or somatic diseases which are considered as a criterion of unfitness for work, and which may or may not be related to the exposure conditions. A retrospective study is presented of all the cases of workers suspected to be suffering from radiation-related diseases which were referred for specialized study to the Institute of Occupational Medicine (IMT) during 1990-95. The incidence of the diseases and affected tissues is described, as well as the relationship between the time of manifestation and the type of source, the exposure time and the recorded dose levels. Diseases of the haemolymphopoietic system predominated, being observed in individuals exposed to medical radiodiagnostic sources. (author)

Study covered 426 miners aged 40-54 years with previously diagnosed occupational respiratory diseases due to dust (246 patients with chronic occupational obstructive bronchitis, 98 with anthracosilicosis and 82 with chronic dust nonobstructive bronchitis). 315 (73.9%) examinees out of 426 with lung diseases due to dust demonstrated chronic cor pulnmonale. Considering high share of this complication, the authors used Bayes method to create a method to diagnose predisposition towards chronic cor pulmonale in patients with dust lung diseases through respiratory failure, concomitant coronary heart disease and arterial hypertension, blood groups ABO, MN and P, some structural and functional parameters of heart: myocardium weight index, relative wall thickness index and left ventricle sphericity index, average lung artery pressure. Increasing number of analyzed factors that directly influence chronic cor pulmonale development and selecting additional markers help to improve forecasting of the complication.

The population attributable fraction (PAF) is a useful measure for describing the expected change in an outcome if its risk factors are modified. Cohort studies allow researchers to assess the predictive value of the risk factor modification on the incidence of the outcome during a certain follow-up. Estimation of PAF for both mortality and morbidity in cohort studies with censored survival data has been developed in the recent years. So far, however, censoring due to death in the estimation of PAF for morbidity has been ignored, resulting in estimation of a quantity which is not relevant in practice as some people are likely to die during the follow-up. The risk factors related to the disease incidence may also be related to mortality, and modification of these risk factors is likely to delay the occurrence of both events. Thus, censoring due to death and the impact of risk factor modification must be considered when estimating PAF for disease incidence. We consider both and introduce two measures of disease burden: PAF for the incidence of disease during lifetime and PAF for the prevalence of disease in the population at a certain time. We demonstrate how consideration of censoring due to death changes the estimated PAF for disease incidence and its confidence interval. This underlines the importance of choosing a correct PAF measure depending on the outcome of interest and the risk factors of interest to obtain accurate and interpretable results.

European societies are becoming increasingly ethnically diverse. This may have important implications for socio-economic inequalities in health due to the often disadvantaged position of ethnic minority groups in both socio-economic status (SES) and disease, especially cardiovascular disease (CVD). The aim of this study was to determine whether the socio-economic gradient of estimated CVD risk differs between ethnic groups. Using the Healthy Life in an Urban Setting study, we obtained data on SES and CVD risk factors among participants from six ethnic backgrounds residing in Amsterdam. SES was measured using educational level and occupational level. CVD risk was estimated based on the occurrence of CVD risk factors using the Dutch version of the systematic coronary risk evaluation algorithm. Ethnic disparities in socio-economic gradients for estimated CVD risk were determined using the relative index of inequality (RII). Among Dutch-origin men, the RII for estimated CVD risk according to educational level was 6.15% (95% confidence interval [CI] 4.35-7.96%), indicating that those at the bottom of the educational hierarchy had a 6.15% higher estimated CVD risk relative than those at the top. Among Dutch-origin women, the RII was 4.49% (CI 2.45-6.52%). The RII was lower among ethnic minority groups, ranging from 0.83% to 3.13% among men and -0.29% to 5.12% among women, indicating weaker associations among these groups. Results were similar based on occupational level. Ethnic background needs to be considered in associations between SES and disease. The predictive value of SES varies between ethnic groups and may be quite poor for some groups.

Exposures to molds and bacteria (especially actinomycetes) at workplaces are common in garbage workers, but allergic respiratory diseases due to these microorganisms have been described rarely. The aim of our study was a detailed analysis of mold or bacteria-associated occupational respiratory diseases in garbage workers. From 2002 to 2011 four cases of occupational respiratory diseases related to garbage handling were identified in our institute (IPA). Hypersensitivity pneumonitis (HP) was diagnosed in three subjects (cases 1-3, one smoker, two non-smokers), occupational asthma (OA) was diagnosed in one subject (case 4, smoker), but could not be excluded completely in case 2. Cases 1 and 2 worked in composting sites, while cases 3 and 4 worked in packaging recycling plants. Exposure periods were 2-4 years. Molds and actinomycetes were identified as allergens in all cases. Specific IgE antibodies to Aspergillus fumigatus were detected exclusively in case 4. Diagnoses of HP were essentially based on symptoms and the detection of specific IgG serum antibodies to molds and actinomycetes. OA was confirmed by bronchial provocation test with Aspergillus fumigatus in case 4. In conclusion, occupational HP and OA due to molds occur rarely in garbage workers. Technical prevention measures are insufficient and the diagnosis of HP is often inconclusive. Therefore, it is recommended to implement the full repertoire of diagnostic tools including bronchoalveolar lavage and high resolution computed tomography in the baseline examination.

Around the globe, work has a heavy impact on health. To better advise policy makers, we assessed the global burden of disease and injury due to selected occupational hazards. This article presents an overview, and describes the methodology employed in the companion studies. Using the World Health Organization (WHO) Comparative Risk Assessment methodology, we applied relative risk measures to the proportions of the population exposed to selected occupational hazards to estimate attributable fractions, deaths, and disability-adjusted life years (DALYs). Numerous occupational risk factors had to be excluded due to inadequate global data. In 2000, the selected risk factors were responsible worldwide for 37% of back pain, 16% of hearing loss, 13% of chronic obstructive pulmonary disease (COPD), 11% of asthma, 8% of injuries, 9% of lung cancer, and 2% of leukemia. These risks at work caused 850,000 deaths worldwide and resulted in the loss of about 24 million years of healthy life. Needlesticks accounted for about 40% of Hepatitis B and Hepatitis C infections and 4.4% of HIV infections in health care workers. Exposure to occupational hazards accounts for a significant proportion of the global burden of disease and injury, which could be substantially reduced through application of proven risk prevention strategies. 2005 Wiley-Liss, Inc.

Diarrheal diseases continue to pose a severe health threat in regions where sanitation facilities remain marginal and are prone to destruction. With limited efficacy of vaccines, it is important to device alternate methods to determine environmental conditions favorable for diarrheal diseases. Several vibrios (V. cholerae., V. vulnificus, V. parahaemolyticus) have characteristic signatures that are associated with large scale climatic processes. The interactions of vibrios with humans eventually lead to outbreak of diseases. Here, using cholera as one of the signature diarrheal disease, we present a framework coupling social, hydrological and microbiological understanding with satellite remote sensing data to predict environmental conditions associated with outbreak of disease in several regions of sub-Saharan Africa. Hydroclimatic processes, primarily precipitation and temperature are found to be strongly associated with epidemic and episodic outbreak of cholera. We will present an algorithm to classify regions susceptible to risks of outbreak cholera using profile method in five epidemic regions of Mozambique, Central African Republic, Cameroon, South Sudan and Rwanda. Conditions for occurrence of cholera were detectable at least one month in advance. Using spatial land surface temperature (LST) data from satellites along with water accessibility data and population data, the implementation of the algorithm aid in classification of cholera risk regions.

Full Text Available Like most ASEAN countries, Brunei faces an epidemic of non-communicable diseases. To deal with the complexity of NCDs prevention, all perspectives - be it social, familial or occupational – need to be considered. In Brunei Darussalam, occupational health services (OHS offered by its Ministry of Health, among others, provide screening and management of NCDs at various points of service. The OHS does not only issue fitness to work certificates, but is a significant partner in co-managing patients’ health conditions, with the advantage of further management at the workplace. Holistic approach of NCD management in the occupational setting is strengthened with both employer and employee education and participation, targeting several approaches including risk management and advocating healthy lifestyles as part of a healthy workplace programme.

The iron foundries are still well represented in the area of Brescia and, despite having been involved in a major technological developments, have still risks to the health of workers. In order to verify the state of the art and effectiveness of prevention measures implemented by various companies, in recent years have carried out numerous inspections, environmental monitoring and biological. Furthermore, there were in the regional information system diseases reported and/or by the reported health. In particular it is shown that, in addition to chemical and physical risk factors, although in a much reduced compared to the 80s, are still present in our workplace pollutants (PAHs, silica, metal fumes, formaldehyde) at the base of classification of iron foundries in group 1, carcinogenic to humans, IARC, 1987 e 2012.

There is insufficient evidence to support use of occupational therapy interventions for patients with Parkinson's disease. We aimed to assess the efficacy of occupational therapy in improving daily activities of patients with Parkinson's disease. We did a multicentre, assessor-masked, randomised controlled clinical trial in ten hospitals in nine Dutch regional networks of specialised health-care professionals (ParkinsonNet), with assessment at 3 months and 6 months. Patients with Parkinson's disease with self-reported difficulties in daily activities were included, along with their primary caregivers. Patients were randomly assigned (2:1) to the intervention or control group by a computer-generated minimisation algorithm. The intervention consisted of 10 weeks of home-based occupational therapy according to national practice guidelines; control individuals received usual care with no occupational therapy. The primary outcome was self-perceived performance in daily activities at 3 months, assessed with the Canadian Occupational Performance Measure (score 1-10). Data were analysed using linear mixed models for repeated measures (intention-to-treat principle). Assessors monitored safety by asking patients about any unusual health events during the preceding 3 months. This trial is registered with ClinicalTrials.gov, NCT01336127. Between April 14, 2011, and Nov 2, 2012, 191 patients were randomly assigned to the intervention group (n=124) or the control group (n=67). 117 (94%) of 124 patients in the intervention group and 63 (94%) of 67 in the control group had a participating caregiver. At baseline, the median score on the Canadian Occupational Performance Measure was 4·3 (IQR 3·5-5·0) in the intervention group and 4·4 (3·8-5·0) in the control group. At 3 months, these scores were 5·8 (5·0-6·4) and 4·6 (4·6-6·6), respectively. The adjusted mean difference in score between groups at 3 months was in favour of the intervention group (1·2; 95% CI 0·8-1·6
Full Text Available The relation between disease risk and a point source of pollution is usually investigated using distance from the source as a proxy of exposure. The analysis may be based on case-control data or on aggregated data. The definition of the function relating risk of disease and distance is critical, both in a classical and in a Bayesian framework, because the likelihood is usually very flat, even with large amounts of data. In this paper we investigate how the specification of the function relating risk of disease with distance from the source and of the prior distributions on the parameters of the function affects the results when case-control data and Bayesian methods are used. We consider different popular parametric models for the risk distance function in a Bayesian approach, comparing estimates with those derived by maximum likelihood. As an example we have analyzed the relationship between a putative source of environmental pollution (an asbestos cement plant and the occurrence of pleural malignant mesothelioma in the area of Casale Monferrato (Italy in 1987-1993. Risk of pleural malignant mesothelioma turns out to be strongly related to distance from the asbestos cement plant. However, as the models appeared to be sensitive to modeling choices, we suggest that any analysis of disease risk around a putative source should be integrated with a careful sensitivity analysis and possibly with prior knowledge. The choice of prior distribution is extremely important and should be based on epidemiological considerations.

The influence of mental illness early in life on the subsequent risk of Parkinson disease (PD) and its clinical picture remain obscure. This study investigated the effects of psychiatric diseases on a subsequent PD diagnosis. We used the Longitudinal Health Insurance Database 2000 of Taiwan to identify 73,597 patients who visited ambulatory care centers or were hospitalized with a first-time diagnosis of anxiety, affective disorders, or schizophrenia between 2001 and 2003 as the study cohort. We also randomly selected 220,791 enrollees matched with the study cohort for comparison. Each patient was individually tracked for 6 years to identify a subsequent PD diagnosis. Stratified Cox proportional hazard regressions were performed for the analysis. The incidence rate of PD per 1000 person-years was 4.91 (95% confidence interval [CI], 4.71-5.12) and 1.63 (95% CI, 1.56-1.70) for the psychiatric and comparison groups, respectively. Patients with psychiatric illnesses were more vulnerable to developing PD than nonpsychiatric individuals, exhibiting a 2.38-fold increased risk (95% CI, 2.23-2.53) after other covariates were considered. Furthermore, patients with schizophrenia exhibited the highest risk for developing PD. We suggest effective monitoring of patients with psychiatric disturbances for potential long-term neurodegenerative diseases. Copyright © 2014 Elsevier Inc. All rights reserved.

The author describes the discovery of a cluster of cases of interstitial lung disease among employees of a textile manufacturing plant and the difficulties he and his university-hospital occupational medicine team encountered in attempting to identify the cause of the disease. At first accepted in a consultant capacity by the plant's management, the team met increasing resistance to its efforts as it uncovered evidence of a work-related cause of the disease and attempted ientists to communicate findings important to the health of the public, and the physician's overarching professional responsibility to his or her patients.

Military personnel deployed to Iraq and Afghanistan, from 2004 to the present, has served in a setting of unique environmental conditions. Among these are exposures to burning trash in open air "burn pits" lit on fire with jet fuel JP-8. Depending on trash burned--water bottles, styrofoam trays, medical waste, unexploded munitions, and computers--toxins may be released such as dioxins and n-hexane and benzene. Particulate matter air pollution culminates from these fires and fumes. Additional environmental exposures entail sandstorms (Haboob, Shamal, and Sharqi) which differ in direction and relationship to rain. These wars saw the first use of improvised explosive devices (roadside phosphate bombs),as well as vehicle improvised explosive devices (car bombs), which not only potentially aerosolize metals, but also create shock waves to induce lung injury via blast overpressure. Conventional mortar rounds are also used by Al Qaeda in both Iraq and Afghanistan. Outdoor aeroallergens from date palm trees are prevalent in southern Iraq by the Tigris and Euphrates rivers, while indoor aeroallergen aspergillus predominates during the rainy season. High altitude lung disease may also compound the problem, particularly in Kandahar, Afghanistan. Clinically, soldiers may present with new-onset asthma or fixed airway obstruction. Some have constrictive bronchiolitis and vascular remodeling on open lung biopsy - despite having normal spirometry and chest xrays and CT scans of the chest. Others have been found to have titanium and other metals in the lung (rare in nature). Still others have fulminant biopsy-proven sarcoidiosis. We found DNA probe-positive Mycobacterium Avium Complex in lung from a soldier who had pneumonia, while serving near stagnant water and camels and goats outside Abu Gharib. This review highlights potential exposures, clinical syndromes, and the Denver Working Group recommendations on post-deployment health.

Description was made as to the present condition of occurrence of hypothyroidism after treatment of Basedow's disease with 131 I. It was showed that hypothyroidism was not necessarily based on numerical over-dose of 131 I, there were early stage hypothyroidism due to 131 I sensitivity of an individual and delayed hypothyroidism due to irreversible and progressive disorder of the thyroid gland, and examination of inflammatory findings before treatment and reduction of first administered dose of 131 I were effective in prevention of early stage hypothyroidism. At present, the origin of delayed hypothyroidism is not clarified and thus there is not adequate prevention method. It was suggested that it was duty of the person in charge of treatment to observe and guide treated case by careful remote-investigation and to continue efforts in prevention of hypothyroidism hereafter.

A large randomized clinical trial (the Occupational Therapy in Parkinson's Disease [OTiP] study) recently demonstrated that home-based occupational therapy improves perceived performance in daily activities of people with Parkinson's disease (PD). The aim of the current study was to evaluate the cost-effectiveness of this intervention. We performed an economic evaluation over a 6-month period for both arms of the OTiP study. Participants were 191 community-dwelling PD patients and 180 primary caregivers. The intervention group (n = 124 patients) received 10 weeks of home-based occupational therapy; the control group (n = 67 patients) received usual care (no occupational therapy). Costs were assessed from a societal perspective including healthcare use, absence from work, informal care, and intervention costs. Health utilities were evaluated using EuroQol-5d. We estimated cost differences and cost utility using linear mixed models and presented the net monetary benefit at different values for willingness to pay per quality-adjusted life-year gained. In our primary analysis, we excluded informal care hours because of substantial missing data for this item. The estimated mean total costs for the intervention group compared with controls were €125 lower for patients, €29 lower for caregivers, and €122 higher for patient-caregiver pairs (differences not significant). At a value of €40,000 per quality-adjusted life-year gained (reported threshold for PD), the net monetary benefit of the intervention per patient was €305 (P = 0.74), per caregiver €866 (P = 0.01) and per patient-caregiver pair €845 (P = 0.24). In conclusion, occupational therapy did not significantly impact on total costs compared with usual care. Positive cost-effectiveness of the intervention was only significant for caregivers. © 2015 International Parkinson and Movement Disorder Society.

Full Text Available Abstract Background- The aim of the study was to develop quality indicators that can be used for quality assessment of registries of occupational diseases in relation to preventive policy on a national level. The research questions were: 1. Which indicators determine the quality of national registries of occupational diseases with respect to their ability to provide appropriate information for preventive policy? 2. What are the criteria that can distinguish low quality from high quality? Methods- First, we performed a literature search to assess which output of registries can be considered appropriate for preventive policy and to develop a set of preliminary indicators and criteria. Second, final indicators and criteria were assessed and their content validity was tested in a Delphi study, for which experts from the 25 EU Member States were invited. Results- The literature search revealed two different types of information output to be appropriate for preventive policy: monitor and alert information. For the evaluation of the quality of the monitor and alert function we developed ten indicators and criteria. Sixteen of the twenty-five experts responded in the first round of the Delphi study, and eleven in the second round. Based on their comments, we assessed the final nine indicators: the completeness of the notification form, coverage of registration, guidelines or criteria for notification, education and training of reporting physicians, completeness of registration, statistical methods used, investigation of special cases, presentation of monitor information, and presentation of alert information. Except for the indicator "coverage of registration" for the alert function, all the indicators met the preset requirements of content validity. Conclusion- We have developed quality indicators and criteria to evaluate registries for occupational diseases on the ability to provide appropriate information for preventive policy on a national level

Occupational physical activity (OPA) is an occupational exposure that impacts worker health. OPA is amenable to measurement and modification through the hierarchy of controls. Occupational exposure scientists have roles in addressing inadequate physical activity, as well as excessive or harmful physical activity. Occupational health researchers can contribute to the development of novel OPA exposure assessment techniques and to epidemiologic studies examining the health impacts of physical activity at work. Occupational health practitioners stand to benefit from understanding the strengths and limitations of physical activity measurement approaches, such as accelerometers in smartphones, which are already ubiquitous in many workplaces and in some worksite health programs. This comprehensive review of the literature provides an overview of physical activity monitoring for occupational exposure scientists. This article summarizes data on the public health implications of physical activity at work, highlighting complex relationships with common chronic diseases. This article includes descriptions of several techniques that have been used to measure physical activity at work and elsewhere, focusing in detail on pedometers, accelerometers, and Global Positioning System technology. Additional subjective and objective measurement strategies are described as well.

As industrial use of radiation sources grew rapidly from the 70th on, and so did the workforce handing the sources, it is evident, that the amount of occupational exposed persons who will now come to an age where (spontaneous) cancer diseases become manifest is also growing. There will be a certain number of people who will declare this disease being caused by the occupational exposure. Investigation and decision in such cases have to be performed in short time and will be enhanced by a good experience from former cases. In Germany the workman's compensation institutions (Industrial Injury Insurance Institutes (IIII) Berufsgenossenschaften) are responsible for all questions of medical care, rehabilitation and compensation of occupational accidents and diseases. They decided to provide a registry for all cases which came to investigation. Since 1980 the institute of radiation protection which was founded in the late 70th by two of this IIII (Berufsgenossenschaft der Feinmechanik und Elektrotechnik and Berufsgenossenschaft der Chemischen Industrie) is performing the data-collection. The quality of the data depends of course on the details which are reported to the Institute in each case and on the criteria, when at all a case should be reported to the registry. Unfortunately it was not possible to edit general reporting criteria. Each Industrial Injury Insurance Institute in Germany (there are 36 of them) decides by itself about the reporting criteria. Of course this leads to a loss of information as is shown later. (author)

The risk of psychological disorders influencing the health of workers increases in accordance with growing requirements on employees across various professions. This study aimed to compare approaches to the burnout syndrome in European countries. A questionnaire focusing on stress-related occupational diseases was distributed to national experts of 28 European Union countries. A total of 23 countries responded. In 9 countries (Denmark, Estonia, France, Hungary, Latvia, Netherlands, Portugal, Slovakia and Sweden) burnout syndrome may be acknowledged as an occupational disease. Latvia has burnout syndrome explicitly included on the List of ODs. Compensation for burnout syndrome has been awarded in Denmark, France, Latvia, Portugal and Sweden.Only in 39% of the countries a possibility to acknowledge burnout syndrome as an occupational disease exists, with most of compensated cases only occurring in recent years. New systems to collect data on suspected cases have been developed reflecting the growing recognition of the impact of the psychosocial work environment. In agreement with the EU legislation, all EU countries in the study have an action plan to prevent stress at the workplace.

Physiotherapists are exposed to diverse occupational demands. Until now, little has been known about the interaction between occupational stress and the job satisfaction of physiotherapists. This paper aims to examine their work-related stress and job satisfaction. It will analyse accidents at work and occupational diseases of physiotherapists along with work-related physical and psychosocial stress and job satisfaction. We analysed routine data of the German Institute for Statutory Accident Insurance and Prevention in the Health and Welfare Services (BGW) on accidents at work and occurring en route to/from work as well as occupational diseases of physiotherapists. Work-related stress and job satisfaction were examined in a cross-sectional survey using a standard questionnaire to be completed by subjects themselves. Between 2007 and 2011, 1,229 cases of occupational disease were reported to the BGW. The majority of reports involved skin diseases (73%). Stumbles and falls were the most frequent causes of accidents at work (42.9%). Eighty-five physiotherapists all over Germany took part in the survey. They experience high quantitative demands at work. The main physical demands consist of a torso posture between 45° and 90° and high hand activity. Of the 85 subjects, 51% suffer from complaints of the musculoskeletal system in the neck and thoracic spine area and 24% have skin diseases. Most physiotherapists (88%) are satisfied with their work overall. This is aided by a high degree of influence on their work and breaks, by practical application of skills and expert knowledge, high regard for their profession, varied work and a good atmosphere at work. Reservations tend to be about statutory regulations and the social benefits provided by the German healthcare system. Overall, despite high demands and stress relating to the adequacy of resources, the majority of physiotherapists surveyed seem to be satisfied with their job. The main focus of action to promote the

Objective: To discuss the incidence and clinical predictors of radial artery spasm occurred in performing transradial coronary intervention for coronary heart disease. Methods: A total of 1020 patients, who underwent transradial coronary procedures for coronary heart disease during the period of May 2007 Jan 2010 in authors' hospital, were enrolled in this study. All clinical information and medication were recorded in detail. Arteriography via radial artery was performed in all patients. The diameter of the radial artery as well as the arterial anatomy, including arterial variations, were determined and observed, which was follow by coronary angiography or percutaneous coronary intervention. Multivariate Logistic regression analysis was adopted to evaluate the variables, such as clinical parameters, angiographic characteristics of the radial artery and procedure-related factors, in predicting the occurrence of radial artery spasm. Results: Radial artery spasm occurred in 209 (20.5%) patients. Multivariate Logistic regression analysis showed that the following eight factors were independently associated with the occurrence of radial artery spasm. These factors were as follows: female gender (OR=2.8, 95% CI 2.5-5.8; P=0.001), age (OR=0.68, 95% CI 0.60-0.92; P=0.003), smoking (OR=2.3, 95% CI 1.8-4.1; P=0.026), moderate-to-severe pain of forearm during radial artery cannulation (OR=3.0, 95% CI 2.3-4.8; P=0.006), radial artery anatomical abnormalities (OR=4.7, 95% CI 3.6-7.2; P=0.002), the ratio of radial artery diameter to patient's height (RAH) (OR=5.2, 95% CI 3.7-8.1; P=0.012), the ratio of radial artery diameter to outer diameter of the sheath (RAOD) (OR=5.8, 95% CI 4.2-6.9; P=0.006) and the number of catheter exchange (OR=2.3, 95% CI 1.4-4.3; P=0.038). Conclusion: Radial artery spasm occurred in performing transradial coronary intervention for coronary heart disease is frequently seen in clinical practice. Female gender, younger age, smoking, forearm pain during

The aim of this study was to evaluate the effectiveness of patient education in occupational skin diseases (OSD) regarding changes of the disease-specific knowledge. One hundred and five patients participated in structured patient education as part of an interdisciplinary outpatient prevention measure. In a prospective one-group pre-post-design, the disease-specific knowledge was assessed with the validated "Occupational Skin Diseases Knowledge Questionnaire" (OSD-KQ) before (T0) and after the intervention (T1). A subcohort (n = 68) was examined 2-3 months later (T2). The mean OSD-KQ score significantly improved from 38.5 (59.2% of correct answers, T0) to 55.6 (85.5% of correct answers, T1). A pronounced heterogeneity was observed among the participants regarding the pre-interventional knowledge (10.8-84.6% of correct answers, T0) and the individual knowledge gain. Patients who worked in health-related occupations scored significantly higher. Age and sex did not influence the knowledge. In a subcohort, a significantly improved disease-specific knowledge of 52.3 (80.5% of correct answers) could still be found 2-3 months after the intervention (T2). Structured patient education significantly improves the disease-specific knowledge in patients with OSD. The study indicates not only positive short- but also sustainable long-term effects on the knowledge gain. The OSD-KQ can serve as a tool to evaluate and improve patient education. Health educators need to be aware of the heterogeneity regarding the participants' knowledge and take this into account during educational practice. Additional counseling may be necessary to meet the individual learners' needs.

The Comparative Risk Assessment (CRA) project of the World Health Organization (WHO) assessed worldwide mortality and morbidity in the year 2000 resulting from exposures to selected occupational hazards. This article summarizes findings of the WHO CRA project, presents the estimates of the International Labor Organization (ILO) for total deaths due to workplace risks, and calls for action. Global burden estimates and counts of deaths assist ministers and other decision and policy makers to make informed decisions and to take action regarding risk reduction. The WHO CRA methodology combined the proportions of the population exposed to five occupational hazards (excluding numerous risks due to inadequate global data) with relative risk measures to estimate attributable fractions of the selected health outcomes for both morbidity and mortality. ILO estimates of total numbers of global work-related injury deaths apply national fatality rates to employment data for the particular country; for disease deaths ILO uses an attributable risk approach. In 2000, the selected occupational risk factors were responsible worldwide for 37% of back pain, 16% of hearing loss, 13% of chronic obstructive pulmonary disease (COPD), 11% of asthma, 8% of injuries, 9% of lung cancer and 2% of leukemia, and about 100% of pneumoconioses and mesothelioma. These selected risks at work resulted in the loss of about 24 million years of healthy life and caused 850,000 deaths worldwide, about 40% of the ILO estimate of 2.2 million total deaths. These global and regional analyses have identified areas where specific preventive actions are required.

The Work Accidents and Occupational Diseases Act exists in Chile since 1968. It uses a single model for the understanding and management of both somatic diseases like silicosis and psychiatric disorders. During the last decade in Chile, the consultation rates due to psychiatric conditions of probable labor origin has rose over 1,000%, a factor that underscored the deficiencies of this model. The aim of this paper is to analyze the consequences of the application of this act in the psychiatric field for almost 50 years after its promulgation. This article contains an historical overview and an epistemological debate based on the authors experience dealing with clinical and administrative work both in occupational psychiatry departments and in regulatory entities. The development of occupational mental health in Chile is examined as part of an historical process that initially did not consider the relationship between work and mental suffering as relevant. The application of a single causality model in psychiatry, as well as the effects of building a psychiatric nosology upon legal rather than medical criteria is contested.

Health problems caused by long working hours and work stress have gained growing concerns in Japan, Korea, and Taiwan. In all the three countries, cardiovascular, cerebrovascular, and mental disorders attributed to heavy workloads or stressful work events are considered compensable occupational diseases by workers' compensation systems. This study compared the trends of such cases and correlated the trends with changes in working hours during the period from 1980 to 2010. Data on occupational diseases were obtained from official statistics of the workers' compensation systems. Information on working hours was obtained from official statistics and national surveys of employees. While occupational cardiovascular, cerebrovascular, and mental disorders attributed to work stress were increasingly compensated in all the three countries, the averaged working hours and the percentage of employees with long working hours had been in decline discordantly. Findings of this study suggested that reducing working hours alone is unlikely to reduce the problems of work stress. There is an urgent need to monitor and regulate a wider range of psychosocial work hazards. Especially, precarious employment and its associated health risks should be targeted for effective prevention of stress-related health problems in the workplace.

Full Text Available The article presents the analysis of factors that may influence the attitudes of rural population with occupational diseases to medical service. The analysis is based on the results of the survey that has been conducted in Saratov region in 2013-2014. Ten experts, doctors involved in treating rural population with occupational diseases in Saratov region, formed the sample.It was revealed that refusal from pre-arranged treatment and hospitalization as well as execution of documents on disability is often determined by financial factor, i.e. unwillingness of rural population to lose their job, the only source of income. According to the experts the main factors that may influence the incidence of in- and out-patient visits in rural regions are low accessibility to medical institutions due to isolated location of many rural territories, insufficiency of professional staff able to cope with occupational pathologies in central regional hospitals, lack of medical equipment and facilities. The factors preventing health-saving behavior are as follows: life style and educational level.

There has been an increase in the incidence of occupational asthma along with better understanding of its pathophysiologic mechanisms and etiologic factors. There are no reports of patients with asthma and rhinitis to Passiflora alata (passion flower) and Rhamnus purshiana (cascara sagrada). We describe two substances of plant origin as causal agents of occupational allergic respiratory diseases in a patient who worked in a pharmacy devoted to the manual preparation of products. Skin testing and Western blot confirmed the sensitization of the patient to these plant extracts in vivo and in vitro, respectively. Bronchial challenge confirmed the cause-effect relationship between the allergen exposure and the diseases. We conclude that Passiflora and cascara sagrada are two new etiologic agents of IgE-mediated occupational asthma and rhinitis. The present study also serves to alert physicians to the risks associated with work in pharmacies devoted to manual preparation of plant extracts, emphasizing the importance of the use of protective measures in these environments.

There are 56 nations and 1.37 billion peoples (2010, November). In 2010, GDP was 40120.2 billion Yuan, and per capita GDP was 3,600 dollars. Employment population nearly reached 780 million peoples, including a total of 226 million migrant workers. At present, China is in the rapid development period of industrialization, urbanization and globalization, and workers face the traditional and novel dual occupational hazards. Also, prevention and control of occupational disease faces severe situations and challenges.
Full Text Available Root rots are a constraint for staple food crops and a long-lasting food security problem worldwide. In common beans, yield losses originating from root damage are frequently attributed to dry root rot, a disease caused by the Fusarium solani species complex. The aim of this study was to model the current potential distribution of common bean dry root rot on a global scale and to project changes based on future expectations of climate change. Our approach used a spatial proxy of the field disease occurrence, instead of solely the pathogen distribution. We modeled the pathogen environmental requirements in locations where in-situ inoculum density seems ideal for disease manifestation. A dataset of 2,311 soil samples from commercial farms assessed from 2002 to 2015 allowed us to evaluate the environmental conditions associated with the pathogen's optimum inoculum density for disease occurrence, using a lower threshold as a spatial proxy. We encompassed not only the optimal conditions for disease occurrence but also the optimal pathogen's density required for host infection. An intermediate inoculum density of the pathogen was the best disease proxy, suggesting density-dependent mechanisms on host infection. We found a strong convergence on the environmental requirements of both the host and the disease development in tropical areas, mostly in Brazil, Central America, and African countries. Precipitation and temperature variables were important for explaining the disease occurrence (from 17.63% to 43.84%. Climate change will probably move the disease toward cooler regions, which in Brazil are more representative of small-scale farming, although an overall shrink in total area (from 48% to 49% in 2050 and 26% to 41% in 2070 was also predicted. Understanding pathogen distribution and disease risks in an evolutionary context will therefore support breeding for resistance programs and strategies for dry root rot management in common beans.

A dataset of 2,311 soil samples from commercial farms assessed from 2002 to 2015 allowed us to evaluate the environmental conditions associated with the pathogen’s optimum inoculum density for disease occurrence, using a lower threshold as a spatial proxy. We encompassed not only the optimal conditions for disease occurrence but also the optimal pathogen’s density required for host infection. An intermediate inoculum density of the pathogen was the best disease proxy, suggesting density-dependent mechanisms on host infection. We found a strong convergence on the environmental requirements of both the host and the disease development in tropical areas, mostly in Brazil, Central America, and African countries. Precipitation and temperature variables were important for explaining the disease occurrence (from 17.63% to 43.84%). Climate change will probably move the disease toward cooler regions, which in Brazil are more representative of small-scale farming, although an overall shrink in total area (from 48% to 49% in 2050 and 26% to 41% in 2070) was also predicted. Understanding pathogen distribution and disease risks in an evolutionary context will therefore support breeding for resistance programs and strategies for dry root rot management in common beans.

Polycystic kidney disease (PKD) is an inherited autosomal disorder in cats, mostly diagnosed in Persian cats. Renal cysts can be diagnosed by ultrasound, but cats must be at least 16 weeks old. The goals of this study were to assess the occurrence of PKD in Serbia using a randomly selected group of Persian cats, to compare the diagnostic efficacy of ultrasound and genetic tests, and to measure haematological and selected biochemical parameters. We examined 70 cats of Persian breed, between 4 months and 8 years of age. Complete blood count and selected biochemical parameters were measured, renal ultrasound was performed. Swabs of the oral cavity were obtained for genetic testing. Percentage of PKD positive cats identified by genetic testing was 48.6%, whilst only 18.6% were detected through ultrasound. Animals that were polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) positive and ultrasound negative ranged from 4 months to 3.5 years. All haematological and biochemical parameters were within the the normal range values in all examined cats. Genetic methods proved to be the most effective for reliable and early diagnosis of PKD in Persian cats. DNA analysis can be used right after birth, and excludes the need for other diagnostic procedures, such as ultrasound.

Ebolavirus disease (EVD) is a severe contagious disease in humans, and health care workers (HCW) are at risk of infection when caring for EVD patients. This paper highlights the epidemiologic profile of EVD and its impact on the health care workforce in Africa. A documentary study was conducted which consisted of a review of available literature regarding the epidemiology of EVD, occupational EVD (OEVD), and work safety issues in Sub-Saharan Africa; the literature findings are enriched by field experiences from the authors. EVD outbreaks have already caused 30,500 cases in humans of whom 12,933 died (as of September 9, 2015), and the number of infected HCW has dramatically increased. All eight HCW infected during the 2014 outbreak in Democratic Republic of the Congo died, whereas during the recent West African EVD epidemic more than 890 HCW were infected, with a case fatality rate of 57%. Occupational exposure to blood and other body fluids due to inadequate use of personal protective equipment and needle stick or sharp injuries are among factors that contribute to the occurrence of OEVD. Prevention of OEVD should be one of the top priorities in EVD outbreak preparedness and management, and research should be conducted to elucidate occupational and other factors that expose HCW to EVD. In addition to regularly training HCW to be adequately prepared to care for patients with EVD, it is critical to strengthen the general health care system and improve occupational safety in medical settings of countries at risk.

Fungal components can cause allergic symptoms either through inhalation, ingestion or contact. Allergic disease from occupational exposure to Boletus edulis (BE) has only seldom been reported. Report on a female worker who developed respiratory and skin symptoms from occupational exposure to BE in selecting and packing dried mushrooms. She never had symptoms after eating mushrooms. An environmental study was performed by personal air samplings and settled dust collection. The RAST-inhibition procedure was used to detect BE allergen potency in collected dust. The subject underwent clinical evaluation, spirometry, skin prick-tests, RAST methacoline and specific inhalation challenge with BE extract. A follow-up study was made 2, 4 and 8 months after the first evaluation and after cessation of exposure. BE allergens were found in the settled dust. Clinical examination showed eczema on the face and hands. The worker had hyper-eosinophilia, bronchial hyper-responsiveness to methacoline, no allergy to common inhalants and foods, positive prick-test and RAST for BE. The specific inhalation challenge induced broncho-constriction. At follow-up we observed a progressive clinical and functional improvement. Our data show that BE can induce cutaneous and respiratory symptoms from occupational exposure to dried mushroom dusts. The pathogenesis is an IgE-allergy. Our patient had no symptoms from ingestion, which supports the hypothesis that respiratory allergy is due to mushroom antigens that differ from those involved in food-related allergic reactions.
Full Text Available Whereas positron emission tomography (PET with the antagonist ligand [18F]fallypride reveals the composite of dopamine D2 and D3 receptors in brain, treatment of Parkinson's disease (PD patients with the D3-prefering agonist pramipexole should result in preferential occupancy in the nucleus accumbens, where the D3-subtype is most abundant. To test this prediction we obtained pairs of [18F]fallypride PET recordings in a group of nine PD patients, first in a condition of treatment as usual with pramipexole (ON-Sifrol; 3 × 0.7 mg p.d., and again at a later date, after withholding pramipexole 48–72 h (OFF-Sifrol; in that condition the serum pramipexole concentration had declined by 90% and prolactin levels had increased four-fold, in conjunction with a small but significant worsening of PD motor symptoms. Exploratory comparison with historical control material showed 14% higher dopamine D2/3 availability in the more-affected putamen of patients OFF medication. On-Sifrol there was significant (p ˂ 0.01 occupancy at [18F]fallypride binding sites in globus pallidus (8% thalamus (9% and substantia nigra (19%, as well as marginally significant occupancy in frontal and temporal cortex of patients. Contrary to expectation, comparison of ON- and OFF-Sifrol results did not reveal any discernible occupancy in nucleus accumbens, or elsewhere in the extended striatum; present methods should be sensitive to a 10% change in dopamine D2/3 receptor availability in striatum; the significant findings elsewhere in the basal ganglia and in cerebral cortex are consistent with a predominance of D3 receptors in those structures, especially in substantia nigra, and imply that therapeutic effects of pramipexole may be obtained at sites outside the extended striatum.

The aim of preventive follow-up examinations of former employees of the concern Czechoslovak Uranium Mines is to determine possible health damage of chronically exposed workers in an area that can become manifest even following a long time after leaving the high-risk working environment. In a group of 1,139 persons that had undergone preventive follow-up examinations in the years 1977 to 1980 there were 63 cases of newly detected affections that were reported as occupational diseases, and other serious affections. The system of preventive follow-up examinations represents a significant contribution to the improvement of health care of the workers. (author)

To determine whether previous health experiences affect the prevalence of occupational lung disease in a semirural Botswanan community where there is a long history of labour recruitment to South African mines. A cross sectional prevalence study of 304 former miners examined according to a protocol including a questionnaire, chest radiograph, spirometry, and medical examination. Overall mean age was 56.7 (range 28-93) years, mean duration of service 15.5 (range 2-42) years. 26.6% had a history of tuberculosis. 23.3% had experienced a disabling occupational injury. Overall prevalence of pnemoconiosis (> 1/0 profusion, by the International Labour Organisation classification) was 26.6%-31.0%, and 6.8% had progressive massive fibrosis (PMF). Many were entitled to compensation under South African law. Both radiograph readers detected time response relations between pneumoconiosis and PMF among the 234 underground gold miners. PMF could result from Botswana have a high prevalence of previously unrecognised pneumoconiosis, indicative of high previous exposures to fibrogenic respirable dust. Their pneumoconiosis went unrecognised because they had no access to surveillance after employment. Inadequate radiographic surveillance or failure to act on results when employed or when leaving employment at the mines could have contributed to under recognition. Community based studies of former miners are essential to fully evaluate the effects of mining exposures. Our findings indicate a failure of established measures to prevent or identify pneumoconiosis while these miners were in employment and show that few of the social costs of occupational lung diseases are borne by mining companies through the compensation system.

Research indicates occupational injuries and diseases are not evenly distributed among workers. We investigated the distribution and characteristics of compensated occupational injuries and diseases requiring medical care in the Finnish farming population. The study population consisted of 93,564 Finnish farmers, spouses, and salaried family members who were covered by the mandatory workers' compensation insurance in 2002. This population had a total of 133,207 occupational injuries and 9,148 occupational diseases over a 26-year period (1982-2008). Clustering of claims was observed. Nearly half (47.1%) of the population had no compensated claims while 52.9% had at least one; 50.9% of farmers had one or more injuries and 8.1% had one or more diseases. Ten percent of the population had half of injury cases, and 3% of the population had half of occupational disease cases. Claims frequently involved work tasks related to animal husbandry and repair and maintenance of farm machinery. Injury and disease characteristics (work activity, cause, ICD-10 code) differed between individuals with high and low personal claim rate. Injuries and diseases of the musculoskeletal system had a tendency to reoccur among those with high claim rate. These outcomes were often related to strenuous working motions and postures in labor-intensive animal husbandry. Analyses of longitudinal insurance data contributes to better understanding of the long-term risk of occupational injury and disease among farmers. We suggest focusing on recurrent health outcomes and their causes among high risk populations could help design more effective interventions in agriculture and other industries.

The aim of this retrospective cohort study was to evaluate the incidence of and risk factors for compensated occupational injuries and diseases in agriculture. The study population consisted of 78,679 Finnish farmers, spouses, and salaried family members covered by mandatory workers' compensation insurance. This population had a total of 24,424 occupational injuries and 1684 diseases from 2000 to 2004. In the 5-year period, 20.2% of the population had (one or more) injuries and 2.0% had occupational diseases. Multiple claims were common particularly among livestock producers. Using Poisson regression analyses, we identified several personal and farm-related risk factors, with relative risk estimates ranging from 1.07 to 3.08 for injuries and from 1.45 to 3.01 for diseases. Cattle-intensive geographic regions, occupational health service membership, large farm size, and farming alone were identified as risk factors for both outcomes. Further, male gender, higher number of insurance years, and residing on the farm were among risk factors for injury. These risk factors identified from a large longitudinal data set can be considered for developing and targeting interventions for farmers at highest risk of occupational injury and disease.

Objective: To investigate the incidence of occupational diseases in a province of China during the period of "Twelfth Five-Year Plan" , and to analyze the features of disease spectrum, the characteristics of regional and industrial distribution, and incidence trend. Methods: Data (2011-2015) were collected from the Information System of Occupational Diseases and Occupational Health to analyze the reported cases of occupational diseases during the period of "Twelfth Five-Year Plan". A statistical analysis was performed to identify the characteristics of the disease distribution in terms of sex, age, working years, enterprise type, enterprise scale, and region, as well as the incidence trend. Results: The overall incidence of occupational diseases in this province fluctuated and decreased gradually. There were a total of 5036 new cases of occupational diseases during the period of "Twelfth Five-Year Plan" ; 89.45% of them were male, and 69.78% of them were aged 40-69 years; the most frequently seen occupational diseases were pneumoconiosis (72.48%) and ear, nose, throat, and oral diseases (7.23%). Most cases of pneumoconiosis occurred after 5-10 years of exposure, and other occupational diseases usually developed within 10 years of exposure. New cases of occupational diseases were often seen in small and micro enterprises, as well as Wuxi, Suzhou, and Yancheng. Conclusion: During the period of "Twelfth Five-Year Plan" , the incidence of occupational diseases in this province decreased gradually, indicating improved control of occupational diseases, but we still need to pay attention to the high-risk population (male, aged over 40 years) , as well as the prevention of occupational noise-induced hearing loss, and to strengthen the supervision of small and micro enterprises.

Full Text Available INTRODUCTION: In 2010, to reduce the occurrence of serious pneumococcal disease, the Ministry of Health in Brazil incorporated the 10-valent pneumococcal vaccine in the immunization schedule of children younger than two years of age. The objective of this study was to evaluate the impact of vaccination on the incidence of infectious respiratory diseases in infants before and after the introduction of the 10-valent pneumococcal vaccine. METHODS: This cross-sectional study involved primary care and hospital networks from a city in Minas Gerais State, Brazil, between 2009 and 2012. RESULTS: A 40% reduction in the prevalence of community-acquired pneumonia (CAP was observed after introducing the pneumococcal conjugate vaccine. Male children were 28% more likely to develop the disease. The prevalence ratio ([PR] = 1.96, 95% CI: 1.52 to 2.53, p < 0.05 suggested that not being vaccinated was associated with the occurrence of pneumonia. The prevalence of CAP was 70% lower (PR 0.30, 95% CI: 0.24 to 0.37, p<0.05 in children vaccinated as recommended compared to children with delayed vaccination, suggesting that the updated vaccine schedule improves protection. CONCLUSIONS: Immunization with the 10-valent pneumococcal vaccine appeared to reduce the number of pneumonia cases in children during the study period. Prospective studies are needed to confirm the efficacy of the vaccine against the occurrence of pneumococcal pneumonia.

This research explored the link between coronary heart disease (CHD) prevalence and metropolitan-area level occupational structure among 137 metropolitan/micropolitan statistical areas (MMSA) in the United States. Using data from the 2006-2008 Behavioral Risk Factor Surveillance System and 2007 County Business Patterns, logistic mixed models were developed to estimate CHD prevalence between MMSAs controlling for individual-level socioeconomic characteristics and various types of occupational structure. Results showed that CHD prevalence was lower in MMSAs where their economy was dominated by 'tourism and resort' and 'the quaternary sector' and higher in MMSAs dominated by 'manufacturing', 'transportation and warehousing', and 'mining'. MMSA-level effects on CHD were found in 'tourism and resort' and 'the quaternary sector' having lower risk and 'mining' having higher risk of CHD. Although these effects prevailed in many MMSAs, some MMSAs did not fit into these effects. Additional analysis indicated a possible link between metropolitan population loss and higher CHD prevalence especially in the coal mining region of the Appalachian Mountains.

Contribution of job-exposure matrices for exposure assessment in occupational safety and health monitoring systems: application from the French national occupational disease surveillance and prevention network.
Florentin, Arnaud; Zmirou-Navier, Denis; Paris, Christophe
To detect new hazards ("signals"), occupational health monitoring systems mostly rest on the description of exposures in the jobs held and on reports by medical doctors; these are subject to declarative bias. Our study aims to assess whether job-exposure matrices (JEMs) could be useful tools for signal detection by improving exposure reporting. Using the French national occupational disease surveillance and prevention network (RNV3P) data from 2001 to 2011, we explored the associations between disease and exposure prevalence for 3 well-known pathology/exposure couples and for one debatable couple. We compared the associations measured when using physicians' reports or applying the JEMs, respectively, for these selected diseases and across non-selected RNV3P population or for cases with musculoskeletal disorders, used as two reference groups; the ratio of exposure prevalences according to the two sources of information were computed for each disease category. Our population contained 58,188 subjects referred with pathologies related to work. Mean age at diagnosis was 45.8 years (95% CI 45.7; 45.9), and 57.2% were men. For experts, exposure ratios increase with knowledge on exposure causality. As expected, JEMs retrieved more exposed cases than experts (exposure ratios between 12 and 194), except for the couple silica/silicosis, but not for the MSD control group (ratio between 0.2 and 0.8). JEMs enhanced the number of exposures possibly linked with some conditions, compared to experts' assessment, relative to the whole database or to a reference group; they are less likely to suffer from declarative bias than reports by occupational health professionals.
Full Text Available Abstract Background Although work related risk factors associated with Cardiovascular Diseases (CD have been well researched, there is no detailed knowledge regarding disparate occupational groups each with a different risk exposition. Therefore, two occupational groups (chefs and office workers were compared with a focus on nutritional and psychosocial factors. Methods Two groups of subjects were tested for work and diet-related risks of CD (45 chefs and 48 office workers. The groups matched both for gender (male and age (30 to 45 years. The study included a medical check-up, bioelectrical impedance analysis as well as an evaluation of questionnaires on health, nutritional behaviour and coping capacity. In addition, volunteers were required to compile a 7-day-dietary-record and collect their urine 24 h prior to their check-up. Blood samples drawn were analysed for glucose and lipid metabolism, homocysteine, vitamin B12, folic acid; C-reactive protein, uric acid, red blood cell fatty acids, plant sterols, antioxidative capacity and oxidative stress. Results On average, the chefs showed one risk factor more compared to the office workers. The most frequent risk factors in both groups included overweight/obesity (chef group [CG]: 62.2%; office group [OG]: 58.3% and elevated TC (CG: 62.2%; OG: 43.8%]. Moreover, although the chefs often had higher CRP-concentrations (40.0%, more office workers suffered from hypertension (37.5%. Chefs showed significant higher concentrations of saturated fatty acids and oleic acid, whereas docosahexaenoic acid, Omega-6- and trans fatty acids were found more frequently in the red blood cell membranes of office workers. While there were no significant differences in analysed plant sterols between the two occupational groups, 7,8-dihydro-8-oxo-2'-deoxyguanosine was significantly increased in office workers. Concerning the work-related psychosocial factors, the chefs were characterised by a stronger subjective importance

Forestry workers and other people who come into close contact with wild animals, such as hunters, natural science researchers, game managers or mushroom/berry pickers, are at risk of contracting bacterial, parasitological or viral zoonotic diseases. Synthetic data on the incidence and prevalence of zoonotic diseases in both animals and humans in European forests do not exist. It is therefore difficult to promote appropriate preventive measures among workers or people who come into direct or indirect contact with forest animals. The objectives of this review are to synthesise existing knowledge on the prevalence of the three predominant bacterial zoonotic diseases in Europe, i.e. Lyme borreliosis, tularemia and leptospirosis, in order to draw up recommendations for occupational or public health. 88 papers published between 1995-2013 (33 on Lyme borreliosis, 30 on tularemia and 25 on leptospirosis) were analyzed. The prevalences of these three zoonotic diseases are not negligible and information targeting the public is needed. Moreover, the results highlight the lack of standardised surveys among different European countries. It was also noted that epidemiological data on leptospirosis are very scarce.

A review is presented on the existing knowledge about the usefulness of the occupational therapy in the non-pharmacological treatment of Alzheimer's disease. After conducting a literature search of the period 2010-2015, 25 articles that met the inclusion criteria were selected. The evidence obtained showed the efficiency and effectiveness of OT in delaying the progression of various disorders, especially when structured home OT programs are used. These programs should include aerobic and strengthening, sensory stimulation, and cognitive and memory training exercises based on learning without mistakes. These have shown benefits in the performance of activities of daily living, cognitive and emotional functioning. The importance is stressed of the combined and individual household level intervention and caregiver education. Finally, the need for more studies on the effectiveness of long-term sensory stimulation is highlighted. Copyright © 2015 SEGG. Publicado por Elsevier España, S.L.U. All rights reserved.
Full Text Available Background: Objective of the study was to assess the impact of environmental and socio-economic factors to the occurrence of symptoms and diseases of the respiratory system in school children from Sosnowiec, based on the questionnaire data. Materials and methods: The crosssectional epidemiological questionnaire study was performed in the years 2005–2006. Parents of 709 primary school children aged 7–12 years took part in the study. Questionnaire was completed by parents to collect information on children health status, particularly respiratory symptoms, chronic diseases of respiratory system, allergic diseases, use of medical services, children dietary habits and family socio-economic status. Results: In the study group the statistical significance was found for the incidence of respiratory symptoms in children and housing conditions, i.e.: the number of people sleeping together with a child in the same room and dampness in the dwelling. Results of the study showed, that incidence of whizzing differed statistically significantly in the groups of different professional status of the parents. It is difficult to estimate if this is only the influence of socio-economic conditions or any other environmental factors as well. Conclusions: Results of the study demonstrated statistical significance between the status of respiratory system in children and housing occupancy rate (the number of people sleeping together with a child in the same room and dampness in the dwelling. Relation between respiratory symptoms in children, parents education and professional status was analyzed, but findings of the conducted studies do not give explicit evidence of such a relation.

Proper hand hygiene has been linked to lower susceptibility to infectious diseases in many types of communities, but it has not been well established on college campuses. This study investigated the hand hygiene statuses of college students and their occurrences in relation to infectious diseases, medical visits, and absence from classes or work. It also examined the effects of education on handwashing technique to improve hand hygiene. College students enrolled at a university in Northwestern Ohio were recruited as study subjects. Microbial samples were collected 3 times from each of the 220 valid volunteers before washing their hands, after washing with their own procedures, and after washing with a procedure recommended by the Centers for Disease Control and Prevention (CDC). Each volunteer also answered a survey including questions on their health conditions, medical visits, and absence from classes or work. Hands of 57.7% volunteers were colonized by an uncountable number of microbial colonies, which were significantly linked to more occurrences to infectious diseases (P work (P = .09). The handwashing procedure provided by the CDC significantly improved hand hygiene. It is critical to promote education on proper handwashing in colleges, in grade schools, and at home to improve health and learning outcomes.

The nymphal stage of the blacklegged tick, Ixodes scapularis Say, is considered the primary vector to humans in the eastern United States of the Lyme disease spirochete Borrelia burgdorferi sensu stricto. The abundance of infected host-seeking nymphs is commonly used to estimate the fundamental risk of human exposure to B. burgdorferi, for the purpose of environmental risk assessment and as an outcome measure when evaluating environmentally based tick or pathogen control methods. However, as this tick-based risk measure does not consider the likelihoods of either human encounters with infected ticks or tick bites resulting in pathogen transmission, its linkage to the occurrence of Lyme disease cases is worth evaluating. In this Forum article, we describe different tick-based risk measures, discuss their strengths and weaknesses, and review the evidence for their capacity to predict the occurrence of Lyme disease cases. We conclude that: 1) the linkage between abundance of host-seeking B. burgdorferi-infected nymphs and Lyme disease occurrence is strong at community or county scales but weak at the fine spatial scale of residential properties where most human exposures to infected nymphs occur in Northeast, 2) the combined use of risk measures based on infected nymphs collected from the environment and ticks collected from humans is preferable to either one of these risk measures used singly when assessing the efficacy of environmentally based tick or pathogen control methods aiming to reduce the risk of human exposure to B. burgdorferi, 3) there is a need for improved risk assessment methodology for residential properties that accounts for both the abundance of infected nymphs and the likelihood of human–tick contact, and 4) we need to better understand how specific human activities conducted in defined residential microhabitats relate to risk for nymphal exposures and bites.

The 'healthy migrant effect' (HME) hypothesis postulates that health selection has a positive effect on migrants' health outcomes, especially in the first years after migration. We examined the potential role of the HME by assessing the association between residence duration and disease occurrence. We performed a historical prospective cohort study. We included migrants who obtained residence permits in Denmark between 1 January 1993 and 31 December 2010 (n = 114,331). Occurrence of severe conditions was identified through linkage to the Danish National Patient Register. Hazard Ratios (HRs) were modelled for disease incidence by residence duration since arrival (0-5 years; 0-10 years; 0-18 years) adjusting for age and sex. Compared with Danish-born individuals, refugees and family reunited immigrants had lower HRs of stroke and breast cancer within 5 years after arrival; however, HRs increased at longer follow-up. For example, HRs of stroke among refugees increased from 0.77 (95% CI: 0.66; 0.91) to 0.96 (95% CI: 0.88; 1.05). For ischaemic heart disease (IHD) and diabetes, refugees and family reunited migrants had higher HRs within 5 years after arrival, and most HRs had increased by end of follow-up. For example, HRs of IHD among family reunited migrants increased from 1.29 (95% CI: 1.17; 1.42) to 1.43 (95% CI: 1.39; 1.52). In contrast, HRs for TB and HIV/AIDS showed a consistent decrease over time. Our analyses of the effect of duration of residence on disease occurrence among migrants imply that, when explaining migrants' advantageous health outcomes, the ruling theory of the HME should be used with caution, and other explanatory models should be included. © 2014 John Wiley & Sons Ltd.

Occupational rhinitis (OR) involves nasal congestion, rhinorrhea, nasal itching, and/or sneezing resulting from workplace exposures. OR can have a significant negative effect on quality of life and productivity. OR can be divided into allergic or nonallergic subgroups based on the underlying pathogenesis. Certain occupational exposures place employees at greater risk for developing disease. Primary treatment is avoidance of implicated exposures. Antihistamines, saline rinses, and nasal steroids may be useful. OR can coexist with occupational asthma, and rhinitis symptoms have been reported to precede those of the lower respiratory tract. OR is has both medical and socioeconomic implications. Copyright © 2016 Elsevier Inc. All rights reserved.
Full Text Available INTRODUCTION: A descriptive, entomological and seroepidemiological study on Chagas disease was conducted in a place of recent occupation on the outskirts of Cochabamba, Bolivia: Avaroa/Primer de Mayo (population:3,000, where the socio-economic level is low and no control measures have been made available. METHODS: The immunofluorescent antibody test (IFAT was used for IgG and IgM anti-Trypanosoma cruzi antibodies in filter paper bloodspot eluates from 128 subjects (73 females, 55 males selected by systematic sampling. Concerning each subject age, gender, birthplace, occupation, duration of residence and building materials used in their houses were recorded. Vectors were captured both in domestic and peridomestic environments. RESULTS: Seropositive, 12.5% (16/128: females, 15.1% (11/73; males, 9.1% (5/55. Average time of residence: 6.1 years for the whole population sample and 7.4 years for the seropositive subjects. Most houses had adobe walls (76.7% , n= 30, galvanized iron rooves (86.7% and earthen floors (53.4% 80% of the walls had crevices. One hundred forty seven specimens of Triatoma infestans were captured, of which 104 (70.7% were domestic, and 1 peridomestic Triatoma sordida. Precipitin host identification: birds, 67.5%; humans, 27.8%; rodents, 11.9%; dogs, 8.7%; cats, 1.6%. House infestation and density indices were 53.3 and 493.0 respectively. We found 21 (14.3% specimens of T. infestans infected with trypanosomes, 18 (85.7% of which in domestic environments. DISCUSSION: The elements for the vector transmission of Chagas disease are present in Avaroa/Primer de Mayo and the ancient custom of keeping guinea pigs indoors adds to the risk of human infection. In neighboring Cochabamba, due to substandard quality control, contaminated blood transfusions are not infrequent, which further aggravates the spread of Chagas disease. Prompt action to check the transmission of this infection, involving additionally the congenital and transfusional

There are many harmful factors that possess a damaging impact on the body of employees at aluminum production. It leads to the development of bronchial asthma (BA), chronic nonobstructive bronchitis (CNB) and chronic obstructive pulmonary disease (COPD). The pathogenesis of these disorders, as well as sensitizing effect offluorine in the aluminum production is not fully understood. The purpose of this work was to study the characteristics of laboratory indices in patients with occupational diseases of the respiratory system. In workers of aluminum production with the diagnosis of occupational diseases of respiratory system (15 patients with a diagnosis of asthma, 30 CNB cases, 20 COPD patients) we evaluated the content of total protein, total cholesterol, high density lipoprotein cholesterol (HDLC), total calcium, phosphorus, ceruloplasmin, hematological indices and performed emigration of leukocytes braking test (TTEEL). Clinical and biochemical profile ofpersons with occupational asthma was characterized by a low level of total calcium and ceruloplasmin, a high concentration of phosphorus in the blood serum and inhibition of leukocyte emigration in the test with sodium fluoride. For aluminum production CNB workers characteristic active proatherogenic process was pronounced by a decrease in the HDLC level and an increase in atherogenic index; higher hematocrit value and concentration of erythrocytes, and more than 50% of cases of sensitization to the presence of sodium fluoride. COPD cases had occupational lower average concentration of hemoglobin in the erythrocyte, total protein in serum, as well as polymorphic variant response to sodium fluoride in the form of a depression and activation of leucocytes emigration.

Circulating antibodies to soya-derived protein antigens have been measured in patients with duodenitis, Crohn's disease, ulcerative colitis and coeliac disease. Significantly raised antibody titres were found frequently in the coeliac group, particularly those patients showing a suboptimal response to a gluten-free diet, but rarely in subjects with other gastrointestinal diseases. Antisoya activity was not necessarily accompanied by antibodies to other common dietary antigens. We suggest that some coeliacs may have an associated dietary soya sensitivity which could adversely influence their response to gluten withdrawal. PMID:7040491
The sudden widespread appearance of oak diseases in Austria is interpreted as the delayed and cumulative effect of numerous biotic and abiotic stress factors during the past two decades. Particular importance is attached to the progressive drought stress resulting from a substantial precipitation deficit. Outbreaks of defoliating insects may have aggravated this stress and resulted in a decreased resistance to frost. The so-called T-disease is indicative of frequent frost damage. The involvement of coccids and especially various fungi (Armillaria sp.) in the disease syndrome was determined, yet considered to be of secondary importance. Tracheomycosis has not yet been recorded in Austria.
Full Text Available Charcot-Marie-Tooth neuropathy type 4B1 (CMT4B1 disease is a rare subtype of CMT4 with reported association of facial weakness, vocal cord paresis, chest deformities, and claw hands. We report the unusual occurrence of optic neuritis and cervical cord schwannoma in a male individual with confirmed CMT4B1 disease. Sequencing of the MTMR2 gene revealed a novel nonsense homozygous mutation c.1768C>T (p.Gln590*. The mutation was identified in affected relatives of the proband and a second, apparently unrelated, family. The rare association of optic neuritis or schwannoma with genetically confirmed CMT1A has been individually observed, but never with recessive CMT. To the best of our knowledge, the occurrence of optic neuritis and cervical cord schwannoma in the same patient has never been reported with any form of CMT including CMT4B1. In similar cases, we recommend immediate medical attention to rule out the possibility of schwannomas in patients with all demyelinating CMT subtypes in case of the development of focal neurological signs or acute worsening of clinical status.

The interhuman transmission, low level of personal hygiene, coprophagic habits, among others, may contribute to the dissemination of enteroparasitosis in individuals with mental diseases. The object of this paper was to verify the occurrence of enteroparasitosis in individuals with mental diseases assisted at São Marcello Nursing Home in Aracaju, Sergipe State, in the period between February and May at 2006, and track epidemiological aspects of the transmission. So, coproparasitologic exams were performed, and samples were manipulated by Hoffmann, Pons or Janner (1932) technique. The epidemiological data was obtained from questionnaires applied to the legal responsible for each individual. There were 62.22% of patients infected by at least one parasite. Inadequacies regarding sanitation, habitation and habits of personal hygiene were also observed. This study stressed the importance of a constant monitoring of parasitisms and the continuous observance of the conditions that favor their transmission.

It is unclear whether physiotherapy and occupational therapy are clinically effective and cost-effective in Parkinson disease (PD). To perform a large pragmatic randomized clinical trial to evaluate the clinical effectiveness of individualized physiotherapy and occupational therapy in PD. The PD REHAB Trial was a multicenter, open-label, parallel group, controlled efficacy trial. A total of 762 patients with mild to moderate PD were recruited from 38 sites across the United Kingdom. Recruitment took place between October 2009 and June 2012, with 15 months of follow-up. Participants with limitations in activities of daily living (ADL) were randomized to physiotherapy and occupational therapy or no therapy. The primary outcome was the Nottingham Extended Activities of Daily Living (NEADL) Scale score at 3 months after randomization. Secondary outcomes were health-related quality of life (assessed by Parkinson Disease Questionnaire-39 and EuroQol-5D); adverse events; and caregiver quality of life. Outcomes were assessed before trial entry and then 3, 9, and 15 months after randomization. Of the 762 patients included in the study (mean [SD] age, 70 [9.1] years), 381 received physiotherapy and occupational therapy and 381 received no therapy. At 3 months, there was no difference between groups in NEADL total score (difference, 0.5 points; 95% CI, -0.7 to 1.7; P = .41) or Parkinson Disease Questionnaire-39 summary index (0.007 points; 95% CI, -1.5 to 1.5; P = .99). The EuroQol-5D quotient was of borderline significance in favor of therapy (-0.03; 95% CI, -0.07 to -0.002; P = .04). The median therapist contact time was 4 visits of 58 minutes over 8 weeks. Repeated-measures analysis showed no difference in NEADL total score, but Parkinson Disease Questionnaire-39 summary index (diverging 1.6 points per annum; 95% CI, 0.47 to 2.62; P = .005) and EuroQol-5D score (0.02; 95% CI, 0.00007 to 0.03; P = .04) showed small differences in favor of therapy. There was no difference in
Four patients with occupational contact dermatitis to Lactuca sativa had cross-sensitivity to Cichorium endivia. One of the patients also had contact urticaria to Lactuca and Cichorium, and another reacted positively to scratch tests with these plants as a sign of immediate allergy. In two cases such immediate allergy was considered the cause of a vesicular, intense itching eruption within a few minutes of contact with fresh leaves of Lactuca on previously eczematous skin. The severe chronic dermatitis of the hands of these patients is ascribed to combined delayed and immediate allergy.
Inflammatory bowel diseases (IBD), consisting of Crohn's disease (CD) and ulcerative colitis (UC), are chronic immune mediated diseases of unknown aetiology. Traditionally, the highest occurrence of both UC and CD is found in North America and Europe, including Scandinavia and the United Kingdom...... years or older were included in the cohort. Annual incidence rates were twice as high in Western Europe (CD: 6.3/100,000; UC: 9.8/100,000) compared to Eastern Europe (CD: 3.3/100,000; UC: 4.6/100,000), thus confirming a gradient in IBD incidence. The incidence gradient could not be explained by marked...... treatment choices during the initial year of disease the use of biological therapy was significantly higher in Western Europe for both CD and UC, while Eastern European centres used 5-ASA more often in CD and UC. In both regions patients were treated earlier and more frequently with immunomodulators...

We investigated whether working night shifts was associated with the risk of Parkinson's disease (PD). Between January 2008 and December 2010, we recruited 1808 patients with a confirmed diagnosis of idiopathic PD from Denmark and 1876 population controls matched by year of birth and gender. Information on lifelong occupational history, including information on night work, smoking, caffeine and alcohol consumption habits, and family history of PD was collected through structured telephone interviews. Overall, there was no association between a history of night shift work and PD [odds ratio (OR) for any type of night work (ie, either permanent or rotating night work) 1.01, 95% confidence interval (95% CI) 0.86-1.21]. Compared with persons who never worked night shifts, risks of those with longer durations of night work did not appear to differ (OR <10 years=0.95, 95% CI 0.75-1.19, OR 10-19 years= 1.09, 95% CI 0.77-1.53, OR ≥20 years=1.05, 95% CI 0.81-1.37, P for trend=0.23). Associations were similar among men and women. These data suggest that working night shifts is not associated with PD or that low tolerance for night shift work is an early marker of PD. Due to the novel and exploratory nature of these findings, confirmation is needed.

Oxygen free radicals and their metabolites, collectively described as reactive oxygen species (ROS), have been implicated in the pathogenesis of many diseases. The pulmonary system is particularly vulnerable to ROS-induced injury because of its continuous exposure to toxic pollutants from a wide variety of sources in the ambient air. Additionally, lungs are exposed systemically to ROS generated from xenobiotic compounds and endogenous sources. This review describes the sources of endogenous and exogenous ROS generation in the lung. Special emphasis is given to major sources of ROS in occupational and environmental exposures to asbestos, crystalline silica, coal, chromium, herbicides, bleomycin, and cigarette smoke. ROS-induced lung injury at different target levels may contribute to similar patterns of cell injury and alterations at the molecular level by initiation, propagation, and autocatalytic chain reactions. Intracellular signalling, activation and inactivation of enzymes, stimulation, secretion, and release of proinflammatory cytokines, chemokines, and nuclear factor activation and alterations are also common events. Understanding the interactions of these intricate mechanistic events is important in the prevention and amelioration of lung injury that results from acute and chronic exposures to toxins in ambient air. 147 refs., 1 fig.

Chronic periodontal disease (CPD) is a highly prevalent, multifactorial, bacterially induced inflammatory disease, characterized by pathologic loss of periodontal attachment and alveolar bone with onset mostly in adulthood. While cross-sectional data have demonstrated significant associations between adverse socioeconomic position (SEP) and poor periodontal conditions, there is a gap in the literature on the understanding of how SEPs in different life stages impact on the occurrence of this disease later on. Life-course epidemiology offers different theoretical models to study the pathway of health and illness during the lifespan, and the hypothesis of the present study is that the relationship between SEP and CPD can be explained based on different life-course epidemiology theories: (a) critical period model; (b) critical period with modifier effect model; (c) accumulation of risk model; (d) chain-of-risk model. Under the first theoretical model, the association between SEP and CPD may be explained by an inflammatory hypothesis, considering that childhood adverse socioeconomic backgrounds alter the immunoinflammatory response that leads to disease in adulthood regardless of conditions later in life. The second model postulates that the early life SEP modifies the host immunoinflammatory response, and the risk of disease will be modified over the life-course by socio-behavioural influences. The third, "accumulation of risk model", may explain such relationship taking into account exposures during different periods of life. However, this model does not consider the moment when the exposure occurred, only taking into consideration the number of episodes during the life cycle. Finally, the potential explanation to the role of socioeconomic position on chronic periodontal disease, using a chain-of-risk model, is that early low SEP may cause social stress related to social hierarchies, what may, in turn, trigger endocrine, neural and immune changes, that reflect on

To investigate the occupational hazards among Chinese female workers in the electronics industry, the authors systematically sampled a total of 8,300 female workers at random across 4 provinces in a variety of electronics factories. A detailed questionnaire was used to collect information on occupational hazards and the occurrence of occupation-related diseases. The results show that 4,283 female workers (51.9%) were exposed to 1 or more occupational hazards. The most common chemical hazard was organic solvent, and the second most common was heavy metals. The ergonomic hazards included repetitive movements, poor standing posture, and the lifting of heavy goods. More than 60% of the female workers self-reported occupation-related diseases. These results showed that occupational health hazards were common in the electronics industry in China and that they caused serious occupation-related health problems for the female workers therein.

Full Text Available An earlier age at onset of Parkinson’s disease (PD has been reported to be associated with occupational exposures to manganese and hydrocarbon solvents suggesting that exposure to neurotoxic chemicals may hasten the progression of idiopathic PD. In this study the role of occupational exposure to metals and pesticides in the progression of idiopathic PD was assessed by looking at age at disease onset. The effects of heritable genetic risk factors, which may also influence age at onset, was minimized by including only sporadic cases of PD with no family history of the disease (n=58. Independent samples Student t-test revealed that subjects with occupational exposure to metals and/or pesticides (n=36 were significantly (p=0.013 younger than unexposed controls (n=22. These subjects were then divided into three groups [high (n=18, low (n=18, and unexposed (n=22] to ascertain if duration of exposure further influenced age at onset of PD. One-way ANOVA revealed that subjects in the high exposure group were significantly (p=0.0121 younger (mean age: 50.33 years than unexposed subjects (mean age: 60.45 years. Subjects were also stratified by exposure type (metals vs. pesticides. These results suggest that chronic exposure to metals and pesticides is associated with a younger age at onset of PD among patients with no family history of the disease and that duration of exposure is a factor in the magnitude of this effect.

OBJECTIVES: The 'healthy migrant effect' (HME) hypothesis postulates that health selection has a positive effect on migrants' health outcomes, especially in the first years after migration. We examined the potential role of the HME by assessing the association between residence duration and disease...... Ratios (HRs) were modelled for disease incidence by residence duration since arrival (0-5 years; 0-10 years; 0-18 years) adjusting for age and sex. RESULTS: Compared with Danish-born individuals, refugees and family reunited immigrants had lower HRs of stroke and breast cancer within 5 years after...... arrival; however, HRs increased at longer follow-up. For example, HRs of stroke among refugees increased from 0.77 (95% CI: 0.66; 0.91) to 0.96 (95% CI: 0.88; 1.05). For ischaemic heart disease (IHD) and diabetes, refugees and family reunited migrants had higher HRs within 5 years after arrival, and most...

Periodontal disease, progressing from gingivitis to periodontitis, affects the majority of the world population. Its pathogenesis is related to a complex interaction between environmental, microbial, genetic and other host factors, tobacco smoking being the most important environmental risk factor. Conflicting results are reported in the literature regarding the effects of smoking habits on cytogenetic damage in exfoliated oral cells. We report herein the results of a study evaluating, for the first time, the frequency of micronucleated and binucleated cells in the gingival epithelium. There was no significant elevation of these cytogenetic end-points in 43 subjects as related to smoking habits (never-smokers, ex-smokers, and current smokers) and periodontal disease (mild, moderate, or severe forms of gingivitis and periodontitis). Therefore, the overall data emerging from the present study do not support the evidence for an association between smoking habits, periodontal disease and genotoxic damage in gingival epithelial cells.

Patients with autoimmune rheumatic diseases are more susceptible to infection, owing to the underlying disease itself or to its treatment. Most commonly, infections affect the respiratory and urinary tracts. One of the etiological factors of infections in these patients is the bacteria of the genus Legionella. The aim of the study was to assess the prevalence of anti-Legionella pneumophila (L. pneumophila) antibodies in patients with autoimmune rheumatic diseases and to analyze individual and environmental risk factors for the development of Legionella infection in patients with positive antibody results. The study group consisted of 165 patients with autoimmune rheumatic diseases and 100 healthy subjects. Serum samples were tested for the presence of specific antibodies in the immunoglobulin (Ig) M and IgG classes against L. pneumophila serogroups 1 to 7 (SG 1-7) and the IgG class for serogroup 1 (SG 1). Antibodies against L. pneumophila were found in 7 patients (4%): 5 cases with antibody positivity only in the IgG class and 2 cases with antibody positivity in both classes. In patients with positive IgG antibodies for SG 1-7, specific antibodies for L. pneumophila SG 1 were not detected. In the control group, positive results were obtained in 9 cases (9%): IgM positivity in 6 (6%) and IgG positivity in 3 (3%). The frequency of antibodies to L. pneumophila in our patients is comparable to that in healthy individuals. L. pneumophila should be recognized as a potential pathogen in patients with autoimmune rheumatic diseases. Primary disease condition, immunosuppressive therapy, and other risk factors should not be ignored in these patients.

Roselle (Hibiscus sabdariffa L.) family Malvaceae is an important crop used in food, cosmetics and pharmaceutics industries. Roselle is cultivated mainly in Upper Egypt (Qena and Aswan governorates) producing 94% of total production. Root rot disease of roselle is one of the most important diseases that attack both seedlings and adult plants causing serious losses in crop productivity and quality. The main objective of the present study is to identify and characterize pathogens associated with root rot and wilt symptoms of roselle in Qena, Upper Egypt and evaluate their pathogenicity under greenhouse and field condition. Fusarium oxysporum, Macrophomina phaseolina, Fusarium solani, Fusarium equiseti and Fusarium semitectum were isolated from the natural root rot diseases in roselle. All isolated fungi were morphologically characterized and varied in their pathogenic potentialities. They could attack roselle plants causing damping-off and root rot/wilt diseases in different pathogenicity tests. The highest pathogenicity was caused by F. oxysporum and M. phaseolina followed by F. solani. The least pathogenic fungi were F. equiseti followed by F. semitectum. It obviously noted that Baladi roselle cultivar was more susceptible to infection with all tested fungi than Sobhia 17 under greenhouse and field conditions. This is the first report of fungal pathogens causing root rot and vascular wilt in roselle in Upper Egypt. PMID:24808737

We studied the clinical and pathological features of six cases of non-Hodgkin's lymphoma occuring in patients treated for Hodgkin's disease. All six patients had received both radiation therapy and chemotherapy. Abdominal or gastrointestinal involvement was present in five of the six cases. None of the patients had evidence of Hodgkin's disease when the diagnosis of non-Hodgkin's lymphoma was made. Five of the six patients were among a study group of 579 patients with Hodgkin's disease, prospectively followed since diagnosis. At 10 years the actuarial risk of development of non-Hodgkin's lymphoma in this study group is 4.4 per cent and is similar to that of developing acute leukemia: 2.0 per cent. Non-Hodgkin's lymphoma is a second tumor that may occur late in the course of patients treated for Hodgkin's disease, particularly in patients who have received both radiation therapy and chemotherapy. Like acute leukemia, non-Hodgkin's lymphoma may be another cancer that represents a substantial late risk of combined-modality therapy

Through the concept of "thought collectives" in particular, Ludwik Fleck was a pioneer in demonstrating how much scientific knowledge is inherently made up of social and historical material. In this article, I propose to follow a Fleckian path by comparing the proceedings of the 1930 International Labour Office Conference on silicosis in Johannesburg on the one hand, and on the other the content of the debates that took place in France in the 2000s to revise the "tables" of occupational diseases which define the compensation rules for salaried workers in the French general (as well as the farm) health insurance scheme. The text offers an analysis of the striking similarities between these two distant sources, pointing out particularly the repetitiveness of ignorance and knowledge, and the nature of what can be admitted as a body of "evidence" in medico-legal issues such as the definition and compensation of occupational diseases. © 2015 Wiley Periodicals, Inc.

The gut microbiome plays a key role in human health, and alterations of the normal gut flora are associated with a variety of distinct disease states. Yet, the natural dependencies between microbes in healthy and diseased individuals remain far from understood. Here we use a network-based approach to characterize microbial co-occurrence in individuals with inflammatory bowel disease (IBD) and healthy (non-IBD control) individuals. We find that microbial networks in patients with IBD differ in both global structure and local connectivity patterns. While a “core” microbiome is preserved, network topology of other densely interconnected microbe modules is distorted, with potent inflammation-mediating organisms assuming roles as integrative and highly connected inter-modular hubs. We show that while both networks display a rich-club organization, in which a small set of microbes commonly co-occur, the healthy network is more easily disrupted by elimination of a small number of key species. Further investigation of network alterations in disease might offer mechanistic insights into the specific pathogens responsible for microbiome-mediated inflammation in IBD.

Conclusions: The need for integrity in professional intervention was evident during the study. It is necessary to transcend the clinical context and consider the family and social scenario (individual case management, and to focus on user and family-centered approaches. Also, relevant topics were identified, which need to be incorporated in the daily work of occupational therapists and on which the study subject should be based for further studies, namely, bioethics and palliative care of children with chronic diseases.

Retrospective analysis of 210 cases of patients with Hodgkin's disease revealed an overall incidence of herpes zoster varicella of 9.5 per cent. Patients with the mixed cellular histological subtype showed a significantly increased (p < 0.05) risk as compared with the total population. More than 90 per cent of the herpes zoster varicella infections occurred after termination of treatment; a combination of radiotherapy with chemotherapy proved to be a predisposing factor. (Auth.)

In despite of the intestinal parasites are very important, because constitutes a severe problem to public health, contributing to the aggravation of the social, economical and medical problems. Thus, the objective of this study was to verify the occurrence of the most frequent enteroparasites among children (0-10 years old, in the Health Family Program (PSF area situated in the district of Morro Alto in Vespasiano city, state of Minas Gerais,Brazil. It was analyzed 3250 handbook indexes of three PSF units. The general occurrence was 18.4% positive and some children have more than one parasite. The most founded enteroparasitos was Giardia lamblia (43%, Ascaris lumbricoides (34% and Entamoeba coli (13%. The 6 to 8 ages shows the highest incidence of children with parasites. The data collected to this project evidenced that Vespasiano-city doesn’t have related researches to parasites, justifying the importance of this study and its results offers subsidies for elaboration of municipal public health policies for childhood and youth.

The planet's mean air and ocean temperatures have been rising over the last century because of increasing greenhouse gas (GHG) emissions. These changes have substantial effects on the epidemiology of infectious diseases. We describe direct and indirect processes linking climate change and infectious diseases in livestock with reference to specific case studies. Some of the studies are used to show a positive association between temperature and expansion of the geographical ranges of arthropod vectors (e.g. Culicoides imicola, which transmits bluetongue virus) while others are used to illustrate an opposite trend (e.g. tsetse flies that transmit a range of trypanosome parasites in sub-Saharan Africa). We further describe a positive association between extreme events: droughts and El Niño/southern oscillation (ENSO) weather patterns and Rift Valley fever outbreaks in East Africa and some adaptation practices used to mitigate the impacts of climate change that may increase risk of exposure to infectious pathogens. We conclude by outlining mitigation and adaptation measures that can be used specifically in the livestock sector to minimize the impacts of climate change-associated livestock diseases.

Anthrax is caused by Bacillus anthracis, which can naturally infect livestock, wildlife and occupationally exposed humans. However, for its resistance due to spore formation, ease of dissemination, persistence in the environment and high virulence, B. anthracis has been considered the most serious bioterrorism agent for a long time. During the last century anthrax evolved from limited natural disease to potentially global threat if used as bioweapon. Several factors may mitigate the consequences of an anthrax attack, including 1. the capability to promptly recognize and manage the illness and its public health consequences; 2. the limitation of secondary contamination risk through an appropriate decontamination; and 3. the evolution of genotyping methods (for microbes characterization at high resolution level) that can influence the course and/or focus of investigations, impacting the response of the government to an attack. A PubMed search has been done using the key words “bioterrorism anthrax”. Over one thousand papers have been screened and the most significant examined to present a comprehensive literature review in order to discuss the current knowledge and strategies in preparedness for a possible deliberate release of B. anthracis spores and to indicate the most current and complete documents in which to deepen. The comprehensive analysis of the two most relevant unnatural anthrax release events, Sverdlovsk in the former Soviet Union (1979) and the contaminated letters in the USA (2001), shows that inhalational anthrax may easily and cheaply be spread resulting in serious consequences. The damage caused by an anthrax attack can be limited if public health organization, first responders, researchers and investigators will be able to promptly manage anthrax cases and use new technologies for decontamination methods and in forensic microbiology.

Occupational skin diseases (OSD) have a high medical, social, economic and political impact. Knowledge dissemination from research activities to key stakeholders involved in health care is a prerequisite to make prevention effective. To study and prioritize different activity fields and stakeholders that are involved in the prevention of OSD, to reflect on their inter-relationships, to develop a strategic approach for knowledge dissemination and to develop a hands-on tool for OSD prevention projects METHODS: Seven different activity fields that are relevant in the prevention of OSD have been stepwise identified. This was followed by an impact analysis. Fifty-five international OSD experts rated the impact and the influence of the activity fields for the prevention of OSD with a standardized questionnaire. Activity fields identified to have a high impact in OSD prevention are the political system, mass media and industry. The political system has a strong but more indirect effect on the general population via the educational system, local public health services or the industry. The educational system, mass media, industry and local public health services have a strong direct impact on the OSD 'at risk' worker. Finally, a hands-on tool for future OSD prevention projects has been developed that addresses knowledge dissemination and different stakeholder needs. Systematic knowledge dissemination is important to make OSD prevention more effective and to close the gap between research and practice. This study provides guidance to identify stakeholders, strategies and dissemination channels for systematic knowledge dissemination which need to be adapted to country-specific structures, for example the social security system and healthcare systems. A key for successful knowledge dissemination is building linkages among different stakeholders, building strategic partnerships and gaining their support right from the inception phase of a project. © 2017 European Academy of

To investigate the distribution of authors, funding, institutions, and regions in Chinese Journal of Industrial Hygiene and Occupational Diseases between 2006 and 2013, to understand the types and characteristics of cooperation, and to identify the core authors, core institutions, and core regions. Based on the Chinese Science Citation Database, the data on the journal were analyzed by bibliometric methods, including the number of papers, cooperation, core authors, regional distribution of authors, systematic distribution of authors, productive institutions, and funding sources and distribution. Within the eight years, there were 2488 papers published in the journal, and 1363 authors published only one paper in the journal, accounting for 76.57%of the number of first authors. A total of 2304 (92.60%) out of 2488 papers were published by co-authors and the degree of cooperation was 4.64. One hundred and eighty-four papers (7.40%) were published by only one author. There were 64 (3.60%) core authors who published 324 papers (13.02%). Nine hundred and sixty-eight papers (38.91%) were published by research institutes, 825 papers (33.16%) by universities, and 272 papers (10.93%) by affiliated hospitals of medical universities. There were 19 productive institutions publishing 838 papers (33.68%), in which Beijing ranked first with 300 papers (12.06%). The journal has a large number of authors, extensive institutions, a wide regional distribution, a high cooperation rate, and a strong ability to attract funded papers. Research institutes and universities are the main sources of papers in the journal.
Full Text Available Paratuberculosis or Johne’s disease is an infectious disease in ruminants (cattle, buffalo, sheep and goat caused by Mycobacterium avium subspecies paratuberculosis (MAP and characterized by granulomatous enteritis manifestation. The disease occurs worldwidely and causes great economic losses on domestic livestock industries. Calves are commonly infected soon after birth, with incubation period of either some months or years. Clinical signs observed from 2 to 10 years old of infected cattle are chronic diarrhea and progressive emaciation. Transmission of MAP to calves can occur by nursing the infected dam or got contaminated by fecal material. The pathogens can also be excreted in colostrum or milk, that is why calf can be infected since neonatal period. Infection in progress leads to cause thickening of the intestinal wall, granulomatous and mesenterical lymphnode, which diffusion lesions in the intestine are characterized by the macroscopical finding. In Indonesia, paratuberculosis had been reported in dairy cattle (in West Java with seroprevalence of 1.67% (3/180. From the serological positive reactors demonstrated MAP of 0.55% (1/180 by fecal cuture examination. Some samples of cattle and buffaloes from North Sumatera were also found positive paratuberculosis antibody against MAP detected by Complement Fixation Test (CFT at average of 4% (2/50. The presence of positive reactors of paratuberculosis in dairy cattle, beef cattle and buffaloes in Indonesia must be anticipated. These animals are carriers and can shed pathogens, although they do not show clinical signs. It is likely that paratuberculosis can not be detected by conventional diagnostic techniques, therefore, sensitive and early diagnosis techniques must be developed.

Effective public health surveillance is important for national secu- rity. With novel emerging infectious diseases being reported across different parts of the world, there is a need to build effective bio- surveillance systems that can track, monitor and report such events in a timely manner. Additionally, there is a need to identify sus- ceptible geographic regions/populations where these diseases may have a significant impact and design preemptive strategies to tackle them. With the digitization of health related information through electronic health records (EHR) and electronic healthcare claim re- imbursements (eHCR), there is a tremendous opportunity to ex- ploit these datasets for public health surveillance. In this paper, we present our analysis on the use of eHCR data for bio-surveillance by studying the 2009-2010 H1N1 pandemic flu season. We present a novel approach to extract spatial and temporal patterns of flu in- cidence across the United States (US) from eHCRs and find that a small, but distinct set of break-out patterns govern the flu and asthma incidence rates across the entire country. Further, we ob- serve a distinct temporal lag in the onset of flu when compared to asthma across geographic regions in the US. The patterns extracted from the data collectively indicate how these break-out patterns are coupled, even though the flu represents an infectious disease whereas asthma represents a typical chronic condition. Taken to- gether, our approach demonstrates how mining eHCRs can provide novel insights in tackling public health concerns.

The bovine brucellosis clinical surveillance system implemented in France aims to detect early any case of bovine brucellosis, a disease of which the country has been declared free since 2005. It relies on the mandatory notification of every bovine abortion. Following the spread of the Schmallenberg virus (SBV) in France in 2012 and 2013, and the implementation in 2012 of a clinical surveillance programme of Q fever based on abortion notifications in ten pilot départements, our objective was to study whether these two events influenced the brucellosis clinical surveillance system. The proportion of notifying farmers was analyzed over each semester from June 1, 2009 to June 30, 2013 according to the size and production type of herds, SBV status of départements and the implementation of the Q fever surveillance. Our analysis showed a slight increase in the proportion of notifying farmers as départements became infected by SBV, and after the implementation of Q fever surveillance (during the first semester of 2013). These variations might be explained by an increase in abortion occurrence (congenital deformities in newborns, due to SBV) and/or by an increase in farmers' and veterinarians' awareness (due to the spread of SBV and the implementation of the Q fever surveillance). These results highlight the difficulties in interpreting variations in the proportion of notifying farmers as a consequence of an increase in abortion occurrence. As bovine abortion surveillance can play an important role in the early warning for several diseases, there is a need to explore other ways to monitor abortions in cattle, such as syndromic surveillance using the dates of artificial insemination or calving data.

Cardiovascular diseases are a leading cause of death in the majority of developed, as well as in many developing countries. The aim of this study was to determine cardiovascular risk factors in student population and to suggest possible measures for prevention. The study was carried out during 2007-2008 at the School of Medicine, University of Nis. It included 824 students in their final year (220 males, 604 females). There was no significant difference in prevalence of hypertension among the male (1.81%) and female students (0%). The prevalence of obesity (Body Mass Index - BMI > 30 kg/m2) was significantly higher (p cardiovascular risk factors, it was determined that in the male student population systolic blood pressure correlated significantly with diastolic blood pressure, BMI and waist size, whereas age correlated with sistolic blood pressure, waist size and smoking. In the female students sistolic blood pressure correlated with diastolic blood pressure, BMI and waist size; diastolic blood pressure correlated with BMI and physical inactivity; cigarette smoking correlated with alcohol consumption and age. Cardiovascular risk factors are present in the final-year students of the School of Medicine, University of Nis. It is necessary to insist on decreasing obesity prevalence, cigarette and alcohol consumption, and on increasing physical activity of students in order to prevent cardiovascular diseases.

Italy is the main recipient of asylum seekers in the European region, and Sicily is their first point of arrival. This geographical position creates a large job for Health Authorities to identify and deal with the health of immigrants. This study evaluates the prevalence of disease among asylum seekers, assessing which are associated factors. A cross-sectional study was conducted to analyse demographic and clinical data in an Acceptance Centres for Asylum Seekers from February 2012 to May 2013. All variables that were found to be significant on unvariable analysis for the most frequent pathologies were included in a multivariable logistic regression model. Post-traumatic stress disorders with 17.4% and major depression with 7.3% were the most frequent diseases. The factors associated with post-traumatic stress disorders among asylum seekers were: major depression diagnosis (OR=2.91, p=0.004), Pakistan as a country of origin (OR=3.88, pasylum seekers needs special attention, and interventions should be done to prevent the consolidation of psychiatric morbidity. A short psychological screening after the arrival might prove helpful here. Moreover, carefully designed longitudinal studies should be carried out when political recommendations try to change the organization of psychological and healthcare services.

Immunoglobulin (Ig) A deficiency is a primary immunodeficiency in which autoimmunity is frequently observed. Thirty to fifty percent of patients with spontaneous chronic urticaria have autoantibodies that are able to cross-link FcεRI on mast cells and basophils. We investigated whether spontaneous chronic urticaria in patients with IgA deficiency meets the criteria for autoimmunity. Four patients were screened for positivity to a skin prick test and an autologous serum skin test and for the presence of other autoimmune diseases. Patient sera were tested for the ability to activate basophils and mast cells in vitro by measuring surface CD63 expression and β-hexosaminidase release, respectively. The autologous serum test was positive in all patients, and patient sera were found to induce CD63 upregulation on basophils and degranulation of an LAD2 mast cell line. Moreover, all patients were affected by other autoimmune disorders. For the first time, these data point out chronic autoimmune urticaria in subjects with an IgA deficiency and confirm that different autoimmune disorders are common among patients with an IgA deficiency. Patients with chronic autoimmune spontaneous urticaria should be screened for IgA deficiency, especially if they are affected by other autoimmune disorders. Thus, spontaneous urticaria could mirror more complex systemic diseases, such as immune deficiency. © 2016 S. Karger AG, Basel.

Polycystic kidney disease (PKD) is an inherited autosomal kidney disease which is most commonly identified in Persian and Persian related cats. Positive cats have multiple cysts of various sizes that occur in the renal cortex and medulla and occasionally in other abdominal organs. PKD often leads to renal failure which occurs from mid to late in life. Renal cysts can be diagnosed ultrasonographically after 7 weeks of age by an experienced ultrasonographer and a high resolution machine. However, ultrasonography is now being replaced by genetic screening. A total of 340 cats of variable breeds aged from 5 months to 18 years were ultrasonographically examined in the past 7 years at the University Veterinary Small Animal Clinic. Of these, 13.8% were PKD positive with very high prevalence in Persian cats (36%). There was no sex predilection identified. The C>A transversion at position 3284 on exon 29 of PKD1 gene, resulting in a stop mutation has been identified in the heterozygous state in eight affected cats examined (Persian breed). All heterozygous cats were also ultrasonographically positive.

Nowadays, in Italy the reports of mnusculoskeletal diseases increase as confirmed in the last INAIL (national insurance for occupational diseases and injuries) annual report. The Emilia-Ronmagna is one of the region with the highest number of reports: 15.9% of the total in 2012. The decree no. 81/08 has partially simplified the medico-legal activities related to musculoskeletal diseases; however, the medico-legal physicians have still to deal with some issues such as risk assessment quality, economic crisis, and specific work environments (e.g. agriculture and many handicraft activities). Tire risk factors of musculoskeletal diseases and their assessments are quite well studied. The latency period of these diseases needs to be investigated, since it could be a relevant aspect for legal medical judgment, insurance protection and prevention. Based on literature data and INAIL experience, authors propose some considerations useful for a scientific debate.

Creutzfeldt-Jakob disease (CJD) is a rare transmissible neurodegenerative disorder. The etiology of sporadic form of CJD remains unsolved. In addition to the codon 129 polymorphism, polymorphisms in the non-coding region of PRNP are considered as important factors in sCJD development. To assess a possible association between PRNP 1368 SNP and sCJD, we compared the genotype, allele and haplotype frequencies of the 1368 SNP among 46 sCJD patients of Dutch origin with the respective frequencies in healthy controls. We detected a significant association between sCJD and 1368T/T genotype. A significant difference was also observed in 1368 alleles’ distribution. In the haplotype analysis, haplotype 1368C-129G was associated with decreased risk of sCJD in Dutch population. Our findings support the hypothesis that genetic variations in the regulatory region of the PRNP gene may influence the pathogenesis of sCJD. PMID:22895088

We report the case of a female patient in whom gluten-induced entheropathy was revealed at the age of 71 yr by resistance to treatment with levothyroxine (L-T4), calcium carbonate and alfacalcidol. Hypothyroidism and hypoparathyroidism were the consequence of a total thyroidectomy performed at the age of 65 yr for a large multinodular goiter. Six months after thyroid ablation the patient started to complain of abdominal pain, diarrhea and weight loss. Following, anemia and osteopenia were documented. A progressive increase of replacement therapy for hypothyroidism and hypoparathyroidism was necessary. The clinical presentation suggested a malabsorption syndrome: celiac disease (CD) was diagnosed by serological markers and duodenal biopsy. Following gluten-free diet a normalization of clinical and serological findings was observed, bone mass density improved and a reduction of L-T4, calcium and vitamin D requirements was observed.

Occupational rhinitis is characterized by nasal congestion, rhinorrhea, nasal itching, and/or sneezing that occur secondary to exposures in the workplace. This disease can be classified into allergic or nonallergic subgroups based upon the underlying disease pathogenesis as well as the type of causative agent. While the true prevalence of occupational rhinitis is unknown, there are certain professions and occupational exposures that place workers at a higher risk for developing the disease. Additionally, occupational rhinitis can be associated with occupational asthma and upper airway symptoms may precede those of the lower respiratory tract. Taken together, occupational rhinitis is an important disease for study given its medical as well as socioeconomic implications. This review will focus on the classification of occupational rhinitis as well the prevalence, diagnosis, and treatment strategies.

Abnormalities in pulmonary function have been reported in association with chronic liver disease of varied etiology. The aim of this study was to better define the frequency and nature of these abnormalities in patients who were being evaluated for liver transplantation. We performed a battery of pulmonary function tests and chest radiographs in 116 consecutive patients (50 men, 66 women; aged 19 to 70 years, mean 44.6 years) with severe advanced liver disease who were hospitalized specifically for evaluation for possible orthotopic liver transplantation and were able to perform technically satisfactory tests. In 17 patients, quantitative whole-body technetium-99m macroaggregated albumin perfusion scanning was also performed for assessment of possible right-to-left shunting through intrapulmonary vascular dilatations. The most commonly affected test of lung function was the single-breath diffusing capacity for carbon monoxide (DLCO), which was abnormal in 48%, 45%, and 71% of patients who never smoked, former smokers, and current smokers, respectively. Ventilatory restriction was noted in 25% of all patients, airflow obstruction (reduced ratio of forced expiratory volume in 1 second to forced vital expiratory volume in 1 second to forced vital capacity) in only 3%, and a widened alveolar-arterial oxygen gradient in 45%. Diffusion impairment was accompanied by a restrictive defect in only 35% of the patients and by an abnormally widened alveolar-arterial oxygen gradient in 60%. When diffusion impairment was accompanied by an oxygenation defect, it was also associated with a significantly increased right-to-left shunt fraction (mean 24.9%) assessed from quantitative whole-body perfusion imaging

Bovine respiratory syncytial virus (BRSV) is one of the major pathogens involved in the bovine respiratory disease (BRD) complex. The seroprevalence to BRSV in Norwegian cattle herds is high, but its role in epidemics of respiratory disease is unclear. The aims of the study were to investigate the etiological role of BRSV and other respiratory viruses in epidemics of BRD and to perform phylogenetic analysis of Norwegian BRSV strains. BRSV infection was detected either serologically and/or virologically in 18 (86%) of 21 outbreaks and in most cases as a single viral agent. When serology indicated that bovine coronavirus and/or bovine parainfluenza virus 3 were present, the number of BRSV positive animals in the herd was always higher, supporting the view of BRSV as the main pathogen. Sequencing of the G gene of BRSV positive samples showed that the current circulating Norwegian BRSVs belong to genetic subgroup II, along with other North European isolates. One isolate from an outbreak in Norway in 1976 was also investigated. This strain formed a separate branch in subgroup II, clearly different from the current Scandinavian sequences. The currently circulating BRSV could be divided into two different strains that were present in the same geographical area at the same time. The sequence variations between the two strains were in an antigenic important part of the G protein. The results demonstrated that BRSV is the most important etiological agent of epidemics of BRD in Norway and that it often acts as the only viral agent. The phylogenetic analysis of the Norwegian strains of BRSV and several previously published isolates supported the theory of geographical and temporal clustering of BRSV.

The study was carried out during 2007-2008 at the School of Medicine, University of Niš. It included 824 students in their final year (220 males, 604 females. Results. There was no significant difference in prevalence of hypertension among the male (1.81% and female students (0%. The prevalence of obesity (Body Mass Index - BMI > 30 kg/m2 was significantly higher (p < 0.001 in the male (7.27% than in the female population (1.32%. Abdominal obesity was also more frequently encountered (p < 0.01 in the male (9.09% than in female population (1.32%. Every fourth student smoked cigarettes with no significant difference between the male and female students. Alcohol consumption was a significantly higher problem (p < 0.001 in the male population (18.18% than in the female one (2.65%. Physical inactivity was more often found (p < 0.001 in the female students (65.56%, than in male ones (36.36%. By the bivariate correlation of cardiovascular risk factors, it was determined that in the male student population systolic blood pressure correlated significantly with diastolic blood pressure, BMI and waist size, whereas age correlated with sistolic blood pressure, waist size and smoking. In the female students sistolic blood pressure correlated with diastolic blood pressure, BMI and waist size; diastolic blood pressure correlated with BMI and physical inactivity; cigarette smoking correlated with alcohol consumption and age. Conclusion. Cardiovascular risk factors are present in the final-year students of the School of Medicine, University of Niš. It is necessary to insist on decreasing obesity prevalence, cigarette and alcohol consumption, and on increasing physical activity

Full Text Available During 2012 to 2014, a survey for the presence of viral diseases in yam plants was carried out in a field of the Institute for Bioresources Research in Gyeongsangbuk-do, Korea. A total of 88 leaf samples were collected and tested by reverse transcription polymerase chain reaction using specific primer sets. Eighty-one samples were positive for Broad bean wilt virus 2 (BBWV2, Chinese yam necrotic mosaic virus (ChYNMV, Cucumber mosaic virus (CMV, Japanese yam mosaic virus (JYMV, and Yam mild mosaic virus (YMMV, whereas Yam mosaic virus (YMV was not detected. Additionally, seven samples were negative for all viruses. Several samples exhibited mixed (double and triple infections. Three viruses (CMV, JYMV, and YMMV were detected for the first time in yam plants in Korea. A BLAST search showed that three viruses shared nucleotide identities with CMV-Ca (98%, JYMV-O2 (91%, and YMMV-TG_NH_1 (86%. Thus, our findings confirmed that yam plants cultivated in Korea were infected with multiple viruses with three of these viruses reported for the first time in Korea.

Botulism caused by neurotoxins of Clostridium (C.) botulinum is a rare, but serious life-threatening disease in humans and animals. Botulism in livestock is usually caused by the oral uptake of C. botulinum neurotoxins (BoNT) via contaminated feed and is characterized by flaccid paralysis. In the recent past a new syndrome caused by BoNT in dairy cattle was postulated. It was supposed that C. botulinum is able to colonize the lower intestine and may subsequently produce neurotoxin. The continuous resorption of small amounts of these BoNT may then provoke the so called syndrome of "chronic" or "visceral" botulism involving unspecific clinical symptoms, reduced performance of dairy cows and massive animal losses in the affected herd. To test this hypothesis a case-control study was conducted involving 92 affected farms and 47 control farms located in Northern Germany. Fecal samples of 1388 animals were investigated for the presence of BoNT to verify the key requirement of the hypothesis of chronic botulism. BoNT was not detected in any of the fecal samples using the most sensitive standard method for BoNT detection, the mouse bioassay. Therefore, the existence of "chronic" or "visceral" botulism could not be proven. Copyright © 2015 The Authors. Published by Elsevier B.V. All rights reserved.

Purpose: To investigate whether influence at work modifies the association between demanding and strenuous occupational physical activity (OPA) and risk of ischaemic heart disease (IHD). Methods: A sample of 12,093 nurses aged 45–64 years from the Danish Nurse Cohort Study was followed for 20.......6 years by individual linkage to incident IHD in the Danish National Patient Registry. Information on OPA, influence at work, other occupational factors and known risk factors for IHD was collected by self-report in 1993. Results: During follow-up 869 nurses were hospitalised with incident IHD. Nurses...... exposed to strenuous OPA and low influence at work had a 46% increased risk of IHD [hazard ratio (HR) 1.46 (95% confidence interval (CI) 1.02–2.09)] compared to the reference group of nurses with moderate OPA and high influence at work. Nurses exposed to strenuous OPA and high influence at work were...
Full Text Available Aquaculture represents the fastest growing animal husbandry in many countries. However, higher intensity of fish farming can pose higher health hazards, too. We monitored the health status of fish from one fish farm in South Bohemia and discovered the main health problems in the breeding. For two years we examined a total of 224 specimens of brook trout (Salvelinus fontinalis, 126 specimens of hybrids (S. fontinalis × S. alpinus, 49 specimens of rainbow trout (Oncorhynchus mykiss – all clinically healthy, and 100 clinically diseased or freshly dead fish. We registered skin erosions mainly in the caudal peduncle and tail fin. Two parasite species were identified (one protist Ichthyophthirius multifiliis and one nematode Raphidascaris acus by parasitological examination. The epidemiological indicators of I. multifiliis were low. The prevalence of adult R. acus was 0–86% with a maximum in June. From November, capsules with larval stages of R. acus appeared in internal organs. Their highest intensity (200 pieces and prevalence (100% were detected in October. By microbiological examination of skin and gills, we identified changes in the density of bacterial population and its species composition dependent on water temperature and fish density. The most important problem on the monitored fish farm seems to be furunculosis of salmonid fish in all clinical forms, and the high intensity of larval stages of R. acus. The originality of this study is based on the fact that the observed breeding employs the first Danish recirculation system in the Czech Republic and no recent information about health problems has been available.

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

Full Text Available ABSTRACT Objective To examine the prevalence of the behavioral risk factors – both isolated and clustered – for chronic diseases, among adolescents. Additionally, its association with various social and demographic variables was estimated. Methods This was a cross-sectional study conducted on 1,039 high school students, from public and private schools, elected for convenience, in Rio de Janeiro, Brazil. A Chi-square test, Mann-Whitney U test, as well as crude and adjusted ordinal logistic regression were used to assess the association between the variables. Results The most frequently observed risk factors were sedentary behavior (68.8%, alcohol consumption (36.8%, and overweight (26.8%. The clustering of risk factors was observed in 67.5% of the students. Being a girl (OR=1.28; 95%CI=1.01–1.63, Caucasian (OR=1.35; 95%CI=1.06–1.72 or private school student (OR=1.46; 95%CI=1.12–1.88 increased the chance of the clustering of risk factors. The co-occurrence of risk factors was predominantly observed in the case of smoking (OR=4.94; 95%CI=1.46–16.75, alcohol consumption (OR=1.43; 95%CI=1.09–1.88, high consumption of ultra-processed foods (OR=1.57; 95%CI=1.19–2.07, and sedentary behavior (OR=1.40; 95%CI=1.07–1.82. Conclusion The co-occurrence of behavioral risk factors was observed to be higher among girls, Caucasian adolescents, and private school students, as well as, among smokers, alcohol users and adolescents with sedentary habits and a high consumption of ultra-processed foods.

BACKGROUND: In order to support occupational health practitioners, researchers, and experts (clinical librarians, guideline developers) who search the scientific literature in PubMed (Medline), we developed and evaluated an easy-to-use and effective search strategy. METHODS: We tested different
Full Text Available Disability is a social phenomenon that can not be ruled out by any society. The potential of society in combating the growth of disability – as a social evil – is determined not only by the degree of understanding of this problem but mainly by economic resources. The risk of developing occupational diseases in the coal industry is 5-10 times higher than in other branches of industry. In Ukraine, about 3 million people work under the harmful conditions of production, 60.0% of them are miners. The study analyzed the dynamics of disability as a result of occupational diseases in the Lviv region for the period 2015-2017. The results of the study prove that the disability indicators due to occupational diseases tend to grow. The ways to overcome this unfavorable tendency should be state measures on improvement of normative and legal documents, coherence between different state institutions and strengthening effective state control over hygiene norms in industries with harmful factors.

Field experiments examining target-oriented variable-rate fungicide spraying were performed in 2015 and 2016. The spray volume was adapted in real time to the local green coverage level of winter wheat (Triticum aestivum L.), which was detected using a camera sensor. Depending on the growth heterogeneity in the three strip trials in 2015, fungicide savings in the sensor-sprayed strip compared with the adjacent uniformly sprayed strip were 44%, 45% and 1%. In the 2016 field trial, the saving was 12%. There was no greater level of senescence or disease occurrence, and no higher yield losses in the camera-controlled variable-rate sprayed strips compared with the adjacent uniformly sprayed strips. From an ecological and economical point of view, sensor-controlled variable-rate spraying technology, which uses the level of green crop coverage as the plant parameter to adapt the spray volume locally, can be an alternative to the common practice of uniform spraying. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Identification and quantification of pathogen threats need to be a priority for the Canadian swine industry so that resources can be focused where they will be most effective. Here we create a tool based on a Bayesian Belief Network (BBN) to model the interaction between biosecurity practices and the probability of occurrence of four different diseases on Canadian swine farms. The benefits of using this novel approach, in comparison to other methods, is that it enables us to explore both the complex interaction and the relative importance of biosecurity practices on the probability of disease occurrence. In order to build the BBN we used two datasets. The first dataset detailed biosecurity practices employed on 218 commercial swine farms across Canada in 2010. The second dataset detailed animal health status and disease occurrence on 90 of those farms between 2010 and 2012. We used expert judgement to identify 15 biosecurity practices that were considered the most important in mitigating disease occurrence on farms. These included: proximity to other livestock holdings, the health status of purchased stock, manure disposal methods, as well as the procedures for admitting vehicles and staff. Four diseases were included in the BBN: Porcine reproductive and respiratory syndrome (PRRS), (a prevalent endemic aerosol pathogen), Swine influenza (SI) (a viral respiratory aerosol pathogen), Mycoplasma pneumonia (MP) (an endemic respiratory disease spread by close contact and aerosol) and Swine dysentery (SD) (an enteric disease which is re-emerging in North America). This model indicated that the probability of disease occurrence was influenced by a number of manageable biosecurity practices. Increased probability of PRRS and of MP were associated with spilt feed (feed that did not fall directly in a feeding trough), not being disposed of immediately and with manure being brought onto the farm premises and spread on land adjacent to the pigs. Increased probabilities of SI

An exploratory qualitative case study investigated how different sectors of a highly industrialized community mobilized in the 1990s to help workers exposed to asbestos. For this study, thirty key informants including representatives from industry, workers, the community, and local politicians participated in semi-structured interviews and focus groups. The analysis was framed by a "Dimensions of Community Change" model. The informants highlighted the importance of raising awareness, and the need for leadership, social and organizational networks, acquiring skills and resources, individual and community power, holding shared values and beliefs, and perseverance. We found that improvements in occupational health and safety came from persistently communicating a clearly defined issue ("asbestos exposure causes cancer") and having an engaged community that collaborated with union leadership. Notable successes included stronger occupational health services, a support group for workers and widows, the fast-tracking of compensation for workers exposed to asbestos, and a reduction in hazardous emissions. © The Author(s) 2015.

Recent studies indicate that physically demanding work is a risk factor for heart disease among men, especially those with low or moderate physical activity during leisure time. Among women, present evidence is inconclusive. The design was a prospective cohort study. This investigation in the Danish Nurse Cohort Study included 12,093 female nurses aged 45-64 years, who answered a self-report questionnaire on physical activity at work and during leisure time, known risk factors for ischaemic heart disease (IHD) and occupational factors at baseline in 1993. Information on the 15-year incidence of IHD was obtained by individual linkage in the National Register of Hospital Discharges to 2008. During follow-up 580 participants were hospitalised with IHD. A significant interaction between occupational and leisure time physical activity was found with the lowest risk of IHD among nurses with the combination of moderate physical activity at work and vigorous physical activity during leisure time. Compared to this group high physical activity at work was associated with a higher risk of IHD at all levels of physical activity during leisure time increasing from hazard ratio 1.75 (95% confidence interval (CI) 1.10-2.80) among nurses with vigorous physical activity during leisure time to 2.65 (95% CI 1.44-4.88) among nurses being sedentary during leisure time. This study among Danish nurses suggests that high physical activity at work is a risk factor for IHD among women. Vigorous physical activity during leisure time lowered but did not completely counteract the adverse effect of occupational physical activity on risk of IHD. © The European Society of Cardiology 2014.

To compare the effects of dust exposure and smoking on mortality of respiratory system diseases (RSD). Based on the Guangzhou Occupational Health Surveillance Record System established between 1989 and 1992, 80,987 factory workers, aged 30 years old or older, occupationally exposed or not exposed to dusts, were included in a prospective cohort study. (1) The mean age of the cohort was 43.5. Most subjects were workers, had secondary education, and almost all were married. The dust exposure rate was 16.3%, the smoking rate 43.7% and the alcohol-drinking rate 33.5%. (2) The cohort was followed up for 8 years on average, but 35 people (0.04%) were lost for follow up. Among the 1593 deaths, 219 and 90 people died of lung cancer and non-cancer respiratory system diseases (NCRSD) respectively. (3) The adjusted relative risk (RR) of death of lung cancer for smokers, 3.32, was 2.2 times of that for dust exposed workers, 1.53, and the RR of death of NCRSD for dust exposed workers, 2.41, 1.28 times of that for smokers, 1.89, especially for silica dust-exposed workers, 5.72, 3.03 times of that for smokers. Dust exposure combined with smoking caused significantly higher RR of death of RSD. (4) In male, the death risks of RSD were increased with the amount of smoking per day and years of smoking. Occupational dust exposure and smoking may cause excessive lung cancer and NCRSD death with synergistic effects. Smoking has higher RR of Lung cancer death than dust exposure. However, the dust exposure contributes to higher RR of NCRSD death. There is a significant dose-effect relationship between smoking and the death risk of RSD.

It is well known that pesticides are widely used compounds. In fact, their use in agriculture, forestry, fishery and the food industry has granted a huge improvement in terms of productive efficiency. However, a great number of epidemiological surveys have demonstrated that these toxic compounds can interact and exert negative effects not only with their targets (pests, herbs and fungi), but also with the rest of the environment, including humans. This is particularly relevant in the case of workers involved in the production, transportation, preparation and application of these toxicants. Accordingly, a growing body of evidence has demonstrated the correlation between occupational exposure to pesticides and the development of a wide spectrum of pathologies, ranging from eczema to neurological diseases and cancer. Pesticide exposure is often quite difficult to establish, as many currently used modules do not take into account all of the many variables that can occur in a diverse environment, such as the agricultural sector, and the assessment of the real risk for every single worker is problematic. Indeed, the use of personal protection equipment is necessary while handling these toxic compounds, but education of workers can be even more important: personal contamination with pesticides may occur even in apparently harmless situations. This review summarises the most recent findings describing the association between pesticide occupational exposure and the development of chronic diseases. PMID:27748877

Research indicates that dairy farmers have an elevated risk of work-related adverse health outcomes. This case-control study evaluated the characteristics of and risk factors for compensated occupational injury and disease claims among Finnish dairy farmers. The cases consisted of 19 farm couples in which both spouses had a history of multiple claims. There were 283 claims in total, a rate of 26.6 claims per 100 person-years. The controls consisted of 12 couples in which neither spouse had compensated or rejected claims during their work history as insured farmers. A combined mail/telephone survey charted potential risk factors for compensated claims. These claims frequently involved work tasks and causes related to animal husbandry. Cattle were the most common cause for injuries in general and for serious injuries in particular. Gender differences in farm work and claims were observed. Using logistic regression analyses, we identified personal and work-related risk factors including long work history, small-scale dairy farm operation, and conventional stanchion barn for dairy cattle. Outdated working conditions, while not statistically significant, were positively associated with claims as well. Declined current work ability and musculoskeletal or respiratory conditions were significantly associated with claims where each of these outcomes may contribute to the other. Identified factors could be used to select subgroups of dairy farmers with either elevated or reduced risk of claims. Prevention of adverse health outcomes could be most effective when targeted to farmers at highest risk of occupational injury and disease.

Overview Psychosocial occupational epidemiology has mainly focused on the demand-control and, to a much lesser extent, the effort-reward-imbalance (ERI) models. These models and the strong focus on them raise some conceptual and methodological issues we will address in the following letter. The conceptual issues include the empirical confirmation of the assumptions of these models, the extent to which the focus on the demand-control and ERI models is warranted, and whether the sub-dimensions of the scales in these models have common health effects. We argue that there is a lack of empirical approval of (i) the assumptions behind both models and (ii) the focus on these models. The methodological issues include how exposure to job strain is categorized, how ERI previously has been measured, and the validity of self-reports of job strain. We argue that (i) a population independent definition of job strain is lacking, (ii) the older measurements of ERI mix exposure and effect, and (iii) we know little regarding the validity of the measurement of the psychosocial working environment. Finally, we suggest that analyses of monitoring data with a broader focus on the psychosocial working environment can be used to shed light to some of the issues raised above. Introduction In the last three decades (1, 2), psychosocial occupational epidemiology related to coronary heart disease (CHD) has mainly focused on the job-strain model, also referred to as the demand-control model (3, 4). In this model, two aspects of work are deemed relevant: demands and control. Negative consequences to health are to be expected when high demands are simultaneously present with low control. This combination has been termed job strain (3, 4). Recently, there has also been increased interest in the ERI model (5, 6) which considers the level of effort relative to rewards at work: an imbalance is present when the efforts outweigh the rewards (5, 6). In longitudinal studies of CHD, there has been only a

In patients with congenital heart disease (CHD), the association between supraventricular tachycardia (SVT), type of pathophysiology, and therapeutic interventions in a population-based cohort warrants further examination. A retrospective, longitudinal 15-year data set (1996-2010) was analyzed. Inclusion criteria included age ≤17 years, enrolled in South Carolina State Medicaid, and diagnosed as having one or more CHDs as well as SVT. SVT was diagnosed in 6.5 % of CHD patients (N = 1,169) during the 15-year epoch investigated. SVT was less likely to occur in African-American (hazard ratio [HR] = 0.76) or male patients (HR = 0.88), but it was significantly more likely to occur in patients age ≤12 months or in adolescents ≥13 years in those undergoing multiple surgeries/medical interventions for their CHD (HR = 1.14), those receiving antiarrhythmic/diuretic/preload-/afterload-reducing medications (HR = 5.46), and those with severe/cyanotic CHDs (HR = 1.52) or chromosomal abnormalities (HR = 1.64). Children who had an atrial septal defect secundum (adjusted odds ratio [aOR] = 3.03) and those treated with diuretic or antiarrhythmic medication (aOR = 1.80) were significantly more likely to undergo SVT ablation, whereas those with late-onset pulmonary hypertension (ages 6-12 years old) were significantly less likely to undergo SVT ablation. SVT recurred in only 14 of 166 patients who underwent SVT ablation. Multiple medical interventions at an early age may increase the risk of SVT occurrence in young CHD patients regardless of the severity/complexity of the CHD.

Asymptomatic carriage of gastrointestinal zoonoses is more common in people whose profession involves them working directly with domesticated animals. Subclinical infections (defined as an infection in which symptoms are either asymptomatic or sufficiently mild to escape diagnosis) are important within a community as unknowing (asymptomatic) carriers of pathogens do not change their behaviour to prevent the spread of disease; therefore the public health significance of asymptomatic human excretion of zoonoses should not be underestimated. However, optimal strategies for managing diseases where asymptomatic carriage instigates further infection remain unresolved, and the impact on disease management is unclear. In this review we consider the environmental pathways associated with prolonged antigenic exposure and critically assess the significance of asymptomatic carriage in disease outbreaks. Although screening high-risk groups for occupationally acquired diseases would be logistically problematical, there may be an economic case for identifying and treating asymptomatic carriage if the costs of screening and treatment are less than the costs of identifying and treating those individuals infected by asymptomatic hosts.

The aim of this review is to show the importance of occupational therapy/hand therapy for chronic graft-versus-host-disease (GVHD) patients and to outline the current state of the literature. GVHD of the hand can cause functional loss, reduced activities of daily life, poor social interaction, and loss of income because of limitations in work. Hand therapy, which is a specialty practised by both occupational therapists and physical therapists, has been proven to be an effective approach for hand-related musculoskeletal disorders; however, the literature search suggests that it is an underutilized specialty around the world. An electronic search was performed from 1997 to 2017 using OneFile (GALE), Medline/PubMed (NLM), Scopus (Elsevier), Science Citation Index Expanded (Web of Science), ProQuest Central (New), ProQuest Hospital Collection, Health Reference Center Academic (Gale), Health Research Premium Collection, Science Direct Journals (Elsevier), ProQuest Health & Medical Complete, Medical Database, Wiley Online Library, and SciTech Premium Collection for the period from 1994 to April 2017. Only randomized-controlled trials involving occupational therapy or hand therapy in patients with chronic hand GVHD were included in the final analysis. The search was limited to articles in English. Two reviewers independently assessed the methodological quality and extracted the data. The JADAD scoring method was used to score the articles. After the duplicates were excluded, 5466 articles were identified by the electronic database search for screening, out of which 5465 articles were excluded after reviewing. One article was further excluded on obtaining the full text as it was a case study. Hand therapy specialty, although a vital part of the recovery process for the patients with hand GVHD, is an underutilized specialty and well-designed trials are urgently needed for musculoskeletal hand GVHD, especially for focused hand therapy interventions.

This chapter deals with the estimation of occupancy as a state variable to assess the status of, and track changes in, species distributions when sampling with camera traps. Much of the recent interest in occupancy estimation and modeling originated from the models developed by MacKenzie et al. (2002, 2003), although similar methods were developed independently (Azuma et al. 1990; Bayley and Petersen 2001; Nichols and Karanth, 2002; Tyre et al. 2003), all of which deal with species occurrence information and imperfect detection. Less than a decade after these publications, the modeling and estimation of species occurrence and occupancy dynamics have increased significantly. Special features of scientific journals have explored innovative uses of detection–nondetection data with occupancy models (Vojta 2005), and an entire volume has synthesized the use and application of occupancy estimation methods (MacKenzie et al. 2006). Reviews of the topical concepts, philosophical considerations, and various sampling designs that can be used for occupancy estimation are now readily available for a range of audiences (MacKenzie and Royle 2005; MacKenzie et al. 2006; Bailey et al. 2007; Royle and Dorazio 2008; Conroy and Carroll 2009; Kendall and White 2009; Hines et al. 2010; Link and Barker 2010). As a result, it would be pointless here to recast all that these publications have so eloquently articulated, but that said, a review of any scientific topic requires sufficient context and relevant background information, especially when relatively new methodologies and techniques such as occupancy estimation and camera traps are involved. This is especially critical in a digital age where new information is published at warp speed, making it increasingly difficult to stay abreast of theoretical advances and research developments.

Infrared imaging has been used to visualize superficial temperatures in industrial employers standing and working in an indoor environment at 22°C. Temperature distributions and changes have been recorded digitally and analyzed. Mean skin temperatures determined by this method have been compared with superficial temperatures obtained with a probe thermocouple. During working hours, surface temperatures were higher over extensor muscles than over other structures and their spatial distributions differed dramatically from those observed before working hours. The authors also analyzed the cold water immersion of the hands during work. This paper showed that working generates different thermal effects on human skin that reflect physiological and pathological occupational conditions and can be monitored by infrared imaging.

We hypothesize that the occurrence of metabolic acidosis correlates with the cumulative rate of gastrointestinal (GI) illness and that incorporating acidosis surveillance would improve models used for the early detection of outbreaks of GI disease. We conducted a retrospective cohort study of consecutive patients seen in an urban pediatric tertiary care center from September 1995 to August 2005. All data were analyzed for correlation between acidosis and GI syndrome and for internal periodicities. Four years of data were used to create a model, and the first 100 days of 2004 were used for forecasting. Data collected included visit date, chief complaint (CC), International Classification of Diseases, 9th Revision, diagnoses (Dx), and limited laboratory data. Gastrointestinal syndrome was defined by either CC or Dx. Acidosis was defined as HCO₃ levels 19 mmol/dL or less. Exclusion criteria included hyperglycemia (glucose level >120 mg/dL), glycusoria, or having a test for glycosylated hemoglobin ordered. A simple regression model was used to measure correlation between rates of acidosis and GI_Dx and GI_CC. For acidosis and GI syndrome, we fitted a time series model to the daily data with an auto-regressive integrated moving average (1,1) error term. During the study period, there were 505,028 emergency department visits. The median age was 5.1 years (interquartile range, 1.6-11.8 years), and 46% of patients were females. Of these, 132,142 had GI_Dx and 136,304 had GI_CC. Blood chemistries were obtained from 91,052 patients (18.1%). Acidosis was detected in 32.4% of patients who had these laboratory tests sent.Periodicities were detected for GI_Dx, GI_CC, acidosis rates affected by day of the week, and seasonality, with no changes in incidence during the years of our study. Acidosis rates highly correlated with rates of GI syndrome on a daily basis (Pearson correlation coefficient, r = 0.66 for GI_Dx and r = 0.68 for GI_CC, P metabolic acidosis has a 42.2% positive

We describe the results of a systematic review of the literature on occupational therapy–related interventions for people with Parkinson’s disease (PD). Three broad categories of intervention emerged: (1) exercise or physical activity; (2) environmental cues, stimuli, and objects; and (3) self-management and cognitive–behavioral strategies. Moderate to strong evidence exists for task-specific benefits of targeted physical activity training on motor performance, postural stability, and balance. Low to moderate evidence indicates that more complex, multimodal activity training supports improvement in functional movement activities. The evidence is moderate that the use of external supports during functional mobility or other movement activities has positive effects on motor control. In addition, moderate evidence is available that individualized interventions focused on promoting participant wellness initiatives and personal control by means of cognitive–behavioral strategies can improve targeted areas of quality of life. The implications for practice, education, and research are discussed. PMID:24367954

Exercise and home modifications are effective interventions for preventing falls. Chronic disease management (CDM) items are one way for general practitioners (GPs) to access these interventions. This study aimed to evaluate the outcomes and feasibility of using CDM items for occupational therapy (OT) and physiotherapy (PT) sessions to address falls risk. A pre-post pilot study design was used to evaluate five collaborative sessions shared by a private OT and PT using CDM items and a GP management plan. Pre and post intervention measures were used to evaluate outcomes for eight patients aged ≥75 years from two GP practices. At 2 months post-intervention there were significant improvements in everyday functioning (P = 0.04), physical capacity (P = 0.01) and falls efficacy (P =0.01). Adherence to the intervention was excellent. Falls prevention interventions can be effective in primary care settings and sustainable pathways need to be developed to ensure access for older people at risk.

Full Text Available Cactus forage (Opuntia ficus-indica Mill., intensely cultivated in dry regions of northeast Brazil, although well adapted to the harsh semi-arid climate is affected by major problems such as pests and diseases, responsible for significant losses in production. This study aimed to investigate the occurrence and diversity of the etiologic agents of diseases of cactus cultivated in 38 municipalities in the semi-arid region of Paraiba. The analyses were conducted and processed at the Laboratory of Phytopathology of the Centro de Ciências Agrárias da Universidade Federal da Paraíba, in Areia – PB. Starting from sick cladodes isolations, multiplications and identifications of the found microorganisms were made. The identification of the microorganisms was achieved through observations of the macro and micromorphological characteristics of the cultures and tests of Gram and pathogenicity. Great incidence and diversity of microorganisms was verified in the cacti researched, but the highest occurrence was mainly that of fungus. The fungi of widest occurrence were: Scytallidium lignicola, Alternate tenuis, Macrophomina phaseolina, Cladosporium cladosporides, Lasiodiplodia theobromae, Fusarium oxysporum f. sp. opuntiarum, Curvularia lunata, Aspergillus niger, Nigrospora sphaerica, Colletotrichum gloeosporioides, Exserohilum turcicum, Pestalotia pitospora, Rhizopus stolonifer, Rhizoctonia solani and Sphaceloma protearum. A bacterium was also detected that was suspected to belong to the Erwinia sp. strain. Satisfaction of the Postulates of Koch proved the infectious nature of the detected microorganisms. High occurrence of the fungus S. lignicola, an agent of scale rot disease in 100% of the places researched, was observed. This fact is of great concern, since the progression of the disease can cause significant losses in production.

Domestic dogs and cats are potentially effective sentinel populations for monitoring occurrence and spread of Lyme disease. Few studies have evaluated the public health utility of sentinel programmes using geo-analytic approaches. Confirmed Lyme disease cases diagnosed by physicians and ticks submitted by veterinarians to the West Virginia State Health Department were obtained for 2014-2016. Ticks were identified to species, and only Ixodes scapularis were incorporated in the analysis. Separate ordinary least squares (OLS) and spatial lag regression models were conducted to estimate the association between average numbers of Ix. scapularis collected on pets and human Lyme disease incidence. Regression residuals were visualised using Local Moran's I as a diagnostic tool to identify spatial dependence. Statistically significant associations were identified between average numbers of Ix. scapularis collected from dogs and human Lyme disease in the OLS (β=20.7, PLyme disease. Findings reinforce the utility of spatial analysis of surveillance data, and highlight West Virginia's unique position within the eastern United States in regards to Lyme disease occurrence.

In sub-Saharan Africa, infectious diseases and malnutrition constitute the main health problems in children, while adolescents and adults are increasingly facing cardio-metabolic conditions. Among adolescents as the largest population group in this region, we investigated the co-occurrence of infectious diseases, malnutrition and cardio-metabolic risk factors (CRFs), and evaluated demographic, socio-economic and medical risk factors for these entities. In a cross-sectional study among 188 adolescents in rural Ghana, malarial infection, common infectious diseases and Body Mass Index were assessed. We measured ferritin, C-reactive protein, retinol, fasting glucose and blood pressure. Socio-demographic data were documented. We analyzed the proportions (95% confidence interval, CI) and the co-occurrence of infectious diseases (malaria, other common diseases), malnutrition (underweight, stunting, iron deficiency, vitamin A deficiency [VAD]), and CRFs (overweight, obesity, impaired fasting glucose, hypertension). In logistic regression, odds ratios (OR) and 95% CIs were calculated for the associations with socio-demographic factors. In this Ghanaian population (age range, 14.4–15.5 years; males, 50%), the proportions were for infectious diseases 45% (95% CI: 38–52%), for malnutrition 50% (43–57%) and for CRFs 16% (11–21%). Infectious diseases and malnutrition frequently co-existed (28%; 21–34%). Specifically, VAD increased the odds of non-malarial infectious diseases 3-fold (95% CI: 1.03, 10.19). Overlap of CRFs with infectious diseases (6%; 2–9%) or with malnutrition (7%; 3–11%) was also present. Male gender and low socio-economic status increased the odds of infectious diseases and malnutrition, respectively. Malarial infection, chronic malnutrition and VAD remain the predominant health problems among these Ghanaian adolescents. Investigating the relationships with evolving CRFs is warranted.

Healers provide support for acute and chronic illnesses in rural Mozambique, such as socially acceptable traditional 'vaccinations' (subcutaneous cuts in the skin to rub herbs directly into the bloody lesion). We aimed to document the frequency of blood exposure by traditional practitioners in Mozambique. We conducted surveys with a simple random sample of 236 traditional healers in Zambézia province. Chi-square and Wilcoxon rank-sum tests were used to compare 'injection' behaviours across districts. Healers treated a median of eight patients in the past month (IQR: 4-15). About 75% conducted 'injections'. These healers 'injected' a median of four patients (IQR: 1-8), used a new razor a median of three times (IQR: 1-8), and almost never used gloves. Lifetime blood exposures among those who provided 'injections' during treatments were estimated to be 1758 over a healer's career. The majority of healers are exposed repeatedly to patient blood. Given the high prevalence of HIV, hepatitis B and C virus, and other blood-borne agents, specific healer practices are an occupational hazard and reuse of razors is risky for their clients. © 2016 John Wiley & Sons Ltd.
Full Text Available There is mounting evidence for associations between sedentary behaviours and adverse health outcomes, although the data on occupational sitting and mortality risk remain equivocal. The aim of this study was to determine the association between occupational sitting and cardiovascular, cancer and all-cause mortality in a pooled sample of seven British general population cohorts.The sample comprised 5380 women and 5788 men in employment who were drawn from five Health Survey for England and two Scottish Health Survey cohorts. Participants were classified as reporting standing, walking or sitting in their work time and followed up over 12.9 years for mortality. Data were modelled using Cox proportional hazard regression adjusted for age, waist circumference, self-reported general health, frequency of alcohol intake, cigarette smoking, non-occupational physical activity, prevalent cardiovascular disease and cancer at baseline, psychological health, social class, and education.In total there were 754 all-cause deaths. In women, a standing/walking occupation was associated with lower risk of all-cause (fully adjusted hazard ratio [HR] = 0.68, 95% CI 0.52-0.89 and cancer (HR = 0.60, 95% CI 0.43-0.85 mortality, compared to sitting occupations. There were no associations in men. In analyses with combined occupational type and leisure-time physical activity, the risk of all-cause mortality was lowest in participants with non-sitting occupations and high leisure-time activity.Sitting occupations are linked to increased risk for all-cause and cancer mortality in women only, but no such associations exist for cardiovascular mortality in men or women.

This study has researched the significance of histologically raised findings and lung dust analyses in the context of claiming the recognition of and thus compensation for an asbestos-associated occupational disease. For this approach, all findings from the German Mesothelioma Register in 2015 that included lung dust analyses were evaluated and were compared with information on asbestos fiber exposure at work based on fiber years, and with the results of radiological findings. For 68 insured persons, recognition of an asbestos-induced lung disease according to Section 4104 of the German Ordinance on Occupational Diseases (Berufskrankheitenverordnung - BKV) could be recommended solely on the basis of the histological examinations of lung tissues and complementary lung dust analyses. Neither did the calculation of the cumulative asbestos dust exposure at work yield 25 fiber years, nor could bridge findings (e.g., plaques) be identified. In addition, the autopsies of 12 patients revealed plaques that had not been diagnosed during radiological examinations. These results show that - irrespective of the prescribed working techniques and radiological diagnosis - pathological/anatomical and histological diagnostics are often the only way for the insureds to demonstrate the causal connection between asbestos and their disease. Even after long intervals of up to 40 years post last exposure, the asbestos fibers would still be easily detectable in the lung tissues evaluated. Whenever suitable tissue is available, it should be examined for mild asbestosis with the aid of a lung dust analysis. Otherwise there is a risk that an occupational disease is wrongfully rejected. In the context of health insurance, the lung dust analysis and the resulting proof of the presence of asbestosis often constitute one option of providing evidence of an occupational disease.

A Sentinel Health Event (SHE) is a preventable disease, disability, or untimely death whose occurrence serves as a warning signal that the quality of preventive and/or therapeutic medical care may need to be improved. A SHE (Occupational) is a disease, disability, or untimely death which is occupationally related and whose occurrence may: (1) provide the impetus for epidemiologic or industrial hygiene studies; or (2) serve as a warning signal that materials substitution, engineering control, personal protection, or medical care may be required. The present SHE(O) list encompasses 50 disease conditions that are linked to the workplace. Only those conditions are included for which objective documentation of an associated agent, industry, and occupation exists in the scientific literature. The list will serve as a framework for developing a national system for occupational health surveillance that may be applied at the state and local level, and as a guide for practicing physicians caring for patients with occupational illnesses. The list will be updated periodically to accommodate new occupational disease events which meet the criteria for inclusion. 190 references, 1 figure, 1 table

Full Text Available El objetivo de este artículo es propiciar una reflexión -focalizada en los profesionales de la salud laboral- sobre el incremento en nuestro medio de la patología tropical, entre las que se incluye aquellas enfermedades que dejaron de ser endémicas en nuestro entorno y/o que nunca estuvieron presentes y que en la actualidad sin embargo, pueden verse cada vez más en las consultas médicas generales. Este tipo de enfermedades las conocemos con las denominaciones de enfermedades tropicales, importadas, emergentes o re-emergentes. El punto de partida es llamar la atención sobre si dichos profesionales tienen presente estos riesgos y si hacen un control o un seguimiento del estado de salud del trabajador antes del comienzo y al regreso, de la estancia ó del viaje. Adicionalmente otro asunto a tratar, son las consecuencias legales que llevan al trabajador a enfrentarse a estas patologías, bien por necesidad ó imperativo de la empresa donde trabajan, bien de forma voluntaria, si se trata del destino elegido por motivo de vacaciones.The aim of this paper is to propose a discussion about the increase of tropical pathologies, related with labour health workers, including new pathologies and other diseases that no longer were endemic in our society and now have become more frequent in our medical consulting rooms. These types of diseases are known as tropical or imported diseases, as well as emerging or re-emerging diseases. Our first point is about the attention paid by these health professionals on these risks and whether they really control and monitoring these diseases before and after the workers travel. Another issue are the legal consequences face by the workers that have to be exposed to theses diseases, either by requirement for their job companies or by their own choice on holiday´s destination.

To investigate whether influence at work modifies the association between demanding and strenuous occupational physical activity (OPA) and risk of ischaemic heart disease (IHD). A sample of 12,093 nurses aged 45-64 years from the Danish Nurse Cohort Study was followed for 20.6 years by individual linkage to incident IHD in the Danish National Patient Registry. Information on OPA, influence at work, other occupational factors and known risk factors for IHD was collected by self-report in 1993. During follow-up 869 nurses were hospitalised with incident IHD. Nurses exposed to strenuous OPA and low influence at work had a 46% increased risk of IHD [hazard ratio (HR) 1.46 (95% confidence interval (CI) 1.02-2.09)] compared to the reference group of nurses with moderate OPA and high influence at work. Nurses exposed to strenuous OPA and high influence at work were not at an increased risk of IHD [HR 1.10 (95% CI 0.59-2.06)]. An additive hazards model showed there were 18.0 (95% CI -0.01 to 36.0) additional cases of IHD per 10,000 person years among nurses with strenuous OPA and low influence at work compared to nurses with moderate OPA and high influence at work. A detrimental additive interaction between strenuous OPA and low influence at work that could explain the additional cases of IHD among nurses with strenuous OPA and low influence at work was indicated. The findings suggest that high influence at work may buffer some of the adverse effects of strenuous OPA on risk of IHD.
The prevalences of these three zoonotic diseases are not negligible and information targeting the public is needed. Moreover, the results highlight the lack of standardised surveys among different European countries. It was also noted that epidemiological data on leptospirosis are very scarce.

Pelvic inflammatory disease (PID) is a major cause of gynaecological morbidity globally. Complications from PID include infertility, ectopic pregnancy and chronic pelvic pain. Low socioeconomic status (SES) is a risk factor for the occurrence of PID. The aim of this study was to determine the association between SES of parents and the occurrence of PID among undergraduates attending Irrua Specialist Teaching Hospital, Irrua. The study was a hospital-based, descriptive cross-sectional study. Three hundred and sixty female undergraduates attending the hospital were consecutively recruited and clinically assessed for the presence of PID using the WHO and CDC MMWR 2010 criteria for the clinical assessment of PID. Their SES was determined by Oyedeji social class categorisation. Data were analysed using Epi Info 3.5.4. Descriptive statistics were used to summarise the data, and Chi-square was used to test for association. There was a significant association between SES of parents and multiple sex partners (P < 0.02), previous sexually transmitted infection (STI) (P = 0.05), unprotected sex (P < 0.001), history of induced abortion (P < 0.001) and surgical termination of pregnancy (P < 0.01). There was also association between occurrence of PID among respondents and multiple sexual partners (P < 0.001), previous history of STI (P = 0.02), non-persistent use of condom (P < 0.001), history of induced abortion (P < 0.01) and surgical termination of pregnancy (P < 0.01). There was however no significant association between SES of parents and occurrence of PID (P = 0.14) though PID was highest among respondents from low SES. Occurrence of PID among undergraduates was not associated with their SES. However, identified risk factors for PID among study population such as multiple sex partners, previous STI, unprotected sex and history of induced abortion were associated with the SES.

To understand the etiology of exposure-related diseases and to establish standards for reducing the risks associated with working in contaminated environments, the exact nature of the bioaerosol components must be defined. Molecular biology tools were used to evaluate airborne bacterial and, for the first time, archaeal content of dairy barns. Three air samplers were tested in each of the 13 barns sampled. Up to 10(6) archaeal and 10(8) bacterial 16S rRNA genes per m(3) of air were detected. Archaeal methanogens, mainly Methanobrevibacter species, were represented. Saccharopolyspora rectivirgula, the causative agent of farmer's lung, was quantified to up to 10(7) 16S rRNA genes per m(3) of air. In addition, a wide variety of bacterial agents were present in our air samples within the high airborne bioaerosol concentration range. Despite recommendations regarding hay preservation and baling conditions, farmers still develop an S. rectivirgula-specific humoral immune response, suggesting intense and continuous exposure. Our results demonstrate the complexity of bioaerosol components in dairy barns which could play a role in occupational respiratory diseases.

Lyme borreliosis is rapidly emerging in Canada, and climate change is likely a key driver of the northern spread of the disease in North America. We used field and modeling approaches to predict the risk of occurrence of Borrelia burgdorferi, the bacteria causing Lyme disease in North America. We combined climatic and landscape variables to model the current and future (2050) potential distribution of the black-legged tick and the white-footed mouse at the northeastern range limit of Lyme disease and estimated a risk index for B. burgdorferi from these distributions. The risk index was mostly constrained by the distribution of the white-footed mouse, driven by winter climatic conditions. The next factor contributing to the risk index was the distribution of the black-legged tick, estimated from the temperature. Landscape variables such as forest habitat and connectivity contributed little to the risk index. We predict a further northern expansion of B. burgdorferi of approximately 250-500 km by 2050 - a rate of 3.5-11 km per year - and identify areas of rapid rise in the risk of occurrence of B. burgdorferi. Our results will improve understanding of the spread of Lyme disease and inform management strategies at the most northern limit of its distribution.

Objectives We conducted a systematic literature review to identify studies fulfilling good scientific epidemiological standards for use in meta-analyses of relevant risk factors for Parkinson's disease. Methods Our search identified 103 original publications on associations between work and Parkinson's disease. GRADE guidelines were used to ensure high scientific quality, and reliable guidelines were applied to classify the papers. Of the 103 articles, 47 fulfilled good scientific standards while 56 were methodologically deficient and thus excluded from our meta-analyses. Results A total of 23 publications concerned work exposure to pesticides. The weighted relative risk estimate was 1.67 (95% confidence interval 1.42-1.97). A funnel plot and bias test indicated that some publication bias concerning smaller studies might have been present. The risk estimate was not influenced by study design (case-control, cohort, or cross-sectional study) or gender. Higher estimates were found when there was a hereditary taint or onset below age 60. Studies on exposure to metals or electromagnetic fields did not show increased risk. Conclusions Using an elaborated quality protocol, there is now strong evidence that exposure to any pesticide involves a ≥50% increased risk for developing Parkinson's disease.

Personalized pulmonary rehabilitation including occupational therapy improves the prognosis of patients with advanced COPD. We previously reported that patients with chronic obstructive pulmonary disease (COPD) exhibit three exercise-induced life-threatening conditions: hypoxemia, sympathetic overactivity, and respiratory acidosis. We aimed to verify whether mortality in patients with advanced COPD could be reduced by a personalized pulmonary rehabilitation (PPR) program in hospital, which determines individual safe ranges and includes occupational therapy (PPR-OT), to prevent desaturation and sympathetic nerve activation during daily activities. The novel PPR-OT program was evaluated in a retrospective study of patients with COPD (Global Initiative for Chronic Obstructive Lung Disease [GOLD] Grade D) who underwent cardiopulmonary exercise testing (CPET) between April 1990 and December 1999. They received regular treatment without the proposed therapy (control group: n=61; male-to-female ratio [M:F] =57:4; mean age: 68.5±6.7 years) or with the proposed therapy (PPR-OT group: n=46; M:F =44:2; mean age: 68.7±7.1 years). A prospective observational study included patients with COPD receiving home oxygen therapy (HOT) between April 1995 and March 2007 to compare the survival rates of the control group (n=47; M:F ratio =34:13; mean age: 71.3±10.0 years) and the PPR-OT group (n=85; M:F =78:7; mean age: 70.7±6.1 years) who completed the proposed therapy. Survival after CPET or HOT was analyzed using Cox proportional-hazards regression and Kaplan-Meier analyses. In both studies, the program significantly improved all-cause mortality (retrospective study: risk ratio =0.389 [range: 0.172-0.800]; P=0.0094; log-rank test, P=0.0094; observational study: risk ratio =0.515 [range: 0.296-0.933]; P=0.0291; log-rank test, P=0.0232]. At 5 years and 7 years, all-cause mortality was extremely low in patients in the PPR-OT group receiving HOT (18.8% and 28.2%, respectively

Full Text Available Abstract Background Seafarers play an important role in the transmission of communicable diseases. The aim of the present study is to draw information and identify possible gaps on occupational health practices related to seafarers sailing on ships within the European Union Member States (EU MS with focus on communicable diseases. Methods A structured questionnaire was sent to competent authorities from 21 EU MS. The questionnaire included questions about occupational health policies, medical certification of seafarers, communicable diseases reporting and relevant legislation. Descriptive analysis of the data was conducted by the use of Epi Info software: EU MS were categorized in four priority groups (A, B, C, D based on: number of passenger ships visits, volume of passengers, and number of ports in each country. Moreover, EU MS were categorized to old and new, based on the date of entry in the EU. Results All 21 countries with relevant competent authorities responded to the questionnaire. The existence of specific national legislation/regulation/guidelines related to vaccination of seafarers was reported by three out of the 21 (14% responding authorities. Surveillance data of communicable diseases related to seafarers are collected and analyzed by 4 (19% authorities. Five out of 21 of the responding countries (24% reported that tuberculin test result is required for the issuance of seafarer's medical certificate while a great variety of medical examination is required for the issuance of this certificate among countries. Gaps on occupational health services focused on communicable diseases related to maritime occupation have been reported by 33% of the responding countries. Responding authorities from Group A and B had the highest percentage of reported gaps followed by groups C and D. Old MS reported a higher frequency regarding gaps on occupational health services in comparison to new MS. Conclusion Our results revealed heterogeneity

Results support previous conclusions that dogs are effective sentinel populations for monitoring risk of human exposure to Lyme disease. Findings reinforce the utility of spatial analysis of surveillance data, and highlight West Virginia’s unique position within the eastern United States in regards to Lyme disease occurrence.

The prevalence of celiac disease (CD) in patients with type 1 diabetes (T1D) has been reported to be 5-7 times higher than in the general population. Risk factors for co-occurrence of both diseases have not been entirely established. The aim of our study was to analyze possible impact of human leukocyte antigen (HLA) class I and killer cell immunoglobulin-like receptors (KIRs) on the co-occurrence of T1D and CD. We analyzed 67 patients with T1D, 68 patients with CD, 69 patients with both diseases (T1D+CD) and 130 controls. Statistical analysis was based on two tailed Fisher exact test with corrections for multiple testing. After stratification by DR3-DQ2, an association of HLA class I part of the COX haplotype (A1-B8-Cw7-DR3-DQ2) was not observed with each of the studied diseases separately, but it could be shown in case of the co-occurrence of T1D and CD. Only in the group of patients with coexisting diseases, the presence of HLA-C*07 (P = 8.65×10(-3) ) and HLA-B*08 (P = 0.03) but not HLA-A*01 increased the succeptibility. Our current data indicated that C*07, contributing C1 ligand (Pc = 3.67×10(-5) ) rather than B*08, that possesses no KIR ligand, could have an impact on the innate immunity rout of this susceptibility. The significant combination of C1-KIR2DL3 (Pc = 1.97×10(-4) ) observed in patients with coexisting diseases supports this hypotesis. Interestingly, no association was observed when C1 in combination with its stronger inhibitory receptor KIR2DL2 was investigated. Predominantly, weak inhibition in patients with coexisting T1D and CD could lead to a natural killer cell response, making them vulnerable for developing more than one autoimmune disease. © 2014 John Wiley & Sons A/S.

Injuries and diseases can significantly affect the creativity and artistic performance. The link between working conditions and artistic performance had been recognised as early as the medieval age. Physically demanding performance arts such as dance can sometimes result in injuries, illnesses, inability to perform, and even end artist's career. Dancers are exposed to specific risks and in need of specific medical care. Many dancers often stretch their physical capabilities and endurance and neglect their physical limitations. Their health problems include a number of work-related illnesses that range from stress and stage fright to metabolic and nutritional disorders. They also include musculoskeletal injuries due to overload training that are often the beginning of chronic health problems.
Occupational risks to radiation workers are compared with other occupational risks on the basis of lost life expectancy (LLE) in a full working lifetime. Usual comparisons with National Safety Council accident death statistics for various industry categories are shown to be unfair because the latter average over a variety of particular industries and occupations within each industry. Correcting for these problems makes some common occupations in some industries 20-50 times more dangerous due to accidents alone than being a radiation worker. If more exposed subgroups of radiation workers are compared with more dangerous subgroups of other occupations, these ratios are maintained. Since radiation causes disease rather than acute injury, a wide range effort is made to estimate average loss of life expectancy from occupational disease; the final estimate for this is 500 days. The average American worker loses more than an order of magnitude more life expectancy from occupational disease than the average radiation worker loses from radiation induced cancer. (author)

Objective: To analyze the status of personnel in occupational disease prevention and treatment institutions in Hunan Province, China, from 1996 to 2015, to predict staff composition using grey model (GM) (1, 1) , and to provide a scientific basis and reference for optimizing human resource planning of occupational disease prevention and treatment in other provinces and regions and promoting the service capacity of the institutions. Methods: The data of the staff in occupational disease prevention and treatment institutions in Hunan Province, China, from 1996 to 2015 were obtained from the established basic information management system. The descriptive analysis method was used to analyze the dynamic changes in number and composition of the staff and the GM (1, 1) was used to predict the staff composition. Results: The numbers of the staff members in 1996 and 2015 in occupational disease prevention and treatment institutions in Hunan Province, China were 1591 and 1429, respectively. In the twenty years, the main education level of the staff transformed from "technical secondary school education and non-academic qualifications" to "bachelor degree or above and college degree"; the main major of the staff transformed from "other majors" to "public health and clinical medicine"; the proportion of the staff members without professional titles changed from >1/3 to 5%; and the proportions of the staff members with senior, intermediate, and junior professional titles were steadily rising. GM prediction showed that the proportions of highly educated staff members in 2018 and 2020 would be up to 41.00% and 45.61%, respectively; and the proportions of the staff members with a major in public health in 2018 and 2020 would be up to 44.15% and 46.60%, respectively. Conclusion: The staff in occupational disease prevention and treatment institutions in Hunan Province, China, in the twenty years have slight changes in staff size and great improvement in staff quality, which is

In this study the incidence risk of lower extremity arterial disease (LEAD; international classification of diseases version 9 code 440.2) was assessed in a cohort of workers occupationally exposed to radiation over a prolonged period. The study cohort includes 22,377 workers of the Mayak Production Association (25 % of whom are females) first employed at one of the main facilities in 1948-1982 and followed up to the end of 2008. Dose estimates used in the study are provided by Mayak Worker Dosimetry System 2008. The mean total dose from external gamma-rays is 0.54 Gy for males and 0.44 Gy for females. The mean absorbed liver dose from internal alpha-radiation due to incorporated plutonium is 0.23 Gy in males and 0.44 Gy in females. Relative risks and excess relative risks per unit dose (ERR/Gy) are calculated based on maximum likelihood. A total of 943 cases of LEAD are registered in the study cohort during the follow-up of 512,801 person-years. A significant association of LEAD incidence with total dose from external gamma-rays (based on a linear model) was revealed, and the ERR/Gy is 0.27 (95 % confidence interval (CI) 0.11; 0.48). It turned out that a linear-exponential model provides a better fit of the data (∇AIC = 9.957). Inclusion of an adjustment for internal alpha-radiation dose resulted in the reduction of the ERR/Gy to 0.19 (95 % CI 0.05; 0.39), but the risk remains significant. No association of LEAD incidence with dose from internal alpha-radiation was found in the study worker cohort. It is concluded that this study provides evidence for an association of LEAD incidence with dose from external gamma-rays taking non-radiation factors into account. (orig.)

The study of the regulation of occupations has a long and distinguished tradition in economics. In this paper, I present the central arguments and unresolved issues involving the costs and benefits of occupational licensing. The main benefits that are suggested for occupational licensing involve improving quality for those persons receiving the service. In contrast, the costs attributed to this labor market institution are that it restricts the supply of labor to the occupation and thereby dr...
Full Text Available Abstract This editorial is to announce the Journal of Occupational Medicine and Toxicology, a new Open Access, peer-reviewed, online journal published by BioMed Central. Occupational medicine and toxicology belong to the most wide ranging disciplines of all medical specialties. The field is devoted to the diagnosis, prevention, management and scientific analysis of diseases from the fields of occupational and environmental medicine and toxicology. It also covers the promotion of occupational and environmental health. The complexity of modern industrial processes has dramatically changed over the past years and today's areas include effects of atmospheric pollution, carcinogenesis, biological monitoring, ergonomics, epidemiology, product safety and health promotion. We hope that the launch of the Journal of Occupational Medicine and Toxicology will aid in the advance of these important areas of research bringing together multi-disciplinary research findings.

The objective of this study was to evaluate the effects of colostrum supplementation of the milk replacer ration on disease occurrence, antibiotic therapy, and performance of pre-weaned dairy calves with adequate transfer of passive immunity. Two hundred and two 1-d-old Holstein dairy calves were assigned to 1 of 2 groups after arrival to a dairy calf rearing facility. Calves assigned to the control group (n = 100) received milk replacer (28% crude protein and 20% crude fat) without colostrum inclusion twice daily. Calves assigned to the treatment group (n = 102) received 150 g of supplemental colostrum replacer powder added to their milk replacer twice daily for the first 14 d of life. Before group assignment, serum samples were collected from all calves to confirm transfer of passive immunity. Calves were evaluated daily until weaning (56 d of life) for signs of clinical disease as well as any treatment with antibiotics. Presentation of clinical disease and antibiotic treatment was recorded daily by personnel blinded to treatment allocation. Adequate transfer of passive immunity was confirmed in all calves at the start of the study and mean serum IgG values were similar among calves from treatment and control groups. The odds ratios of having abnormal feces and abnormal respiration during the pre-weaning period for calves from the treatment group were 0.15 and 0.46 the odds ratios of calves from the control group, respectively. The odds ratios of receiving antibiotic therapy during the pre-weaning period for calves from the treatment group were 0.09 the odds ratios of calves from the control group. Mean body weight and average daily gain at weaning were not significantly different among calves from the treatment and control groups. Colostrum replacer supplementation of the milk replacer ration was effective in reducing antibiotic therapy and occurrence of disease during the pre-weaning period.

Full Text Available The prevalence of contact dermatitis (CD in Europe varies between 6.7% and 10.6% depending on the sector of activity. Professional CD (PCD has an important economic impact − 30% of the budget compensation for occupational disease. In Romania, the prevalence of PCD is underestimated, with an even distribution of cases with respect to the allergic or irritative mechanism. A retrospective clinical study was conducted; target population being the patients admitted in Occupational Medicine Clinic Cluj-Napoca between 2003 and 2011. Objectives of study were: specifying the prevalence range of allergic CD (ACD / irritative CD (ICD among occupational/work-related diseases, the distribution of allergic/irritative CD (A/ICD for different sectors of activity and establishing the correlation between atopy and A/ICD. We have applied allergy skin tests - prick (environmental allergens and patch (occupational allergens. Inclusion criteria were: -documented occupational exposure at skin allergens/irritants; -the atopy state; -diagnostic established at discharge. Patients with recurrent chronic urticaria, angioedema, hypereosinophilic syndrome have been excluded. Statistical analysis was done using SPSS software. The study indicated a similar prevalence for A/ICD, with similar distribution. Prevalence above average has been recorded in the metallurgy sector (A/ICD, in health care sector (ACD, respectively, textile industry (ICD. The correlation atopy-ACD has proved to be lower compared to previous reports. Regarding ICD, the diagnostic was confirmed frequently to non-atopic persons. We strongly recommend the compliance with a multidisciplinary protocol for the management of A/ICD, individualized for specific activity sectors or even work stations.
The utilisation of data mining methods has become common in many fields. In occupational accident analysis, however, these methods are still rarely exploited. This study applies methods of data mining (decision tree and association rules) to the Finnish national occupational accidents and diseases statistics database to analyse factors related to slipping, stumbling, and falling (SSF) accidents at work from 2006 to 2007. SSF accidents at work constitute a large proportion (22%) of all accidents at work in Finland. In addition, they are more likely to result in longer periods of incapacity for work than other workplace accidents. The most important factor influencing whether or not an accident at work is related to SSF is the specific physical activity of movement. In addition, the risk of SSF accidents at work seems to depend on the occupation and the age of the worker. The results were in line with previous research. Hence the application of data mining methods was considered successful. The results did not reveal anything unexpected though. Nevertheless, because of the capability to illustrate a large dataset and relationships between variables easily, data mining methods were seen as a useful supplementary method in analysing occupational accident data.

Air pollution has been linked to an increased risk of ischemic heart disease (IHD), but less is known about occupational exposure to welding fumes and the risk of IHD. The objective of this paper was to review the epidemiological evidence on causal links between welding fume exposure and risk of IHD and to investigate whether the risk of IHD depends on specific welding characteristics. A systematic search in Medline 1979-2013 and EMBASE 1974-2013 identified 18 epidemiological studies with at least one risk estimate of IHD morbidity or mortality among workers exposed to welding fumes. Following an assessment of completeness of reporting, confounding, and bias, each risk estimate was characterized as more or less reliable. Pooled risk estimates were computed across studies by random effect meta-analyses. The weighted relative risk (RR) for IHD following exposure to welding fumes was 1.09 [95 % confidence interval (CI) 1.00, 1.19]. We calculated a RR of 1.39 (95 % CI 0.96, 2.02) among studies using an internal reference group and 1.08 (95 % CI 0.99, 1.18) for studies using an external reference group. An increased risk was observed for acute myocardial infarction RR = 1.69 (95 % CI 1.18, 2.42) and other IHDs RR = 1.06 (95 % CI 0.98, 1.14). There was too limited evidence to evaluate the risk of IHD related to specific welding characteristics. Several studies indicate that welding is associated with a moderately increased risk of IHD; however, bias and confounding cannot be ruled out with reasonable confidence.

Full Text Available O presente artigo é uma atualização sobre a ocorrência e diagnóstico das riquetsioses existentes no Brasil e Portugal, com o objetivo de incentivar e incrementar a vigilância epidemiológica dessas doenças nos dois países. Realizou-se levantamento bibliográfico e foram apresentados dados não publicados de laboratórios e serviços de epidemiologia. Os resultados descreveram a ocorrência das riquetsioses no Brasil e Portugal, inclusive aquelas recém-descritas, advindas de riquétsias de potencial patogênico ainda incerto. Os métodos diagnósticos atualmente empregados foram discutidos. Como em outros países, as riquetsioses parecem assumir crescente importância em saúde pública. Relegadas a um plano secundário por muitas décadas, o interesse por essas infecções tem aumentado nos dois países, mas ainda carece de investigação para esclarecer seu real significado em saúde pública.The present study is an update review on the occurrence and diagnosis of rickettsial diseases in Brazil and Portugal, aiming at promoting their epidemiological surveillance in both countries. A literature review was carried out and unpublished data of laboratories and surveillance systems were presented. The results described the occurrence of rickettsial diseases and infections in Brazil and Portugal, including other new and still poorly understood rickettsial infections. Current diagnostic methods were discussed. As in many other countries, rickettsial diseases and infections seem to be an emerging public health problem. Treated as a minor problem for many decades, the interest in these infections has increased in both countries but further studies are needed to establish their role as a public health problem.

The efficacy of umbilical cord blood transplantation (UCBT) as treatment for acute myeloid leukaemia (AML) relies on immune-mediated graft-versus-leukaemia effects. Previous studies have suggested a strong association between graft-versus-host disease (GVHD) occurrence and graft-versus-leukaemia effects after allogeneic hematopoietic cell transplantation. Here, we evaluated the kinetics of relapse rate in correlation with GVHD occurrence after UCBT. The kinetics of relapse rate over time in correlation to GVHD occurrence were assessed by calculating the relapse rate per patient-year within sequential 90-day intervals. The impact of GVHD on relapse and mortality was further studied in multivariate Cox models handling GVHD as a time-dependent covariate. The study included data from 1068 patients given single (n = 567) or double (n = 501) UCBT. The proportion of patients with grade II, III and IV acute GVHD was 20%, 7% and 4%, respectively. At 2 years, the cumulative incidence of chronic GVHD was 42%, the cumulative incidence of relapse was 32%, and overall survival was 32% as well. Relapse rates declined gradually over time during the first 30 months after transplantation. There was a possible suggestion that grade II-IV acute (HR = 0.8, P = 0.1) and chronic (HR = 0.65, P = 0.1) GVHD decreased relapse risk. However, grade II-IV acute GVHD significantly increased early (the first 18 months after UCBT) mortality (HR = 1.3, P = 0.02), whilst chronic GVHD increased each early (HR = 2.7, P chronic GVHD each increases overall mortality after UCBT for AML mitigating the possible graft-versus-leukemia effect of GVHD. © 2017 The Association for the Publication of the Journal of Internal Medicine.

In many Sub-Saharan African populations, in particular urban dwellers, there have been marked rises in the prevalences of obesity in women, hypertension, diabetes, and cerebral vascular disease. Yet there have been only slight rises in coronary heart disease. To learn more of the roles of the various influencing factors in the puzzling situations described, some aspects of the past and present occurrences of these diseases are described and discussed, with comparisons being made with corresponding situations in African Americans, as well as in certain white populations. Despite increases in the knowledge of influencing factors, such fail to explain fully the epidemiologic situations described. As to the future, judging from the experiences of other populations, despite continuing indigence, within the next generation significant rises in coronary heart disease in certain African populations seem to be inevitable. However, in many of those populations, in particular those in the South, the extent of changes, apart from those linked with level of socioeconomic state, will be strongly affected by the rising epidemic of human immunodeficiency virus and acquired immunodeficiency syndrome.

Occupational consciousness refers to ongoing awareness of the dynamics of hegemony and recognition that dominant practices are sustained through what people do every day, with implications for personal and collective health. The emergence of the construct in post-apartheid South Africa signifies the country's ongoing struggle with negotiating long-standing dynamics of power that were laid down during colonialism, and maintained under black majority rule. Consciousness, a key component of the new terminology, is framed from post-colonial perspectives - notably work by Biko and Fanon - and grounded in the philosophy of liberation, in order to draw attention to continuing unequal intersubjective relations that play out through human occupation. The paper also draws important links between occupational consciousness and other related constructs, namely occupational possibilities, occupational choice, occupational apartheid, and collective occupation. The use of the term 'consciousness' in sociology, with related or different meanings, is also explored. Occupational consciousness is then advanced as a critical notion that frames everyday doing as a potentially liberating response to oppressive social structures. This paper advances theorizing as a scholarly practice in occupational science, and could potentially expand inter or transdisciplinary work for critical conceptualizations of human occupation.

Background Failure to detect a disease agent or vector where it actually occurs constitutes a serious drawback in epidemiology. In the pervasive situation where no sampling technique is perfect, the explicit analytical treatment of detection failure becomes a key step in the estimation of epidemiological parameters. We illustrate this approach with a study of Attalea palm tree infestation by Rhodnius spp. (Triatominae), the most important vectors of Chagas disease (CD) in northern South America. Methodology/Principal Findings The probability of detecting triatomines in infested palms is estimated by repeatedly sampling each palm. This knowledge is used to derive an unbiased estimate of the biologically relevant probability of palm infestation. We combine maximum-likelihood analysis and information-theoretic model selection to test the relationships between environmental covariates and infestation of 298 Amazonian palm trees over three spatial scales: region within Amazonia, landscape, and individual palm. Palm infestation estimates are high (40–60%) across regions, and well above the observed infestation rate (24%). Detection probability is higher (∼0.55 on average) in the richest-soil region than elsewhere (∼0.08). Infestation estimates are similar in forest and rural areas, but lower in urban landscapes. Finally, individual palm covariates (accumulated organic matter and stem height) explain most of infestation rate variation. Conclusions/Significance Individual palm attributes appear as key drivers of infestation, suggesting that CD surveillance must incorporate local-scale knowledge and that peridomestic palm tree management might help lower transmission risk. Vector populations are probably denser in rich-soil sub-regions, where CD prevalence tends to be higher; this suggests a target for research on broad-scale risk mapping. Landscape-scale effects indicate that palm triatomine populations can endure deforestation in rural areas, but become rarer in

To conduct a systematic literature review to identify social and occupational factors affecting the psychological wellbeing of healthcare workers involved in the severe acute respiratory syndrome (SARS) crisis. Four literature databases were searched and data extracted from relevant papers. Eighteen thousand five papers were found and 22 included in the review. The psychological impact of SARS on employees appeared to be associated with occupational role; training/preparedness; high-risk work environments; quarantine; role-related stressors; perceived risk; social support; social rejection/isolation; and impact of SARS on personal or professional life. To minimize the psychological impact of future outbreaks of infectious diseases, healthcare workers should be prepared for the potential psychological impact; employers should encourage a supportive environment in the workplace and ensure that support is in place for those most at risk, for example, those with the most patient contact.

Full Text Available Control of oral lesions contributes directly to the health, survival and welfare of captive animals. In order to investigate the occurrence of oral diseases in neotropical wild carnivores kept at the zoo at the Federal University of Mato Grosso – Cuiabá, we evaluated 31 oral cavities from three families of carnivores (Felidae, Canidae and Procyonidae between July 2012 and June 2013. Twelve coatis (Nasua nasua, three raccoons (Procyon cancrivorus, two maned wolves (Chrysocyon brachyurus, six crab-eating fox (Cerdocyon thous, one hoary fox (Pseudalopex vetulus, three ocelots (Leopardus pardalis, one cougar (Puma concolor and three wild cats (Puma yagouaroundi, Leopardus wiedii and Leopardus colocolo were reviewed. The most frequent lesions were dental absences 21/31 (67.7%, dental fractures 20/31 (64.5% and tooth wear 19/31 (61.3%, which were suggestive of trauma caused from stress. Of lesser importance, we also observed occurrence of dental calculus grade I in 18/31 (58%, caries 1/31 (3.2%, foreign bodies 2/31 (6.4%, orofacial fistulas 1/31 (3.2%, hyperplasia in the oral mucosa 1/31 (3.2%, dental dimming 3/31 (9.7% and chafing of the soft tissue 5/31 (16.1%. Therefore, it was concluded that environmental enrichment strategies and oral routine evaluation must be implemented to ensure the welfare of these animals, reducing local and systemic adverse effects of oral lesions. The diet has been successful in preventing periodontal disease, suggesting that this diet for the captive animals in the institution should be maintained.

To examine the site-specific cancer mortality among deaths registered with Parkinson's disease (PD) and multiple sclerosis (MS). We focused on the patterns related to the most frequent cancers. We analyzed Swiss mortality data over a 39-year period (1969-2007), using a statistical approach applicable to unique daabases, i.e. when no linkage with morbidity databases or disease registries is possible. It was based on a case-control design with bootstrapping to derive standardized mortality ratios (SMR). The cases were defined by the cancer-PD or cancer-MS co-registrations, whereas the controls were drawn from the remaining records with cancer deaths (matching criteria: sex, age, language region of Switzerland, subperiods 1969-1981, 1982-1994, 1995-2007). For PD we found lower SMRs in lung and liver cancer and higher SMRs in melanoma/skin cancer, and in cancers of breast and prostate. As for MS, the SMR in lung cancer was lower than expected, whereas SMRs in colorectal, breast and bladder cancer were higher. A common pattern of associations can be observed in PD and MS, with a lower risk of lung cancer and higher risk of breast cancer than expected. Thus, PD and MS resemble other conditions with similar (schizophrenia) or reversed patterns (rheumatoid arthritis, immunosuppression after organ transplantation). Copyright © 2016 Elsevier Ltd.

Moreover, many various types of disease symptoms, which were described and made a diagnosis. There were mainly spots on leaves and steams, from which there were isolated most often fungi from Alternaria genus. The investigations on the salubrity of the seed material (angelica fruits coming from different sources showed that fungi from genus Alternaria were likely to transfer by seeds and caused disease symptoms on plants during vegetation. Fungi from genus Alternaria were most often isolated from angelica fruits. Saprotrophic fungi (Epicoccum purpurascens, Penicillium spp., Mucor hiemalis were also often isolated from angelica fruits. Disinfection on fruits reduced number of isolated fungi and bacteria.
Full Text Available Due to increasing demand of medicinal plants (MPs, quality and safety more attention to the plant health should be paid. Among herb pathogens, especially fungi cause serious diseases in these plants decreasing yield and quality of herbal raw material. Some species, i.e. Fusarium sp., Alternaria sp., Penicillium sp. are known as mycotoxin producers. Paradoxically, self-treatment with herbal raw material can expose the patient to mycotoxin activity. In tissues of some MPs species, asymptomatically endophytic fungi residue. It is known that they are able to influence a biosynthesis of secondary metabolites in their host plant or produce biologically active compounds. Until recently these microorganisms have been neglected as a component of MPs, the reason why there have unexplored bioactivity and biodiversity. The paper presents an overview of herbal plants that are used in the treatment of nervous system diseases. Pathogenic fungi that infect these plants are described. It focused mainly on species producing harmful mycotoxins. The publication presents a list of these mycotoxins and a brief description of their effects on human health. The second part of this article provides information on the occurrence of endophytic fungi in herbal plants and their effects on human health. Coexistence of fungi and medicinal plants is not fully understood but can be crucial to ensure health and safety of patients with neurological diseases and mental disorders.

The use of wastewater for rearing domestic animals is a common phenomenon in most of the developing countries like Pakistan that face a serious shortage of freshwater resources. However, most of the literature has only focused on the indirect effects of wastewater use on animal health or productivity, and literature on the direct effects of wastewater use is rare. Therefore, this study aims to investigate the direct and indirect effects of wastewater usage on the prevalence of animal diseases and animal health in Pakistan. The study is based on a household-level survey of 360 domestic water buffalo herds collected from 12 districts of Punjab Province, Pakistan. We tested the prevalence of the animal's diseases, animal's health, and wastewater-use preference with various econometric tools, such as the Poisson, negative binomial, and logistic regressions. The findings of the study show that the majority of the farmers use wastewater for buffalo bathing due to the shortage of freshwater resources. Results explore the prevalence of diseases such as clinical mastitis, tick infestation, and foot and mouth disease at the farm level significantly associated with buffalo bathing in the wastewater. Moreover, bathing in wastewater pre- and post-milking also plays a role in the occurrence of diseases. Particularly, if the buffalo's access to wastewater for bathing is within 60 min after milking, the probability of the animals being exposed to mastitis is higher. Furthermore, on investigation, a number of factors are found, such as the distance to the water source, power shortage, groundwater availability, and the education of farmers that influence farmers' behavior of letting their animals take a bath in wastewater. Moreover, the use of different preventive measures improves the animal's health.

retrospective cohort study. The aim of this study was to determine the rate of revision surgery and the occurrence of adjacent segment disease of patients undergoing ACDF for cervical radiculopathy and myelopathy using more modern-day instrumentation techniques. Anterior cervical discectomy and fusion (ACDF) has long been the preferred treatment for cervical radiculopathy and myelopathy. All patients undergoing ACDF between January of 2000 and December of 2010 were included. Age, sex, height, weight, body mass index, symptoms at presentation, number of levels fused, graft type, and smoking status were recorded. Outcomes included revision rate, reason for revision surgery, time to revision surgery, presence and grade of adjacent segment disease, distance from the instrumentation to the cranial and caudal endplate (plate-to-disc distance), and reporting of symptoms of adjacent segment disease at the final follow-up. A total of 672 patients were included in this study. The average duration of follow-up was 31 months. One hundred one (15%) patients underwent revision surgery. The reason for revision surgery was adjacent segment disease in 47 (47.5%), pseudarthrosis in 45 (45.5%) and a new problem at a nonadjacent level in 7 (7.1%) of those patients. The need for revision surgery was not affected by patient age, sex, body mass index, smoking status, symptoms at presentation, number of levels fused, plate-to-disc distance or graft type. The revision rate after ACDF is 15%. Most revisions were done for either adjacent segment disease or pseudarthrosis. No specific risk factors for revision surgery were identified in this study. 3.

Higher levels of stress impact the prevalence of metabolic syndrome (MetS) and coronary heart disease. The association between MetS, impaired pulmonary function and low level of physical activity is still pending assessment in the subjects exposed to stress. The study aimed to examine whether higher levels of stress might be related to MetS and the plaque presence, as well as whether MetS might affect pulmonary function. The study embraced 235 police officers (mean age 40.97 years) from the south of Poland. The anthropometrics and biochemical variables were measured; MetS was diagnosed using the International Diabetes Federation criteria. Computed tomography coronary angiography of coronary arteries, exercise ECG, measurements of brachial flow-mediated dilation, and carotid artery intima-media thickness were completed. In order to measure the self-perception of stress, 10-item Perceived Stress Scale (PSS-10) was applied. Pulmonary function and physical activity levels were also addressed. Multivariate logistic regression analyses were applied to determine the relationships between: 1/ incidence of coronary plaque and MetS per se, MetS components and the number of classical cardiovascular risk factors, 2/ perceived stress and MetS, 3/ MetS and pulmonary function parameters. Coronary artery atherosclerosis was less associated with MetS (OR = 2.62, 95%CI 1.24-5.52; p = 0.011) than with a co-existence of classical cardiovascular risk factors (OR = 5.67, 95% CI 1.07-29.85, p = 0.03; for 3 risk factors and OR = 9.05; 95% CI 1.24-66.23, p = 0.02; for 6 risk factors, respectively). Perceived stress increased MetS prevalence (OR = 1.07, 95% CI 1.03-1.13; p = 0.03), and impacted coronary plaque prevalence (OR = 1.05, 95% CI 1.001-1.10; p = 0.04). Leisure-time physical activity reduced the chances of developing MetS (OR = 0.98 95% CI 0.96-0.99; p = 0.02). MetS subjects had significantly lower values of certain pulmonary function parameters.

In low-income countries, a growing proportion of the disease burden is attributable to non-communicable diseases (NCDs). There is little knowledge, however, of their impact on wealth, human capital, economic growth or household poverty. This article estimates the risk of being poor after an NCD death in the rural, low-income area of Matlab, Bangladesh. In a matched cohort study, we estimated the 2-year relative risk (RR) of being poor in Matlab households with an NCD death in 2010. Three separate measures of household economic status were used as outcomes: an asset-based index, self-rated household economic condition and total household landholding. Several estimation methods were used including contingency tables, log-binomial regression and regression standardization and machine learning. Households with an NCD death had a large and significant risk of being poor. The unadjusted RR of being poor after death was 1.19, 1.14 and 1.10 for the asset quintile, self-rated condition and landholding outcomes. Adjusting for household and individual level independent variables with log-binomial regression gave RRs of 1.19 [standard error (SE) 0.09], 1.16 (SE 0.07) and 1.14 (SE 0.06), which were found to be exactly the same using regression standardization (SE: 0.09, 0.05, 0.03). Machine learning-based standardization produced slightly smaller RRs though still in the same order of magnitude. The findings show that efforts to address the burden of NCD may also combat household poverty and provide a return beyond improved health. Future work should attempt to disentangle the mechanisms through which economic impacts from an NCD death occur. © The Author 2016. Published by Oxford University Press. All rights reserved.

Although tobacco smoke is the main risk factor for chronic obstructive pulmonary disease (COPD), other inhaled toxics have also been associated with the disease. The present study analyzes data from exposure to these substances in a cohort of patients with COPD and assesses their impact on the clinical presentation of the disease. This is a cross-sectional analysis of the Clinical presentation, diagnosis and course of chronic obstructive pulmonary disease (On-Sint) study. All patients were smokers or ex-smokers as per protocol. In addition, during the inclusion visit patients were enquired about their occupational and biomass exposure history. The clinical features of patients with and without an added risk factor to tobacco were compared and those significant were entered in a multivariate logistic regression analysis, expressed as odds ratio (OR). The sample size was 1214 patients with COPD, of which 1012 (83.4%) had tobacco as the only risk factor and 202 (16.6%) had additional ones, mainly 174 (14.3%) with occupational gases and 32 (2.6%) with biomass exposure. The geographical distribution of this exposure showed a preference for the northern parts of the country and the East coast. The biomass exposure was rather low. Male gender (OR: 2.180), CAT score (OR: 1.036) and the use of long-term oxygen therapy (OR: 1.642) were associated with having an additional risk factor in the multivariate analysis. Occupational exposures are more common than biomass in Spain. COPD caused by tobacco plus other inhalants has some differential features and a more impaired quality of life. Copyright © 2016 SEPAR.

Given the far-reaching changes of modern working life, psychosocial stress at work has received increased attention. Its influence on stress-related disease risks is analysed with the help of standardised measurements based on theoretical models. Two such models have gained special prominence in recent years, the demand-control model and the effort-reward imbalance model. The former model places its emphasis on a distinct combination of job characteristics, whereas the latter model's focus is on the imbalance between efforts spent and rewards received in turn. The predictive power of these models with respect to coronary or cardiovascular disease and depression was tested in a number of prospective epidemiological investigations. In summary, twofold elevated disease risks are observed. Effects on cardiovascular disease are particularly pronounced among men, whereas no gender differences are observed for depression. Additional evidence derived from experimental and ambulatory monitoring studies supplements this body of findings. Current scientific evidence justifies an increased awareness and assessment of these newly discovered occupational risks, in particular by occupational health professionals. Moreover, structural and interpersonal measures of stress prevention and health promotion at work are warranted, with special emphasis on gender differences.

In the period of transition from a centralized economy to the market economy, occupational health services in Kyrgyzstan have survived through dramatic, detrimental changes. It is common for occupational health regulations to be ignored and for basic occupational health services across many industrial enterprises and farms to be neglected. The aim of this study was to demonstrate the present situation and challenges facing occupational health services in Kyrgyzstan. The transition from centralized to the market economy in Kyrgyzstan has led to increased layoffs of workers and unemployment. These threats are followed by increased workload, and the health and safety of workers becomes of little concern. Private employers ignore occupational health and safety; consequently, there is under-reporting of occupational diseases and accidents. The majority of enterprises, especially those of small or medium size, are unsanitary, and the health status of workers remains largely unknown. The low official rates of occupational diseases are the result of data being deliberately hidden; lack of coverage of working personnel by medical checkups; incompetent management; and the poor quality of staff, facilities, and equipment. Because Kyrgyzstan is a mountainous country, the main environmental and occupational factor of enterprises is hypoxia. Occupational health specialists have greatly contributed to the development of occupational medicine in the mountains through science and practice. The enforcement of existing strong occupational health legislation and increased financing of occupational health services are needed. The maintenance of credible health monitoring and effective health services for workers, re-establishment of medical services and sanitary-hygienic laboratories in industrial enterprises, and support for scientific investigations on occupational risk assessment will increase the role of occupational health services in improving the health of the working population
-specific HRQoL improved in all IBD patients and at twelve months follow-up the majority of patients had a good disease-specific HRQoL score. Differences in how, and from whom, patients received disease-specific education and information were noted between the geographic regions; for instance IBD specialist...... nurses were not used in Eastern European IBD centres. Expenses for the cohort during the initial year of disease exceeded four million Euros with most money spent on diagnostics and surgery. Biological therapy accounted for one fourth costs in Western European CD patients. Long-term follow-up of the Epi...

We examined the relationship between cerebral amyloid angiopathy (CAA), Alzheimer’s disease neuropathologic changes (ADNC), other vascular brain pathologies, and cognition in a large multi-center autopsy sample. Data was obtained from the National Alzheimer’s Coordinating Center on autopsied subjects (N=3,976) who died between 2005 and 2012. Descriptive statistics and multivariable regression models estimated the associations between CAA and other pathologies, and between CAA severity and cognitive test scores proximal to death. CAA tended to co-occur with ADNC but a substantial minority of cases were discrepant. CAA was absent in 22% (n= 520) of subjects with frequent neuritic plaques but present in 20.9% (n=91) of subjects with no neuritic plaques. In subjects with no/sparse neuritic plaques, non-hemorrhagic brain infarcts were more common in those with CAA pathology than without (P= 0.007). In subjects without the APOE ε4 allele, CAA severity was associated with lower cognition proximal to death, factoring in other pathologies. The presence of CAA in non-AD patients may indicate a distinct cerebrovascular condition. PMID:26239176

Six subtypes of sporadic Creutzfeldt-Jakob disease with distinctive clinico-pathological features have been identified largely based on two types of the abnormal prion protein, PrP(Sc), and the methionine (M)/valine (V) polymorphic codon 129 of the prion protein. The existence of affected subjects showing mixed phenotypic features and concurrent PrP(Sc) types has been reported but with inconsistencies among studies in both results and their interpretation. The issue currently complicates diagnosis and classification of cases and also has implications for disease pathogenesis. To explore the issue in depth, we carried out a systematic regional study in a large series of 225 cases. PrP(Sc) types 1 and 2 concurrence was detected in 35% of cases and was higher in MM than in MV or VV subjects. The deposition of either type 1 or 2, when concurrent, was not random and always characterized by the coexistence of phenotypic features previously described in the pure subtypes. PrP(Sc) type 1 accumulation and related pathology predominated in MM and MV cases, while the type 2 phenotype prevailed in VVs. Neuropathological examination best identified the mixed types 1 and 2 features in MMs and most MVs, and also uniquely revealed the co-occurrence of pathological variants sharing PrP(Sc) type 2. In contrast, molecular typing best detected the concurrent PrP(Sc) types in VV subjects and MV cases with kuru plaques. The present data provide an updated disease classification and are of importance for future epidemiologic and transmission studies aimed to identify etiology and extent of strain variation in sporadic Creutzfeldt-Jakob disease.

Infections caused by Campylobacter spp. are now considered to be one of the most important foodborne diseases worldwide, this organism is one of the most epidemiologically significant zoonotic pathogens. Among these pathogens Campylobacter jejuni have the greatest epidemiological importance, they are responsible for 90% of laboratory confirmed cases of food campylobacteriosis. The frequency of detection of campylobacters in the environmental and on many raw foods, of both plant and animal origin, in normal intestine biota of domestic and wild animal and birds, indicates the prevalence of these bacteria and the high risk of contamination of food and water. The main factors of transmission in sporadic campylobacteriosis are the poultry and poultry products (up to 70% of the total number of cases), water (8%), raw milk (5%). One of the risk factors for the spread of emergent pathogen is its ability to persist in aquatic ecosystems. Continuing changes in landscape and agricultural intensification can cause further enhance microbial contamination of freshwater bodies and groundwater, and the associated increase in the number of cases of waterborne campylobacteriosis. Intensification of agriculture, expanding the range of applied disinfectants and antiseptics, uncontrolled use of antibiotics in livestock often leads to the selection of the sustainable strains of Campylobacter spp., which have antibiotic resistance and multiple virulence determinants. This paper presents an overview of modern methods for the detection of Campylobacter spp., detailed culture and biochemical methods for the isolation of C. jejuni based on the use of selective culture media and diagnostic kits for the characterization of the phenotypic profiles of the strains. These methods are the starting point in selecting the most effective schemes of food control and surveillance. It is emphasized that the basis of microbiological analysis should be molecular methods based on real-time PCR, which allows

The authors sought to explore the prevalence and factors related to nonalcoholic fatty liver disease (NAFLD) among occupational population in Taipei, Taiwan. A total of 8347 healthy adults voluntarily admitted to annual physical check-up. Blood samples and ultrasound-proved fatty liver sonography results were collected. The results showed that the prevalence of NAFLD was 48.4% and revealed a statistically significant increase with increasing population age. Males exhibited a greater prevalence of NAFLD than did females (57.8% vs 32.4%, P < .001). Using multiple logistic regression analysis, in addition to male gender, older age, higher body mass index, higher aspartate aminotransferase level, higher alanine aminotransferase level, presence of hypertension, presence of hyperuricemia, presence of hypercholesterolemia, higher fasting plasma glucose, and presence of hypertriglyceridemia were the significant factors associated with NAFLD. The differences in occupational professions were revealed. In conclusion, occupational populations are asymptomatic, and the diagnosis of NAFLD should be considered with older age, hyperuricemia, higher aspartate aminotransferase level, higher alanine aminotransferase level, and metabolic risk factors. © 2013 APJPH.

The aim of the study was to establish whether adiponectin may act as an independent risk factor of coronary artery disease (CAD) and if adiponectin has potential relations with a new marker of cardiovascular risk -intima-media thickness (IMT). 165 patients, who had undergone coronary angiography due to symptoms of CAD were enrolled. Selected clinical and biochemical risk factors were assessed, adiponectin concentrations and IMT were measured. A significantly lower adiponectin concentrations in the CAD group, as compared to the controls, were found. Adiponectin concentration did not correlate with a degree of coronary vessels changes advancement. No correlation between adiponectin concentrations and IMT values in the studied peripheral arteries were found. The value of 9.8 ug/ml has been assigned as a cut-off value. Adiponectin concentrations coronary artery disease occurrence, but not its advancement. No correlation between adiponectin concentration and IMT values in peripheral arteries was shown.

Species distribution models (SDMs), which are well established in many fields of biological research, are still uncommon in the agricultural risk analysis of pest insects. To exemplify the use of SDMs, we investigated the influence of environmental factors on the occurrence of Hyalesthes obsoletus Signoret (Hemiptera: Cixiidae). The planthopper is the only known vector of the grapevine yellows disease 'bois noir'. The study was conducted in 145 locations in the Baden region of southwest Germany. The planthopper was surveyed on host plant patches, consisting of stinging nettle and/or bindweeds. We used a stratified modelling framework where (1) species presence-absence data were related to an extensive environmental dataset using logistic regressions; and (2) different types of average models were developed based on an information theoretic method. The results show that the incidence of H. obsoletus is associated to above- as well as below-ground environmental factors, particularly to the amount of fine soil and average annual precipitation. This result was consistent across all average models. The relative importance of other environmental variables was dependent upon the average model under consideration and thus may vary according to their intended use, either the explanation of habitat requirements or the prediction and mapping of occurrence risks. The study showed that SDMs offer a quantification of species' habitat requirements and thus, could represent a valuable tool for pest management purposes. By providing examples of current issues of grapevine pests in viticulture, we discuss the use of SDMs in agricultural risk analysis and highlight their advantages and caveats.

The authors systematically reviewed all of the etiopathologic factors discussed in the literature to verify the classification of de Quervain tenosynovitis on the list of occupational diseases. The authors searched Ovid MEDLINE, EMBASE, and the Cochrane Library for articles discussing the cause of de Quervain tenosynovitis. The literature was classified by the level of evidence presented, the etiopathologic hypothesis discussed, the authors' conclusion about the role of the etiopathologic hypothesis, and the first author's professional background. The quality of reporting of the observational studies was evaluated by an extended Strengthening the Reporting of Observational Studies in Epidemiology statement checklist. A meta-analysis of all controlled cohort studies was performed. The Bradford Hill criteria were used to evaluate a causal relationship between de Quervain tenosynovitis and occupational risk factors. A total of 179 references were found, and 80 articles were included. On average, only 35 percent (median, 35 percent; range, 16 to 60 percent) of all items on the extended Strengthening the Reporting of Observational Studies in Epidemiology checklist were addressed per article. The meta-analysis to evaluate the strength of the association between de Quervain tenosynovitis and (1) repetitive, (2) forceful, or (3) ergonomically stressful manual work suggested an odds ratio of 2.89 (95 percent CI, 1.4 to 5.97; p = 0.004). No evidence was found to support the Bradford Hill criteria for a causal relationship between de Quervain tenosynovitis and occupational risk factors. No sufficient scientific evidence was provided to confirm a causal relationship between de Quervain tenosynovitis and occupational risk factors. Risk, III.

Full Text Available Background: Cardiovascular disease (CVD is the main mortality cause worldwide. Noise and vibration are considered to be occupational risk factors, but little is known about their cardiovascular effects in Bulgaria in terms of gender and various professional groups. The aim of this study has been to investigate the risk of prevalent CVD, associated with occupational noise and vibration exposure. Material and Methods: We conducted a secondary analysis of the data from 3 waves of the European Working Conditions Survey (EWCS 2001–2010 – a nationally-representative cross-sectional questionnaire survey covering 3149 workers aged ≥ 15 years in Bulgaria. Data on self-reported heart disease were linked to self-reported occupational noise and vibration, adjusting for other factors. Results from the 3 waves were pooled together using the inverse variance heterogeneity (IVhet meta-analysis. Results: For noise, the risk was elevated among women (relative risk (RR = 1.26, 95% confidence interval (CI: 0.53–3.01, but not men (RR = 0.49, 95% CI: 0.14–1.65. Long-term workers had RR = 1.01, 95% CI: 0.60–1.69. For vibration, the risk was increased in all participants. It was higher among men (RR = 2.56, 95% CI: 1.60–4.09 than it was among women (RR = 1.32, 95% CI: 0.77–2.27. Among long-term, industrial, and service workers it was RR = 1.56, 95% CI: 1.02–2.40; RR = 1.10, 95% CI: 0.61–1.98, and RR = 1.18, 95% CI: 0.57–2.46, respectively. Conclusions: Occupational vibration was a risk factor for prevalent heart disease in Bulgaria. Noise was an alleged risk factor only among long-term workers and women. Med Pr 2016;67(4:435–445

X-rays in medical diagnostic are the major source of Bulgarian population exposure to ionizing radiations. Diagnostic X-ray is the most diagnostic application and is used in a wide variety of examinations. The modern concept for radiation protection of patients in diagnostic radiology is based on two main principles: justification of the examinations and radiation protection optimization. It is pointed out that the collective effective dose of radiation may be considerably reduced by decreasing the number of clinically unwarranted X-ray examination of storage and delivery of diagnostic information and adopting a system for physical and technical quality control of the X-ray equipment. The aim of this investigation is assessment of the collective effective doses for the patients with occupational diseases exposed to ionizing radiation by radiological diagnostics. The study covers the period of 1990 through 1999. A total of 3293 patients, treated in the Department of Occupational Toxicology, Clinic of Occupational Diseases, Medical University - Sofia, were examined with X-ray and KT (cervical and lumbar spine, chest, skull, stomach, extremities, pelvis, brain). Most of the observed patients were with predominantlyheavy metals poisonings and a few with other chemical agents poisonings. Number of patients with radiological examinations was 1938, number of examination per capita was 0,59 and the total number of radiological examinations was 2536. The average number of radiological examination for one patient was 1,36, the most number of radiological examinations for one patient was 4. The collective effective dose for an examined patient was 1803 man.mSv. Our results shown the essential of the raising ensure that the medical exposure of patients be the minimum necessary to achieve the required diagnostic objective. (author)
Full Text Available Abstract Background The to date evidence for a dose-response relationship between physical workload and the development of lumbar disc diseases is limited. We therefore investigated the possible etiologic relevance of cumulative occupational lumbar load to lumbar disc diseases in a multi-center case-control study. Methods In four study regions in Germany (Frankfurt/Main, Freiburg, Halle/Saale, Regensburg, patients seeking medical care for pain associated with clinically and radiologically verified lumbar disc herniation (286 males, 278 females or symptomatic lumbar disc narrowing (145 males, 206 females were prospectively recruited. Population control subjects (453 males and 448 females were drawn from the regional population registers. Cases and control subjects were between 25 and 70 years of age. In a structured personal interview, a complete occupational history was elicited to identify subjects with certain minimum workloads. On the basis of job task-specific supplementary surveys performed by technical experts, the situational lumbar load represented by the compressive force at the lumbosacral disc was determined via biomechanical model calculations for any working situation with object handling and load-intensive postures during the total working life. For this analysis, all manual handling of objects of about 5 kilograms or more and postures with trunk inclination of 20 degrees or more are included in the calculation of cumulative lumbar load. Confounder selection was based on biologic plausibility and on the change-in-estimate criterion. Odds ratios (OR and 95% confidence intervals (CI were calculated separately for men and women using unconditional logistic regression analysis, adjusted for age, region, and unemployment as major life event (in males or psychosocial strain at work (in females, respectively. To further elucidate the contribution of past physical workload to the development of lumbar disc diseases, we performed lag

Heavy metals and metalloids contamination in soils, water, food and livers of wild rats have been studied in Kumasi, Ghana and despite the estimated risks to residents, there is no epidemiological study to ascertain these projections. In addition, the World Health Organization and International Agency for Research on Cancer have reported an increase in respiratory diseases and cancers, in Ghana. The study's purpose was therefore to explore the potential associations between metal exposure and occurrences of respiratory diseases, lipid peroxidation and/or DNA damage to different age groups and sexes in Kumasi. Human urine was collected from the general population in urban and control sites in Kumasi and nine metals were measured in each sample. Results showed that although Zn was the most abundant total urinary As concentration was higher in 83% of samples compared to reference values. Urinary concentrations of metals, malondialdehyde (MDA) and 8-hydroxy-2-deoxy-guanosine (8-OHdG) were higher in urban sites compared to the control site. Based on the results obtained, there was no significant correlation between urinary metals and age. However, urinary Cd and MDA were highest in age groups 61-85 and 3-20 years, respectively. Significantly higher levels of urinary Co, As and Cd were detected in female participants. The study revealed that exposure to As was significantly associated with increased odds of asthma (odds ratio (OR) = 2.76; CI: 1.11-6.83) and tachycardia (OR = 3.93; CI: 1.01-15.4). Significant association was observed between urinary metals and MDA and 8-OHdG indicating possibility of lipid peroxidation and/or DNA damage in Kumasi residents. Copyright © 2017 Elsevier Ltd.

The aim of the study was to prove in a region in the North-West of Germany that there is the possibility to decrease the prevalence of latent Aujeszky's Disease infections by means of a systematic vaccination. For this, the most important precondition of the success in a high population immunity that is maintained also in the finishing pig until slaughter. Since it is known that maternal antibodies interfere with the active immunization in the prefattening period, procedures were to be found that guarantee a high immunity in spite of the colostral antibodies. The results of the study show that the existing recommendation for vaccinating fattening pigs are sufficient for the prevalence of latent infections. They also confirm the necessity to carry out a check- and slaughter policy at the end of the eradication program.

We considered the totality of patients diagnosed with basal cell carcinoma and squamous cell histological study of skin biopsy or surgical excision. Risk factors with possible association with the disease were studied, such as sun exposure, ionizing and non-ionizing radiations and a wide range of chemical and biological substances potentially carcinogenic
Full Text Available Background: Development of periodontal disease (PD may be affected by socioeconomic status. This study examined the relationship between occupational status and PD in a 5-year prospective cohort of Japanese workers. Methods: In total, 19,633 participants had initial examinations at the Aichi Health Promotion Foundation, of whom 8210 participants aged 20 years or older did not have PD. Follow-up examinations were conducted for 3757 participants, accounting for 45.8% of baseline participants. Ultimately, 3390 participants were analyzed according to the criterion of job classification at baseline, which was based on the International Standard Classification of Occupations, 1987. Oral examinations were performed using the Community Periodontal Index (CPI. The CPI scores were coded as follows: healthy (score of 0; bleeding after probing (1; dental calculus (2; shallow pockets (3; and deep pockets (4. Participants with one or more sextants with a score >2 were diagnosed with PD. Poisson regression analysis was performed to adjust for age and other potential confounders. Results: Overall, 31.6% of men and 23.8% of women had developed PD (CPI scores of 3 or 4. The adjusted relative risk (RR for PD (CPI scores of 3 or 4 in men was not significant. On the other hand, the adjusted RRs for PD (CPI score of 4 in men were 2.52-, 2.39-, and 2.74-fold higher for skilled workers, sales persons, and drivers, respectively, than for professionals. In contrast, we found no gradient in women. Conclusions: We found a gradient related to the risk of developing PD according to occupational status among men in a Japanese worker population.

Coeliac disease (CD) is the most common Th1-mediated enteropathy, frequently associated with other immune-mediated disorders (IMD). To evaluate: (1) the prevalence of IMD at the time of and after CD diagnosis; (2) a possible change in immune response to gluten free diet (GFD); (3) the potential role of GFD in reducing and/or preventing IMD in CD. Prospective study including all consecutive adult CD patients who underwent investigations for Th1-Th17/Th2-IMD at the time of CD diagnosis and after a 5-year follow-up period. 1255 CD were enrolled. Of these, 257 patients (20.5%) showed IMD at the time of CD diagnosis, with 58.4% presenting a Th1/Th17-IMD. After a 5-year follow-up period, 682 patients (54.3%) showed new IMD despite GFD. Of these, 57.3% presented a Th1/Th17-IMD and 42.7% a Th2-IMD (p=0.8). When compared the prevalence of each type of IMD before and after CD diagnosis, we did not identify any significant "switch" from Th1/Th17- to Th2-IMD or vice versa. The number of patients with Th1/Th17- and/or Th2-IMD increased during the GFD period (20.5% vs 54.3%; p<0.01; OR 1.9). The prevalence of IMD at the time of CD diagnosis is high and it seems to increase in the follow-up period despite GFD. Copyright © 2016 Editrice Gastroenterologica Italiana S.r.l.

Context In the South African mining sector, cardiorespiratory-specific autopsies are conducted under the Occupational Diseases in Mines and Works Act (ODMWA) on deceased mineworkers to determine eligibility for compensation. However, low levels of autopsy utilisation undermine the value of the service. Objective To explore enablers and barriers to consent that impact on ODMWA autopsy utilisation for posthumous monetary compensation. Methods In-depth interviews were conducted with mineworkers, widows and relatives of deceased mineworkers as well as traditional healers and mine occupational health practitioners. Results A range of socio-cultural barriers to consent for an autopsy was identified. These barriers were largely related to gendered power relations, traditional and religious beliefs, and communication and trust. Understanding these barriers presents opportunities to intervene so as to increase autopsy utilisation. Conclusions Effective interventions could include engagement with healthy mine-workers and their families and re-evaluating the permanent removal of organs. The study adds to our understanding of utilisation of the autopsy services. PMID:23364088

The International Classification of High-Resolution Computed Tomography (HRCT) for Occupational and Environmental Respiratory Diseases (ICOERD) is used to screen and diagnose respiratory illnesses. Using univariate and multivariate analysis, we investigated the relationship between subject characteristics and parenchymal abnormalities according to ICOERD, and the results of ventilatory function tests (VFT). Thirty-five patients with and 27 controls without mineral-dust exposure underwent VFT and HRCT. We recorded all subjects' occupational history for mineral dust exposure and smoking history. Experts independently assessed HRCT using the ICOERD parenchymal abnormalities (Items) grades for well-defined rounded opacities (RO), linear and/or irregular opacities (IR), and emphysema (EM). High-resolution computed tomography showed that 11 patients had RO; 15 patients, IR; and 19 patients, EM. According to the multiple regression model, age and height had significant associations with many indices ventilatory functions such as vital capacity, forced vital capacity, and forced expiratory volume in 1 s (FEV1). The EM summed grades on the upper, middle, and lower zones of the right and left lungs also had significant associations with FEV1 and the maximum mid-expiratory flow rate. The results suggest the ICOERD notation is adequate based on the good and significant multiple regression modeling of ventilatory function with the EM summed grades.

The National Cardiovascular Disease (NCVD) Database Registry represents one of the first prospective, multi-center registries to treat and prevent coronary artery disease (CAD) in Malaysia. Since ethnicity is an important consideration in the occurrence of acute coronary syndrome (ACS) globally, therefore, we aimed to identify the role of ethnicity in the occurrence of ACS among high-risk groups in the Malaysian population. The NCVD involves more than 15 Ministry of Health (MOH) hospitals nationwide, universities and the National Heart Institute and enrolls patients presenting with ACS [ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA)]. We analyzed ethnic differences across socio-demographic characteristics, hospital medications and invasive therapeutic procedures, treatment of STEMI and in-hospital clinical outcomes. We enrolled 13,591 patients. The distribution of the NCVD population was as follows: 49.0% Malays, 22.5% Chinese, 23.1% Indians and 5.3% Others (representing other indigenous groups and non-Malaysian nationals). The mean age (SD) of ACS patients at presentation was 59.1 (12.0) years. More than 70% were males. A higher proportion of patients within each ethnic group had more than two coronary risk factors. Malays had higher body mass index (BMI). Chinese had highest rate of hypertension and hyperlipidemia. Indians had higher rate of diabetes mellitus (DM) and family history of premature CAD. Overall, more patients had STEMI than NSTEMI or UA among all ethnic groups. The use of aspirin was more than 94% among all ethnic groups. Utilization rates for elective and emergency percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) were low among all ethnic groups. In STEMI, fibrinolysis (streptokinase) appeared to be the dominant treatment options (>70%) for all ethnic groups. In-hospital mortality rates for STEMI across ethnicity ranges from 8.1% to 10.1% (p = 0
Full Text Available Medical services, physicians and nurses play an essential role in the plant safety program through primary treatment of injured workers and by helping to identify workplace hazards. The physician and nurse should participate in the worksite investigations to identify specific hazard or stresses potentially causing the occupational accidents and injuries and in planning the subsequent hazard control program. Physicians and nurses must work closely and cooperatively with supervisors to ensure the prompt reporting and treatment of all work related health and safety problems. Occupational accidents, work related injuries and fatalities result from multiple causes, affect different segments of the working population, and occur in a myriad of occupations and industrial settings. Multiple factors and risks contribute to traumatic injuries, such as hazardous exposures, workplace and process design, work organization and environment, economics, and other social factors. With such a diversity of theories, it will not be difficult to understand that there does not exist one single theory that is considered right or correct and is universally accepted. These theories are nonetheless necessary, but not sufficient, for developing a frame of reference for understanding accident occurrences. Prevention strategies are also varied, and multiple strategies may be applicable to many settings, including engineering controls, protective equipment and technologies, management commitment to and investment in safety, regulatory controls, and education and training. Research needs are thus broad, and the development and application of interventions involve many disciplines and organizations.

The authors give some data on restitutional therapy of 516 patients (400 with sequelae following strokes and 116 with transient disorders of cerebral circulation). Treatment of the first group was made in a neurological ward, the second--in a cardiological sanatorium. The programme of restitutional therapy provided the use of psychosocial and biological methods, an appeal to the personality and stage-by-stage accomplishment of rehabilitative measures. Comprehensive restitutional therapy included psychotherapy, medical-activizing regimes, medical gymnastics, massage, occupational therapy, medicinal therapy, etc. The authors elaborated differentiated complexes of rehabilitative treatment for patients with spastic hemiparesis, normal or decreased tone, as well as for patients with transient disorders of cerebral circulation in conditions of a cardiological sanatorium. The indices of effectiveness were the following: an improvement of the condition in patients after brain strokes--97.8%, in patients with transient disorders of cerebral circulation--94%.

Patients with CKD and ESRD present with many health problems, which may lead to increased mortality and dysfunction. Numerous comorbidities may contribute toward physical, emotional, and social problems and a decreased quality of life. Difficulty ambulating, balance deficits, joint pain and stiffness, muscle spasm and weakness, fatigue, neuropathy, and difficulty with activities of daily living (ADLs) may contribute to a decrease in functional independence. Physical therapy (PT) and occupational therapy (OT) aim to restore physical functioning, facilitate independence in ADLs, and promote functional independence by using various therapeutic procedures. PT and OT are the usual services of choice to address impaired function associated with acute and chronic pathology. The purpose of this article is multifold: (1) to describe specific interventions provided by PTs and OTs that may be beneficial to individuals with CKD and ESRD, (2) to identify and describe the potential benefits of rehabilitation for these patient populations, and (3) to provide programmatic rehabilitation recommendations for patients with CKD and ESRD.

The Occupational Disease Prevention and Control Act (ODPC-Act) of the People's Republic of China came into effect on May 1, 2002. Given the scope of foreign-invested enterprises (FIEs) in China and an unabated increasing trend of foreign investment, compliance with the ODPC-Act among FIEs is of particular interest, yet little is known. The extent to which an employer educates its workforce to understand the ODPC-Act may be a measure of an employer's compliance. Based on a 25-item questionnaire survey, we found that among 166 workers from three FIEs in Wuxi, Jiangsu Province, the majority had little knowledge regarding the ODPC-Act; many were unaware of their rights granted under the ODPC-Act. They were also unable to recognize employers' potential violations of the ODPC-Act. Improving FIE workers' awareness of the ODPC-Act is desirable.

Full Text Available Biodiversity losses are occurring worldwide due to a combination of stressors. For example, by one estimate, 40% of amphibian species are vulnerable to extinction, and disease is one threat to amphibian populations. The emerging infectious disease chytridiomycosis, caused by the aquatic fungus Batrachochytrium dendrobatidis (Bd, is a contributor to amphibian declines worldwide. Bd research has focused on the dynamics of the pathogen in its amphibian hosts, with little emphasis on investigating the dynamics of free-living Bd. Therefore, we investigated patterns of Bd occupancy and density in amphibian habitats using occupancy models, powerful tools for estimating site occupancy and detection probability. Occupancy models have been used to investigate diseases where the focus was on pathogen occurrence in the host. We applied occupancy models to investigate free-living Bd in North American surface waters to determine Bd seasonality, relationships between Bd site occupancy and habitat attributes, and probability of detection from water samples as a function of the number of samples, sample volume, and water quality. We also report on the temporal patterns of Bd density from a 4-year case study of a Bd-positive wetland. We provide evidence that Bd occurs in the environment year-round. Bd exhibited temporal and spatial heterogeneity in density, but did not exhibit seasonality in occupancy. Bd was detected in all months, typically at less than 100 zoospores L(-1. The highest density observed was ∼3 million zoospores L(-1. We detected Bd in 47% of sites sampled, but estimated that Bd occupied 61% of sites, highlighting the importance of accounting for imperfect detection. When Bd was present, there was a 95% chance of detecting it with four samples of 600 ml of water or five samples of 60 mL. Our findings provide important baseline information to advance the study of Bd disease ecology, and advance our understanding of amphibian exposure to free

Global and regional species conservation efforts are hindered by poor distribution data and range maps. Many Indian primates face extinction, but assessments of population status are hindered by lack of reliable distribution data. We estimated the current occurrence and distribution of 15 Indian primates by applying occupancy models to field data from a country-wide survey of local experts. We modeled species occurrence in relation to ecological and social covariates (protected areas, landscape characteristics, and human influences), which we believe are critical to determining species occurrence in India. We found evidence that protected areas positively influence occurrence of seven species and for some species are their only refuge. We found evergreen forests to be more critical for some primates along with temperate and deciduous forests. Elevation negatively influenced occurrence of three species. Lower human population density was positively associated with occurrence of five species, and higher cultural tolerance was positively associated with occurrence of three species. We find that 11 primates occupy less than 15% of the total land area of India. Vulnerable primates with restricted ranges are Golden langur, Arunachal macaque, Pig-tailed macaque, stump-tailed macaque, Phayre's leaf monkey, Nilgiri langur and Lion-tailed macaque. Only Hanuman langur and rhesus macaque are widely distributed. We find occupancy modeling to be useful in determining species ranges, and in agreement with current species ranking and IUCN status. In landscapes where monitoring efforts require optimizing cost, effort and time, we used ecological and social covariates to reliably estimate species occurrence and focus species conservation efforts. ??

Full Text Available Occupational dermatoses contribute to a significant portion of work-related diseases, especially in Asia, where a major portion of the workforce is in the unorganized sector. This review article is focussed on the frequency and pattern of occupational skin diseases reported across Asian countries and type of allergens implicated in different occupations. The literature was searched systematically using key words 'occupational dermatoses,' 'occupational skin disease' and name of each Asian country. Ninty five full-text articles were considered relevant and evaluated. Some of the dermatoses seen in industrial workers in Asian countries are similar to those in Western countries, including dermatoses due to chromate in construction and electroplating workers, epoxy resin, and chromate in painters, wood dust in workers in the furniture industry, azo dyes in textile workers and formaldehyde and chromates in those working in the leather and dyeing industries, dermatoses in domestic workers, chefs and health-care workers. Dermatoses in workers engaged in agriculture, beedi (tiny cigars manufacture, agarbatti (incense sticks production, fish processing, carpet weaving, sanitation and those working in coffee plantations and coal mines appear to be unique to Asian countries. Recognition of clinical patterns and geographic variations in occupational skin diseases will provide an impetus to further strengthen future research in these areas, as well as improving their management.

The World Health Organization estimates that worldwide about 50 million new cases of occupational respiratory diseases emerge every year. Without preventative action, the burden of occupational diseases is expected to increase. In this thesis an alternative approach to deliver occupational health care is explored concerning work-related respiratory disorders in various worker populations. This approach is illustrated by a series of structured case studies. As a result of those studies it was ...

The strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting. The aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for increased asthma severity. We retrospectively reviewed the clinical charts of 72 patients who received a diagnosis of allergic occupational asthma, with or without associated occupational rhinitis. Our findings suggested that persistent asthma tended to be more common in subjects with associated occupational asthma and rhinitis, and occupational asthma severity was associated with occupational rhinitis severity. Moderate-severe persistent occupational rhinitis is a risk factor for persistent occupational asthma. We demonstrated, for the first time in the occupational setting, a significant association between occupational rhinitis and asthma severity.

Full Text Available In recent years occupational skin and respiratory diseases have been more and more frequently diagnosed in small production and service enterprises. The awareness of occupational exposure and its possible health effects among their workers and employers is not sufficient. Beauty salons, in addition to hairdressers and beauticians, frequently employ manicurists and pedicurists. The workers often happen to perform various activities interchangeably. The health status of beauty salons workers has rarely been assessed. The most numerous reports concern hairdressers. In this occupational group, the occurrence of skin lesions induced by wet work and frequent allergy to metals, hair dyes and bleaches and perm solutions has been emphasized, while information about health hazards for being a manicurist or pedicurist in beauty salons is seldom reported. The aim of this paper is to present professional activities (manicure and pedicure, methods of nail stylization, occupational exposure and literature data on work-related adverse health effects in manicurists and pedicurists. Wet work and exposure to solvents, fragrances, resins, metals, gum, detergents may cause skin disorders (contact dermatitis, urticaria, angioedema, photodermatoses, conjunctivitis, anaphylaxis, respiratory tract diseases, including asthma. The discussed occupations are also associated with the increased incidence of bacterial (particularly purulent, viral and fungal infections and cancer. Med Pr 2013;64(4:579–591

Individual-level concomitance of infectious diseases and noncommunicable diseases (NCDs) is poorly studied, despite the reality of this dual disease burden for many low- and middle-income countries (LMICs). This study protocol describes the implementation of a cohort and biobank aiming for a better understanding of interrelation of helminth and Plasmodium infections with NCD phenotypes like metabolic syndrome, hypertension, and diabetes. A baseline cross-sectional population-based survey was conducted over one year, in the Taabo health and demographic surveillance system (HDSS) in south-central Côte d'Ivoire. We randomly identified 1020 consenting participants aged ≥18 years in three communities (Taabo-Cité, Amani-Ménou, and Tokohiri) reflecting varying stages of epidemiological transition. Participants underwent health examinations consisting of NCD phenotyping (anthropometry, blood pressure, renal function, glycemia, and lipids) and infectious disease testing (infections with soil-transmitted helminths, schistosomes, and Plasmodium). Individuals identified to have elevated blood pressure, glucose, lipids, or with infections were referred to the central/national health center for diagnostic confirmation and treatment. Aliquots of urine, stool, and venous blood were stored in a biobank for future exposome/phenome research. In-person interviews on sociodemographic attributes, risk factors for infectious diseases and NCDs, medication, vaccinations, and health care were also conducted. Appropriate statistical techniques will be applied in exploring the concomitance of infectious diseases and NCDs and their determinants. Participants' consent for follow-up contact was obtained. Key results from this baseline study, which will be published in peer-reviewed literature, will provide information on the prevalence and co-occurrence of infectious diseases, NCDs, and their risk factors. The Taabo HDSS consists of rural and somewhat more urbanized areas, allowing for

As a legacy of the large asbestos consumption until the definitive ban in 1992, Italy is currently suffering a severe epidemic of asbestos related diseases. The aim of this paper is to describe the surveillance system for mesothelioma incidence and to provide evidences regarding the occurrence of the disease in Italy and the circumstances of asbestos exposure. Italian National Register of Malignant Mesotheliomas (ReNaM) is a permanent surveillance system of mesothelioma incidence, with Regional Operating Centres (CORs) active in each Italian region, identifying incident malignant mesothelioma (MM) cases from health care structures. Occupational history, lifestyle habits and residential history are obtained using a standardised questionnaire, administered by a trained interviewer, to the subject or to the next of kin. Descriptive epidemiological figures, occupations involved in exposures and territorial maps of MM cases have been produced. At December 2016, ReNaM has collected 27,356 MM cases for the incidence period between 1993 and 2015. The modalities of exposure to asbestos have been investigated for 21,387 (78%) and an occupational exposure has been defined for around 70% of interviewed cases (14,818). Non-occupational exposure is still relevant with 4.9% and 4.4% of cases for which respectively a familial exposure (due to the cohabitation with an occupational exposed subject) and an environmental exposure (due to the residence near a contaminated site) has been detected. The epidemiological surveillance of MM incident cases, by the means of a national register for estimating the occurrence of the disease and identifying the circumstances of asbestos exposure, is a relevant tool for preventing asbestos exposure, for supporting the effectiveness of insurance system and for estimating reliable epidemiological figures.

Conventional cage systems will be replaced by housing systems that allow hens to move freely. These systems may improve hens' welfare, but they lead to some disadvantages: disease, bone fractures, cannibalism, piling and lower egg production. New selection criteria for existing commercial strains should be identified considering individual data about laying performance and the behavior of hens. Many recording systems have been developed to collect these data. However, the management of double nest occupations remains critical for the correct egg-to-hen assignment. To limit such events, most systems adopt specific trap devices and additional mechanical components. Others, instead, only prevent these occurrences by narrowing the nest, without any detection and management. The aim of this study was to develop and test a nest usage "sensor", based on imaging analysis, that is able to automatically detect a double nest occupation. Results showed that the developed sensor correctly identified the double nest occupation occurrences. Therefore, the imaging analysis resulted in being a useful solution that could simplify the nest construction for this type of recording system, allowing the collection of more precise and accurate data, since double nest occupations would be managed and the normal laying behavior of hens would not be discouraged by the presence of the trap devices.

High incidences of neurodegenerative diseases, mainly dementia, parkinsonism, and amyotrophic lateral sclerosis, occur on the island of Guam (Koerner, 1952; Kurland and Mulder, 1954). The occurrence and description of the diseases and a summary of the investigations can be found in Perl (1997). The diseases have been more prevalent along the southern coast, particularly the small villages of Umatac, Merizo, and Inarajan (Reed and Brody, 1975; Roman, 1996; and Perl, 1997) (fig. 1), and referred to as the southern villages in this report. Tertiary volcanic rocks underlie most of the southern part of the island, including these villages. The northern part of Guam, with lower incidences of the diseases, consists of carbonate rocks. Epidemiological studies beginning in the early 1950’s failed to show the cause to be genetic etiology (Plato and others, 1986; Zhang and others, 1990). In recent studies, the search for pathogenic mechanisms has shifted to environmental factors. Excesses or deficiencies of various elements from dietary sources including drinking water can have an effect on human health. These deficiencies or excesses can usually be attributed to the geochemical composition of the rocks and derived soils that underlie the area. An example is the high concentration of Se in soil associated with the occurrence of selenosis in adults (Mills, 1996). Yase (1972) suggested that the neurodegenerative diseases on Guam may be related to accumulation of trace elements such as manganese and aluminum, both of which may cause neurodegeneration. It has been suggested that a deficiency in calcium and magnesium in the soil and water along with readily available aluminum could be connected to the occurrence of the diseases (Gajdusek, 1982; Yanagihara and others, 1984; Garruto and others, 1989). Some of the studies investigated metal exposure, particularly aluminum and manganese, and deficiencies in calcium and magnesium (Garruto and others, 1984). Aluminum has been shown to

At the present study, it was evaluated the claw diseases occurrence in cows and heifers from two farms of Minas Gerais state after rainy and dry periods. Cows kept in stables during dry period showed claw diseases more frequently. Claw diseases observed in these animals were heel erosion (group 1, digital dermatitis, interdigital dermatitis, and interdigital hyperplasia (group 2. Grazing cows during all year presented a decrease on the occurrence of claw diseases in the dry period, which demonstrated a relationship among lesions from groups 1 and 3 (sole hemorrhage, white line disease and double sole and the rain rate. Hygienic conditions of installations and paddocks also contributed to the occurrence of claw diseases in the animals.As afecções podais dos bovinos apresentam diversos fatores que predispõem a sua ocorrência.

Silicosis is an untreatable but preventable occupational disease, caused by exposure to silica. It can progressively evolve to lung impairment, respiratory failure and death, even after exposure has ceased. However, little is known about occupational diseases-related interest at the level of scientific community, media coverage and web behavior. This article aims at filling in this gap of knowledge, taking the silicosis as a case study. We investigated silicosis-related web-activities using Google Trends (GT) for capturing the Internet behavior worldwide in the years 2004-2015. GT-generated data were, then, compared with the silicosis-related scientific production (i.e., PubMed and Google Scholar), the media coverage (i.e., Google news), the Wikipedia traffic (i.e, Wikitrends) and the usage of new media (i.e., YouTube and Twitter). A peak in silicosis-related web searches was noticed in 2010-2011: interestingly, both scientific articles production and media coverage markedly increased after these years in a statistically significant way. The public interest and the level of the public engagement were witnessed by an increase in likes, comments, hashtags, and re-tweets. However, it was found that only a small fraction of the posted/uploaded material contained accurate scientific information. GT could be useful to assess the reaction of the public and the level of public engagement both to novel risk-factors associated to occupational diseases, and possibly related changes in disease natural history, and to the effectiveness of preventive workplace practices and legislative measures adopted to improve occupational health. Further, occupational clinicians should become aware of the topics most frequently searched by patients and proactively address these concerns during the medical examination. Institutional bodies and organisms should be more present and active in digital tools and media to disseminate and communicate scientifically accurate information. This

The present study sought to examine the long-term effects of exposure to respirable quartz on pulmonary function with particular focus on chronic obstructive pulmonary disease (COPD). The study is based on the Wismut cohort of former uranium miners. Spirometric data were ascertained together with quantitative estimates of cumulative exposure to respirable quartz for each of 1421 study subjects born between 1954 and 1956. The case definition for COPD is based on the criteria of the Global Initiative for Chronic Obstructive Lung Disease. Linear mixed regression models were fitted to identify significant determinants of longitudinal changes in lung function parameters. An average of five spirometries were available for each miner. It was shown that cumulative exposure to 1 mg/m(3)-year respirable quartz leads, on average, to a relative reduction in forced expiratory volume in 1 s/ orced vital capacity (FEV(1)/FVC) of 2.75% (pquartz (OR 1.81 per 1 mg/m(3)-year). This paper adds further evidence on the long-term effects of exposure to respirable quartz, which include a decline in pulmonary function parameters and an increase in the incidence of COPD.

In this research, we used data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe, and a measurement approach known as stochastic frontier analysis, derived from the economic literature. SHARE includes a large population (n > 25,000 geographically distributed across Europe, and analyzes several dimensions simultaneously, including physical and mental health activity. The main advantages of stochastic frontier analysis are that it allows estimation of parametric function relating cognitive scores and driving factors at the boundary and disentangles frontier noise and distance to frontier components, as well as testing the effect of potential factors on these distances simultaneously.

Full Text Available Occupational skin cancer and precancerous lesions are skin disorders caused by exposure to chemical carcinogens such as polycyclic hydrocarbons and arsenic, or radiation, such as ultraviolet light and ionizing light in the workplace. Annual increase in skin cancer incidence is believed to be related to various factors such as frequent intense sunlight exposure (i.e. at work, recreational activities, and sun-tanning habit, ozone depletion, an increase in number of geriatric population, and an increase of public awareness in skin cancer. The most common occupational skin cancers are basal cell carcinoma, squamous cell carcinoma, and melanoma. Examples of occupational precancerous lesion of the skin are actinic keratosis and Bowen’s disease. Particular diagnostic criteria to diagnose occupational diseases has been developed. Early detection of occupational skin cancer and precancerous lesion is necessary. An effective prevention program consists of primary prevention such as prevention of hazardous material exposure, secondary prevention such as early detection of disease for early intervention, and tertiary prevention such as minimizing long-term impact of the disease.
Conclusion: Occupational hazards and injuries among PAN workers are a frequent occurrence. There is need for sustained public awareness campaigns among the workers and management on the importance of occupational safety to guide against injuries/ accidents at work sites and compliance to the use of protective ...

Some data on 239 patients with Hodkin disease in a long-term (5-12 yrs.) remission achieved with radiotherapy, have been analysed. The number of married persons and the number of children in a family were less, and the number of divorces equal to indices determined during mass screening of population. The rates of morbidity with a less of capacity to work were consistent with control values. Most of the patients (90.3%) after therapy resumed their work the nature of which was mainly the same (88.6%). In expert medical evaluation of the working capacity there are no reliable criteria. It should proceed from the completeness of remission and the nature of the pathological process

Occupational contact dermatitis, including occupational allergic contact dermatitis, is one of the most common occupational diseases. Making a timely and accurate diagnosis is important to improving the outcome. Taking a work history and patch testing are essential elements in the diagnostic process. Management, based on an accurate diagnosis, must include both medical treatment to address the disease and workplace modifications as appropriate to reduce exposure the causative agents.

Full Text Available This paper aims to report the effects of the interventions, using the resource of assistive technology, carried out with a child with degenerative disease of the central nervous system at his home. This is a study case, which was conducted in seven meetings, addressing the child and his caregivers during a process of evaluation, preparation of assistive devices, family orientation, and evaluation of the family environment repercussion. The results showed that the child presents significant motor, cognitive, and psychosocial impairments, resulting in difficulties in performing activities of daily living, communication, and play. Adjustments were proposed to facilitate the child’s involvement and alleviate family difficulties on equipment and environments, such as wheelchair, bedroom, bathroom, orthosis, toys and communication. Finally, it was possible to note that the assistive technology resources were used according to the child’s needs and his own reality, and that the domiciliary visits contributed positively to the family’s life because they facilitated the child’s care, despite the limitations faced.

Accurate workplace injury data are useful in the prioritization of prevention strategies. In the UK, physicians report workplace ill-health data within The Health and Occupation Research (THOR) network, including injury case reports. To compare workplace injury data reported by occupational physicians (OPs) and general practitioners (GPs) to THOR. Injury cases reported by OPs and GPs, reported to THOR between 2006 and 2012 were analysed. Demographics, industrial groups, nature of injury, kind of accident and site of injury were compared. Data on sickness absence for workplace injuries reported by GPs were investigated. In total, 2017 workplace injury cases were reported by OPs and GPs. Males were more likely to sustain a workplace accident than females. Sprains and strains were reported most often, with the upper limbs being affected most frequently. Slips, trips and falls were identified as important causal factors by both OPs and GPs. Psychological injuries also featured in THOR reporting, with a higher proportion reported by OPs (21%) than by GPs (3%). The proportion of people classified as 'unfit' by GPs reduced following the introduction of the 'fit' note. THOR reports returned by OPs and GPs provide a valuable source of information of workplace injury data, and complement other sources of information, such as the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations and the Labour Force Survey. © The Author 2015.

Taxi drivers are at increased risk of cardiovascular disease (CVD), something which persists after correcting for the overrepresentation of traditional risk factors for CVD in this cohort. The contribution of lifestyle risk factors to this residually elevated CVD risk remains under-evaluated. We aimed to determine the prevalence of lifestyle risk factors for CVD, self-reported medical risk factors for CVD, and future risk of type 2 diabetes amongst Irish taxi drivers. Male taxi drivers with no history of CVD and type 2 diabetes and working in Galway city in the west of Ireland were invited to participate. Physical activity levels, dietary patterns, anthropometry, smoking, hypertension, hypercholesterolaemia, and Finnish Diabetes Risk Score (FINDRISC) values were recorded in a cross-sectional manner. 41 taxi drivers (mean age 56.7 ± 9.8 years) participated. 37 % were insufficiently active based on self-report, although only 8 % objectively achieved 10, 000 steps per day. Mean modified Mediterranean diet score (mMDS) was 4.6 ± 2.2, and only 13 % of participants had a normal body mass index (BMI) or waist circumference (WC). Those who worked for taxi companies tended to have a higher BMI (p = .07) and WC (p = .04) by multivariable regression. 22 % were current smokers, although a quit rate of 72 % was observed amongst the 78 % of taxi drivers who had ever smoked. 25 % were at high or very high risk of future type 2 diabetes. Lifestyle risk factors for CVD and dysglycaemia are prevalent amongst Irish taxi drivers.

Text mining is a flexible technology that can be applied to numerous different tasks in biology and medicine. We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence. For this reason, we have developed the DISEASES resource, which integrates the results from text mining with manually curated disease-gene associations, cancer mutation data, and genome-wide association studies from existing databases...

An understanding of students' perceptions of occupational therapy on entry is required to recognise how professional socialisation occurs through curriculum. Findings pertain to a qualitative study investigating students' perceptions of occupational therapy upon entry to two occupational therapy programmes in Australia. Students commencing Bachelor of Occupational Therapy and Masters of Occupational Therapy Studies programmes participated in the study (n = 462). A purpose-designed questionnaire was distributed to students in the first lecture of each programme. Preliminary analysis comprised identification of keywords/phrases and coding categories were generated from patterns of keywords. Frequency counts and percentages of keywords/phrases within categories were completed. Students' responses were categorised as 'what' occupational therapists do; 'how' they do it; 'why' they do it; and 'who' they work with. In 'what' occupational therapists do students frequently described 'helping' people. Both undergraduate and graduate entry masters students used the term 'rehabilitation' to describe how occupational therapy is done, with graduate entry students occasionally responding with 'through occupation' and 'modifying the environment'. Students perceived the 'why' of occupational therapy as getting back to 'everyday activities', with some students emphasising returning to 'normal' activities or life. Regarding the 'who' category, students also thought occupational therapists worked with people with an 'injury' or 'disability'. Students entered their occupational therapy programmes with perceptions consistent with the general public's views of occupational therapy. However, graduate entry students exposed to a pre-reading package prior to entry had more advanced occupational therapy concepts than undergraduate students. © 2011 The Authors.

The chronic kidney disease of unknown etiology (CKDu) among paddy farmers in was first reported in 1994 and has now become most important public health issue in dry zone of Sri Lanka. The objective was to identify risk factors associated with the epidemic in an area with high prevalence. A case control study was carried out in Padavi-Sripura hospital in Trincomalee district. CKDu patients were defined using health ministry criteria. All confirmed cases (N = 125) fulfilling the entry criteria were recruited to the study. Control selection (N = 180) was done from people visiting the hospital for CKDu screening. Socio-demographic and data related to usage of applying pesticides and fertilizers were studied. Drinking water was also analyzed using ICP-MS and ELISA to determine the levels of metals and glyphosate. Majority of patients were farmers (N = 107, 85.6%) and were educated up to 'Ordinary Level' (N = 92, 73.6%). We specifically analyzed for the effect modification of, farming by sex, which showed a significantly higher risk for male farmers with OR 4.69 (95% CI 1.06-20.69) in comparison to their female counterparts. In the multivariable analysis the highest risk for CKDu was observed among participants who drank well water (OR 2.52, 95% CI 1.12-5.70) and had history of drinking water from an abandoned well (OR 5.43, 95% CI 2.88-10.26) and spray glyphosate (OR 5.12, 95% CI 2.33-11.26) as a pesticide. Water analysis showed significantly higher amount of hardness, electrical conductivity and glyphosate levels in abandoned wells. In addition Ca, Mg, Ba, Sr, Fe, Ti, V and Sr were high in abandoned wells. Surface water from reservoirs in the endemic area also showed contamination with glyphosate but at a much lower level. Glyphosate was not seen in water samples in the Colombo district. The current study strongly favors the hypothesis that CKDu epidemic among farmers in dry zone of Sri Lanka is associated with, history of drinking water from a well

To examine if angiotensin-converting enzyme (ACE) inhibitor use delays the occurrence of renal involvement and decreases the risk of disease activity in SLE patients. SLE patients (Hispanics, African Americans and Caucasians) from the lupus in minorities: nature vs nurture (LUMINA) cohort were studied. Renal involvement was defined as ACR criterion and/or biopsy-proven lupus nephritis. Time-to-renal involvement was examined by univariable and multivariable Cox proportional hazards regression analyses. Disease activity was examined with a case-crossover design and a conditional logistic regression model; in the case intervals, a decrease in the SLAM-R score >or=4 points occurred but not in the control intervals. Eighty of 378 patients (21%) were ACE inhibitor users; 298 (79%) were not. The probability of renal involvement free-survival at 10 yrs was 88.1% for users and 75.4% for non-users (P = 0.0099, log rank test). Users developed persistent proteinuria and/or biopsy-proven lupus nephritis (7.1%) less frequently than non-users (22.9%), P = 0.016. By multivariable Cox proportional hazards regression analyses, ACE inhibitors use [hazard ratio (HR) 0.27; 95% CI 0.09, 0.78] was associated with a longer time-to-renal involvement occurrence whereas African American ethnicity (HR 3.31; 95% CI 1.44, 7.61) was with a shorter time. ACE inhibitor use (54/288 case and 254/1148 control intervals) was also associated with a decreased risk of disease activity (HR 0.56; 95% CI 0.34, 0.94). ACE inhibitor use delays the development of renal involvement and associates with a decreased risk of disease activity in SLE; corroboration of these findings in other lupus cohorts is desirable before practice recommendations are formulated.

The current state of eye diseases and treatments in the elderly as well as the relationships between dementia and systemic diseases remain unclear. Therefore, this study evaluated the prevalence of eye diseases, visual impairment, cognitive impairment, and falls (which are an important health issue and are considered one of the Geriatric Giants) in super-elderly people in Japan. The subjects were 31 elderly people (62 eyes; mean age: 84.6 ± 8.8 years; age range 61-98 years) who were admitted to a geriatric health services facility. Eye treatment status, systemic diseases, dementia, and recent falls were investigated. Eye examinations including vision and intraocular pressure measurement, and slit-lamp biomicroscopy were conducted. Mean best corrected visual acuity (logMAR) was 0.51 ± 0.56, and mean intraocular pressure was 13.7 ± 3.5 mmHg. Approximately half of the subjects exhibited excavation of the optic nerve head including cataracts and glaucoma. Ten subjects had visual impairment (i.e., visual acuity of the eye with the better vision visually impaired and non-visually impaired groups were 10.2 ± 6 and 16 ± 8 points, respectively (p visual impairment experienced a fall in the past year compared to 48% of those without visual impairment, although the difference was not significant. Regarding systemic diseases, there were 6, 5, and 15 cases of diabetes, hyperlipidemia, and hypertension, respectively. There was no significant difference between these systemic diseases and visual function after adjusted for age and gender. The percentages of patients with age-related eye diseases and poor visual acuity in a geriatric health services facility were extremely high. Compared to those without visual impairment, those with visual impairment had lower dementia scores and a higher rate of falls.

Pesticides have been widely used to control pest and pest-related diseases in agriculture, fishery, forestry and the food industry. In this review, we identify a number of respiratory symptoms and diseases that have been associated with occupational pesticide exposures. Impaired lung function has also been observed among people occupationally exposed to pesticides. There was strong evidence for an association between occupational pesticide exposure and asthma, especially in agricultural occupations. In addition, we found suggestive evidence for a link between occupational pesticide exposure and chronic bronchitis or COPD. There was inconclusive evidence for the association between occupational pesticide exposure and lung cancer. Better control of pesticide uses and enforcement of safety behaviors, such as using personal protection equipment (PPE) in the workplace, are critical for reducing the risk of developing pesticide-related symptoms and diseases. Educational training programs focusing on basic safety precautions and proper uses of personal protection equipment (PPE) are possible interventions that could be used to control the respiratory diseases associated with pesticide exposure in occupational setting.

To investigate the current status of occupational health and related countermeasures in Guangzhou, China. Related data were collected from occupational poisoning accident investigation, diagnosis and identification of occupational diseases, and the occupational disease hazard reporting system, and the statistical data of occupational health in Guangzhou were analyzed retrospectively. The number of enterprises reporting for occupational disease hazards in Guangzhou was 20 890, and the total number of workers was 1 457 583. The number of workers exposed to occupational hazards was 284 233, and the cumulative number of workers with occupational diseases was 1 502. There were many risk factors for occupational diseases in enterprises, and there were a large number of workers with occupational diseases, as well as newly diagnosed cases. From 2001 to 2014, the total number of cases of occupational diseases was 958. The situation for the prevention and control of occupational diseases is grim in Guangzhou. Occupational health supervision and law enforcement should be enhanced, the three-level supervision system should be established and perfected, and the occupational health supervision system with a combination of "prevention, treatment, and protection" should be established and promoted, so as to gradually establish a technical service support system for occupational health.

Anaemia is an important complication of inflammatory bowel disease [IBD]. The aim of this study was to determine the prevalence of anaemia and the practice of anaemia screening during the first year following diagnosis, in a European prospective population-based inception cohort. Newly diagnosed IBD patients were included and followed prospectively for 1 year in 29 European and one Australian centre. Clinical data including demographics, medical therapy, surgery and blood samples were collected. Anaemia was defined according to the World Health Organization criteria. A total of 1871 patients (Crohn's disease [CD]: 686, 88%; ulcerative colitis [UC]: 1,021, 87%; IBD unclassified [IBDU] 164. 81%) were included in the study. The prevalence of anaemia was higher in CD than in UC patients and, overall, 49% of CD and 39% of UC patients experienced at least one instance of anaemia during the first 12 months after diagnosis. UC patients with more extensive disease and those from Eastern European countries, and CD patients with penetrating disease or colonic disease location, had higher risks of anaemia. CD and UC patients in need of none or only mild anti-inflammatory treatment had a lower risk of anaemia. In a significant proportion of patients, anaemia was not assessed until several months after diagnosis, and in almost half of all cases of anaemia a thorough work-up was not performed. Overall, 42% of patients had at least one instance of anaemia during the first year following diagnosis. Most patients were assessed for anaemia regularly; however, a full anaemia work-up was frequently neglected in this community setting.

Full Text Available Diabetes mellitus (DM is a chronic metabolic disorder in which blood glucose level raises that can result in severe complications. However, the incidence increased mostly by obesity, pregnancy, persistent corpus luteum, and diestrus phase in humans and animals. This review has focused on addressing the possible understanding and pathogenesis of spontaneous DM in canine, feline, and few wild animals. Furthermore, pancreatic associated disorders, diabetic ketoacidosis, hormonal and drug interaction with diabetes, and herbal remedies associated with DM are elucidated. Bibliographic search for the present review was done using PubMed, Scopus, and Google Scholar for articles on concurrent DM in small and wild animals. Persistent corpus luteal and pseudopregnancy in female dogs generate gestational DM (GDM. GDM can also be caused by extensive use of drugs/hormones such as glucocorticosteroids. Although many similarities are present between diabetic cats and diabetic humans which present islet amyloidosis, there was a progressive loss of β- and α-cells and the normal number of δ-cells. The most prominent similarity is the occurrence of islet amyloidosis in all cases of diabetic cat and over 90% of human non-insulin dependent DM Type-2. Acute pancreatic necrosis (APN occurs due to predisposing factors such as insulin antagonism, insulin resistance, alteration in glucose tolerance, obesity, hyperadrenocorticism, and persistent usage of glucocorticoids, as these play a vital role in the progression of APN. To manage such conditions, it is important to deal with the etiological agent, risk factors, diagnosis of diabetes, and hormonal and drug interaction along with its termination with suitable therapy (herbal protocols. It should be noted that the protocols used for the diagnosis and treatment of human DM are not appropriate for animals. Further investigations regarding diabetic conditions of pets and wild animals are required, which will benefit the

There are few data available on the real-life pharmacokinetic and pharmacodynamics features of vedolizumab, a monoclonal antibody against integrin α4β7. We performed a prospective study of patients with inflammatory bowel diseases (IBDs) treated with vedolizumab to determine serum drug concentrations, formation of antivedolizumab antibodies (AVAs), and integrin α4β7 saturation. We performed a prospective study of 106 patients with IBD (67 with Crohn's disease and 39 with ulcerative colitis) treated with vedolizumab from September 2014 through March 2017 at 2 tertiary medical centers in Israel. Clinical data and serum samples were collected before and during induction and maintenance therapy. Clinical remission was defined as Harvey-Bradshaw index scores below 5 or as Simple Clinical Colitis Activity Index scores of 3 or less. We measured serum levels of vedolizumab, AVAs, and markers of inflammation. Peripheral blood mononuclear cells were obtained from some patients at designated trough time points and CD3+ CD45RO+ T cells were isolated from 36 samples. Cells were incubated with fluorescent-conjugated vedolizumab and flow cytometry was used to quantify α4β7 integrin saturation. We also performed flow cytometry analyses of CD3+ CD45RO+ lamina propria T cells isolated from intestinal mucosa of patients without IBD (non-IBD controls, n = 6), patients with IBD not treated with vedolizumab (untreated IBD controls, n = 8), and patients with IBD treated with vedolizumab (n = 15). Clinical remission was achieved by 48 of 106 patients (45%) by week 6 and 50 of 106 patients (48%) by week 14 of treatment. The median level of vedolizumab at week 6 was higher in patients in clinical remission (40.2 μg/mL) than in patients with active disease (29.7 μg/mL; P = .05). The median serum level of vedolizumab was significantly higher in patients with a normal level of C-reactive protein (21.8 μg/mL vedolizumab) vs the level in those with a high level of C-reactive protein

Niki de Saint Phalle's lifelong dialogue between art and diseases: psychological trauma of sexual abuse, transient selective IgA deficiency, occupational exposure to toxic plastic material, chronic lung disease, rheumatoid arthritis.
The French artist Niki de Saint Phalle (1930-2002) is one of the most famous female painter and sculptor of the 20th century. Her eventful live was full of emotional and physical burdens such as abuse by the father as a adolescent, early separation from family, nervous collapse, turbulent relationship with the artist Jean Tinguely, and last not least serious diseases. The psychological trauma of sexual abuse together with a "nervous breakdown" years later was the start of a life as an artist and is also a key to her art of the early years. She was affected from rheumatoid arthritis (RA) and was treated over 20 years with prednisolone and antimalarials leading to a good functional outcome and limited erosions of the wrist joint. Additionally, she had lifelong pulmonary disorders finally leading to death, which she attributed to polyester, the material used for her sculptures. An analysis of medical documents collected by her and provided by treating physicians gives another surprising explanation: selective IgA deficiency with multiple recurrent respiratory infections, asthma, milk intolerance, autoimmune thyroiditis, and RA compatible with hypogammaglobulinemia. Very unique in case of Niki de Saint Phalle is that IgA deficiency was transient. Nevertheless, it may be possible that the occupational exposure with art materials (polystyrene, polyester) has contributed in part or temporarily to her health problems. Altogether, her enormous artistic productivity represents an outstanding example of creative coping with RA and other lifelong health problems. Copyright © 2013. Published by Elsevier SAS.

Belo Horizonte, the capital of the State of Minas Gerais and its neighbourhood are the second industrial center of Brazil, concentrating many industries in several areas mainly metal refining and transformation. There are no registers about the level of metal concentration in the environmental air in the industry, nor even of the level of workers' contamination. The overall objective of this Project is to make a survey of the exposures to metals related to occupational diseases in galvanizing industry, which is responsible for the majority of occurrences of occupational diseases. The survey will be accomplished using as bio-indicators hair, nails, blood, urine, and individual air filters. These matrixes will indicate the incorporation of metals and the exposure level. The analytical techniques that will be applied are the neutron activation joined to related non nuclear analytical techniques, such as atomic absorption. (author)

The measurement of intracellular concentrations of adenosine triphosphate (iATP) in phytohemagglutinin-stimulated CD4(+) T cells constitutes a surrogate marker for post-transplant cell-mediated immunity (CMI). This assay has shown suboptimal accuracy for predicting infection after kidney transplantation (KT). We hypothesize that its predictive capacity depends on the specific contribution of the CMI to host-pathogen interactions. We assessed iATP levels in 100 KT recipients at baseline and months 1, 3, and 6 (363 measurements). No association was found between iATP at month 1 and the risk for overall or bacterial infection, although such association was evident for cytomegalovirus (CMV) disease (multivariate-adjusted hazard ratio [per 50-unit increment]: 0.83; P-value = 0.048). There were no significant differences in mean iATP between stable patients (319.4 ng/ml) and those developing overall (304.1 ng/ml) or bacterial infection (346.9 ng/ml) over the 45 days following monitoring. However, iATP was significantly lower in patients who developed CMV disease (223.5 ng/ml; P-values <0.002). The optimal cutoff (265 ng/ml) for predicting CMV disease in patients not receiving antiviral prophylaxis yielded sensitivity, specificity, positive, and negative predictive values of 85.7%, 68.3%, 15.2%, and 98.6%, respectively. In conclusion, a non-pathogen-specific monitoring of CMI by means of iATP informs the risk of CMV disease in KT recipients. © 2016 Steunstichting ESOT.

Cochrane reviews of physiotherapy (PT) and occupational therapy (OT) for Parkinson's disease found insufficient evidence of effectiveness, but previous trials were methodologically flawed with small sample size and short-term follow-up. To evaluate the clinical effectiveness and cost-effectiveness of individualised PT and OT in Parkinson's disease. Large pragmatic randomised controlled trial. Thirty-eight neurology and geriatric medicine outpatient clinics in the UK. Seven hundred and sixty-two patients with mild to moderate Parkinson's disease reporting limitations in activities of daily living (ADL). Patients were randomised online to either both PT and OT NHS services (n = 381) or no therapy (n = 381). Therapy incorporated a patient-centred approach with individual assessment and goal setting. The primary outcome was instrumental ADL measured by the patient-completed Nottingham Extended Activities of Daily Living (NEADL) scale at 3 months after randomisation. Secondary outcomes were health-related quality of life [Parkinson's Disease Questionnaire-39 (PDQ-39); European Quality of Life-5 Dimensions (EQ-5D)], adverse events, resource use and carer quality of life (Short Form questionnaire-12 items). Outcomes were assessed before randomisation and at 3, 9 and 15 months after randomisation. Data from 92% of the participants in each group were available at the primary time point of 3 months, but there was no difference in NEADL total score [difference 0.5 points, 95% confidence interval (CI) -0.7 to 1.7; p = 0.4] or PDQ-39 summary index (0.007 points, 95% CI -1.5 to 1.5; p = 1.0) between groups. The EQ-5D quotient was of borderline significance in favour of therapy (-0.03, 95% CI -0.07 to -0.002; p = 0.04). Contact time with therapists was for a median of four visits of 58 minutes each over 8 weeks (mean dose 232 minutes). Repeated measures analysis including all time points showed no difference in NEADL total score, but PDQ-39 summary index
Full Text Available Acute infectious diseases are the main problem in undeveloped countries, but still an important sociomedical problem in the developed world, due to high morbidity and mortality rates, economical losses and the suffering they cause. The aim of this study was to determine specific risk factors connected with knowledge, attitudes and practice (KAP study of adult inhabitants of the Republic of Serbia, which contribute to the appearance of infectious diseases according to territory (Belgrade, Vojvodina and Central Serbia, gender and age. The research on health conditions, health needs and utilization of health care of the population of Serbia were realized by the Public Health Institute of Serbia ‘Dr Milan Jovanovic Batut’, all IPHs in Serbia, WHO and UNICEF. A cross-sectional study was conducted in 9921 persons (52% women and 48% men. Hygienic habits were on the higher level in the population of Belgrade and Vojvodina compared to the Central Serbia: washing hands before meal (88,5:90,6:87,5%, p < 0,00046, on entering home (83,1:68,6:67,5%, p < 0,50, before using the toilet (50,8:46,9:40,1%, p < 00000, after using the toilet (92,3:93,7:91,4%, p < 0,0031. Before meal, 11, 5% of adults wash hands almost never or sometimes; on coming home every third person does not wash hands, before using the toilet more than 50%, and after using the toilet almost 8%. In this way, some intestinal infectious diseases and sexually transmitted diseases such as gonorrhoea, syphilis, HPV can be disseminated. Women have better hygienic habits than men, and younger persons have better hygienic habits than older persons. Every fifth man and every fourth woman does not accept personal responsibility for health. Habits and behavior that decrease individual immunity presented in high percent of the population of Serbia are: inappropriate eating habits, tobacco smoking, alcohol consumption, stress (63,5% women and 53,3% men; only 7,9% women and 15,2% men use condom regularly
Conclusion: We estimated occupational IHD mortality of Korea with updated data and more relevant evidence. Despite the efforts to obtain reliable estimates, there were many assumptions and limitations that must be overcome. Future research based on more precise design and reliable evidence is required for more accurate estimates.

Full Text Available We examined data provided by a healthcare facility at a large industrial enterprise focusing on occupational morbidity dynamics over 2013-2016 and periodical medical examinations results obtained in 2015 and 2016. We created a specialized program and applied it to conduct sociological research on health of workers who has a periodical medical examination. We detected that most questioned workers (50.48 % whose occupations were associated with dangerous and hazardous occupa-tional factors were poorly aware of occupational diseases prevention and needed relevant knowledge. It is shown that over 2013–2016 occupational morbidity decreased from 9.38 cases per 10,000 workers to 3.55 cases. However, it remained higher that in Russian and Perm region on average. All occupational diseases were detected in workers older than 40 with their working record being longer than 15 years. A share of people able to work with certain limitations grew in 2016 in comparison with 2015 (from 7.35 to 9.31 %; a number of people who needed sanatorium-resort therapy also grew from 19.96 to 32.12 %; a number of people with general somatic diseases increased from 31.23 to 70.17 %; health index reduced from 38.77 to 29.82 %. Musculoskeletal system diseases, con-nective tissue diseases, circulatory system diseases, eye and its accessory apparatus diseases, respiratory organs diseases, and digestive organs diseases prevailed in general somatic morbidity structure. We registered a substantial growth in hearing organs diseases (mostly hearing loss, from 49.47 to 99.06 cases per 100 examined; skin and subcutaneous tissue diseases (from 7.73 to 36.3 cases per 100 examined; urinary system diseases (from 68.42 to 100.62 cases per 100 examined. We detected that most examined workers pursued unhealthy lifestyle. For example, 29.9 % often consumed strong spirits (equally men and women, and 72.8 % smoked. All the respondents tended to have low physical activity. We also revealed some

Full Text Available Flowery cushion gall of cacao is a disease complex with six types. Fusarium decemcellulare have been isolated from both flowery and green point galls and recognized as the etiological agent of the disease. In the present work we: i identified by ITS-rDNA sequencing and/or taxonomy the cultivable fungal species or Operative Taxonomic Units (OTUs associated with the five symptoms of cushion galls in cacao from Venezuela, and ii determined the gall inducing capacity on cacao peeled seeds after 45 days of inoculation with suspensions of mycelia/ spores from distinct isolate types. The whole isolate collection rendered an abundance of 113 isolates with a richness of 39 OTUs (27 and eight identified at the species or genera levels, respectively, and in unidentified fungi. The dominant recovered species (≈36% were F. decemcellulare and Lasiodiplodia theobromae. Some isolates of F. decemcellulare, L. theobromae, F. equiseti, Fusarium spp., F. solani, F. incarnatum, Rhizocthonia solani and Penicillium sp. were pathogenic. Some other isolates of the first six mentioned taxa behave as non-pathogenic. Furthermore, pathogenic and non-pathogenic isolates can also co-occur within a single plant and gall type. Moreover, 2-5 species within a single gall symptom in a single tree were identified (not necessarily at the same point in the tree, indicating a broad diversity of co-occurring taxa.

The aim of this article is to reduce the risk of occupational hazards and improve safety conditions by enhancing hazard knowledge and identification as well as improving safety behavior for freight port enterprises. In the article, occupational hazards to health and their prevention measures of freight port enterprises have been summarized through a lot of occupational health evaluation work, experience and understanding. Workers of freight port enterprises confront an equally wide variety of chemical, physical and psychological hazards in production technology, production environment and the course of labor. Such health hazards have been identified, the risks evaluated, the dangers to health notified and effective prevention measures which should be put in place to ensure the health of the port workers summarized. There is still a long way to go for the freight port enterprises to prevent and control the occupational hazards. Except for occupational hazards and their prevention measures, other factors that influence the health of port workers should also be paid attention to, such as age, work history, gender, contraindication and even the occurrence and development rules of occupational hazards in current production conditions.
In addition to dust, gas, noise and vibrations, workers of extreme North extraction industries at Yakutsk are subjected to severely cold air temperatures, frozen soil and diminished daylight. Over a 5 year period, 3,860 workers were investigated clinically. Occupational diseases, pneumoconiosis and chronic dust bronchitis caused by dust, and vibration disease caused by machinery and noise were found. Pneumoconiotic diseases tended to progress rapidly to more severe stages and were found combined with tuberculosis, endobronchitis and bronchiectasis. Frequency of nonspecific para-occupational lung diseases on a background of dust caused pneumoconiotic diseases is evidently due to unfavorable meteorological conditions and decreased resistance of the organism to bacterial flora. Vibration disease common to machine operators, welders, bulldozers and dump truck drivers also progresess rapidly in extreme climatic conditions. Para-occupational neurovasculitis, osteo-articular inflammation and osteochondrosis exacerbate occupational disease. Combination of occupational and para-occupational diseases can lead to early incapacity of workers or to significant lost work periods. Therefore, early diagnosis of deviations of lungs, heart and neurovascular from normal even before symptoms are present clinically is imperative in order to treat symptoms while still reversible and preserve a core of workers in the extreme North.

Full Text Available Emerging infectious disease is a growing threat to global health, and recent discoveries reveal that the microbiota dwelling on and within hosts can play an important role in health and disease. To understand the capacity of skin bacteria to protect amphibian hosts from the fungal disease chytridiomycosis caused by Batrachochytrium dendrobatidis (Bd, we isolated 192 bacterial morphotypes from the skin of 28 host species of frogs (families Bufonidae, Centrolenidae, Hemiphractidae, Hylidae, Leptodactylidae, Strabomantidae, and Telmatobiidae collected from the eastern slopes of the Peruvian Andes (540–3,865 m a.s.l. in the Kosñipata Valley near Manu National Park, a site where we previously documented the collapse of montane frog communities following chytridiomycosis epizootics. We obtained isolates through agar culture from skin swabs of wild frogs, and identified bacterial isolates by comparing 16S rRNA sequences against the GenBank database using BLAST. We identified 178 bacterial strains of 38 genera, including 59 bacterial species not previously reported from any amphibian host. The most common bacterial isolates were species of Pseudomonas, Paenibacillus, Chryseobacterium, Comamonas, Sphingobacterium, and Stenotrophomonas. We assayed the anti-fungal abilities of 133 bacterial isolates from 26 frog species. To test whether cutaneous bacteria might inhibit growth of the fungal pathogen, we used a local Bd strain isolated from the mouthparts of stream-dwelling tadpoles (Hypsiboas gladiator, Hylidae. We quantified Bd-inhibition in vitro with co-culture assays. We found 20 bacterial isolates that inhibited Bd growth, including three isolates not previously known for such inhibitory abilities. Anti-Bd isolates occurred on aquatic and terrestrial breeding frogs across a wide range of elevations (560–3,695 m a.s.l.. The inhibitory ability of anti-Bd isolates varied considerably. The proportion of anti-Bd isolates was lowest at mid-elevations (6

Biodiversity losses are occurring worldwide due to a combination of stressors. For example, by one estimate, 40% of amphibian species are vulnerable to extinction, and disease is one threat to amphibian populations. The emerging infectious disease chytridiomycosis, caused by the aquatic fungus Batrachochytrium dendrobatidis (Bd), is a contributor to amphibian declines worldwide. Bd research has focused on the dynamics of the pathogen in its amphibian hosts, with little emphasis on investigating the dynamics of free-living Bd. Therefore, we investigated patterns of Bd occupancy and density in amphibian habitats using occupancy models, powerful tools for estimating site occupancy and detection probability. Occupancy models have been used to investigate diseases where the focus was on pathogen occurrence in the host. We applied occupancy models to investigate free-living Bd in North American surface waters to determine Bd seasonality, relationships between Bd site occupancy and habitat attributes, and probability of detection from water samples as a function of the number of samples, sample volume, and water quality. We also report on the temporal patterns of Bd density from a 4-year case study of a Bd-positive wetland. We provide evidence that Bd occurs in the environment year-round. Bd exhibited temporal and spatial heterogeneity in density, but did not exhibit seasonality in occupancy. Bd was detected in all months, typically at less than 100 zoospores L−1. The highest density observed was ∼3 million zoospores L−1. We detected Bd in 47% of sites sampled, but estimated that Bd occupied 61% of sites, highlighting the importance of accounting for imperfect detection. When Bd was present, there was a 95% chance of detecting it with four samples of 600 ml of water or five samples of 60 mL. Our findings provide important baseline information to advance the study of Bd disease ecology, and advance our understanding of amphibian exposure

This study investigated the incidence of mental harm due to occupational accidents and the relation between psychosocial factors at work and the occurrence of occupational accidents in the Netherlands for the construction industry and health and welfare sector. Analyses revealed that occupational accidents in the construction industry more often involved physical harm, whereas accidents in the health and welfare sector relatively more often resulted in mental harm, in comparison to other sectors. Results showed that psychosocial factors were associated with occupational accidents in both sectors. For the construction industry, high time pressure and exposure to violence and harassment by colleagues or supervisors were associated with occupational accidents. For the health and welfare sector, low autonomy and exposure to violence and harassment by colleagues or supervisors or by people outside the organization were associated with occupational accidents. The present paper stresses the importance of also taking psychological consequences and psychosocial factors at work into account in assessing the occurrence of occupational accidents.
There have been two High Court actions and seven inquests in the UK, with reference to the debate on occupational hazards of long term, low dose exposure. In July, 1987, two cases alleging that workers in the nuclear industry had contracted cancer due to their exposure to radiation at work had to be abandoned halfway through the trial after the judge had heard the medical evidence. A 57-year old man claimed that Hodgkin's disease had been caused by radiation while at work at Sellafield. However, medical opinion was that Hodgkin's disease had never been accepted as caused by radiation. In the second case a man who had died of stomach cancer at the age of 54 after working for UKAEA at Dounreay for 7 years, had received 190 mSv. The defendants' experts rated the likelihood of radiation as the cause at 3-6%; the plaintiffs' experts had suggested 30-50%. Seven inquest juries sitting in West Cumbria from 1983 to 1988 have brought in three verdicts of death caused by an industrial disease, three open verdicts, and one of natural causes. The men had all worked for BNFL at Sellafield for many years. (author)
Unexplained occurrence of multiple de novo pseudoaneurysms in patients with chronic kidney disease undergoing angioembolization for bleeding following percutaneous renal intervention: Are we dealing with infection or vasculitis?
Full Text Available Background and Objectives: Patients with chronic kidney disease (CKD are more prone for bleeding following percutaneous renal intervention, as compared to those with normal renal function. Causes are multi-factorial. Finding multiple aneurysms away from the site of renal intervention following initial angioembolization for hemorrhage is very unusual in these patients. Materials and Methods: Clinical and radiological findings of all the patients who underwent renal angiography for post-intervention bleed for a period of 5 years were reviewed and analyzed. Results: A total of 29 patients required angiography for post-intervention hemorrhage. Six patients had recurrence of hemorrhage for which they underwent repeat angiography. Four of these patients had appearance of multiple new aneurysms away from the site of percutaneous nephrostomy (PCN/percutaneous nephrolithotomy (PNL puncture and the site of previous bleeding. All the patients had CKD (creatinine >2.5 mg/dl. They were on prolonged preoperative urinary diversion and had polymicrobial urinary infection. Three patients had candiduria. None of these patients had re-bleeding after repeat embolization and treatment with antibacterial and antifungal agents. Conclusions: Development of multiple aneurysms away from the sites of punctures in patients with CKD following percutaneous intervention is very unusual. Its causation including infection with bacteria and fungus, reaction of embolizing material, and angiopathy needs to be explored.
Full Text Available Studies that explicitly and specifically take into account the spatial dimension within the study of eco-epidemiological systems remain rare. Our approach of modelling the spatial and/or temporal properties of the entomological and/or epidemiological data before their mapping with possible explanatory variables, objectively underline the significant patterns at different scales. The domiciliary and peri-domiciliary presence and abundance of juvenile and adult vectors of the Chagas disease (Triatoma sordida and Panstrongylus geniculatus in Bahia state in northeast Brazil, has been modelled by automatically identifying significant multi-scale spatial patterns of the entomological data by the application and adaptation of the spatial modelling methodology proposed by Dray et al. (2006 and based on principal coordinate analysis of neighbour matrices. We found that entomological data can be modelled by a set of eigenvectors that present a significant Moran’s I index of spatial autocorrelation. The models for juvenile and adult vectors are defined by 28 and 32 eigenvectors that explain 82.3% and 79.9%, respectively, of the total data variances. The results support insect presence as the outcome both of a local scale “near-to-near” dispersal and an infestation from the wild, surrounding environment that produces a higher insect density at the village periphery.

Summary: The past decade has seen an explosion in the development and application of models aimed at estimating species occurrence and occupancy dynamics while accounting for possible non-detection or species misidentification. We discuss some recent occupancy estimation methods and the biological systems that motivated their development. Collectively, these models offer tremendous flexibility, but simultaneously place added demands on the investigator. Unlike many mark–recapture scenarios, investigators utilizing occupancy models have the ability, and responsibility, to define their sample units (i.e. sites), replicate sampling occasions, time period over which species occurrence is assumed to be static and even the criteria that constitute ‘detection’ of a target species. Subsequent biological inference and interpretation of model parameters depend on these definitions and the ability to meet model assumptions. We demonstrate the relevance of these definitions by highlighting applications from a single biological system (an amphibian–pathogen system) and discuss situations where the use of occupancy models has been criticized. Finally, we use these applications to suggest future research and model development.

Objective: To understand the status of occupational health surveillance to workers exposed to toxic environment in a city, so as to provide scientific basis for strategy of occupational diseases prevention. Methods: In January 2017, collecting the data of on-the-job poisonous and harmful workers occupational health surveillance in the city from January 1, 2010 to December 31, 2016 in China Information System for Disease Control and Prevention, the trend of occupational health monitoring in the city was analyzed, and the differences between diverseeconomic types, enterprise scale, industry nature and hazard factors were analyzed and compared. Results: The occupational health examination rate showed an overall upward trend in workers exposed to dust in the city from 2010-2016 ( t =3.607, P occupational contraindications was on the rise in workers exposed to chemical factors ( t =3.071, P occupational contraindications and suspected occupational diseaseswere significant in different economic types, enterprise scale, industry nature and hazard factors ( P occupational contraindications was the highest among the large enterprises (1.24%) , the manufacturing industry (0.84%) and the state-owned economy (1.49%). The detection rate of suspected occupational diseases (0.04%) and occupational contraindications (1.15%) were the highest in the physical factors. Conclusion: Occupational health monitoring in the city is not optimistic. It is necessary to focuson the occupational health care of manufacturing practitioners, raise the detection rate of suspected occupational diseases, and standard the occupational health check work to protect the occupational health.

To survey current, Danish industrial noise levels and the use of hearing protection devices (HPD) over a 10-year period and to characterise the association between occupational noise and hearing threshold shift in the same period. Furthermore, the risk of hearing loss among the baseline and the follow-up populations according to first year of occupational noise exposure is evaluated. In 2001-2003, we conducted a baseline survey of noise- and hearing-related disorders in 11 industries with suspected high noise levels. In 2009-2010, we were able to follow up on 271 out of the 554 baseline workers (49%). Mean noise levels per industry and self-reported HPD use are described at baseline and follow-up. The association between cumulative occupational noise exposure and hearing threshold shift over the 10-year period was assessed using linear regression, and the risk of hearing loss according to year of first occupational noise exposure was evaluated with logistic regression. Over the 10-year period, mean noise levels declined from 83.9 dB(A) to 82.8 dB(A), and for workers exposed >85 dB(A), the use of HPD increased from 70.1 to 76.1%. We found a weak, statistically insignificant, inverse association between higher ambient cumulative noise exposure and poorer hearing (-0.10 dB hearing threshold shift per dB-year (95% confidence interval (CI): -0.36; 0.16)). The risk of hearing loss seemed to increase with earlier first year of noise exposure, but odds ratios were only statistically significant among baseline participants with first exposure before the 1980s (odds ratio: 1.90, 95% CI: 1.11; 3.22). We observed declining industrial noise levels, increased use of HPD and no significant impact on hearing thresholds from current ambient industrial noise levels, which indicated a successful implementation of Danish hearing conservation programs.
Full Text Available Unintentional injuries cause much of the global mortality burden, with the workplace being a common accident setting. Even in high-income economies, occupational injury figures remain remarkably high. Because risk factors for occupational injuries are prone to confounding, the present research takes a comprehensive approach. To better understand the occurrence of occupational injuries, sociodemographic factors and work- and health-related factors are tested simultaneously. Thus, the present analysis aims to develop a comprehensive epidemiological model that facilitates the explanation of varying injury rates in the workplace. The representative phone survey German Health Update 2010 provides information on medically treated occupational injuries sustained in the year prior to the interview. Data were collected on sociodemographics, occupation, working conditions, health-related behaviors, and chronic diseases. For the economically active population (18-70 years, n = 14,041, the 12-month prevalence of occupational injuries was calculated with a 95% confidence interval (CI. Blockwise multiple logistic regression was applied to successively include different groups of variables. Overall, 2.8% (95% CI 2.4-3.2 of the gainfully employed population report at least one occupational injury (women: 0.9%; 95% CI 0.7-1.2; men: 4.3%; 95% CI 3.7-5.0. In the fully adjusted model, male gender (OR 3.16 and age 18-29 (OR 1.54, as well as agricultural (OR 5.40, technical (OR 3.41, skilled service (OR 4.24 or manual (OR 5.12, and unskilled service (OR 3.13 or manual (OR 4.97 occupations are associated with higher chances of occupational injuries. The same holds for frequent stressors such as heavy carrying (OR 1.78, working in awkward postures (OR 1.46, environmental stress (OR 1.48, and working under pressure (OR 1.41. Among health-related variables, physical inactivity (OR 1.47 and obesity (OR 1.73 present a significantly higher chance of occupational injuries

Serum samples were obtained from 602 calves (from 19 groups in four feedlots: three in Ontario, and one in Alberta) upon arrival at the feedlot and 28 d later. Of these calves, 202 developed bovine respiratory disease (BRD) and 400 did not develop BRD. Based on high antibody titers noted upon arrival, we infer that most calves were exposed to Haemophilus somnus prior to arrival at the feedlot. Within a group, calves with high titers on arrival had a reduced risk of developing BRD later. Most calves did not experience titer increases after arrival; however, calves that had stable or increasing titers had a relatively low risk of contracting BRD. The calves at greatest risk of BRD were those with titers on arrival of less than 6.8 units and subsequent titer decreases of more than 1 unit. The effects of both the titer on arrival and the titer change after arrival were stable when the serologic effects of a number of viruses and Mycoplasma agents were considered. Neither antibody titer on arrival nor titer change was related to weight gain differences among calves. Calves with BRD or calves with lower weight on arrival had decreased weight gains in the first 28-day feeding period. The high titers on arrival may have protected most calves against further infection with H. somnus. However, since the calves that developed BRD had large titer increases to a number of viruses and to Pasteurella haemolytica, while having decreased antibody titers to H. somnus, we infer that the existing antibodies were "used up" in combatting the agents, including H. somnus, which may have "caused" the BRD. Calves which were able to increase their antibody levels to H. somnus tended to have a reduced risk of BRD.

In this article, current status of noise exposure in workplaces, trend of workers with noise-induced hearing loss (NIHL), and prevalence of NIHL in workers by industry and job category in Korea were reviewed. In addition, trends of research on the audiological effects such as hearing loss from noise and occupational hearing loss from non-noise in Korea were addressed through reports in industrial audiology. Though noise exposure level has improved, noise still shows the highest rate of cases exceeding exposure limit among workplace hazards. NIHL is the most common occupational disease except work-related disease such as musculoskeletal disorders and cerebrovascular diseases, and NIHL prevalence is thought to be much higher than reported in official publications. Noise affecting hearing comes from various sources such as workplaces, military settings, areas with exposure to high noise, and specific noise sources. There is also occupational hearing loss by non-noise including chemicals such as organic solvents and heavy metals, barotrauma, and trauma due to welding spark. Noise affects daily life through audiological effects such as hearing loss and tinnitus, non-audiological physical effects (e.g., cardiovascular), and psychosocial and behavioral effects. Development of systematic and comprehensive hearing conservation programs for lowering the noise level in workplaces and preventing the NIHL, and preparation of technological, administrative system for its settlement at workplace are urgently needed.

Plague remains a public health concern worldwide, but particularly in Africa. Despite the long-standing history of human plague, it is difficult to get a historical and recent overview of the general situation. We searched and screened available information sources on human plague occurrences...... in African countries and compiled information on when, where and how many cases occurred in a centralised database. We found records that plague was probably already present before the third pandemic and that hundreds of thousands of human infections have been reported in 26 countries since 1877...... Africa and Madagascar. We show that public health concerns regarding the current plague situation are justified and that the disease should not be neglected, despite the sometimes questionability of the numbers of cases. We conclude that improving plague surveillance strategies is absolutely necessary...

The International Classification of High-resolution Computed Tomography (HRCT) for Occupational and Environmental Respiratory Diseases (ICOERD) has been developed for the screening, diagnosis, and epidemiological reporting of respiratory diseases caused by occupational hazards. This study aimed to establish a correlation between readings of HRCT (according to the ICOERD) and those of chest radiography (CXR) pneumoconiotic parenchymal opacities (according to the International Labor Organization Classification/International Classification of Radiographs of Pneumoconioses [ILO/ICRP]). Forty-six patients with and 28 controls without mineral dust exposure underwent posterior-anterior CXR and HRCT. We recorded all subjects' exposure and smoking history. Experts independently read CXRs (using ILO/ICRP). Experts independently assessed HRCT using the ICOERD parenchymal abnormalities grades for well-defined rounded opacities (RO), linear and/or irregular opacities (IR), and emphysema (EM). The correlation between the ICOERD summed grades and ILO/ICRP profusions was evaluated using Spearman's rank-order correlation. Twenty-three patients had small opacities on CXR. HRCT showed that 21 patients had RO; 20 patients, IR opacities; and 23 patients, EM. The correlation between ILO/ICRP profusions and the ICOERD grades was 0.844 for rounded opacities (p<0.01). ICOERD readings from HRCT scans correlated well with previously validated ILO/ICRP criteria. The ICOERD adequately detects pneumoconiotic micronodules and can be used for the interpretation of pneumoconiosis.

mood disorder, and also to draw attention to the diversity of possible symptoms of mood disorders. In general, selective mutism starts at preschool age, although the symptoms are more evident at school age. The importance of an early diagnosis and treatment lies in the prevention of some complications, such as social and academic development and self-esteem, besides the possibility of the development of other anxiety disorders. Bipolar mood disorder is a mental disease characterized by extreme mood variations. In childhood, it hinders the child's emotional growth and development. Selective mutism is mistaken by attention deficit hyperactivity disorder, and behavioral disorders, such as conduct disorder and oppositional defiance disorder. The present case report is about a female patient evaluated at 5 years and 9 months of age. We concluded the case as being a selective mutism disorder. Not only psychotherapy, with parent and school orientation, but also medication was prescribed. The first prescribed medication was use of selective serotonin reuptake inhibitors with good results regarding anxiety symptoms, although the patient started to present significant deterioration in behavior. Because of that, the diagnostic hypothesis came to be bipolar mood disorder with an early start. The patient presented satisfactory evolution only after given a third option of mood stabilizer medication. Selective mutism, which is an anxiety disorder in childhood, can be prodromus to other psychiatric conditions at the same age. It is necessary for pediatricians, who are the doctors that first assess these children, and also child psychiatrists, to be aware of the wealth of symptoms that can give continuation to the condition.

Full Text Available The article analyzes the reports generated by physicians participating in the Comissão de Linhas Telegráficas Estratégicas de Mato Grosso ao Amazonas (CLTEMTA, or Rondon Commission, that labored in these states between 1907 and 1915. The commission had as its objective the construction of telegraph lines to the borders of Brazil with Bolivia and Peru. The construction activity was also accompanied by scientific studies for the 'productive occupation' of the region and by the writing of medical assessments of the region. These assessments of the so called 'northwest hinterlands' (sertões highlighted the region's unhealthy climate and the debilitating impact of malaria. The purpose is to analyze the impact of this disease in the works of the CLTEMTA. Our hypothesis is that one of its main effects was the elaboration of medical studies more and more detailed about the possible causes of diseases in that region.

Full Text Available Aims: To survey current, Danish industrial noise levels and the use of hearing protection devices (HPD over a 10-year period and to characterise the association between occupational noise and hearing threshold shift in the same period. Furthermore, the risk of hearing loss among the baseline and the follow-up populations according to first year of occupational noise exposure is evaluated. Materials and Methods: In 2001–2003, we conducted a baseline survey of noise- and hearing-related disorders in 11 industries with suspected high noise levels. In 2009–2010, we were able to follow up on 271 out of the 554 baseline workers (49%. Mean noise levels per industry and self-reported HPD use are described at baseline and follow-up. The association between cumulative occupational noise exposure and hearing threshold shift over the 10-year period was assessed using linear regression, and the risk of hearing loss according to year of first occupational noise exposure was evaluated with logistic regression. Results: Over the 10-year period, mean noise levels declined from 83.9 dB(A to 82.8 dB(A, and for workers exposed >85 dB(A, the use of HPD increased from 70.1 to 76.1%. We found a weak, statistically insignificant, inverse association between higher ambient cumulative noise exposure and poorer hearing (−0.10 dB hearing threshold shift per dB-year (95% confidence interval (CI: −0.36; 0.16. The risk of hearing loss seemed to increase with earlier first year of noise exposure, but odds ratios were only statistically significant among baseline participants with first exposure before the 1980s (odds ratio: 1.90, 95% CI: 1.11; 3.22. Conclusions: We observed declining industrial noise levels, increased use of HPD and no significant impact on hearing thresholds from current ambient industrial noise levels, which indicated a successful implementation of Danish hearing conservation programs.

The article deals with results of a priori and a posteriori evaluation of occupational risk for workers' health. Categories of a priori occupational risk for workers are estimated as high to very high (intolerable) risk. Findings are that work conditions in nonferrous metallurgy workshop result in upper respiratory tract diseases (medium degree of occupational conditionality). Increased prevalence of such diseases among the workers is connected with length of service. The authors revealed priority factors for occupationally conditioned diseases. A promising approach in occupational medicine is creation of methods to evaluate and forecast occupational risk, that enable to specify goal parameters for prophylactic measures. For example, modelling the risk of occupationally conditioned diseases via changes in exposure to occupational factor and length of service proved that decrease of chemical concentrations in air of workplace to maximally allowable ones lowers risk of respiratory diseases from 14 to 6 cases per year, for length of service of 5 years and population risk.

Development of an artificial intelligence expert system for diagnosing occupational lung disease requires explicit specification of the structure of knowledge necessary in clinical occupational medicine independent of the process by which the knowledge is utilized. Furthermore, explicit recognition of sources of uncertainty is necessary. Seven categories of knowledge define the diagnostic knowledge base in occupational pulmonary medicine. These include four objects (jobs, industries, exposures, and diseases) and three relationships between pairs of objects. This analysis demonstrates some of the unique aspects of occupational medicine expertise.

Occupational physicians should be familiar with the risk factors and clinical presentation of pulmonary thromboembolism (PTE). PTE belongs to the group ofis a cardiovascular diseases, which are the main cause (40%) of death in Spanish workplaces; at present, they may be considered a work-related injury because of the doctrinal evolution in the legal interpretation of the presumption of iuris tantum. We present the case of a hypertensive and obese adult male who suffered a PTE at his workplace. The availability of a portable pulse oximeter (room air SpO2, 92%) was critical in guiding the decision to refer him urgently to the hospital, where the diagnosis was confirmed. We can conclude that, independently of whether this event is later deemed to be work-related (in this case it was not), occupational physicians must know how to correctly manage and refer affected workers.

From the point of view of occupational health, the field of voice disorders is very poorly developed as compared, for instance, to the prevention and diagnostics of occupational hearing disorders. In fact, voice disorders have not even been recognized in the field of occupational medicine. Hence, it is obviously very rare in most countries that the voice disorder of a professional voice user, e.g. a teacher, a singer or an actor, is accepted as an occupational disease by insurance companies. However, occupational voice problems do not lack significance from the point of view of the patient. We also know from questionnaires and clinical studies that voice complaints are very common. Another example of job-related health problems, which has proved more successful in terms of its occupational health status, is the repetition strain injury of the elbow, i.e. the "tennis elbow". Its textbook definition could be used as such to describe an occupational voice disorder ("dysphonia professional is"). In the present paper the effects of such risk factors as vocal loading itself, background noise and room acoustics and low relative humidity of the air are discussed. Due to individual factors underlying the development of professional voice disorders, recommendations rather than regulations are called for. There are many simple and even relatively low-cost methods available for the prevention of vocal problems as well as for supporting rehabilitation.

Many Indian mammals face range contraction and extinction, but assessments of their population status are hindered by the lack of reliable distribution data and range maps. 2. We estimated the current geographical ranges of 20 species of large mammals by applying occupancy models to data from country-wide expert. We modelled species in relation to ecological and social covariates (protected areas, landscape characteristics and human influences) based on a priori hypotheses about plausible determinants of mammalian distribution patterns. 3. We demonstrated that failure to incorporate detection probability in distribution survey methods underestimated habitat occupancy for all species. 4. Protected areas were important for the distribution of 16 species. However, for many species much of their current range remains unprotected. The availability of evergreen forests was important for the occurrence of 14 species, temperate forests for six species, deciduous forests for 15 species and higher altitude habitats for two species. Low human population density was critical for the occurrence of five species, while culturally based tolerance was important for the occurrence of nine other species. 5. Rhino Rhinoceros unicornis, gaur Bos gaurus and elephant Elephas maximus showed the most restricted ranges among herbivores, and sun bear Helarctos malayanus, brown bear Ursus arctos and tiger Panthera tigris were most restricted among carnivores. While cultural tolerance has helped the survival of some mammals, legal protection has been critically associated with occurrence of most species. 6. Synthesis and applications. Extent of range is an important determinant of species conservation status. Understanding the relationship of species occurrence with ecological and socio-cultural covariates is important for identification and management of key conservation areas. The combination of occupancy models with field data from country-wide experts enables reliable estimation of species
This review discusses the contribution of radiology to occupational medicine as well as work-related problems in radiology dept.s. Research issues are emphasized. Radiology has been used especially when diagnosing occupational respiratory and locomotive system problems and solvent-induced encephalo- and hepatopathy. The aim of research in these areas is usually to characterize occupational diseases and to identify physico-chemical hazards in the work place by comparing between groups of workers and non-exposed controls. Radiological imaging allows an objective characterization of the disease, and it may clarify the pathogenesis of the process and provide a useful epidemiological tool. Advanced statistical methods are often needed to adjust analyses for confounding variables. As the diagnostic requirements are increasing, more sensitive and sophisticated radiological methods, such as high-resolution computed tomography, magnetic resonance imaging and magnetic resonance spectroscopy, may be required for the early recognition of occupational health risks. This necessitates good cooperation between occupational health units and well-equipped imaging dept.s. Considering occupational problems in radiology departments, the increasing use of digital radiology requires ergonomic measures to control and prevent locomotive problems caused by work with computers. Radiation protection measures are still worth concern, especially in interventional radiology
