Sample records for care workers exposed

  1. Occupational health care of radiation exposed workers

    International Nuclear Information System (INIS)

    The medical problems encountered by the earlier pioneer workers in radiation at the turn of the century are well known. In the 1928, the ICRP (International Committee for Radiological Protection) was instituted and the ALARA principle of radiation protection was evolved. Occupational health care is about maintaining the health and safety of workers in their workplaces. This involves using medical, nursing and engineering practices to achieve its objectives. In certain occupations, including those where workers are exposed to ionising radiation, some of these principles are enshrined in the legislation and would require statutory compliance. Occupational health care of radiation workers seek to prevent ill health arising from exposure to radiation by consolidating the benefits of exposures control and dosimetry. This is via health surveillance for spillages, contamination and exposures to unsealed sources of radiation. It is unlikely that can plan and hope to cater for a Chernobyl type of disaster. However, for the multitude of workers in industry exposed to radiation, control models are available. These are from the more in industrialize countries with a nuclear based energy industry, and where radioactive gadgetry are used in places ranging from factories and farms to construction sites. These models involve statutory requirements on the standard of work practices, assessment of fitness to work and the monitoring of both the worker and the workplace. A similar framework of activity is present in Malaysia. This will be further enhanced with the development of her general health and safety at work legislation. (author)

  2. Surveillance of health care workers exposed to ionising radiation: Rimed pilot study

    International Nuclear Information System (INIS)

    The project so-called RIMED aimed to set up epidemiological surveillance of health care workers exposed to ionizing radiation. A pilot study was conducted in a sample of hospital personnel to examine the possibility of identifying exposed subjects in order to analyse mortality patterns according to occupational characteristics such as medical departments or occupations in a historical cohort. Seven hospitals participated in this pilot study. Health-care workers who had worn a dosimeter up to December 2003 were to be included in this cohort. The subjects' identification data were obtained from the SISERI (Systeme d'information de la surveillance de l'exposition aux rayonnements ionisants - Ionizing Radiation Exposure Monitoring Information System) database managed by the Institut de radioprotection et de surete nucleaire - Radiation Protection and Nuclear Safety Institute (IRSN). The SISERI system was in a 'pilot' phase in 2004. According to SISERI database, a total of 5126 subjects were found to have worn a dosimeter up to December 2003. The subjects' identification data were completed by the administrative services of the hospitals and occupational physicians searched for subjects' occupational data. Information required for the vital status search was satisfactorily completed only for 38% of the cohort subjects. This pilot study showed that obtaining data from SISERI database completed by hospital administrative data in 2004 led to a database of insufficient quality for epidemiological surveillance. The Institut de veille sanitaire (French Institute of Public Health Surveillance) recommends that transmission by the employers of some specific personal or occupational data of the exposed subjects should be made compulsory. In this way, SISERI system should be able to constitute any database with required quality for epidemiological surveillance of ionizing radiation exposed subjects. (authors)

    Full Text Available The first report of occupational acquisition of HIV appeared in 1984, and, by June, 1997, the Centers for Disease Control and Prevention (CDC had reported 52 documented cases of sero-conversion following occupational exposure to HIV-1 by health care workers of those cases. 47 (90.3% were exposed to blood. The most frequent type of accident reported was percutaneous needlestick injury. Prospective studies have estimated that the risk of HIV transmission following percutaneous exposure to infected blood is 0.3% (Confidence Interval 95% = 0.2% to 0.5%. Following a mucous membrane exposure, the risk is 0.09% (CI 95% = 0.006% to 0.5%. The risk of hepatitis B acquisition ranges from 6% to 30%, and hepatitis C acquisition, 3% to 10%. Since 1992, the São Paulo Hospital's Hospital Infection Prevention and Control Service (SPCIH has notified and treated all workers exposed to accidents involving biological materials. In the last six years, we have handled approximately 1,300 cases of reported accidents, of which 90% were percutaneous, most involving needlesticks. Such cases were frequently caused by the inadequate disposal and recapping of needles. In these accidents, 20% of the source patients were HIV positive, 10% were hepatitis C positive, and 7.6% were hepatitis B positive. This review summarizes the guidelines for a standardized response when dealing with accidents involving health care workers. Transmission of hepatitis B and HIV can be reduced if adequate preventive measures are taken in advance. If proper prophylaxis is not being done, it should be initiated immediately.

  4. Proposal to integrate the service on radiation hygiene at the primary health care services for workers exposed to ionizing radiation

    International Nuclear Information System (INIS)

    The National Health System implemented in the last few years a new pattern of primary attention for workers by creating doctors offices in work centers. At the same time, the Ministry of Public Health (MINSAP) carries the medical surveillance of the staff exposed to ionizing radiation. This work proposes a program to integrate the consulting room on radiation hygiene to primary health care services for workers that work with ionizing radiation sources, aiming to ameliorate and improve them

    Full Text Available OBJECTIVE To assess adherence to clinical appointments by health care workers (HCW and students who suffered accidents with potentially infectious biological material. METHOD A retrospective cross-sectional study that assessed clinical records of accidents involving biological material between 2005 and 2010 in a specialized unit. RESULTS A total of 461 individuals exposed to biological material were treated, of which 389 (84.4% were HCWs and 72 (15.6% students. Of the 461 exposed individuals, 307 (66.6% attended a follow-up appointment. Individuals who had suffered an accident with a known source patient were 29 times more likely to show up to their scheduled follow-up appointments (OR: 29.98; CI95%: 16.09-55.83. CONCLUSION The predictor in both univariate and multivariate analyses for adherence to clinical follow-up appointment was having a known source patient with nonreactive serology for the human immunodeficiency virus and/or hepatitis B and C.

    The aim of this study is to estimate whether the occupational exposure to low dose anesthetic gases could cause alterations of blood parameters in health care workers. 119 exposed subjects and 184 not exposed controls were included in the study. Each worker underwent the complete blood count test (CBC), proteinaemia, leukocyte count, serum lipids, liver and kidney blood markers. The liver blood markers show statistically significant differences in health care workers compared with controls (pGGT, total bilirubin, lymphocytes and neutrophils was statistically significant in health care workers compared with controls (p<0.05). The results suggest that occupational exposure to low dose anesthetic gases could influence some haematochemical hepatic and hematopoietic parameters in exposed health care workers. PMID:24374387

    The risks associated with exposure to inorganic lead and the means by which these risks can be minimized are outlined. Lead is used to make a variety of metal products, the grids and oxides in storage batteries, pigments, chemicals, and also for lead plating. In the United States about 70% of the total lead consumption is related to transportation. Uptake of inorganic lead is by ingestion and inhalation. About 90% of the total body burden of lead is contained within the skeletal tissues. Lead is excreted in the kidney, in sweat, and in milk. Toxic effects are directed against the blood, the nervous system, and the kidney. Symptoms of lead poisoning are abdominal pain, constipation, vomiting, asthenia, paresthesia, psychological symptoms, and diarrhea. Physical and biological monitoring can serve to protect workers. Diagnosis of lead poisoning is not easy. Treatment involves removal from exposure and/or treatment with a chelating agent.

    Eryptosis is a physiological phenomenon in which old and damaged erythrocytes are removed from circulation. Erythrocytes incubated with lead have exhibited major eryptosis. In the present work we found evidence of high levels of eryptosis in lead exposed workers possibly via oxidation. Blood samples were taken from 40 male workers exposed to lead (mean blood lead concentration 64.8 μg/dl) and non-exposed workers (4.2 μg/dl). The exposure to lead produced an intoxication characterized by 88.3% less δ-aminolevulinic acid dehydratase (δALAD) activity in lead exposed workers with respect to non-lead exposed workers. An increment of oxidation in lead exposed workers was characterized by 2.4 times higher thiobarbituric acid-reactive substance (TBARS) concentration and 32.8% lower reduced/oxidized glutathione (GSH/GSSG) ratio. Oxidative stress in erythrocytes of lead exposed workers is expressed in 192% higher free calcium concentration [Ca{sup 2+}]{sub i} and 1.6 times higher μ-calpain activity with respect to non-lead exposed workers. The adenosine triphosphate (ATP) concentration was not significantly different between the two worker groups. No externalization of phosphatidylserine (PS) was found in non-lead exposed workers (< 0.1%), but lead exposed workers showed 2.82% externalization. Lead intoxication induces eryptosis possibly through a molecular pathway that includes oxidation, depletion of reduced glutathione (GSH), increment of [Ca{sup 2+}], μ-calpain activation and externalization of PS in erythrocytes. Identifying molecular signals that induce eryptosis in lead intoxication is necessary to understand its physiopathology and chronic complications. - Graphical abstract: Fig. 1.

  12. Genome stability in radiation exposed workers

    International Nuclear Information System (INIS)

    The radiosensitivity of peripheral blood lymphocytes in 51 occupationally exposed to radiation workers at Kozloduy NPP and 12 control subjects was investigated. In vitro irradiation with 1,5 Gy Cs-137 gamma-rays was used as a challenge dose. The frequency of micronuclei in binucleated lymphocytes was detected before and after in vitro irradiation as a biomarker of radiosensitivity. The data obtained show lower frequency of radiation induced micronuclei in exposed workers compared to the non-exposed controls. Decreased radiosensitivity in peripheral blood lymphocytes of occupationally exposed to radiation subjects is probably due to the phenomenon of adaptive response known to take place at low dose, long time exposures.

    Earlier reports have suggested that exposure to radiation at workplace may induce cytogenetic abnormalities. However, the association between plasma antioxidants and the cytogenetic abnormalities in these patients has not been elucidated till now. Hence, the present study was undertaken to determine the relationship between the cytogenetic abnormalities, plasma antioxidant system, and the radiation exposure levels in men who were occupationally exposed to ionizing radiation. The study included 134 male volunteers, among whom 83 were occupationally exposed to ionizing radiation. Incidence of micronuclei and chromosomal aberration was assessed in lymphocytes. Total and reduced glutathione (GSH), total antioxidant capacity (TAC), superoxide dismutase (SOD), and lipid peroxidation were assessed in the plasma. The micronuclei frequency and chromosomal aberrations were significantly higher in the exposed group in comparison to the nonexposed group (P stress to protect somatic cell genetic integrity.

    A group of 50 workers, exposed for an average of 2.77 years in an environment, samples of which contained from 46 to 4700 ppm of trichlorotrifluoroethane (Freon 113), was examined. There were no subjective complaints, other than one case of dryness of the skin, referable to this occupational exposure. At this time, it is our opinion that there is no evidence of adverse effects from exposure to trichlorotrifluoroethane under the conditions encountered by these personnel. We believe that continued, periodic, follow-up examinations of these workers will be helpful in further evaluating any possible long-range effects of this material.

    Fluorescence in situ hybridization (FISH) is a powerful new technique that allows numerical chromosome aberrations (aneuploidy) to be detected in interphase cells. In previous studies, FISH has been used to demonstrate that the benzene metabolites hydroquinone and 1,2,4-benzenetriol induce aneuploidy of chromosomes 7 and 9 in cultures of human cells. In the present study, we used an interphase FISH procedure to perform cytogenetic analyses on the blood cells of 43 workers exposed to benzene (median=31 ppm, 8-hr time-weighted average) and 44 matched controls from Shanghai, China. High benzene exposure (>31 ppm, n=22) increased the hyperdiploid frequency of chromosome 9 (p<0.01), but lower exposure (<31 ppm, n=21) did not. Trisomy 9 was the major form of benzene-induced hyperdiploidy. The level of hyperdiploidy in exposed workers correlated with their urinary phenol level (r= 0.58, p < 0.0001), a measure of internal benzene close. A significant correlation was also found between hyperdiploicly and decreased absolute lymphocyte count, an indicator of benzene hematotoxicity, in the exposed group (r=-0.44, p=0.003) but not in controls (r=-0.09, P=0.58). These results show that high benzene exposure induces aneuploidy of chromosome 9 in nondiseased individuals, with trisomy being the most prevalent form. They further highlight the usefulness of interphase cytogenetics and FISH for the rapid and sensitive detection of aneuploidy in exposed human populations. 35 refs., 3 figs., 2 tabs.

    Multi-walled carbon nanotubes (MWCNT) with their unique physico-chemical properties offer numerous technological advantages and are projected to drive the next generation of manufacturing growth. As MWCNT have already found utility in different industries including construction, engineering, energy production, space exploration and biomedicine, large quantities of MWCNT may reach the environment and inadvertently lead to human exposure. This necessitates the urgent assessment of their potential health effects in humans. The current study was carried out at NanotechCenter Ltd. Enterprise (Tambov, Russia) where large-scale manufacturing of MWCNT along with relatively high occupational exposure levels was reported. The goal of this small cross-sectional study was to evaluate potential biomarkers during occupational exposure to MWCNT. All air samples were collected at the workplaces from both specific areas and personal breathing zones using filter-based devices to quantitate elemental carbon and perform particle analysis by TEM. Biological fluids of nasal lavage, induced sputum and blood serum were obtained from MWCNT-exposed and non-exposed workers for assessment of inflammatory and fibrotic markers. It was found that exposure to MWCNTs caused significant increase in IL-1β, IL6, TNF-α, inflammatory cytokines and KL-6, a serological biomarker for interstitial lung disease in collected sputum samples. Moreover, the level of TGF-β1 was increased in serum obtained from young exposed workers. Overall, the results from this study revealed accumulation of inflammatory and fibrotic biomarkers in biofluids of workers manufacturing MWCNTs. Therefore, the biomarkers analyzed should be considered for the assessment of health effects of occupational exposure to MWCNT in cross-sectional epidemiological studies. PMID:26902652

    Full Text Available Acrylamide (ACR is a water-soluble chemical used in different industrial and laboratory processes. ACR monomer is neurotoxic in humans and laboratory animals. Subchronic exposure to this chemical causes neuropathies, hands and feet numbness, gait abnormalities, muscle weakness, ataxia, skin and in some cases, cerebellar alterations. ACR neurotoxicity involves mostly the peripheral but also the central nervous system, because of damage to the nerve terminal through membrane fusion mechanisms and tubulovescicular alterations. Nevertheless, the exact action mechanism is not completely elucidated. In this paper we have reviewed the current literature on its neurotoxicity connected to work-related ACR exposure. We have analyzed not only the different pathogenetic hypotheses focusing on possible neuropathological targets, but also the critical behavior of ACR poisoning. In addition we have evaluated the ACR-exposed workers case studies. Despite all the amount of work which have being carried out on this topic more studies are necessary to fully understand the pathogenetic mechanisms, in order to propose suitable therapies.

    2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been shown to inhibit uroporphyrinogen decarboxylase activity resulting in chronic hepatic porphyria. From a cross-sectional study of 170 workers in chemical industry 68 showed elevated coproporphyrin levels, interpreted as secondary coproporphyrinuria. Three persons suffered from chronic hepatic porphyria in subclinical stages. None of the workers showed an overt porphyria cutanea tarda. A low-grade zinc protoporphyrinemia was observed in three persons. Forty-three of the 170 workers were evaluable for investigating the effect of TCDD on porphyrin levels. No significant correlation was found between TCDD concentration in adipose tissue and the level of uroporphyrin and coproporphyrin. The influence of a chloracne history is described. (orig.)

  6. Internal Dosimetric Calculations for Occupationally Exposed Workers

    International Nuclear Information System (INIS)

    The Internal radiation dosimetry calculations are very important to estimate the benefit and the risk of radiation in nuclear medicine field for both patient and worker. MIRD scheme and ICRP model have valid methods in this type of calculations. In this work, a new program called WIRDST the Workers Internal Radiation Dosimetry Simulation for Thyroid gland has been built up by using the Monte Carlo (MC) method to simulate the internal exposure of sodium iodide by inhalation for workers. The working conditions have been taken as the same as found in the hot laboratory of nuclear medicine unit in the National Cancer Institute in Cairo University. The point source equivalent model as a parameterization equation has developed newly by using the fitting model of MC method for uniform distribution of radioactive sodium iodide in the thyroid gland. This model is used for the first time in this type of calculation, and then applied on 3 D coordinates of mathematical geometry for the adult phantom of the reference man. The latest parameters (anatomical data and inhalation metabolic data) of ICRP pamphlets and recommendations have been used in this purpose. Moreover, the latest scheme for iodine decay mode and the latest geometry model for thyroid gland are used also. The results showed that the specific effective energy and the effective dose decrease from the thyroid gland to the nearest organs then decrease gradually until terminated in the organs that have large distance from the thyroid. The Annual Limit of Intake (ALI) has been calculated for a wide range of thyroid uptake (5%, 15%, 25%, 35%, 45%, and 55%) in addition to change of the working time order per week in one year. The results showed that the critical point of intake limits are decreased when the thyroid uptake is increased and/or the number of working time in the hot laboratory per week is increased

    Full Text Available Objective: To assess cataract incidence in the cohort of workers occupationally exposed to prolonged radiation. Material and Methods: Cataract incidence was studied in the cohort of workers of the first Russian nuclear enterprise — the Mayak, who were firstly employed at one of the main facilities (reactors, radiochemical and plutonium production plants in 1948‑1958 and followed up to the end of 2008 (12210 persons. Total of 3100 cataract cases were registered in the study cohort. All cataract cases were reviewed and verified by experts; the study included only confirmed senile cataracts. All workers of the study cohort were exposed to external gamma-rays; mean cumulative dose from external gamma-rays was 0.91±0.01 Gy in males and 0.65±0.01 Gy in females. Statistical analysis provided non-standardized and standardized incidence rates per 100 000 workers. Standardization by sex and age was performed by indirect method using internal reference.Results: 2523 cases of senile cataract were included in the study. Mean age of cataract diagnosis was 62.88±0.26 years in males and 64.88±0.28 years in females. Standardized incidence rates of cataract in females were significantly higher as compared to males and increased with workers age. Comparison between the subcohorts of workers with / without diagnosed cataracts demonstrated that among workers with cataracts the proportions of the following groups of workers were significantly higher: workers employed before 1954; workers employed at reactors; smoking workers; workers with the smoking index exceeding 20 pack*years; workers who consumed alcohol; workers with excessive body weight; workers with glaucoma and arterial hypertension. Moreover the mean cumulative dose from external gamma-rays and / or neutron exposure was significantly higher in the subcohort of workers diagnosed with cataracts than that in the subcohort of workers free of the disease.

    A pharmaceutical worker developed asthma when exposed to hydralazine, an antihypertensive drug. The diagnosis of occupational asthma was supported by specific inhalation challenges, which produced a late asthmatic reaction and an increase in bronchial responsiveness. No evidence of an IgE or an IgG dependent mechanism could be found.

    OBJECTIVES: The aim of this study was to investigate the possibility of subtoxic exposure to pesticides causing chromosome aberrations in greenhouse workers. METHODS: In a cross-sectional and prospective study design chromosome aberration frequencies in cultured lymphocytes were examined for 116...... greenhouse workers exposed to a complex mixture of almost 50 insecticides, fungicides, and growth regulators and also for 29 nonsmoking, nonpesticide-exposed referents. RESULTS: The preseason frequencies of chromosome aberrations were slightly but not statistically significantly elevated for the greenhouse...... workers when they were compared with the referents. After a summer season of pesticide spraying in the greenhouses, the total frequencies of cells with chromosome aberrations were significantly higher than in the preseason samples (P=0.02) and also higher than for the referents (P=0.05). This finding was...

  13. Screening and surveillance of workers exposed to mineral dusts

    Energy Technology Data Exchange (ETDEWEB)

    Wagner, G.R.

    1997-12-31

    This publication resulted from a World Health Organisation initiated project to investigate the harmonisation of definitions, approaches and methodologies for the screening and surveillance of workers exposed to mineral dust. The first part of the book provides definitions of screening and surveillance and describes the main elements of such programmes. The second part discusses the practical aspect of the screening and surveillance of working populations exposed to crystalline silica, coal mine dust and asbestos. Although no single set of guidelines is applicable to the development and implementation of a programme for the screening and surveillance of workers exposed to mineral dust, the recommendations, together with certain caveats, should provide a useful starting point. Annexes provide examples of existing programmes in various countries and environments and discuss the use and interpretation of questionnaires, lung spirometry and chest radiography. Overall the book should be of interest to occupational health professionals.

    the same time it illustrates the care workers' commitment to the elderly. A paradoxical "empathy at a distance" is characteristic of the scene. When analyzing my written observations in an interpretation group, my use of language was a point of discussion. What did it mean when I described the...... interactions between care workers and elderly residents in words commonly used to describe mother-child interactions? My use of language became a "hermeneutical key" which enabled a psychoanalytically inspired interpretation. This focuses on the care relationship as activating our earliest memories of our own...... care relations, independently of whether we are in the role of care providers or care receivers. Through collusion theory, the interpretation accepts both the anxiety which the helpless elderly people arouse in the care workers and their motivation for care work as two sides of a subjectively important...

  15. PREVALENCE OF VARIOUS MUSCULOSKELETAL DISORDERS IN CHILD CARE WORKERS IN DAY CARE SETTINGS

    Directory of Open Access Journals (Sweden)

    Mariet Caroline, MPT,

    2014-08-01

    Full Text Available Child care workers are those who take care of children in the absence of their parents. Child care workers are exposed to various kinds of occupational injuries which include infections, sprains and strains, trauma like bites from children, trip falls and noise exposure. The risks of injury among these workers are due to their nature of the job. One of the common occupational risks found in these workers is musculoskeletal injury, it occurs as a result of working in awkward postures such as bending, twisting, lifting and carrying in incorrect positions, which may result in various injuries like strain, sprain and soft tissue ruptures. Workers with poor physical conditioning may tend to undergo these changes very rapidly. The purpose of this study was to find out the prevalence of various musculoskeletal disorders in child care workers who are taking care of the babies. The study was conducted around various day care centres, among 160 women from who were chosen for the study and were given musculoskeletal analysis questionnaires (Nordic musculoskeletal questionnaire , The Questionnaires were evaluated using descriptive statistics, analysed using SPSS and the results were computed in percentage. Following the analysis, it was concluded that low back injury was predominant among 44% of workers followed by 18% with neck pain, 11% of shoulder pain, 9% of knee pain, 7% of elbow, 6% of wrist, 4% of others and surprisingly 1 % had no musculoskeletal complaints.

    2013-02-01

    Full Text Available OBJECTIVE: To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS: Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8,000 Hz, to investigate the peripheral auditory system; the Random Gap Detection test, to assess the central auditory system; and the Amsterdam Inventory for Auditory Disability and Handicap, to investigate subjects' self-reported hearing performance in daily-life activities. A Student t test and analyses of covariance (ANCOVA were computed to determine possible significant differences between solvent-exposed and non-exposed subjects for the hearing level, Random Gap Detection test and Amsterdam Inventory for Auditory Disability and Handicap. Pearson correlations among the three measures were also calculated. RESULTS: Solvent-exposed subjects exhibited significantly poorer hearing thresholds for the right ear than non-exposed subjects. Also, solvent-exposed subjects exhibited poorer results for the Random Gap Detection test and self-reported poorer listening performance than non-exposed subjects. Results of the Amsterdam Inventory for Auditory Disability and Handicap were significantly correlated with the binaural average of subject pure-tone thresholds and Random Gap Detection test performance. CONCLUSIONS: Solvent exposure is associated with poorer hearing performance in daily life activities that relate to the function of the peripheral and central auditory system.

    Background Previous studies suggest that welders frequently display parkinsonian signs, such as bradykinesia and tremor. Demonstrating that these parkinsonian findings are associated with reductions in quality of life (QoL) or health status could have important repercussions for worker safety and performance. Methods Subjects included 394 active workers exposed to welding fumes and evaluated for parkinsonism by movement disorders experts in a worksite-based epidemiology study. Subjects were diagnosed with parkinsonism if the Unified Parkinson Disease Rating Scale motor subsection part 3 (UPDRS3) score was >15. All subjects completed a Parkinson’s disease (PD) symptom questionnaire and the PDQ39, a widely used QoL and health status measure for PD. Results Total PDQ39 score and all subscores were greater in welders with parkinsonism than welders without parkinsonism, with the most significant differences observed for mobility, emotional well-being, and activities of daily living (ADL’s). The PDQ39 scores for welding exposed workers with parkinsonism were similar to scores seen in a group of early PD patients. Conclusion Parkinsonism in active, welding exposed workers is associated with reductions in health status and QoL affecting a broad range of categories and within the range seen in early PD.

  18. Evaluation of radiation protection educational level of professional exposed workers

    International Nuclear Information System (INIS)

    Full text: Serbia and Montenegro legislation concerning with radiation protection was upgrading after publication ICRP- 60 and B.S.S., No.115. Present Law on the Protection against Ionizing Radiation is in force from 1996. Among quite new issues in radiation protection regulations there was article relate to obligatory refresher training. Due to adverse political and economic situation through many years radiation protection regulations were not fulfill completely. The aim of this investigation was to get real view to education level of professional exposed workers. In Serbia and Montenegro the most of ionizing radiation sources are in medical use and the most exposed workers are radiographers and radiologists. The test was passed by 200 radiographers and 50 radiologists. Main groups of questions were: Radiation protection and safety; difference between safety and security; legislation: law and regulations; incidents, accidents and operational failures: recording, learning. Usually, knowledge from school pales. New quantities (as ambient and personal dose equivalent) are mostly unknown. It is easier to understand the real difference between safety and security than to understand linguistic differences. Discussing regulations workers are more interesting in syndicate regulations than radiation protection ones. Operational failures and incidents are hidden. Better to say: nobody dare to speak about them. The results imposed conclusion that regulatory body has to pay more attention to upraise safety culture and radiation protection education level of professional exposed workers. (authors)

    Full Text Available Objectives: Epidemiological studies provide evidence that airborne particulate matter may contribute to the increased incidence and mortality rates due to pulmonary and cardiovascular diseases. Only some of them address the problem of occupational exposure to particulate air pollution. The aim of our study was to assess cardiovascular reaction and autonomic regulation in workers exposed to fine particles. Materials and Methods: All workers had medical examination, resting ECG with heart rate variability analysis (HRV, 24-h ECG, and ambulatory blood pressure monitoring (ABPM performed. The subjects were 20 male workers (mean age: 32.14.0 year of a ceramic ware factory exposed to the dust and 20 workers who were not exposed (mean age: 39.4±7.8 year. The period of employment under exposure amounted to 5.6±2.1 year. Dust exposure was measured using individual dosimeters. Results: The geometric mean total dust concentration was 44±1.5 mg/m3 and the FPD (fine particulate dust concentration amounted to 11.5±1.6 mg/m3. No abnormalities were noted in the resting ECG in both groups, in 24-h ECG 2 subjects, both from exposed and control groups, had ventricular heart rhythm and repolarization disturbances. Blood pressure in ABPM, both systolic as well as diastolic, was normal and did not differ between the groups. Resting heart rate in the exposed group was significantly lower (p = 0.038 than in the control group. In the exposed group STD R-R from short-term records was significantly higher (p = 0.01. Fast Fourier Transform (FFT analysis showed that the low frequency power spectrum (LF did not differ in the exposed and the control group, while high frequency (HF was significantly higher in the exposed group. LF/HF ratio was significantly lower in the exposed in comparison with the control group. Conclusions: Although we did not reveal significant abnormalities in ECG as well as in ABPM in the exposed group, it seems that neurovegetative disturbances

    Objective: A rapid diagnosis method was developed to detect Rubella virus infection in radiation workers. Methods: Modified ELISA method was used to detect the level of lgG and lgM antibodies in 514 in Jinan district. Results: 90.47% of 514 cases was shown to be resistant against Rubella virus; 6.42% were sensitive type; 0.78% belonged to be reinfected. Conclusion: Detection of Rubella virus in exposed radiation workers was imperative, and vaccine against Rubella virus was also needed to eliminate the infection risk. (authors)

  1. Lung scintigraphy evaluation in workers exposed to abrasive dusts

    International Nuclear Information System (INIS)

    The production process of abrasives use aluminium, or silicon carbide a synthetic material with a hardness only slightly less than that of a diamond. It is popularly known as carborundum since it was first manufactured as an abrasive in 1891, produced by the fusion of high grade silica and petroleum coke with sawdust. For many years silicon carbide was thought not to give rise to pulmonary lesions. Recently several researchers suggested the existence of a carborundum pneumoconiosis. The aim of this study was to evaluate the role of the pulmonary clearance of 99m Technetium chelated to diethylene-triamine penta-acetate (99m Tc DTPA), and 67 Gallium lung scanning in workers exposed to abrasive dusts. Thirty seven subjects, 13 smokers and 24 nonsmokers and ex smokers were studied. In 32 (86,48%) 67 Gallium lung scanning was positive including 13 (40,62%) retired workers. We conclude that non smoking workers of abrasives plants have a pulmonary alveolar epithelial permeability disturbance similar as observed in smoking workers and smoking controls. Most workers, ex-workers of these industries and in patients with carborundum pneumoconiosis there is an evidence of pulmonary inflammation measured with abnormal 67 Gallium lung scan. (author)

  2. Studies on chromosome aberrations in workers occupationally exposed to radiation

    International Nuclear Information System (INIS)

    Cytogenetic assays for unstable chromosomes were performed on 54 medical radiation workers who are occupationally exposed to radiation and 42 controls. A total of 15,577 metaphase cells were scored. The frequencies of dicentrics and acentric chromosomes on controls were 0.52*10-3 and 0.82*10-2, respectively. On radiation workers those were 2.28*10-3 and 1.34*10-2, respectively. Though the frequencies of all types of chromosome aberrations in the workers were higher than those in the controls, the only significant difference was found in the case of dicentrics (P 0.05) except exposure dose of recent one year (P < 0.05). These results could indicate that low level exposure to ionizing radiation can induce unstable chromosome aberrations in blood lymphocytes

  3. Granulocytes enzymes as a biomarker of radiotoxicity in exposed workers

    International Nuclear Information System (INIS)

    When radionuclide reaches the organism it causes internal irradiation and the lesions may be long lasting in various tissues. Enzymes in leukocytes will be used as a biomarkers of contamination with radio-nuclide in nuclear medicine workers. The analysed group had been consisted of 74 workers, exposed to radioactive isotopes J 131 and mTc 99 in nuclear medicine. Duration of occupational exposure (DOE) varied, so the groups with DOE of 1-5, 6-15, and 16-30 years, were compared to one another. The control group consisted of 52 subjects exposed to radionuclides (Cs137) from environmental. Alkaline phosphatases and myeloperoxidase activity were inhibited in the granulocytes. The neutrophilic granulocytes count was lower while the number of eosinophils was higher

  4. Chest X ray examination of workers exposed to pneumoconiosis risk

    International Nuclear Information System (INIS)

    Chest X-ray examination of workers exposed to pneumoconiosis risk: critical analysis of legal and radiation protection aspects. Chest X-ray examination is one of the most common radiological examinations practised in Italy. According to Presidential Decree 1124/65, workers exposed to risk of asbestosis and silicosis must undergo a chest radiography once a year, on occasion of the periodic medical examination. Basic requirements aimed at the radiation protection of the patient must therefore be complied with, and optimization of the chest radiography execution procedures is required. This paper illustrates the results obtained with the implementation of the NEXT programme in Italy for this kind of X-ray examination. The main objective of the NEXT programme is the optimization of radiological techniques. On the basis of the most recent publications in the field of radiation protection, a critical analysis is made of the laws in force in Italy

    In Poland, the use of asbestos was banned in 1997 and asbestos plants have been closed since then. Despite their closure, cases of asbestos-related occupational diseases among former asbestos workers are still being recorded in the Central Register of Occupational Diseases. Between 2001 and 2014, there were 2726 asbestos-related illnesses, classified and reported as diseases associated with occupational exposure to asbestos. In 2000, Poland introduced a programme called Amiantus, targeted at former asbestos-processing plant workers. The programme provided periodic medical examinations to workers and free access to medications for treatment of asbestos-related illnesses. Introduction of the programme provided additional data to generate a reliable estimation of the number of asbestos-related occupational diseases, including cancer. The average latency period for asbestosis, lung cancer and mesothelioma is about 40 years so there may still be some health impact to former workers necessitating follow-up. We present the Polish experience of implementing a medical examination programme for asbestos-exposed workers and provide a list of activities to consider when planning for such a programme.

    Full Text Available Objectives. To study the associations between exposure to bioaerosols and work-related symptoms, lung function and biomarkers of airway inflammation in compost workers. Materials and method. Personal full-shift exposure measurements were performed on 47 workers employed at five windrow plants (n=20 and five reactor plants (n=27. Samples were analyzed for endotoxins, bacteria, fungal and actinomycetes spores. Health examinations were performed on workers and 37 controls before and after work on the day exposure was measured. The examinations included symptoms recorded by questionnaire, lung function by spirometry and nasal dimensions by acoustic rhinometry (AR. The pneumoproteins CC16, SP-D and SP-A were measured in a blood sample drawn at the end of the day. Results. The levels of endotoxins (median 3 EU/m[sup]3[/sup] , range 0–730 EU/m[sup]3[/sup] and actinomycetes spores (median 0.2 × 10[sup]6[/sup] spores/m[sup]3[/sup] , range 0–590 × 10[sup]6[/sup] spores/m[sup]3[/sup] were significantly higher in reactor plants compared to windrow plants. However, windrow composting workers reported more symptoms than reactor composting workers, probably due to use of respiratory protection. Exposure-response relationships between actinomycetes spores exposure and respiratory effects, found as cough and nose irritation during a shift, was significantly increased (OR 4.3, 95% CI 1.1–16, OR 6.1, 95% CI 1.5–25, respectively, p<0.05 among workers exposed to 0.02–0.3 × 10[sup]6[/sup] actinomycetes spores/m 3 , and FEV1/FVC% decreased cross shift (b=–3.2, SE=1.5%, p<0.01. Effects were weaker in the highest exposed group, but these workers used respiratory protection, frequently limiting their actual exposure. No relationships were found between exposure and pneumoprotein concentrations. Conclusions. The major agent in the aerosol generated at compost plants was actinomycetes spores which was associated with work related cough symptoms and work

    1990-01-01

    A 30 year-old male polyurethane worker was exposed to an accidental spill of 4,4'-methylene-bis-2-chloroaniline (MBOCA) at a plant producing MBOCA-cured plastic products. Exposure to MBOCA is significant in that this compound is a known animal carcinogen and a suspected human carcinogen. The employee was sprayed over his upper body and extremities with molten MBOCA while cleaning out a clogged hose from a MBOCA and polymer mixing machine. The subsequent environmental and medical evaluation of this episode included serial urinary MBOCA samples from the worker over a 2 week period to allow the calculation of a biological half-life for this compound. This worker experienced a very high dose of MBOCA as judged by his urinary MBOCA levels (peak value of 1,700 ppb 4 hours after exposure). There were no acute symptoms or other laboratory abnormalities noted. The kinetic evaluation resulted in a biological half-life for MBOCA in urine of approximately 23 hours. Assuming a one-compartment model, approximately 94% of an initial MBOCA dose will be eliminated within four days. This is the first report of kinetic analysis on urinary MBOCA excretion in humans. This information suggests that biological monitoring of the urine MBOCA concentrations in exposed workers may miss peak levels following an acute exposure unless the analyses of the urinary MBOCA are performed in a timely fashion. Recommendations to the company included: 1) installation of a warning system or lock-out device on the mixing machine to prevent the opening of the MBOCA hose prior to the release of pressure; and 2) annual medical surveillance of this individual for bladder cancer with urinalysis and urine cytology.

    Full Text Available  SUMMARYThe P300 component of the auditory event-related brain potential was examined in a group of 11workers exposed to low levels of organic solvents in a paint factory and 11 unexposed controls beforeand after 3 weeks of summer vacation. The P300 latency time was found to be prolonged among theexposed workers compared to the reference group before the summer vacation, and to be significantlylonger before the vacation than after in the exposed group.The P300 component was also examined in a group of 85 seamen from chemical tankers, experiencingpeak exposures to organic solvents. They were compared to a reference group of unexposedseamen. Comparing these two groups, no difference was found in the P300 latency time. No relationshipbetween the P300 latency time and exposure was found in a multiple regression analysis, includingthe variables age, alcohol consumption, smoking and cerebral concussions.The study indicates the occurrence of an acute biological effect in the nervous system related toorganic solvent exposure, expressed by prolonged P300 latency time. This was found at very lowexposure levels and should be studied further.

  11. Genotoxic damage in pathology anatomy laboratory workers exposed to formaldehyde

    International Nuclear Information System (INIS)

    Formaldehyde (FA) is a chemical traditionally used in pathology and anatomy laboratories as a tissue preservative. Several epidemiological studies of occupational exposure to FA have indicated an increased risk of nasopharyngeal cancers in industrial workers, embalmers and pathology anatomists. There is also a clear evidence of nasal squamous cell carcinomas from inhalation studies in the rat. The postulated mode of action for nasal tumours in rats was considered biologically plausible and considered likely to be relevant to humans. Based on the available data IARC, the International Agency for Research on Cancer, has recently classified FA as a human carcinogen. Although the in vitro genotoxic as well as the in vivo carcinogenic potentials of FA are well documented in mammalian cells and in rodents, evidence for genotoxic effects and carcinogenic properties in humans is insufficient and conflicting thus remains to be more documented. To evaluate the genetic effects of long-term occupational exposure to FA a group of 30 Pathological Anatomy laboratory workers was tested for a variety of biological endpoints, cytogenetic tests (micronuclei, MN; sister chromatid exchange, SCE) and comet assay. The level of exposure to FA was evaluated near the breathing zone of workers, time weighted average of exposure was calculated for each subject. The association between the biomarkers and polymorphic genes of xenobiotic metabolising and DNA repair enzymes was also assessed. The mean level of exposure was 0.44 ± 0.08 ppm (0.04-1.58 ppm). MN frequency was significantly higher (p = 0.003) in the exposed subjects (5.47 ± 0.76) when compared with controls (3.27 ± 0.69). SCE mean value was significantly higher (p < 0.05) among the exposed group (6.13 ± 0.29) compared with control group (4.49 ± 0.16). Comet assay data showed a significant increase (p < 0.05) of TL in FA-exposed workers (60.00 ± 2.31) with respect to the control group (41.85 ± 1.97). A positive correlation was

  13. Cataracts in retired actinide-exposed radiation workers

    International Nuclear Information System (INIS)

    Radiation-induced cataracts are predominantly of the posterior sub-capsular (PSC) type, whereas about 90% of age-related cataracts are of other types. Retired workers, likely to have transuranic body burdens, from three DOE-supported installations were questioned regarding their eye-care history and asked for permission to contact their eye-care providers regarding any cataracts. In 97 cases with lifetime exposure records 20 cases (20.6%) were reported to have PSC cataracts. However, of 24 individuals with recorded lifetime doses of 200-600 mSv, nine (37.5%) had PSC cataracts, compared with 15.1% of 73 cases with doses of less than 200 mSv.

    International Nuclear Information System (INIS)

    A PET-Centre is jointly run with the technical university Dresden (TUD) at the research location Rossendorf. The deployed, short-lived positron emitters are also produced on the location. Apart from the medical applications extensive research projects take place. Workers in this area are occupationally exposed. About 35 persons which are directly involved in the production, processing and application of the radioactive substances, are monitored by official film dosimeters organised by the department of radiation protection-person / Incorporation Surveillance Station. In addition to the workers from the research centre, those operating in the PET-centre of the TUD are routinely monitored by means of operational, self-reading dosimeters, partial-body dosimeters (hands) and incorporation surveillance. The corresponding working areas require well adapted monitoring methods. While direct radiation is the main contributor to the exposure during the production process in the PET-Cyclotron (film dosimeter values), the main attention during the processing and application has to be focussed on partial-body exposure. Investigations on the local distribution of exposure confirmed a conversion factor 2 between dosimeter location and site of greatest exposure as derived in former in previous investigations. Continued repeated operations can cause exposures close to the dose limit of 500 mSv for the hands. According to experiences up to now, incorporations (determined both by random measurements and measurements after interventions, semi-annually at the accelerator) will cause negligible contributions to the exposure in the routine operation.

  15. Cytogenetic monitoring of nuclear workers occupationally exposed to ionising radiation

    International Nuclear Information System (INIS)

    Chromosome aberration (CA) analysis using Giemsa techniques was performed in blood lymphocytes of 84 nuclear workers with cumulative doses of 1-632 mSv during employment periods of 1-25 y. The control group comprised 82 healthy male donors. An estimated CA frequency in the total radiation-exposed group was significantly higher when compared with the controls (2.27 vs. 1.76 CA/100 cells, p 0.05). However, significant increase in the total CA frequency was determined in workers with additional internal exposure (2.54 CA/100 cells, p < 0.05) and those with registered neutron doses (2.95 CA/100 cells, p < 0.01). No correlation was found between CA frequency and occupational exposure dose. Borderline significant correlation was found between duration of employment and total CA (r = 0.218, p = 0.046, Fig. 2) and chromosome-type aberration (r = 0.265, p = 0.015) frequency. (authors)

    Full Text Available "nBackground: Crystalline silica may act as an immune adjuvant to increase inflammation and antibody production. The high­est exposures to silica are known to occur in the dusty trades industries such as stone- cutting. We undertook this popula­tion based study to examine the association between occupational silica exposure and humoral immune system."nMethods: In this historical cohort study, 47 workers from 10 stone-cutting factories in Rey City, south of Tehran, Iran  that had more than 10 years exposure  to silica were included in case group and 45 individual without any exposure to silica were selected for control group. We measured serum immunoglobulins (IgM, IgG, and IgA of participants with ELISA method and compared the results between exposed workers and control groups."nResults: The mean concentrations of two immunoglobulines (IgG, IgA and IgM in case group in comparison with control group were higher and lower respectively but both were in normal range. IgA concentration between two groups was statisti­cally significant (P< 0.05."nConclusion: Crystalline silica exposure may promote the humoral immune system in some individuals. Additional research is recommended in other population, using study design that minimize potential selection bias and maximize the quality of expo­sure assessment.

  17. Psychophysical Evaluation of Achromatic and Chromatic Vision of Workers Chronically Exposed to Organic Solvents

    International Nuclear Information System (INIS)

    The purpose of this paper was to evaluate achromatic and chromatic vision of workers chronically exposed to organic solvents through psychophysical methods. Thirty-one gas station workers (31.5 ± 8.4 years old) were evaluated. Psychophysical tests were achromatic tests (Snellen chart, spatial and temporal contrast sensitivity, and visual perimetry) and chromatic tests (Ishihara's test, color discrimination ellipses, and Farnsworth-Munsell 100 hue test FM100). Spatial contrast sensitivities of exposed workers were lower than the control at spatial frequencies of 20 and 30 cpd whilst the temporal contrast sensitivity was preserved. Visual field losses were found in 10-30 degrees of eccentricity in the solvent exposed workers. The exposed workers group had higher error values of FM100 and wider color discrimination ellipses area compared to the controls. Workers occupationally exposed to organic solvents had abnormal visual functions, mainly color vision losses and visual field constriction

    Nickel (Ni) and Ni compounds are widely present in the urban air. The purpose of this study is to estimate exposure of individuals to Ni and the correlation between this exposure and the values of blood counts in outdoor workers. This study focused on a sample of 101 outdoor workers (55 male and 46 female; 65 nonsmokers and 36 smokers), all employed in the municipal police in a large Italian city. The personal levels of exposure to Ni were assessed through (a) environmental monitoring of Ni present in the urban air obtained from individual samples and (b) biological monitoring of urinary and blood Ni. The blood count parameters were obtained from the hemochromocytometric tests. Pearson correlation coefficients (r) were calculated to assess the association between the blood and urinary Ni and the complete blood count. Multiple linear regression models were used to examine the associations between the complete blood count and the independent variables (age, gender, years of work for current tasks, cigarette smoking habit (current and never smoker), values of airborne Ni, and blood and urinary Ni). Multiple linear regression analysis performed on the total group of 101 subjects confirms the association among the red blood cells count, the hematocrit, and the urinary Ni (R(2) = 0.520, p = 0.025 and R(2) = 0.530, p = 0.030). These results should lead to further studies on the effects of Ni in working populations exposed to urban pollutants. The possibility that the associations found in our study may be partially explained by other urban pollutants (such as benzene, toluene, and other heavy metals) not taken into consideration in this study cannot be ruled out.

    By multilayer spiral low-dose computed tomography (LD-CT) of the chest this study assesses the early detection of lung lesions on a sample of 100 traffic policemen of a big Italian city professionally exposed to urban pollutants and 100 controls non-occupationally exposed to urban pollutants matched by sex, age, length of service and cigarette smoking habit. Exposure to urban pollutants in traffic policemen was characterized using the annual average concentrations of PM{sub 10}, NO{sub 2} and benzene in the period 1998-2008 measured by fixed monitoring stations located in different areas of the city. A significant and increasing number of suspicious lung nodules with diameters between 5 and 10 mm was observed: in traffic policemen (including smokers and non-smokers) vs. controls (including smokers and non-smokers); in total smokers (including traffic policemen and controls) vs. total non-smokers (traffic policemen and controls); in smoker traffic policemen vs. smoker controls and vs. non-smoker traffic policemen; in non-smoker traffic policemen vs. non-smoker controls. The RR of finding cases with at least one lung nodule with diameters between 5 and 10 mm in traffic policemen (including smokers and non-smokers) compared to controls (including smokers and non-smokers) is 1.94 (CI 1.13-3.31); in total smokers vs. non-smokers the RR is 1.96 (CI 1.20-3.19). The comparison between the interaction exposure and smoking shows an increase in smoker traffic policemen than in smoker controls (RR=2.14; CI 1.02-4.52). The RR for smoker traffic policemen was higher than in non-smoker traffic policemen (RR=2.09; CI 1.19-3.66). The results of our study show that: (1) while smoker workers have a higher risk for developing solid suspicious lung nodules, the simple routinely exposure to urban pollutants is unable to produce the same kind of increased risk; (2) the interaction of smoking and exposure to urban pollutants greatly increases the risk for the development of solid

  20. Coal worker's pneumoconiosis: CT assessment in exposed workers and correlation with radiographic findings

    International Nuclear Information System (INIS)

    To study the signs of coal worker's pneumoconiosis (CWP) at computed tomography (CT), the authors obtained thoracic CT scans in 170 coal-dust-exposed workers who were concomitantly evaluated with conventional posteroanterior and lateral radiography. The profusion and extent of disease was assessed by means of CT in two groups of miners: group 1 (n = 86), miners with worker's compensation and radiographic evidence of CWP, and group 2(n = 84), miners who had applied for compensation without radiographic evidence of CWP. The CT signs of CWP consisted of micronodules, nodules, and progressive massive fibrosis. The comparative analysis demonstrates the superiority of an optimal CT technique over chest radiography in the evaluation of simple silicosis, with improved sensitivity in the detection of small parenchymal opacities. CT provides additional information on the stage of the disease but also clarifies some ambiguities of the ILO classification of small opacities. CT was equivalent to radiography for complicated silicosis, except in the identification of necrosis. CT evaluations are complementary to plain radiography in the assessment of CWP, and the addition of high-resolution CT is useful in achieving a more accurate evaluation of the small parenchymal opacities

  1. The management of workers occupationally exposed to ionizing radiation

    International Nuclear Information System (INIS)

    In Canada, the regulation of radiation protection is a shared responsibility between the federal body (the Atomic Energy Control Board) and the appropriate provincial body (usually the Department of Health, or Department of Labour). The AECB is responsible, for example, for regulating the development, application and use of nuclear energy and radioisotopes, and the provinces are responsible for the regulation of all other forms of ionizing and non-ionizing radiations and for naturally-occurring radioactive material (NORM). Although there is consultation between the federal and provincial regulatory agencies, the division of jurisdictional authority has resulted in considerable differences in the approach towards implementation radiation protection programs in Canada. This is especially true in the management of workers occupationally exposed to ionizing radiation. These differences have produced unwarranted discrepancies in operating procedures and practices in the allocation of resources and manpower, and in the requirements governing radiological training, personnel monitoring and medical surveillance. In light of the General Amendments to the AEC Regulations, the 1990 Recommendations of the ICRP, and the IAEA recommendations on safety culture, the ACRP has considered it timely to undertake a study to examine the feasibility of establishing a more coherent approach to harmonize radiation protection practices within Canada. This study comprised an examination of the regulatory approach used in several countries: a review of the nature of radiation safety programs in various types of licensed institutions and facilities in Canada; and a review of recommendations of internationally-recognized authorities in radiation protection

  2. Evaluation of serum fibrosis markers in asbestos-exposed workers

    International Nuclear Information System (INIS)

    The usefulness of serum fibrosis markers to evaluate asbestos exposure was investigated. Subjects who underwent chest CT in screening for asbestos-exposed workers were divided in two groups, with or without pleural plaque findings, and they were compared in terms of serum fibrosis markers (Type IV collagen, Type III procollagen-N-peptide, Hyaluronic acid, KL-6, SP-D, SP-A). 8 younger cases, a case with elevated AST and a case with asbestosis of all the 43 cases who underwent chest CT were excluded. The remaining 33 cases were divided into on group of 17 cases with pleural plaque (plaque group) and the group of 16 cases without pleural plaque (normal group). Serum level of Type IV collagen in the plaque group was significantly higher than in the normal group (162±35 vs. 121±22, P<0.01), and the mean was higher than the cut-off value (≤140 ng/ml). This result suggests that higher serum level of type IV collagen predicts the presence of pleural plaque. Though chest X-ray is inferior to CT in the detection of pleural plaque, result can be expected to improve by additional evaluation of serum level of Type IV collagen. (author)

    2010-01-01

    Full Text Available Healthcare-associated infections are an important cause of morbidity and mortality among hospitalized patients worldwide. Transmission of health care associated pathogens generally occurs via the contaminated hands of health care workers. Hand hygiene has long been considered one of the most important infection control measures to prevent health care-associated infections. For generations, hand washing with soap and water has been considered a measure of personal hygiene. As early as 1822, a French pharmacist demonstrated that solutions containing chlorides of lime or soda could eradicate the foul odor associated with human corpses and that such solutions could be used as disinfectants and antiseptics. This paper provides a comprehensive review of data regarding hand washing and hand antisepsis in healthcare settings. In addition, it provides specific recommendations to uphold improved hand-hygiene practices and reduce transmission of pathogenic microorganisms to patients and personnel in healthcare settings. This article also makes recommendations and suggests the significance of hand health hygiene in infection control.

  6. Medical Inspection and Regrading of Workers Accidentally Exposed to Radiation

    International Nuclear Information System (INIS)

    Medical inspection and regrading of workers exposed to radiation at the time of an accident are basically variable according to the seriousness of the exposure. Minor cases only need a check-up at relatively lengthy intervals and regrading does not usually present any great problem. This paper deals with the particular case of whole-body irradiation involving very high exposure of a lower limb. Problems of medical supervision and regrading are still arising three years after the accident, without it being possible to determine or even foresee a consolidation period. The issues involved are legal, medical, social and psychological, and also relate to efficiency. The legal aspect of an accident of this kind involves a series of obligations, such as the prolonged inspection laid down in legal instruments, which varies, moreover, with the country. It also includes the jurisprudential aspect, in particular the much-debated distinction between an industrial accident and an occupational disease. The medical aspect of long-term supervision entails a fairly frequent check on the proper functioning of the different systems, with particular stress on blood sampling and genetic tests, including a chromosome examination. The social aspect is particularly important in the event of nuclear accidents. In the case under consideration the accident resulted in total incapacity to work for almost three years, followed by resumption of work on a part-time basis. The long period of isolation of the patient and the anxiety of his family and those around him regarding the possible outcome of the accident are aspects peculiar to serious exposure to radiation. The psychological aspect is furthermore a part of the social aspect. During his period of confinement the patient only comes into contact with a few persons, whereas once he has been discharged from hospital he is an object of curiosity and publicity that are at times excessive. Finally, regrading that does not involve downgrading

    In this article, we discuss a case study that deals with the care chain phenomenon and focuses on the question of how Poland and the Ukraine as sending countries and Poland as a receiving country are affected and deal with female migrant domestic workers. We look at the ways in which these women organize care replacement for their families left behind and at those families’ care strategies. As public discourse in both countries is reacting to the feminization of migration in a form that specifically questions the social citizenship obligations of these women, we also look at the media portrayal of the situation of nonmigrating children. Finally, we explore how different aspects of citizenship matter in transnational care work migration movements. PMID:22611571

  13. Artificial stone dust-induced functional and inflammatory abnormalities in exposed workers monitored quantitatively by biometrics

    2016-03-01

    Full Text Available The manufacture of kitchen and bath countertops in Israel is based mainly on artificial stone that contains 93% silica as natural quartz, and ∼3500 workers are involved in cutting and processing it. Artificial stone produces high concentrations of silica dust. Exposure to crystalline silica may cause silicosis, an irreversible lung disease. Our aim was to screen exposed workers by quantitative biometric monitoring of functional and inflammatory parameters. 68 exposed artificial stone workers were compared to 48 nonexposed individuals (controls. Exposed workers filled in questionnaires, and all participants underwent pulmonary function tests and induced sputum analyses. Silica was quantitated by a Niton XL3 X-ray fluorescence spectrometer. Pulmonary function test results of exposed workers were significantly lower and induced sputa showed significantly higher neutrophilic inflammation compared to controls; both processes were slowed down by the use of protective measures in the workplace. Particle size distribution in induced sputum samples of exposed workers was similar to that of artificial stone dust, which contained aluminium, zirconium and titanium in addition to silica. In conclusion, the quantitation of biometric parameters is useful for monitoring workers exposed to artificial stone in order to avoid deterioration over time.

    Full Text Available Objective: to evaluate the prevalence of these symptoms and their relationship with pesticide exposure and the cholinesterase levels in agricultural workers. Methodology: an analytical cross-sectional study conducted in Mexico. Cholinesterase concentration and symptom frequency were assessed for 106 agricultural workers. Exposure was defined with a composed index of 15 variables. Results: symptom prevalence was 52 out of 100 workers. 31% of workers had 1 to 3 of the symptoms, 16% had 4 to 9 of them and 5% had 10 or more of the symptoms. There was an association, p = 0.03, between days of exposure and persistent symptoms. Likewise, there was an association between exposure level and the presence of probable and specific symptoms. Patients with the highest exposure level had 20% more chances of exhibiting symptoms. Cholinesterase concentration ranges were normal. Anemia was detected in 28% of the population. It was three times as frequent in females as in males (p < 0.001. Conclusions: it was possible to identify the increase of persistent symptoms in workers with cholinesterase levels that are usually considered to be normal.

  3. Intracellular free calcium concentration and calcium transport in human erythrocytes of lead-exposed workers

    International Nuclear Information System (INIS)

    Erythrocytes are the route of lead distribution to organs and tissues. The effect of lead on calcium homeostasis in human erythrocytes and other excitable cells is not known. In the present work we studied the effect of lead intoxication on the uptake and efflux (measured as (Ca2+-Mg2+)-ATPase activity) of calcium were studied in erythrocytes obtained from lead-exposed workers. Blood samples were taken from 15 workers exposed to lead (blood lead concentration 74.4 ± 21.9 μg/dl) and 15 non-exposed workers (9.9 ± 2 μg/dl). In erythrocytes of lead-exposed workers, the intracellular free calcium was 79 ± 13 nM, a significantly higher concentration (ANOVA, P 2+-Mg2+)-ATPase activity. Lipid peroxidation was 1.7-fold higher in erythrocytes of lead-exposed workers as compared with control. The alteration on calcium equilibrium in erythrocytes is discussed in light of the toxicological effects in lead-exposed workers

    Full Text Available Abstract Background Significant numbers of people are exposed to tetrachloroethylene (perchloroethylene, PCE every year, including workers in the dry cleaning industry. Adverse health effects have been associated with PCE exposure. However, investigations of possible cumulative cytogenetic damage resulting from PCE exposure are lacking. Methods Eighteen dry cleaning workers and 18 laundry workers (unexposed controls provided a peripheral blood sample for cytogenetic analysis by whole chromosome painting. Pre-shift exhaled air on these same participants was collected and analyzed for PCE levels. The laundry workers were matched to the dry cleaners on race, age, and smoking status. The relationships between levels of cytological damage and exposures (including PCE levels in the shop and in workers' blood, packyears, cumulative alcohol consumption, and age were compared with correlation coefficients and t-tests. Multiple linear regressions considered blood PCE, packyears, alcohol, and age. Results There were no significant differences between the PCE-exposed dry cleaners and the laundry workers for chromosome translocation frequencies, but PCE levels were significantly correlated with percentage of cells with acentric fragments (R2 = 0.488, p Conclusions There does not appear to be a strong effect in these dry cleaning workers of PCE exposure on persistent chromosome damage as measured by translocations. However, the correlation between frequencies of acentric fragments and PCE exposure level suggests that recent exposures to PCE may induce transient genetic damage. More heavily exposed participants and a larger sample size will be needed to determine whether PCE exposure induces significant levels of persistent chromosome damage.

    Respiratory consequences of work in food processing industry were studied in 764 female workers exposed to organic dusts associated with the processing of green and roasted coffee, tea, spices, dried fruits, cocoa and flour. A group of 387 female workers not exposed to respiratory irritants served as controls for the prevalence of acute (during work shift) and chronic respiratory symptoms. A greater prevalence of all acute and chronic respiratory symptoms was consistently found among exposed workers than among control workers. The highest prevalence of chronic respiratory symptoms was recorded for chronic cough (40%), followed by acute symptoms of dry cough (58.7%). The difference in the prevalence of chronic respiratory symptoms between the exposed and control workers was in general significant (p DSCG) significantly diminished across-shift reductions for FEF50 and FEF25 in a subgroup of the examined workers. Our data suggested the female workers employed in food processing industry to be at risk of developing both acute and chronic respiratory symptoms as well as ventilatory capacity impairment as the result of occupational exposures.

    Kreiss, K; Wegman, D H; Niles, C A; Siroky, M B; Krane, R J; Feldman, R G

    Neurogenic bladder dysfunction, characterized by hesitancy, need to strain, decreased stream, and increased duration of urination, developed in 104 (63%) of 166 employees working in the manufacture of polyurethane foam. Highest rates of illness (69%) occurred in production workers, and no illness occurred in office or warehouse workers. Onset of the epidemic coincided with introduction of a catalyst, dimethylaminopropionitrile (DMAPN), and monthly case incidence rates increased as DMAPN use increased. Outbreak ceased abruptly when DMAPN use was stopped. Of eight patients who underwent neurourologic testing during recovery, seven lacked either detrusor reflex or normal sensation of bladder filling; seven had a subclinical sensory abnormality; three had prolonged sacral-evoked responses; and two of these three had limb motor neuropathies. Dimethylaminopropionitrile is unique among known neurotoxins in producing urinary symptoms more frequently than limb nerve symptoms. PMID:6243373

  9. Dose constraints to the individual annual doses of exposed workers in nuclear medicine laboratories

    International Nuclear Information System (INIS)

    The study deals with the analysis of dose distribution records of the occupationally exposed workers in the field of nuclear medicine in Greece and the establishment of constraints to their individual annual doses (IAD) within the process of optimization in radiation protection. The exposed workers were grouped according to their specialties (medical doctors, technicians, others), the kind of services provided (diagnosis or diagnosis plus I-131 therapy) and the sector they belonged (public or private). Dose constraints (DC) were set at the level below which the IAD of the 75% of the exposed workers per specialty were included. Our results showed that DC levels were exceeded by the 13% of the exposed workers in the public and the 30% in the private sector respectively. Further investigation indicated that the reasons leading to the exceeding of DCs, may be attributed to the workload of the exposed workers which is greater in the private than in the public sector as well as, to possible difference in the specific tasks of workers between the two sectors.

  11. Whole-body doses of occupationally exposed female workers in Nigeria (1999-2001)

    International Nuclear Information System (INIS)

    The work described in this note is based on the national dose registry of radiation workers in Nigeria kept by the Federal Radiation Protection Service. In each of the three years (1999-2001) used for this analysis, the number of male radiation workers was more than that of female radiation workers in both medicine and industry. The ratio of the number of female radiation workers to that of their male counterparts, however, is smaller in industry. The mean of the annual doses of all radiation workers increased from 3.6 mSv in 1999 to 4.7 mSv in 2000 and to 7.7 mSv in 2001. This increase was a result of the yearly increase in mean annual doses to radiation workers in industry. In the industrial category, the mean annual doses of female radiation workers were higher than those of their male counterparts in 1999 and 2001 in both occupation categories. In 2000, while the mean annual doses were the same for both male and female radiation workers in the medical category, the mean annual dose of male radiation workers was higher than that of female radiation workers in industry. Female radiation workers received the highest annual doses in 1999 and 2001. These results indicate the need for the regulatory authority to pay more careful attention to the control of female radiation workers' exposures. (note)

    Community health workers are increasingly recognized as useful for improving health care and health outcomes for a variety of chronic conditions. Community health workers can provide social support, navigation of health systems and resources, and lay counseling. Social and cultural alignment of community health workers with the population they serve is an important aspect of community health worker intervention. Although community health worker interventions have been shown to improve patient-centered outcomes in underserved communities, these interventions have not been evaluated with sickle cell disease. Evidence from other disease areas suggests that community health worker intervention also would be effective for these patients. Sickle cell disease is complex, with a range of barriers to multifaceted care needs at the individual, family/friend, clinical organization, and community levels. Care delivery is complicated by disparities in health care: access, delivery, services, and cultural mismatches between providers and families. Current practices inadequately address or provide incomplete control of symptoms, especially pain, resulting in decreased quality of life and high medical expense. The authors propose that care and care outcomes for people with sickle cell disease could be improved through community health worker case management, social support, and health system navigation. This paper outlines implementation strategies in current use to test community health workers for sickle cell disease management in a variety of settings. National medical and advocacy efforts to develop the community health workforce for sickle cell disease management may enhance the progress and development of "best practices" for this area of community-based care.

    Full Text Available Abstract Background Violence at work is one of the major concerns in health care activities. The aim of this study was to identify the prevalence of physical and non-physical violence in a general health care facility in Italy and to assess the relationship between violence and psychosocial factors, thereby providing a basis for appropriate intervention. Methods All health care workers from a public health care facility were invited to complete a questionnaire containing questions on workplace violence. Three questionnaire-based cross-sectional surveys were conducted. The response rate was 75 % in 2005, 71 % in 2007, and 94 % in 2009. The 2009 questionnaire contained the VIF (Violent Incident Form for reporting violent incidents, the DCS (demand/control/support model for job strain, the Colquitt 20 item questionnaire for perceived organizational justice, and the GHQ-12 General Health Questionnaire for the assessment of mental health. Results One out of ten workers reported physical assault, and one out of three exposure to non-physical violence in the workplace in the previous year. Nurses and physicians were the most exposed occupational categories, whereas the psychiatric and emergency departments were the services at greatest risk of violence. Workers exposed to non-physical violence were subject to high job strain, low support, low perceived organizational justice, and high psychological distress. Conclusion Our study shows that health care workers in an Italian local health care facility are exposed to violence. Workplace violence was associated with high demand and psychological disorders, while job control, social support and organizational justice were protective factors.

    The object of this work is to introduce the training program in Radiation Protection implemented in our Hospital, and its evaluation and follow-up. Material AND Methods: The training program in Radiation Protection implanted by the Department of Radiation Protection in the Hospital de la Ribera consists of three types of training modalities: Annual Seminars: applicable to all the exposed workers and divided in a general part and a specific one for each area; Informative lectures: applicable to a specific department, deal with specific issues of interest without predetermined frequency; Individualised training: applicable to pregnant, new workers, job moves and duties change. The follow-up of the program is carried out by mean of inquiries about general and site-specific knowledge on radiation protection. Results The results of the inquiries are analysed and related with the continuous training program. Conclusion: It is remarkable that departments with workers without academic training in radiation protection (Intensive Care Unit, Surgery, Endoscopy,) need a more dedicated training. The results confirm the validity of the three training modalities: The annual seminar provides a continuous training to all exposed workers; the informative lecture is useful to handle immediately issues of current interest in a specific department and the individual training are useful to acquire specific knowledge about radiation risks and radiation protection rules in new working situations.

    Full Text Available Background and Design: We aimed to determine the frequency of latex allergy in our hospital and to to evaluate the clinical and demographical features of the cases.Materials and Methods: A detailed questionnaire was administered to healthcare workers by a physician. Skin prick test with latex and patch test with rubber chemicals and a piece of latex glove were performed for all healthcare workers. Latex-specific IgE was measured in serum.Results: The study sample consisted of 36 nurses, 14 doctors, and 50 healthcare workers. While 46 subjects had symptoms, 54 subjects had no symptoms. The relationship of clinical disease with working duration, exposure duration (hour/day, history of atopy, and drug/food allergies was statistically significant. Five nurses and 1 healthcare worker had positive skin prick test. Two of them had positive latex-specific IgE. Positive skin prick test statistically significantly correlated with occupation, working duration, exposure duration (hour/day and positive latex-specific IgE. Two nurses and 2 healthcare workers had positive latex-specific IgE. Two of them had positive skin prick test. Positive latexspecific IgE statistically significantly correlated with working duration, exposure duration, and positive skin prick test. Patch test with a piece of latex glove was negative in all subjects. Three healthcare workers had positive patch test with thiuram-mix, one of them had also positive patch test with mercaptobenzothiazole.Discussion: One of the risk factors for latex allergy is occupations involving frequent exposure to latex products. Latex allergy should be taken into consideration if type I hypersensitivity reactions occur in occupational groups at risk for anaphylactic reaction.

    In the present study the cytogenetic effects in hospital workers exposed to low-level radiation were evaluated. Samples of peripheral blood were collected from 63 subjects working in radiodiagnostics and from 30 subjects, working in the same hospitals, who were used as controls. A higher number of cells with chromosome-type aberrations (CA) was observed in the exposed workers vs. the controls and the difference was statistically significant (p<0.05). No correlation was, on the contrary, found between CA and years of exposure. A significant difference was observed in the incidence of cells with CA between smokers and non-smokers, but in the control group only. In contrast, in the workers exposed to ionizing radiation, the frequency of cells with CA was very similar in smokers and non-smokers. 13 refs.; 4 tabs

  7. Influence of Some Pesticides on Humoral and Cellular Immunity of Exposed Workers in Pesticides Industries

    International Nuclear Information System (INIS)

    Pesticide poisoning is a major public health problem in developing countries. In most of these countries organophosphate pesticides constitute the most widely used pesticides. The main toxicity of OPs is neurotoxicity, which is caused by the inhibition of acetylcholinesterase. OPs also affect the immune response, including effects on cellular and humoral immunity. Our study examined the effect of organophosphorus compounds on humoral and cellular immunity of exposed workers in pesticides industries. The study was conducted into 40 subjects. They were 2 groups; 20 exposed workers from Gharbeia and Kafr Elsheikh at 2008 and 2009 and 20 unexposed individuals as a control group at the same period of time. We examined some immune parameters; pseudocholinesterase, WBCs count, CD4%, CD8%, CD4/CD8, CD56%, Interleukin 2, IgG and IgM. Also we take history and clinical examination for them. We reported a highly significant decrease in pseudo cholinesterase level among the exposed group in comparison to the control group, highly significant increase in percentage of CD8 in the exposed group in comparison to control group, highly significant decrease in CD4 / CD8 ratio in the exposed group in comparison to control group, highly significant decrease in percentage of CD56 in the exposed group in comparison to control group and a highly significant increase in IgG level in the exposed group in comparison to control group. On the other hand, we reported no significant change in white blood cells count between the exposed and control groups, no significant change in percentage of CD4 among the exposed and control group, no significant change in Interleukin 2 level among the exposed and control group and no significant change in IgM level among the exposed and control group. We concluded that pesticides extensively affect the humoral and cellular immune system of occupationally exposed workers.

    The aim of this study is to evaluate whether occupational exposure to urban stressors could cause alterations of systolic and diastolic blood pressure in "outdoor" workers. The research was conducted on a sample of 101 municipal policemen. The sample was divided in 2 groups according to length of service: group A (length of service between 1 and 15 years) and group B (length of service > 15 years). Group A and Group B were matched for age, overall length of service, cigarette smoking habit and consumption of alcohol and spirits. Group A was then divided into: Al (length of service between 1 and 7 years) and A2 (length of service between 7 and 15 years). The mean values of systolic and diastolic blood pressure at rest showed statistically significant differences with increased values in group B compared to both groups Al (p<0.05) and A2 (p<0.05). The study suggests that occupational exposure to urban stressors affects the blood pressure regulating system enhancing the risk of blood hypertension. PMID:26193737

    2016-06-01

    Today's employers are hiring a more age-diverse workforce. As Americans work longer, age-related changes often create activity limitations. Musculoskeletal disorders affect many older workers heightening their risk of workplace injury. Compounded by multiple comorbidities, older workers will need occupational health nurses with expert knowledge to maintain safe and productive workplaces. Older workers do not experience as many injuries as younger workers, but when they are injured, recovery is longer. The author developed and conducted a survey of New Jersey occupational health nurses. The results showed that overexertion injuries are the most frequently treated injuries in employee health offices. For occupational health nurses to keep employees safe, best practices must be delineated; this musculoskeletal safety guideline provides recommendations for evidence-based care of older workers.

METHOD: this cross-sectional study involved 62 HIV+ mothers whose children of up to one year old had been exposed to the virus at birth. The Assessment Scale of Care Skills for Children Exposed to HIV at Birth consists of 52 items and five dimensions, indicating high, moderate or low care ability. RESULTS: 72.7% of the mothers appropriately offered zidovudine syrup; 86.0% were highly skilled to prepare and administer milk formula; 44.4% were moderately able to prepare and administer complementary feeding; 76.5% revealed high ability to administer prophylactic treatment against pneumonia and 95.3% demonstrated high abilities for clinical monitoring and immunization. Significant associations were found between some maternal variables and the scale dimensions. CONCLUSION: the scale permits the assessment of maternal care delivery to these children and the accomplishment of specific child health interventions.

    Polycyclic aromatic hydrocarbons (PAHs) result from the incomplete combustion of natural or synthetic organic materials. The working environment at a coke plant can negatively affect the employed workers who were exposed to coke oven emissions containing PAHs, which formed and released into the environment by the process of pyrolysis of coke. This study aims to analyze the relationship between the exposure of PAHs and the risk of genetic damages such as chromosomal alteration (CA), micronucleus (MN), and DNA damage (PCR-RFLP) in peripheral blood lymphocytes of 27 coke oven workers and equal number of control subjects. The exposed subjects and controls were divided into two groups based on their age (group Icoke oven workers under risk should be monitored for adverse effects of the any long-term exposure.

    The study is an attempt, within the process of the optimization of radiation protection, to propose constraints to the individual annual doses of classified workers employed in the medical sector of ionizing radiation applications in Greece. These exposed workers were grouped according to their specialties, i.e. medical doctors, technicians and nurses and their occupational category with common or similar tasks, such as diagnostic radiology, interventional radiology, nuclear medicine and radiotherapy. The last 5 years' annual dose distributions of these occupational groups, coming from the National Dose Registry Information System (NDRIS) of the Greek Atomic Energy Commission (GAEC) were analyzed. The proposed dose constraints (DCs) were set at levels, below which the annual doses of the 70 or 75% of the exposed workers per category are expected to be included. At the present stage the derived values may be considered achievable ceiling values referring to acceptably applied practices rather than to optimized ones, taking into account social and economic criteria.

    Gallagher, J

    2012-02-03

    Varicella zoster virus (VZV) is an occupational hazard for a percentage of health care staff. Nine hundred and seventy staff members attending the Occupational Health Department at Cork University Hospital took part in the survey. A latex agglutination assay was used to determine the health care workers immune status to VZV. Of the 970 workers tested, 928 (95.7%) were immune to VZV. The sensitivity, specificity and predictive value of an enquiry regarding a history of chicken-pox was determined on a sample of 206 health care workers. The positive predictive value was 95% (119\\/125) and the negative predictive value was 11% (4\\/35). The sensitivity of the enquiry was 79% (119\\/150), the specificity was 40% (4\\/10), reducing to 61% (119\\/195) and 36% (4\\/11) respectively when individuals with uncertain histories were included in the calculations. The advantages and disadvantages of selective staff screening are discussed. In the authors\\' opinion all health care workers involved in the clinical care of patients should be screened by serology for past VZV infection before taking up duty and those who are susceptible to VZV should be made aware of the risks and health effects associated with VZV if contracted.

  20. Why Do Care Workers Withdraw From Elderly Care? Researcher’s Language as a Hermeneutical Key

    2012-11-01

    Full Text Available Care workers frequently withdraw from elderly people in their care; this has resulted in a number of scandals in the media. Here I analyze an empirical scene observed at an old people’s home in Denmark, which contains behavioral patterns among the care workers which could be seen as withdrawal. At the same time it illustrates the care workers’ commitment to the elderly. A paradoxical “empathy at a distance” is characteristic of the scene. When analyzing my written observations in an interpretation group, my use of language was a point of discussion. What did it mean when I described the interactions between care workers and elderly residents in words commonly used to describe mother-child interactions? My use of language became a “hermeneutical key” which enabled a psychoanalytically inspired interpretation. This focuses on the care relationship as activating our earliest memories of our own care relations, independently of whether we are in the role of care providers or care receivers. Through collusion theory, the interpretation accepts both the anxiety which the helpless elderly people arouse in the care workers and their motivation for care work as two sides of a subjectively important theme. The article illustrates how working consciously with the researcher’s subjectivity makes it possible to understand apparently irrational patterns. The insights thus gained may be used to prevent withdrawals in care work as an argument for care workers’ need for emotional supervision.

  2. Medical surveillance of workers exposed to radiation between 2005 and 2009

    International Nuclear Information System (INIS)

    This paper looks into occupational exposure to ionising radiation and causes of work disability in workers between 2005 and 2009. In that period, about 6000 workers were occupationally exposed to radiation. Of 26,508 examinations performed, the Croatian Institute for Health Protection and Safety at Work received data for 13,162. Sixty workers were found permanently disabled and the main cause was lens opacity followed by leucopenia. Eleven workers were diagnosed occupational disease, including three breast cancers, two leukaemias, one colon cancer, one lung cancer, one malignant tumour of blood-forming organs, and one thrombocytopenia. In addition, two diagnosed cataracts were typical of radiation. These findings urge for the use of eye protection at work. (authors)

  3. Study of External Radiation Expose Dose on Hands of Nuclear Medicine Workers

    International Nuclear Information System (INIS)

    The aims of this study are to assess external radiation exposed doses of body and hands of nuclear medicine workers who handle radiation sources, and to measure radiation exposed doses of the hands induced by a whole body bone scan with high frequency and handling a radioactive sources like 99mTc-HDP and 18F-FDG in the PET/CT examination. Skillful workers, who directly dispense and inject from radiation sources, were asked to wear a TLD on the chest and ring finger. Then, radiation exposed dose and duration exposed from daily radiation sources for each section were measured by using a pocket dosimeter for the accumulated external doses and the absorbed dose to the hands. In the survey of four medical institutions in Incheon Metropolitan City, only one of four institutions has a radiation dosimeter for local area like hands. Most of institutions uses radiation shielding devices for the purpose of protecting the body trunk, not local area. Even some institutions were revealed not to use such a shielding device. The exposed doses on the hands of nuclear medicine workers who directly handles radioactive sources were approximately twice as much as those on the body. The radiation exposure level for each section of the whole body bone scan with high frequency and that of the PET/CT examination showed that radiation doses were revealed in decreasing order of synthesis of radioactive medicine and installation to a dispensing container, dispensing, administering and transferring. Furthermore, there were statistically significant differences of radiation exposure doses of the hands before and after wearing a syringe shielder in administration of a radioactive sources. In this study, although it did not reach the permissible effective dose for nuclear medicine, the occupational workers were exposed by relatively higher dose level than the non-occupational workers. Therefore, the workers, who closely exposed to radioactive sources should be in compliance with safety management

  4. Inventory of MRI applications and workers exposed to MRI-related electromagnetic fields in the Netherlands

    International Nuclear Information System (INIS)

    Objective: This study aims to characterise and quantify the population that is occupationally exposed to electromagnetic fields (EMF) from magnetic resonance imaging (MRI) devices and to identify factors that determine the probability and type of exposure. Materials and methods: A questionnaire survey was used to collect information about scanners, procedures, historical developments and employees working with or near MRI scanners in clinical and research MRI departments in the Netherlands. Results: Data were obtained from 145 MRI departments. A rapid increase in the use of MRI and field strength of the scanners was observed and quantified. The strongest magnets were employed by academic hospitals and research departments. Approximately 7000 individuals were reported to be working inside an MRI scanner room and were thus considered to have high probability of occupational exposure to static magnetic fields (SMF). Fifty-four per cent was exposed to SMF at least one day per month. The largest occupationally exposed group were radiographers (n ∼ 1700). Nine per cent of the 7000 involved workers were regularly present inside a scanner room during image acquisition, when exposure to additional types of EMF is considered a possibility. This practice was most prevalent among workers involved in scanning animals. Conclusion: The data illustrate recent trends and historical developments in magnetic resonance imaging and provide an extensive characterisation of the occupationally exposed population. A considerable number of workers are potentially exposed to MRI-related EMF. Type and frequency of potential exposure depend on the job performed, as well as the type of workplace

  5. Dose estimation by ESR on tooth enamel from two workers exposed to radiation due to the JCO accident

    International Nuclear Information System (INIS)

    Electron spin resonance (ESR) dosimetry is useful to estimate the external dose for the general population as well as for occupational workers in a nuclear emergency. Three teeth were extracted from two exposed workers (A and B) related to the JCO criticality accident. Tooth enamel was carefully separated from other tooth parts and subjected to ESR dosimetry. Doses equivalent to the γ-ray dose of 60Co were estimated as follows: for worker A, the buccal and lingual sides of the eighth tooth in the upper right side, 11.8±3.6 and 12.0±3.6 Gy, respectively; for worker B, the buccal and lingual sides of the fourth tooth in the upper right side and the fifth tooth in the upper left side, 11.3±3.4 and 10.8±3.3 Gy, 11.7±3.5 and 11.4±3.4 Gy, respectively. The estimated doses were found to be similar and not dependent on the tooth positions, whether the buccal or lingual sides in each tooth. (author)

    The intake of radioactive material by workers can occur in the radiopharmaceuticals production, during the handling of these in the medical fields (nuclear medicine) and in biological and research laboratories. The workers who work in areas where exposures are significant are routinely monitored to demonstrate that the workers are receiving adequate protection from internal contamination. Direct measurements of whole-body and thyroid contents provide an estimate of the activity of these radionuclides in the potentially exposed workers. The whole-body measurements of the workers, trainees and visitors are routinely performed by the In Vivo Monitoring Laboratory (LMIV) of the Energy and Nuclear Research Institute (IPEN/CNEN-SP). The frequency of measurements is defined by the Radioprotection Service (SRP) and the Dose Calculation Group of IPEN. For this purpose LMIV has two counters, whole body.

    Full Text Available Taking care of oneself is crucial for maintaining one´s psychical and physical health. In the context of risky profession this topic can play an even more important role, because it can be the source of necessary information for improvement of coping capacity when one is confronted with crisis situations. The aim of the present study is to identify the most common forms of self-care among selected risky professions. In the second part is the attention focused on the comparison of the specificities of risky to non-risky professions in self-care. Methods: For data collection Self-regulation Self-care Questionnaire by authors Hricová and Lovaš (in press is used. The sample consists of two groups. In the first one participated 156 respondents, who worked in risky professions - namely police officers (60 at the age between 22 to 55 years (average age is 36.88, SD=9.49, fire fighters (46 at the age between 22 to 62 years (average age is 35.13, SD=8.31 and paramedics (50 at the age between 25 to 55 years (average age is 40.3, SD=6.62. 76.2% of the sample are men, 19.0% are women and 4,8% didn´t state their gender. The second sample consists of 161 participants who work in administrative, industry production or IT sphere. They were at the age between 23 to 61 years (average age is 38.01, SD=10.45. 74% of the sample are men and 21.7% are women. Results and discussion: Results confirmed the dominance of psychological self-care above physical among risky professions. To the forefront gets the need to live meaningful life, to fully use one´s skills and to be satisfied with one´s life and decisions. All this needs can be assigned to the necessity of sense, which could be seen as a result of everyday contact with critical and life threaten situations. Equally important sphere of self-care is the necessity of high-quality relationships, which doesn´t mean only relationships with family or friends. It is important to highlight also relationships with

  13. Mortality and causes of death among workers exposed to phosgene in 1943-45

    International Nuclear Information System (INIS)

    Mortality and causes of death from death certificates were analyzed among workers exposed to phosgene while working at a uranium-processing plant in Tennessee in 1943-45. Standardized mortality ratios (SMRs) were calculated by using death rates for U.S. white males. As of 1979, SMRs for all causes and for various selected causes were similar in 694 male chemical workers chronically exposed to low levels of phosgene in 1943-45 and in 9280 male controls who worked at the same plant. SMRs for diseases of the respiratory system were 107 (14 observed vs. 13.07 expected) in the chemical workers and 119 (292 observed vs. 245.75 expected) in the controls. In a group of 106 males who were acutely exposed to high levels of phosgene, there were 41 deaths observed vs. 33.87 expected (SMR = 121; 95% confidence limits = 86 and 165). One death, occurring within 24 hours of exposure, was from pulmonary edema due to phosgene poisoning (coded to accidental causes). Five deaths were coded to diseases of the respiratory system (SMR = 266; 95% CL = 86 and 622); in 2 of these 5 deaths, bronchitis due to phosgene exposure had been reported in 1945. Among 91 female workers with acute high-level phosgene exposure, frequencies of symptoms and early health effects (pneumonitis and bronchitis) differed from those reported for the 106 male cases; preliminary data on vital status of these females are too incomplete for analysis, and further follow-up is needed

    1994-01-01

    Home care services make it possible for millions of older Americans to continue living in the community. Such services may enhance the recipients' quality of life while providing essential respite to family caregivers. But while there has been increasing recognition of the burden borne by the predominantly female family caregivers, there has been less attention to the plight of the home care workforce. With the growth of the home care industry, the burden of care has to some extent shifted from one category of female caregivers to another. This paper, based on a survey of 16 agencies and 1,900 workers, examines the employment conditions of home care workers in Washington state. The study reveals a pattern of harsh working conditions, low wages, and few benefits. The findings raise questions about the ethics and efficacy of government policies that are based on the exploitation of home care workers. PMID:10134029

  16. Paraoxonase-1 genetic polymorphisms and susceptibility to DNA damage in workers occupationally exposed to organophosphate pesticides

    International Nuclear Information System (INIS)

    Human paraoxonase 1 (PON1) is a lipoprotein-associated enzyme involved in the detoxification of organophosphate pesticides (OPs) by hydrolyzing the bioactive oxons. Polymorphisms of the PON1 gene are responsible for variation in the expression and catalytic activity of PON1 enzyme. In the present study, we have determined (a) the prevalence of two common PON1 polymorphisms, (b) the activity of PON1 and acetylcholinesterase enzymes, and (c) the influence of PON1 genotypes and phenotypes variation on DNA damage in workers exposed to OPs. We examined 230 subjects including 115 workers exposed to OPs and an equal number of normal healthy controls. The results revealed that PON1 activity toward paraoxon (179.19 ± 39.36 vs. 241.52 ± 42.32 nmol/min/ml in controls) and phenylacetate (112.74 ± 17.37 vs. 134.28 ± 25.49 μmol/min/ml in controls) was significantly lower in workers than in control subjects (p 192QR (Gln/Arg) and PON155LM (Leu/Met) in workers and control subjects (p > 0.05). The PON1 activity toward paraoxonase was found to be significantly higher in the R/R (Arg/Arg) genotypes than Q/R (Gln/Arg) and lowest in Q/Q (Gln/Gln) genotypes in both workers and control subjects (p 55LM (Leu/Met), PON1 activity toward paraoxonase was observed to be higher in individuals with L/L (Leu/Leu) genotypes and lowest in individuals with M/M (Met/Met) genotypes in both groups (p < 0.001). No influence of PON1 genotypes and phenotypes was seen on the activity of acetylcholinesterase and arylesterase. The DNA damage was observed to be significantly higher in workers than in control subjects (p < 0.05). Further, the individuals who showed least paraoxonase activity i.e., those with (Q/Q [Gln/Gln] and M/M [Met/Met]) genotypes showed significantly higher DNA damage compared to other isoforms in workers exposed to OPs (p < 0.05). The results indicate that the individuals with PON1 Q/Q and M/M genotypes are more susceptible toward genotoxicity. In conclusion, the study suggests wide

  18. Severe hypersensitivity reaction to injectable Gallimum 67 in a worker exposed to silica

    International Nuclear Information System (INIS)

    Gallium 67 scintigraphy is employed in the evaluation of workers with possible pneumoconiosis. To our knowledge, however, a severe hypersensitivity reaction following the intravenous injection of Gallium 67 has not been described. We report the case of a worker chronically exposed to silica who developed an allergic cutaneous and severe articular reaction following the injection of Gallium 67 while being investigated for possible silicosis. Hilar adenopathy was noted on the chest roentgenogram and, retrospectively, circulating immune complexes were found in the patient's serum. The presence of a positive prick skin test to benzyl alcohol suggests that this preservative caused the hypersensitivity reaction. (au)

    2005-01-01

    Full Text Available Introduction: Smoking is one of the main risk factors in various diseases of different systems of the body, including the respiratory system and asbestosis is pulmonary fibrosis due to asbestos inhalation. Aim: This investigation evaluates the effects of smoking on the respiratory function and aggravation of respiratory complications in asbestos workers. This study was performed in August, 2002 at The Haajat Chrysotile Asbestos factory of Nehbandan, Birjand, Khorasan, Iran. Methods: A cross –sectional study was done on 56 Asbestos mine workers, randomly chosen and matched in two groups; smokers (25 individuals & nonsmokers (31 individuals. Asbestos levels were measured in different areas of the factory and mine. All of the workers were interviewed and underwent clinical examination and spirometery. Results: The mean value of asbestos in the respiratory field of the exposed workers was approximately 80 times over the standard limit (39.75 f/ml; TLV= 0.5 f/ml. According to clinical examination, both groups showed some kind of respiratory dysfunction, but cough & bloody sputum in the smoker group was significant. So, pulmonary function test impairment was seen in both the groups, but obstructive and mixed patterns were significant in the smoker group (P<0.01. Conclusion: The results demonstrate that cigarette smoking results in a significant increase and aggravation of pulmonary complications in asbestos workers. These changes are prominent even in those workers smoking less than 5 p/y. We therefore suggest that smoking and asbestos inhalation aggravate each others complications because smoking, even in low amounts causes respiratory problems in these workers and asbestosis presents itself in smokers much earlier than expected. . In view of the wide use of asbestos in friction industries like manufacture of brakes of vehicles, smoking can produce undesirable effects in those exposed for longer periods to heavy traffic, such as traffic police

    Full Text Available Objectives: To evaluate sensitization to chemicals present in work environment after an outbreak of contact dermatitis in workers of vehicle equipment factory, exposed to polyurethane foam, based on 4,4'-diphenylmethane diisocyanate (MDI. Material and Methods: From among 300 employees, 21 individuals reporting work-related skin and/or respiratory tract symptoms underwent clinical examination, patch testing, skin prick tests, spirometry and MDI sIgE measurement in serum. Patch tests included isocyanates series, selected rubber additives, metals, fragrances, preservatives, and an antiadhesive agent. Results: Clinical examination revealed current eczema in the area of hands and/or forearms in 10 workers. Positive patch test reactions were found in 10 individuals, the most frequent to diaminodiphenylmethane and 4-phenylenediamine (7 persons. Reactions to an antiadhesive agent were assessed as irritant (5 workers. Except for sensitization to common aeroallergens, no significant abnormalities were found in the remaining tests. Occupational allergic contact dermatitis was diagnosed in 7 workers, irritant contact dermatitis in 10 and coexisiting allergic and irritant contact dermatitis in 3 workers. Conclusions: In workers manufacturing products from polyurethane foam, attention should be paid to the risk of developing contact dermatitis. Skin problems in our study group were attributable probably to insufficient protection of the skin.

    Full Text Available Abstract Background There is increasing evidence that reproductive abnormalities are increasing in frequency in both human population and among wild fauna. This increase is probably related to exposure to toxic contaminants in the environment. The use of sentinel species to raise alarms relating to human reproductive health has been strongly recommended. However, no simultaneous studies at the same site have been carried out in recent decades to evaluate the utility of wild animals for monitoring human reproductive disorders. We carried out a joint study in Guadeloupe assessing the reproductive function of workers exposed to pesticides in banana plantations and of male wild rats living in these plantations. Methods A cross-sectional study was performed to assess semen quality and reproductive hormones in banana workers and in men working in non-agricultural sectors. These reproductive parameters were also assessed in wild rats captured in the plantations and were compared with those in rats from areas not directly polluted by humans. Results No significant difference in sperm characteristics and/or hormones was found between workers exposed and not exposed to pesticide. By contrast, rats captured in the banana plantations had lower testosterone levels and gonadosomatic indices than control rats. Conclusion Wild rats seem to be more sensitive than humans to the effects of pesticide exposure on reproductive health. We conclude that the concept of sentinel species must be carefully validated as the actual nature of exposure may varies between human and wild species as well as the vulnerable time period of exposure and various ecological factors.

  5. Haematological evaluation in workers exposed to ionizing radiation from a radiotherapy service

    International Nuclear Information System (INIS)

    Evaluation of haematological indicators is carried out as routing in medical surveillance of workers exposed to ionizing radiation, in order to assest the initial and continuing fitness for their intended tasks. The purpose of this work is to analize the behaviour of haematological parametsrs in relation with the time of exposure as well as received doses for workers. It was stabilished a 8 years follw up for the 74 workers of the radiotherapy service in the Oncological Hospital in Havana City. As result were observed no significant changes on mean number of leucocytes, platelets an haemoglobin, which oscillate within normal limits stablished for adult people. Allthought it was incountered an increase in the number of cases with leucopenia, in direct relation with the increase of time of exposure an cumulative doses. The incidence of those cases was 2,3 times higher in the 8th year of the follow up, in relation with the begining of the exposition to ionizing radiation

    The objective of this report is to analyze the possibility to establish a scheme to compensate damage to workers health exposed to ionizing radiation in Argentina for those cases in which it is possible to assume that the exposure to ionizing radiation is the cause of the cancer suffered by the worker. The proposed scheme is based on the recommendations set out in the 'International Conference on Occupational Radiation Protection: Protecting Workers against Exposure to Ionization Radiation, held in Geneva, Switzerland, August 26-30, 2002. To this end, the study analyzes the present state of scientific knowledge on cancer causation due to genotoxic factors, and the accepted form of the doses-response curve, for the human beings exposure to ionization radiation at low doses with low doses rates. Finally, the labor laws and regulations related to damage compensation; in particular the present Argentine Labor Law; the National Russian Federal Occupational Radiological Health Impairment and Workmen Compensation, t...

  7. A retrospective mortality study of workers exposed to radon in a Brazilian coal mine

    International Nuclear Information System (INIS)

    High levels of radon concentration were found in the underground workplace of an underground coal mine in Parana state, which has been in activity since 1942. Many of these workers were exposed for a long period of time to a work atmosphere with high radon, and radon decay products concentration. Taking this into account, it was decided to carry on a historical cohort, study with the workers' of this mining universe (underground and surface) in. order to evaluate the possible health effects related to this exposure, by means of a retrospective study of mortality. Through multiple strategies, it was possible to trace the vital status of 90% of the cohort. The causes of the deaths were identified by active search, of Death Declarations in the Health Office of Parana state and also in and other states. The success rate of cause of death identification was 100%. The final, cohort included 1946 underground workers and 910 surface workers. Standard mortality ratio (SMR) analysis showed lower mortality from all causes for both underground (SMR-88, 95%CI=78-98) and surface workers (SMR=96, 95%CI=81- 113). A highly significant SMR was observed for pneumonia cause of death among surface ((SMR=284, 95%CI=118-684) and underground miners (SMR-254, 95%CI=140-459), while a highly significant lung cancer mortality risk was observed only for underground miners (SMR=177, 95%CI=105-299) with a significant trend in relation to years of underground work (duration of exposure). Taking into account that mortality from smoking-related cancers other than lung cancer is not elevated in underground workers and diesel equipment were not used at this mine, the results suggest that the exposure to radon daughters may have been responsible for the lung cancer excess among underground workers. This work consists of the first historical Brazilian cohort involving miners exposed to radon and one of the few historical cohorts built in Brazil. It should be considered the fact that many workers of

    Exposure to diisocyanates was assessed by biological monitoring among workers exposed to the thermal degradation products of polyurethanes (PURs) in five PUR-processing environments. The processes included grinding and welding in car repair shops, milling and turning of PUR-coated metal cylinders, injection moulding of thermoplastic PUR, welding and cutting of PUR-insulated district heating pipes during installation and joint welding, and heat-flexing of PUR floor covering. Isocyanate-derived amines in acid-hydrolysed urine samples were analysed as perfluoroacylated derivatives by gas chromatography mass spectrometry in negative chemical ionisation mode. The limits of quantification (LOQs) for the aromatic diamines 2,4- and 2,6-toluenediamine (2,4- and 2,6-TDA) and 4,4'-methylenedianiline (4,4'-MDA) were 0.25 nmol l(-1), 0.25 nmol l(-1) and 0.15 nmol l(-1), respectively. The LOQ for the aliphatic diamines hexamethylenediamine (HDA), isophoronediamine (IpDA) and 4,4'-diaminodicyclohexyl methane (4,4'-DDHM) was 5 nmol l(-1). TDA and MDA were detected in urine samples from workers in car repair shops and MDA in samples from workers welding district heating pipes. The 2,4-TDA isomer accounted for about 80% of the total TDA detected. No 2.6-TDA was found in the urine of non-exposed workers. The highest measured urinary TDA and MDA concentrations were 0.79 nmol mmol(-1) creatinine and 3.1 nmol mmol(-1) creatinine, respectively. The concentrations found among non-exposed workers were 0.08 nmol mmol(-1) creatinine for TDA and 0.05 nmol mmol(-1) creatinine for MDA (arithmetic means). Exposure to diisocyanates originating from the thermal degradation of PURs are often intermittent and of short duration. Nevertheless, exposure to aromatic diisocyanates can be identified by monitoring diisocyanate-derived amines in acid-hydrolysed urine samples. PMID:12400919

    Motor conduction velocity (MCV) was measured in the median, ulnar, and peroneal nerves of 52 referents and 95 workers from a shoe factory, in a search for dose-effect and dose-response relationships between exposure to organic solvents and subclinical impairment of the peripheral nervous system (PNS). According to the environmental concentrations, the exposure was expressed as the sum of the products between the median hygienic effect (ranging from 0.08 to 2.89) and worktime (from 1 to 29 a) in every job. The motor action potential (MAP) amplitudes, durations and shapes of the exposed workers were significantly affected even if to a different extent and significance level when compared to those of the MCVs of the referents. The MCVs of the median (t . 3.17, p less than 0.01) and peroneal (t . 2.11, p less than 0.05) nerves were reduced as compared to reference values. In the exposed group, the MCV of the median nerve was negatively correlated with exposure score (r . 0.45, p less than 0.01) but not with age. No relationship was found between MVCs of the ulnar and peroneal nerves and exposure. The MCV of the median nerve was particularly slow in a subgroup of workers with an exposure score of greater than 20 (t . 2.30, p less than 0.05 vs the other exposed workers; t . 5.56, p less than 0.01 vs the referents). This exposure score represents only 50% of the maximum allowable score for a worktime of 40 a. Even if none of the examined workers showed clinical signs of polyneuropathy, evidence of subclinical effects on the PNS were found among subjects with long-term exposure to hexacarbon mixtures. Therefore, our results suggest the need for a lowering of current threshold limit values at least for n-hexane.

    Full Text Available Objectives: The aim of this study has been to investigate serum activities of liver enzymes in workers exposed to sub-TLV levels of dimethylformamide (DMF. Material and Methods: Seventy-two workers and 72 healthy controls participated in the study. All subjects underwent complete physical examinations and abdominal ultrasound examination. Serum aspartate aminotransferase (AST, alanine aminotransferase (ALT, and c-glutamyl transpeptidase (c-GT were determined by an auto-chemistry analyzer. The data of airborne concentrations of DMF was obtained from the local Center of Disease Control and Prevention. The level of urine N-acetyl-S-(N-methylcarbamoylcysteine (AMCC was measured by means of high-performance liquid chromatography. Results: Time weighted average (TWA concentration of the DMF in workplace was 18.6 (range: 9.8–36.2 mg/m3. The concentration of the AMCC in workers’ urine was 28.32 (range: 1.8–58.6 mg/l and 9 workers’ AMCC exceeded the biological exposure index (40 mg/l. Thirty-one workers reported gastrointestinal symptoms (abdominal pain, nausea, anorexia and 10 workers reported headache, dizziness and/or palpitation in the exposed group. Serum analysis revealed that both the mean of serum activities of liver enzymes (ALT, AST and c-GT and the percentage of workers with abnormal liver function were significantly higher in the exposed group as compared to the controls. Conclusions: Dimethylformamide can cause liver damage even if air concentration is in the sub-threshold limit value (sub-TLV level. The protection of skin contact against the exposure to the DMF might be a critical issue as far as the occupational health is concerned.

    Recently, a number of reports have been published on silicosis in workers exposed to artificial quartz conglomerates containing high levels of crystalline silica particles (70-90%) used in the construction of kitchen and bathroom surfaces. Three cases of silicosis in workers exposed to artificial quartz conglomerates are reported. The diagnosis was derived from both the International Labour Office and the International Classification of HRCT for Occupational and Environmental Respiratory Diseases (ICOERD) classifications and cytological analysis of bronchoalveolar lavage fluid. In 2 cases, levels of respirable silica greatly in excess of recommended standards were measured in the workplace, and cytological analysis of bronchoalveolar lavage fluid highlighted a prevalence of lymphocytes, meeting criteria for the diagnosis of accelerated silicosis. The prevention of pneumoconiosis caused by the use of innovative materials, such as artificial conglomerates with high crystalline silica content must be addressed. PMID:26410340

  12. Cancer risks in workers exposed to radiofrequency and microwave radiation: an epidemiologic study

    International Nuclear Information System (INIS)

    Radiofrequency (RF) and microwave (MW) radiations can penetrate human tissue as and exert various bioeffects at relatively low field power densities. In workers exposed occupationally to RF/MW, radiation development of various functional abnormalities of neural, immune, or cardiovascular systems is also possible. Experimental investigations revealed the possibility of epigenetic activity of certain MW exposures, but there exist single epidemiological studies which indicate increased mortality of neoplasms in workers exposed to microwave radiation. As an example, the multi year study of cancer morbidity in Polish military personnel are presented. Despite of the reported increased morbidity of haematopoietic and lymphatic neoplasms, it was not possible to confirm the causal link of the morbidity with exposure to MW radiation

    An expanded cohort study of 74,828 benzene-exposed and 35,805 unexposed workers were followed during 1972 to 1987, based on a previous study in 12 cities in China. A small increase was observed in total cancer mortality among benzene-exposed compared with unexposed Workers (relative risk [RR] = 1-2). Statistically significant excesses were noted for leukemia (RR = 2.3), malignant lymphoma (RR = 4.5), and lung cancer (RR = 1.4). When risks were evaluated by leukemia subtype, only acute myelogenous leukemia was significantly elevated (RR = 3.1), although nonsignificant excesses were also noted for chronic myelogenous leukemia (RR = 2.6) and acute lymphocytic leukemia (RR = 2.3). A significant excess was also found for aplastic anemia. 19 refs., 5 tabs.

    Highlights: • Much lung and pleural pathology is found in chest CT studies. • HRCT signs were screened and subsequent mortality followed up. • Several signs were related to all-cause and disease specific deaths. • The HRCT classification system used was able to predict mortality. • Secondary preventive strategies should be developed for patients with such signs. - Abstract: Objectives: To study associations between chest HRCT signs and subsequent deaths in long-term follow-up. Methods: Lung and pleural signs of 633 asbestos exposed workers (age 45–86, mean 65) screened with HRCT were recorded by using the International Classification of Occupational and Environmental Respiratory Diseases (ICOERD) system, which contains detailed instructions for use and reference images. Subsequent mortality was checked from the national register. Cox regression adjusted for covariates (age, sex, BMI, asbestos exposure, pack-years) was used to explore the relations between HRCT signs and all-cause deaths, cardiovascular and benign respiratory deaths, and deaths from neoplasms – all according to the ICD-10 diagnostic system. Results: The follow-up totalled 5271.9 person-years (mean 8.3 y/person, range .04–10.3). 119 deaths were reported. Irregular/linear opacities, honeycombing, emphysema, large opacities, visceral pleural abnormalities and bronchial wall thickening were all significantly related to all-cause deaths. Most of these signs were associated also with deaths from neoplasms and benign respiratory disease. Deaths from cardiovascular disease were predicted by emphysema and visceral pleural abnormalities. Conclusions: Several HRCT signs predicted deaths. Careful attention should be paid on subjects with radiological signs predictive of deaths and new secondary preventive strategies developed. This calls for further focused studies among different populations.

    Hearing loss is the third most common chronic physical condition in the United States, and is more prevalent than diabetes or cancer (1). Occupational hearing loss, primarily caused by high noise exposure, is the most common U.S. work-related illness (2). Approximately 22 million U.S. workers are exposed to hazardous occupational noise (3). CDC compared the prevalence of hearing impairment within nine U.S. industry sectors using 1,413,789 noise-exposed worker audiograms from CDC's National Institute for Occupational Safety and Health (NIOSH) Occupational Hearing Loss Surveillance Project (4). CDC estimated the prevalence at six hearing impairment levels, measured in the better ear, and the impact on quality of life expressed as annual disability-adjusted life years (DALYs), as defined by the 2013 Global Burden of Disease (GBD) Study (5). The mining sector had the highest prevalence of workers with any hearing impairment, and with moderate or worse impairment, followed by the construction and manufacturing sectors. Hearing loss prevention, and early detection and intervention to avoid additional hearing loss, are critical to preserve worker quality of life. PMID:27101435

  4. Scientific colloquium on medical supervision of workers exposed to ionizing and non ionizing radiations

    International Nuclear Information System (INIS)

    The general principles of medical surveillance for workers exposed to ionizing radiation were defined in the Euratom Basic Standards in 1959. These principles, which are in accordance with the early IGRP publications, have been adopted by the national authorities and implemented without difficulty. However, because of the forthcoming publication of the revised Basic Standards- in accordance with recent IGRP recommendations, the Commission decided to organize a meeting of doctors responsible for the medical surveillance of workers exposed to ionizing radiation in order to disseminate as widely as possible the results of experience gained in the field of radiological protection and to pinpoint the practical difficulties which might arise when the principles were applied. The Commission also considered it important to inform doctors specializing in radiological protection about the principles to be followed by those responsible for the health protection of workers exposed to non-ionizing radiation, particularly microwaves and Laser beams.

  5. Determination of bromine contents in blood and hair of workers exposed to methyl by radioactivation analysis method bromide

    International Nuclear Information System (INIS)

    The bromine contained in blood and hair samples obtained from workers exposed to methyl bromide was analyzed by nondestructive activation analysis. The samples were irradiated for 1 min in pneumatic irradiation facility of Kyoto University research reactor with an estimated thermal neutron flux density at 2 x 1013 n.cm-2.sec-1. The irradiation was counted with Ge(Li) detector. The duration of measurement of radionuclide bromine in blood and hair was 200 sec within 2 - 10 min after irradiation. The bromine content of serum sample obtained from a worker suspected of methyl bromide poisoning was found to be 412 μg/g on 13 days apart from exposure to methyl bromide. The biological half-life of bromine in this case was found to be about 16 days. Then bromine contents in serum and hair samples obtained from workers exposed to methyl bromide were found to be 1.7 and 2.6 times higher respectively than those of nonexposed workers. Any correlations of bromine contents were not observed between serum and hair samples obtained from workers exposed to methyl bromide, nor between bromine amount in the serum of workers exposed to methyl bromide and the terms exposed to it, but statistically significant positive correlation was observed between bromine amount in the hair of workers exposed to methyl bromide and the terms exposed to it.

    Full Text Available Context: The prevalence of occupational health hazards and mortality has been reported to be unusually high among people of India. Although developed countries are very much careful about the health in occupations it is quite neglected in the developing countries like India. Aims: To record PEFR in asymptomatic male workers exposed to chemical fumes for more than 2 years and compare the results with age matched unexposed, healthy male controls. Methods and Material: This was a comparative study between 50 asymptomatic male workers exposed to chemical fumes for more than 2 years in various industries located at Jeedimetla Industrial Area and 50 unexposed healthy male individuals from general population. The sampling was done by simple random sampling (lottery method. The data was collected in the Research Laboratory of Physiology. Anthropometry like weight, height, was measured and the PEFR test was performed in the standing position by taking a deep inspiration and then blowing out as hard and as quickly as possible with their nose closed. Data was analyzed by using SPSS package and was expressed in terms of mean ± SD. Results: It was observed that mean PEFR was statistically highly significant in cases (p = 0.0001, and PEFR decreased with increase in duration of exposure. Conclusions: Thus, it can be concluded that apparently healthy individuals may also have abnormal PEFR findings. Hence, a regular check on these parameters will help them in reducing the chances of its manifestation at a future date.

    Full Text Available Abstract Background Rural township health centres and urban community health centres play a crucial role in the delivery of primary health care in China. Over the past two-and-a-half decades, these health institutions have not been as well developed as high-level hospitals. The limited availability and low qualifications of human resources in health are among the main challenges facing lower-level health facilities. This paper aims to analyse the mobility of health workers in township and community health centres. Methods Data used in this paper come from a nationwide survey of health facilities in 2006. Ten provinces in different locations and of varying levels of economic development were selected. From these provinces, 119 rural township health centres and 89 urban community health centres were selected to participate in a questionnaire survey. Thirty key informants were selected from these health facilities to be interviewed. Results In 2005, 8.1% and 8.9% of health workers left township and community health centres, respectively. The health workers in rural township health centres had three to 13 years of work experience and typically had received a formal medical education. The majority of the mobile health workers moved to higher-level health facilities; very few moved to other rural township health centres. The rates of workers leaving township and community health centres increased between 2000 and 2005, with the main reasons for leaving being low salaries, limited opportunities for professional development and poor living conditions. Conclusion In China, primary health workers in township health centres and community health centres move to higher-level facilities due to low salaries, limited opportunities for promotion and poor living conditions. The government already has policies in place to counteract this migration, but it must step up enforcement if rural township health centres and urban community centres are to retain health

    Full Text Available Introduction Health care facilities in resource-limited settings are faced with numerous challenges including high patient loads and shortage of trained health workers. However, there still remains a dearth of scientific evidence to assess and address issues associated with stress and burnout among health workers providing HIV care. Methods An annual assessment was conducted using a site capacity assessment tool to evaluate the quality of care at 18 HIV health facilities. Questions to determine stress management and HIV care among health workers were graded from 0–5 (lowest to highest score. Data on performance of health facilities were summarized on an excel sheet. Results Majority of the health facilities (67% did not have polices or practices in place to relieve stress faced by staff in providing care for persons with HIV/AIDS.Less than half of the health facilities (44.4% had policies on PEP, confidential HIV testing and counseling as well as referral for care and treatment for staff that are found to be HIV positive. Conclusion Evaluating and addressing issues associated with stress, burnout, as well as providing HIV care services among health workers in HIV settings is imperative for provision of good quality of care.

    Full Text Available Managers in Research and development (R&D are in search of influence because knowledge workers valueautonomy and dislike direct supervision. The purpose of this article is to explore if and how leadership support isconnected to influence. Through interviews with knowledge workers, it is evident that they expect their managerto be supportive and take an interest in them as complete persons. Observations and interviews with managersreveal that they fulfill these expectations by engaging in listening and chatting. In addition, the data alsoillustrates that managers care about their employees. The analysis shows that manager’s activities of care canindeed be a source of social influence, illustrating close connection between emotion and influence. Thisintertwinement should inspire future research to look deeper and broader for potential sources of influence in theleadership process, but also to acknowledge the importance of leadership in the setting of innovation.

    Sex workers in east and southern Africa are exposed to multiple occupational health and safety risks. Detailed understanding of barriers to accessing care would optimise design of improved services for this population. In this study, trained sex workers conducted 55 in-depth interviews and 12 focus group discussions with 106 female, 26 male and 4 transgender sex workers across 6 urban sites in Kenya, Zimbabwe, Uganda and South Africa. Data were analysed thematically, following an interpretive framework. Participants cited numerous unmet health needs, including diagnosis and treatment for sexually transmitted infections and insufficient access to condoms and lubricant. Denial of treatment for injuries following physical assault or rape and general hostility from public-sector providers was common. Resources permitting, many sex workers attended private services, citing higher quality and respect for dignity and confidentiality. Sex workers in southern Africa accessed specialised sex worker clinics, reporting mostly positive experiences. Across sites, participants called for additional targeted services, but also sensitisation and training of public-sector providers. Criminalisation of sex workers and associated stigmatisation, particularly of transgender and male sex workers, hinder HIV-prevention efforts and render access to mainstream healthcare precarious. Alongside law reform, sex worker-led peer outreach work should be strengthened and calls by sex workers for additional targeted services heeded. PMID:23414116

    2006-01-01

    With the workforce growing older and the supply of younger workers diminishing, it is critical for health care managers to understand the factors necessary to capitalize on their vintage employees. Retaining this segment of the workforce has a multitude of benefits including the preservation of valuable intellectual capital, which is necessary to ensure that health care organizations maintain their competitive advantage in the consumer-driven market. Retaining the aging employee is possible if health care managers learn the motivators and training differences associated with this category of the workforce. These employees should be considered a valuable resource of human capital because without their extensive expertise, intense loyalty and work ethic, and superior customer service skills, health care organizations could suffer severe economic repercussions in the near future.

  13. First assessment of individual monitoring of medical workers occupationally exposed to ionizing radiation in Burkina Faso

    International Nuclear Information System (INIS)

    This paper reports the results of monitoring of medical workers occupationally exposed to ionizing radiation as a consequence of exposure to X-rays, from 2007 to 2010, in Burkina Faso. The radiation exposure monitoring was made with thermoluminescent dosimeters (TLD-100) type 0110 and the reader used was Harshaw 4500. The medical establishments. subscribers were provided with personal dosimeters (measuring Hp (10) and Hp (0.07)) and dosimeters for background and workplace exposure (H*10) measurement. The dosimeters have been worn for periods of 2 months each. The number of establishments subscribed and workers monitored has gradually increased from 4 radiology establishments with 13 workers monitored at September 2007 to 23 subscribers with 121 workers monitored at the end of April 2010. 13 establishments were still working without monitoring. From September 2007 to April 2010, no individual annual dose limit has really been reached. 88.16% of the 2 months dose values of personal dosimeters were below 0.1mSv, the detection limit and 96.61% of Hp (10) bimonthly values were below 3.33mSv. The workplace exposure monitoring values were often low (varying from 0.00mSv to 40.45mSv). 87.08% of the values of H*(10) were below 3.33mSv, the upper limit of Hp (10) for a period of 2 months. Low values of individual dose have also been recorded despite of high values of workplace monitoring. This allowed to state that the workers monitored were not exposed to a major risk. Nevertheless, 13 TLD have been lost and 3 damaged by subscribers (out of 1504 TLD provided). 26 times (out of 240), background measurement and workplace exposure monitoring dosimeters have been placed at the improper location. Therefore, sensitization of the establishments using ionizing radiation should be reinforced and the national regulations should impose radiation monitoring (author)

    The study investigates the occurrence and character of skepticism and resistance towards ethnic minority care workers among older care recipients in a municipality in Sweden. Twelve representatives of caregiver organizations were interviewed about their experience of this phenomenon. Three additional interviews were conducted with ethnic minority care workers. Representatives described the problem as rare and mostly occurring as language difficulties or as a temporary problem characterized as a fear of the unknown among some care recipients. They tended to apply a pragmatic or pathologizing approach when talking about causes of and solutions to the problem. These approaches enabled care providers to comply with "potential racism" without challenging an official ideology of anti-racism. In contrast, staff of foreign descent described the problem as more frequent and severe, particularly for short-term employees who experience many first-time encounters with care recipients.

  15. Cytogenetic and hematological studies in the workers occupationally exposed to low levels of ionizing radiation

    International Nuclear Information System (INIS)

    Complete text of publication follows. Objective: This study was aimed at detecting both the incidence of chromosomal aberrations and changes in the hematological parameters as biomarkers of possible radiation injury among workers occupationally exposed to low levels of ionizing radiation and detecting the dose-effect relationship. Methods: Samples of peripheral blood were collected from 38 male industrial radiographers exposed to ionizing radiation for 1-16 years and from 24 age- and sex-matched healthy blood donors without radiation history served as control group. All radiation workers were routinely monitored with film badge. Cytogenetic analysis in peripheral blood lymphocytes assessed by the conventional chromosome aberration assay and at least 200 metaphases for each person were scored. The collected blood samples were analyzed for hematological assay using an automatic analyzer Sysmex KX-21, where 14 different parameters were computerized. Mann-Whitney U test was used to compare the frequencies of the unstable aberrations and hematological parameters between test and control groups. Dose-effect relationship and the influence of age and duration of employment was tested by regression analysis. Results and conclusion: The mean frequencies of dicentric and acentric chromosome aberrations were significantly higher in the exposed group than in the control group (P< 0.0005). No correlation between chromosomal aberrations and physical dose and age was observed in the exposed group. Also there is no clear relation between chromosome damage and duration of exposure. However, the increase in chromosome aberrations in the exposed group was not followed by a corresponding hematological depression. The average values of hematological indices were within the reference levels and did not show any significant differences with control group. A tendency of decreasing the absolute lymphocyte count within the referential levels was the only hematological effect in radiation

    This study reports a survey of occupational exposure to copper chrome arsenic (CCA) based wood preservatives during vacuum pressure timber impregnation. The survey involved biological monitoring based on analysis of chromium and arsenic in urine samples collected from UK workers. The aim of the study was to determine the extent of occupational exposure to arsenic and chromium in the UK timber treatment industry. The objectives were to collect and analyse urine samples from as many workers as possible, where CCA wood preservatives might be used, at 6 monthly intervals for 2 years. In addition, to investigate day-to-day variations in urinary excretion of chrome and arsenic by collecting and analysing three samples a week for 3 weeks in subsets of workers and controls (people not occupationally exposed). All urine samples were analysed for chromium and inorganic arsenic. To investigate any residual interference every sample was accompanied by a short questionnaire about recent consumption of seafood and smoking. The analytical methods for arsenic used a hydride generation technique to reduce interference from dietary sources of arsenic and also a technique that would measure total arsenic concentration in urine. The main findings show that workers exposed to CCA wood preservatives have concentrations of inorganic arsenic and chromium in urine that are significantly higher than those from non-occupationally exposed people but below biological monitoring guidance values that would indicate inhalation exposure at UK occupational exposure limits for chromium and arsenic. The effects of consumption of seafood on urinary arsenic were not significant using the hydride generation method for inorganic arsenic but were significant if 'total' arsenic was measured. The 'total' arsenic method could not distinguish CCA workers from controls and is clearly unsuitable for assessment of occupational exposure to arsenic. There was a significant increase in the urinary concentration of

    Full Text Available Pesticides can cause gene mutations and chromosomal aberrations in exposed individuals. We have investigated 24 workers exposed to pesticides. Clinical examinations and cytogenetic and toxicological tests were performed. Ten non-exposed individuals were used as controls. Toxicological dosages of copper, zinc and manganese (metals found in some pesticides, hepatic enzyme dosage (GOT, GPT, AR and acetylcholinesterase activity were performed in 16 workers and 8 controls. In the exposed workers, the most relevant clinical symptoms were poor digestion with fullness sensation after meals, irritated eyes, headache and fasciculations. The exposed group showed significantly lower manganese dosage and acetylcholinesterase activity, and significantly higher levels of alkaline phosphatase. Cytogenetic studies showed significantly higher chromosomal aberrations in the exposed group compared to the control group. Although the workers used protection against the pesticide's fog, the results revealed that the workers were contaminated with the pesticides. Therefore, the cytogenetic, toxicological studies with clinical examination are necessary for monitoring workers who are exposed to pesticides in any situation.

    Task shifting, which involves the transfer of care work from regulated health-care professionals to home care workers (HCWs), is a strategy to ensure the efficient delivery of home care services in Canada and internationally. Using a feminist political economy approach, this paper explores the effects of task shifting on HCWs' skills. Task shifting may be understood as a form of downward substitution-and an effort to increase control over workers while minimizing costs-as some of health-care professionals' responsibilities are divided into simpler tasks and transferred to HCWs. Our interviews with 46 home health-care providers in Ontario, which focused explicitly on HCWs' role in care provision, problematize the belief that "low skilled" care workers have little control over their work. HCWs' skills become more complex when they do transferred tasks, and HCWs sometimes gain greater control over their work. This results in increased autonomy and mastery for many HCWs. In turn, this serves to reinforce the intrinsic rewards of care work, despite the fact that it is low paid and undervalued work. PMID:26286959

    Results of a recent molecular epidemiological study of 1,3-butadiene (BD) exposed Czech workers, conducted to compare female to male responses, have confirmed and extended the findings of a previously reported males only study (HEI Research Report 116, 2003). The initial study found that urine concentrations of the metabolites 1,2-dihydroxy-4-(acetyl) butane (M1) and 1-dihydroxy-2-(N-acetylcysteinyl)-3-butene (M2) and blood concentrations of the hemoglobin adducts N-[2-hydroxy-3-butenyl] valine (HB-Val) and N-[2,3,4-trihydroxy-butyl] valine (THB-Val) constitute excellent biomarkers of exposure, both being highly correlated with BD exposure levels, and that GST genotypes modulate at least one metabolic pathway, but that irreversible genotoxic effects such as chromosome aberrations and HPRT gene mutations are neither associated with BD exposure levels nor with worker genotypes (GST [glutathione-S-transferase]-M1, GSTT1, CYP2E1 (5' promoter), CYP2E1 (intron 6), EH [epoxide hydrolase] 113, EH139, ADH [alcohol dehydrogenase]2 and ADH3). The no observed adverse effect level (NOAEL) for chromosome aberrations and HPRT mutations was 1.794 mg/m(3) (0.812 ppm)--the mean exposure level for the highest exposed worker group in this initial study. The second Czech study, reported here, initiated in 2003, included 26 female control workers, 23 female BD exposed workers, 25 male control workers and 30 male BD exposed workers (some repeats from the first study). Multiple external exposure measurements (10 full 8-h shift measures by personal monitoring per worker) over a 4-month period before biological sample collections showed that BD workplace levels were lower than in the first study. Mean 8-h TWA exposure levels were 0.008 mg/m(3) (0.0035 ppm) and 0.397 mg/m(3) (0.180 ppm) for female controls and exposed, respectively, but with individual single 8-h TWA values up to 9.793 mg/m(3) (4.45 ppm) in the exposed group. Mean male 8-h TWA exposure levels were 0.007 mg/m(3) (0.0032 ppm

    Full Text Available Abstract Background Health care workers are exposed to patients with tuberculosis and are at risk of nosocomial infection. The aim of this study was to determine the prevalence and factors associated with latent tuberculosis infection among health care workers in Malaysia and also to evaluate the agreement between Quantiferon TB Gold in tube test with Tuberculin Skin Test. Methods A cross sectional study was conducted at four randomly selected hospitals in the Klang Valley from December 2008 to May 2009. Self administered questionnaire was used to obtain information on health care workers and possible risk factors. The response rate for this study was 90.8% with 954 respondents completed the questionnaire and were tested with Quantiferon TB Gold in tube for latent tuberculosis infection. Agreement between Quantiferon TB Gold in tube and Tuberculin Skin Test was assessed among 95 health care workers who consented to undergo both tests. Results The overall prevalence of latent tuberculosis infection among health care workers was 10.6% (CI: 8.6%; 12.6%. Factors significantly associated with latent tuberculosis infection were aged 35 years and older [9.49 (CI: 2.22; 40.50], history of living in the same house with close family members or friends who had active tuberculosis [8.69 (CI: 3.00; 25.18], worked as a nurse [4.65 (CI: 1.10; 19.65] and being male [3.70 (CI: 1.36; 10.02]. Agreement between Quantiferon TB Gold in tube test and tuberculin skin test at cut-off points of 10 mm and 15 mm was 50.5% and 82.1% respectively. However, Kappa-agreement was poor for both cut-off points. Conclusion The prevalence of latent tuberculosis infection in Malaysia was relatively low for an intermediate TB burden country. We could not comment on the occupational risk of latent tuberculosis infection among health care worker compared to the general population as there were no prevalence data available for latent tuberculosis infection in the general population

  4. Hematology evaluation in workers exposed to ionizing radiation of a radiotherapy service

    International Nuclear Information System (INIS)

    The verification of hematology indicators is performed as a routine at the initial and periodic evaluation of the health of workers which are exposed to ionizing radiation. In order to analyze the behavior of such indicators in connection with the exposure time and the received dose, a sample (n=74) of workers of the Radiotherapy Service in the Cancer Hospital in La Habana has been studied during 8 years. It was observed that the mean number of leucocytes, blood platelet and hemoglobin did not show meaningful variations and oscillated into normal limits; however an increase in the number of leukopenia cases was detected when the exposure time and the accumulated dose increased. This increase was two, three times higher in the last year of pursuit in connection with the initial value. (authors). 8 refs., 2 figs., 3 tabs

    A neurophysiological study was carried out to examine peripheral neurotoxicity of extremely low levels of CS/sub 2/, that is, less than 2 ppm (TWA-8hr) among Chinese viscose rayon workers. From the subjects who participated in a 1981 cross-sectional medical survey, 70 male workers exposed to CS/sub 2/ and age-matched unexposed workers were randomly selected for the present neurophysiological examination. The conduction velocities of motor, sensory and slower motor fibres of the right ulnar nerve were measured using the same methods as those in the study by Seppaelaeinen (1974). Skin temperature was measured at the middle of the volar surface of the right forearm with a Thermistor thermometer. According to an earlier occupational hygiene survey in the plant, current personal exposures determined by a passive dosimeter method were very low; the average of daily exposure of 7 jobs studied was 1.45 ppm (range 0.2-5.0). Past and current area sampling data also suggested that occupational hygiene conditions regarding CS/sub 2/ exposure in the plant had been extremely good for the previous 6 years. The present neurophysiological study clearly showed that significant reduction in the conduction velocities of motor and slower motor fibres of the ulnar nerve was detected as a consequence of chronic exposure to low levels of CS/sub 2/. In the previous cross-sectional medical survey, no retinopathy was found among Chinese workers exposed to CS/sub 2/ at this level. These results suggested that an effect of CS/sub 2/ on the peripheral nerve would appear earlier than that on the retina.

    The purpose of this study was to determine the prevalence and characteristics of tinnitus and assess the relationship between tinnitus and hearing loss among firefighters and operating engineers, who are exposed to noise on-the-job. The study analyzed existing data from two different populations (154 firefighters and 769 operating engineers) who completed a survey and audiometric tests as part of a hearing loss prevention intervention study. Approximately 40% of both groups reported tinnitus; 34% of firefighters and 59% of operating engineers showed hearing loss at noise-sensitive frequencies (4 kHz and 6 kHz). Firefighters with high frequency hearing loss (odds ratio [OR] = 2.31; 95% confidence interval [CI] = [1.05, 5.11]) and those with perceived impaired hearing status (OR = 3.53; 95% CI = [1.27, 9.80]) were significantly more likely to report tinnitus. Similarly, operating engineers who had hearing loss at both low (OR = 2.10; 95% CI = [1.40, 3.15]) and high frequencies (OR = 2.00; 95% CI = [1.37, 2.90]), and perceived impaired hearing status (OR = 2.17; 95% CI = [1.55, 3.05]) were twice as likely to report tinnitus. This study demonstrated that tinnitus is a considerable problem for noise-exposed workers. Workers with hearing loss demonstrated significantly higher rates of tinnitus. Comprehensive workplace hearing conservation programs should include tinnitus management for noise-exposed workers, along with other key elements such as noise control and hearing protection.

    To research the effect of 27.2 MHz radiofrequency radiation on electrocardiograms (ECG), 225 female workers operating radiofrequency machines at a shoe factory were chosen as the exposure group and 100 female workers without exposure from the same factory were selected as the control group. The 6 min electric field strength that the female workers were exposed to was 64.0 ± 25.2 V/m (mean ± SD), which exceeded 61 V/m, the International Commission on Non-Ionizing Radiation Protection reference root mean square levels for occupational exposure. A statistical difference was observed between the exposed group and the control group in terms of the rate of sinus bradycardia (χ(2)  = 11.48, P = 0.003). When several known risk factors for cardiovascular disease were considered, including smoking, age, alcohol ingestion habit, and so on, the exposure duration was not an effective factor for ECG changes, sinus arrhythmia, or sinus bradycardia according to α = 0.05, while P = 0.052 for sinus arrhythmia was very close to 0.05. We did not find any statistical difference in heart rate, duration of the QRS wave (ventricular depolarization), or corrected QT intervals (between the start of the Q wave and end of the T wave) between the exposed and control groups. Occupational exposure to radiofrequency radiation was not found to be a cause of ECG changes after consideration of the confounding factors. PMID:23280584

    A morbidity of 600 female twister operators was exposed to a long-standing (over 20 years) study and manifold statistic analysis, data of which are represented. The vascular disorders appeared to correlate with the occupational deafness formation. Cerebral resistance recording (CRR) and EEG in 120 workers with various deafness degrees demonstrated the different grades of impaired cerebral and peripheral blood flow. The manifold analysis and CRR produced basic data so as to classify the vasculogenic lesions caused by the exposure to noise and to evaluate the occupational disablement. PMID:8061961

    The challenge of hiring and retaining well-trained caregivers for the growing numbers of elders in need of care is a global concern. This study was designed to understand the views of direct care workers and included 15 nurse aides and med techs working in an assisted living and special care assisted living community for people with dementia. Each participant was provided with a digital camera and asked to take photographs "to show what caregiving means to you." Analysis is based on group discussions about the full set of photographs created by the direct care workers and individual written and oral narratives about four photographs chosen by each participant. The categories generated from these data represent the direct care workers' perceptions of the approaches to quality caregiving and the relationships involved in doing their jobs well. By focusing on the essential relationships and interactions, rather than primarily on the required care, we can begin to imagine the caregiving experience in terms of a communal rather than an institutional experience. We can then productively turn our focus to the people involved rather than emphasize their roles as providers or recipients of care. PMID:22539061

    In Swaziland, the health care system is experiencing severe scarcity of health care workers (HCWs) due to difficult working conditions, migration and the human immunodeficiency virus (HIV) pandemic. Nurses and other HCWs in Swaziland are personally as affected by communicable diseases as the general population. High levels of HIV and TB co-infection bring added complexity to care. The loss of skilled staff in key positions has had a particularly negative impact on the quality of care and service delivery. The Swaziland Nurses Association (SNA) has established a Centre for Comprehensive Wellness for HCWs in the public and private sector and their immediate families to support the health workforce.

    A case is described of chickenpox acute respiratory distress syndrome in an ambulance driver after the inter-hospital transfer of a patient known to have chickenpox pneumonia. Following this exposure, he neither avoided patient contact nor received varicella zoster immune globulin. He subsequently required 13 days of ventilatory support before making a full recovery. The case described supports the contention that health care workers should be screened by serology for immunity to chickenpox before patient contact occurs, with subsequent vaccination of those who are non-immune, when the vaccine becomes available.

  19. Germline minisatellite mutations in workers occupationally exposed to radiation at the Sellafield nuclear facility

    International Nuclear Information System (INIS)

    Germline minisatellite mutation rates were investigated in male workers occupationally exposed to radiation at the Sellafield nuclear facility. DNA samples from 160 families with 255 offspring were analysed for mutations at eight hypervariable minisatellite loci (B6.7, CEB1, CEB15, CEB25, CEB36, MS1, MS31, MS32) by Southern hybridisation. No significant difference was observed between the paternal mutation rate of 5.0% (37 mutations in 736 alleles) for control fathers with a mean preconceptional testicular dose of 9 mSv and that of 5.8% (66 in 1137 alleles) for exposed fathers with a mean preconceptional testicular dose of 194 mSv. Subgrouping the exposed fathers into two dose groups with means of 111 mSv and 274 mSv revealed paternal mutation rates of 6.0% (32 mutations in 536 alleles) and 5.7% (34 mutations in 601 alleles), respectively, neither of which was significantly different in comparisons with the rate for the control fathers. Maternal mutation rates of 1.6% (12 mutations in 742 alleles) for the partners of control fathers and 1.7% (19 mutations in 1133 alleles) for partners of exposed fathers were not significantly different. This study provides evidence that paternal preconceptional occupational radiation exposure does not increase the germline minisatellite mutation rate and therefore refutes suggestions that such exposure could result in a destabilisation of the germline that can be passed on to future generations.

  20. Cytogenetic Status of Workers Occupationally Exposed to Microwave Radiation of GEM Radar

    International Nuclear Information System (INIS)

    Aim of the present study was to analyzed cytogenetic status of workers occupationally exposed to damaging effects of microwave radiation of GEM radar. Microwave radiation of GEM radar acts within microwave field of 10 μW/cm2 to 10 mW/cm2 and frequency range of 1.5 GHz to 10.9 GHz that has contradictory cytogenetic effect on human genome. For that reason we used two methods commonly used in this type of monitoring research: comet assay and micronucleus test. We measured the baseline comet assay effect in whole blood samples and in corresponding unexposed control subjects. It was found that in the subjects who were occupationally exposed to microwave radiation, the levels of DNA damage increased compare to control group and showed interindividual variations. In addition we studied parameters of the micronucleus test were the levels of micronuclei also increased and showed interindividual variations. In addition, new parameters that were measured; nucleoplasmic bridges and nuclear buds, were detected in exposed group in compare to control group that did not shown this type of damage. All differences between mean group values were statistically significant (P less than 0.05) in compare to control unexposed group. Results of our study indicate that individuals occupationally exposed to microwave frequency of GEM radar equipment may experience an increased genotoxic risk, emphasizing the importance of individual biomonitoring to prevent any hazard to their health.(author)

    Objective To assess the effect of benzene on sperm DNA damageMethods Twenty-seven benzene-exposed workers were selected as exposed groupand 35 normal sperm donors as control group. Air concentration of benzene series inworkshop was determined by gas chromatography. As an internal exposure dose ofbenzene, the concentration of trans, trans-muconic acid (ttMA) was determined byhigh performance liquid chromatography. DNA was detected by modified single cellgel electrophoresis (SCGE).Results The air concentrations of benzene, toluene and xylene at the workplace were86.49 ± 2.83 mg/m3, 97.20 ±3.52 mg/m3 and 97.45 ±2.10 mg/m3, respectively.Urinary ttMA in exposed group (1.040 ± 0.617 mg/L) was significantly higher thanthat of control group (0.819 ± 0.157 mg/L). The percentage of head DNA, determinedby modified SCGE method, significantly decreased in the exposed group (n=13, 70.18%± 7.36%) compared with the control (n=16, 90.62% ± 2.94%)(P<0.001).Conclusion The modified SCGE method can be used to investigate the damage ofsperm DNA. As genotoxin and reprotoxins, benzene had direct effect on the germ cellsduring the spermatogenesiss.

  2. Compensation for damage to workers health exposed to ionizing radiation in Argentina

    International Nuclear Information System (INIS)

    The objective of this report is to analyze the possibility to establish a scheme to compensate damage to workers health exposed to ionizing radiation in Argentina for those cases in which it is possible to assume that the exposure to ionizing radiation is the cause of the cancer suffered by the worker. The proposed scheme is based on the recommendations set out in the 'International Conference on Occupational Radiation Protection: Protecting Workers against Exposure to Ionization Radiation, held in Geneva, Switzerland, August 26-30, 2002. To this end, the study analyzes the present state of scientific knowledge on cancer causation due to genotoxic factors, and the accepted form of the doses-response curve, for the human beings exposure to ionization radiation at low doses with low doses rates. Finally, the labor laws and regulations related to damage compensation; in particular the present Argentine Labor Law; the National Russian Federal Occupational Radiological Health Impairment and Workmen Compensation, the United Kingdom Compensation Scheme for Radiation-linked Diseases and the United States Energy Employees Occupational Illness Compensation Program are described.

    The aim of this study was to find out if occupational exposure to dust, fumes or gases, especially among never-smokers, increased the mortality from chronic obstructive pulmonary disease (COPD). A cohort of 317,629 Swedish male construction workers was followed from 1971 to 1999. Exposure to inorganic dust (asbestos, man-made mineral fibres, dust from cement, concrete and quartz), gases and irritants (epoxy resins, isocyanates and organic solvents), fumes (asphalt fumes, diesel exhaust and metal fumes), and wood dust was based on a job-exposure matrix. An internal control group with "unexposed" construction workers was used, and the analyses were adjusted for age and smoking. When all subjects were analysed, there was an increased mortality from COPD among those with any airborne exposure (relative risk 1.12 (95% confidence interval (CI) 1.03-1.22)). In a Poisson regression model, including smoking, age and the major exposure groups, exposure to inorganic dust was associated with an increased risk (hazard ratio (HR) 1.10 (95% CI 1.06-1.14)), especially among never-smokers (HR 2.30 (95% CI 1.07-4.96)). The fraction of COPD among the exposed attributable to any airborne exposure was estimated as 10.7% overall and 52.6% among never-smokers. In conclusion, occupational exposure among construction workers increases mortality due to chronic obstructive pulmonary disease, even among never-smokers. PMID:15065829

    Imidacloprid is a relatively new insecticide in neonicotinoids chemical class with neuroactivity in insects, being one of the most widely used insecticides in the world. For biomonitoring in workers exposed to pesticides, the authors designed a method detecting low levels of Imidacloprid in urine of operators, based on tandem liquid mass-spectrometry with ionization source--electrostatic dispersion (positive ionization) in multi-reaction monitoring regime with subsidiary ion (mass/charge) 209 for quantitative assessment and ion 175.1 for confirmation onion ratio. The study incorporated diurnal urine, about 100 ml of average sample was frozen and kept at temperature -20C for analysis. Before extraction, the sample was unfrozen, an aliquot of 5 ml was selected, diluted with 5 ml of 0.1% formic acid. The substance was concentrated out of the urine samples via solid-phase extraction with application of cartridges based on octadecylsilane, eluition--1 ml of methanol. Lower limit of Imidacloprid detection in urine is 0.02 ng/ml, of the quantitative assessment--0.1 ng/ ml, linear range of concentrations measured 0.1-10 ng/ml. The method was tested for monitoring in workers exposed to Imidacloprid preparations in natural conditions of pesticides application in agriculture, with various processing technologies. Imidacloprid was identified in urine of two professional operators after work in seed treatment and the subsequent seeding at lower limit of detection (0.02 ng/ml) and 0.34 ng/ml. PMID:27265938

    Full Text Available Rounded atelectasis (RA is a benign and unusual form of subpleural lung collapse that has been described mostly in asbestos-exposed workers. This form of atelectasis manifests as a lung nodule and can be confused with bronchogenic carcinoma upon conventional radiologic examination. The objective of the present study was to evaluate the variation in contrast uptake in computed tomography for the identification of asbestos-related RA in Brazil. Between January 1998 and December 2000, high-resolution computed tomography (HRCT was performed in 1658 asbestos-exposed workers. The diagnosis was made in nine patients based on a history of prior asbestos exposure, the presence of characteristic (HRCT findings and lesions unchanged in size over 2 years or more. In three of them the diagnosis was confirmed during surgery. The dynamic contrast enhancement study was modified to evaluate nodules and pulmonary masses. All nine patients with RA received iodide contrast according to weight. The average enhancement after iodide contrast was infused, reported as Hounsfield units (HU, increased from 62.5 ± 9.7 to 125.4 ± 20.7 (P < 0.05, with a mean enhancement of 62.5 ± 19.7 (range 40 to 89 and with a uniform dense opacification. In conclusion, in this study all patients with RA showed contrast enhancement with uniform dense opacification. The main clinical implication of this finding is that this procedure does not permit differentiation between RA and malignant pulmonary neoplasm.

  6. Assessment of methodology for 131I determination in workers exposed to incorporation

    International Nuclear Information System (INIS)

    In this work a technique used to monitor internal contamination of workers exposed to Iodine-131 incorporation from Radioisotope Production Plant was assessed. For the measurements of workers a NaI(Tl) EG and G ORTEC 905-1 were used in specific geometry, and data acquisition was controlled with MaestroTM software. Phantom has been used for calibration of efficiency of detectors placed in the same position as the real monitored person. Moreover, background counting was evaluated by statistical analysis for determination of protocol counting. The results obtained were analyzed under two models for calculating the decision threshold (Lc), and the minimum detectable activity (MDA), finally total uncertainty was calculated. Mean of efficiency was de 0.13% (RSD 6.7%) N = 43 D 6,7%, the MDA was 224 Bq (95% NC), and total propagated uncertainty was ± 13%. We obtained an effective evaluation of thyroid monitoring system for measurement of Iodine-131 in occupationally exposed persons. (author)

    We previously investigated bladder cancer risk in a cohort of dyestuff workers who were heavily exposed to aromatic amines from 1922 through 1972. We updated the follow-up by 14 years (through 2003) for 590 exposed workers to include more than 30 years of follow-up since last exposure to aromatic amines. Expected numbers of deaths from bladder cancer and other causes were computed by use of national mortality rates from 1951 to 1980 and regional mortality rates subsequently. There were 394 deaths, compared with 262.7 expected (standardized mortality ratio = 1.50, 95% confidence interval = 1.36 to 1.66). Overall, 56 deaths from bladder cancer were observed, compared with 3.4 expected (standardized mortality ratio = 16.5, 95% confidence interval = 12.4 to 21.4). The standardized mortality ratio for bladder cancer increased with younger age at first exposure and increasing duration of exposure. Although the standardized mortality ratio for bladder cancer steadily decreased with time since exposure stopped, the absolute risk remained approximately constant at 3.5 deaths per 1000 man-years up to 29 years after exposure stopped. Excess risk was apparent 30 years or more after last exposure. PMID:20548022

  9. Dose evaluation in occupationally exposed workers through dosimeters ring and wrist type with an anthropomorphic phantom

    International Nuclear Information System (INIS)

    In the Nuclear Medicine service of the Clinica San Pablo (Peru), the occupationally exposed workers carried out the preparation and administration of radiopharmaceuticals to patients, so it is vital to measure the equivalent dose to the hands during the procedures in order to optimize the exposure to the ionizing radiation and execute the Radiological Safety Regulation (D.S. No. 009-97-Em) and the standard IR 002.2012 of radiation protection and safety in nuclear medicine. In this paper was designed and built a hand anthropomorphic phantom made of paraffin following the description given for the standard man, later were placed dosimeters ring and wrist type UD-807 model, Panasonic brand. Then we proceeded to irradiate using vial containers of Tc-99 and I-131. The obtained results showed the difference between the equivalent dose obtained among the ring and wrist dosimeter also getting a dose of 153 mSv /year when working with 99mTc and of 61 mSv /year when working with iodine-131. Was also demonstrated that the ring dosimeter shows the average dose received in the hand with less dispersion. It was found that under the national regulation on Requirements of Radiation Protection and Nuclear Safety in Medicine article 63, indicates that higher doses of 150 mSv /year the occupationally exposed workers should have hand dosimetry. Finally the individual dose limit of 500 mSv /year in extremities can be overcome if adequate radiation protection standards do not apply. (author)

    Background Circulating microRNAs (miRNAs) have attracted interests as non-invasive biomarkers of physiological and pathological conditions. Several studies have examined the potential effects of mercury exposure on miRNAs expression profiles of general population environmentally exposed to mercury. The objective is to identify mercury-related miRNAs of female workers occupationally exposed to mercury. Methods In this case-control study, we used a microarray assay to detect the miRNA expression profiles in pooled plasma samples between (I) chronic mercury poisoning group; (II) mercury absorbing group and (III) control group in the discovery stage. Each group has ten individuals. In addition, we conducted a validation of eight candidate miRNAs in the same 30 workers by quantitative real-time PCR. Results In the discovery stage, eight miRNAs were conformed following our selection criteria. In the validation stage, RT-PCR confirmed up-regulation of miR-92a and miR-486 in the mercury poisoned group (Pmercury exposure. However, further studies are necessary to prove the causal association between miRNAs changes and mercury exposure, and to determine whether these two miRNAs are clear biomarkers to mercury exposure.

    The majority of Vietnamese Australians migrated to Australia as refugees to escape a war and this unique migration background may affect their ability to access and utilize healthcare services in Australia. Inability to utilize dementia services is associated with higher levels of caregiver burden, higher rates of morbidities and mortality and hospitalization. The aim of the study was to explore the perceived challenges of dementia care from Vietnamese family caregivers and Vietnamese care workers. Gadamer's philosophical hermeneutics was used to interpret and describe the experiences of the participants. Data were collected from in-depth interviews with six Vietnamese family caregivers and a focus group with Vietnamese care workers using purposive sampling. Participants were recruited from a Vietnamese community care organization in South Australia. Five themes were identified from the data analysis namely: (1) a need for culturally and linguistically appropriate dementia education programs; (2) a willingness and unwillingness to seek help; (3) poor knowledge of health care service availability related to dementia; (4) the effect of language barrier in accessing services; and (5) the main sources of services utilized. The study revealed that Vietnamese family caregivers and Vietnamese care workers held different views on the association of stigma with dementia. Findings also revealed factors that impacted accessing and utilizing dementia services. These findings facilitate a more comprehensive understanding of Vietnamese family caregivers' needs and have implications for developing individualized support for family caregivers and for consumer-directed dementia services in Australia.

    Full Text Available Introduction: Health care workers (HCWs are at risk of needlestick injuries (NSIs due to the environment in which they work. Prevention is associated with the combination of availability of special retractable needle syringes, safety boxes, educational intervention, as well as supporting policy. This report is a part of a larger study which assessed the level of multifocused intervention for NSI and prevalence of NSIs among HCWs in State Specialist Hospitals, Ondo State of Nigeria. Materials and Methods: This cross-sectional study was conducted among 642 HCWs comprising doctors, nurses, laboratory workers, and health attendants in selected hospitals. The study utilized structured questionnaire to assess experiences of NSIs, associated activities with injury and documentation. Results: Five hundred and twenty questionnaires retrieved were adequate for analysis NSIs were reported by 290 (55.8% of the HCWs made up of 77.6% doctors, 68.3% nurses, 51.4% laboratory workers, and 30.0% health attendants. Syringe needles were responsible for 68.5% of all injuries. Activities associated with most injuries were the administration of intramuscular injections (52.4%. About half (51.4% of injuries occurred during use while 23.4% of injuries were disposal related. Ninety-three (32.1% of the devices causing injury had been previously used. Only 25% of those injured reported the injury to appropriate authority. Conclusion: These findings implicate the need for a multifocused intervention to disabuse reuse of devices and encourage reporting of injuries.

    1989-01-01

    To evaluate the usefulness of aesthesiometric threshold testing in the quantitative assessment of peripheral sensorineural disorders occurring in the hand-arm vibration syndrome, two point discrimination (TPD) and depth sense perception (DSP) thresholds were measured by means of two aesthesiometers in the fingertips of 65 forestry workers exposed to chain saw vibration and 91 healthy males unexposed to local vibration or neurotoxic chemicals. Among the healthy subjects, divided into three age groups, there was no difference in the mean values of TPD and DSP thresholds. Assuming 1.28 or 2 standard deviations above the mean to be the upper limits of normality, in the present study the threshold values for TPD were 2.5 and 3.13 mm, respectively. Using the same assumptions, the normal threshold values for DSP were 0.36 and 0.49 mm. Among the 65 chain saw operators the prevalence of peripheral sensory disturbances was 70.8%. On the basis of the aesthesiometric results obtained for the group of 46 chain sawyers affected with sensorineural symptoms and a control group of 46 manual workers, the specificity of the aesthesiometric testing method was found to range between 93.4 and 100%, while the sensitivity varied from 52.2 to 71.7%. In its predictive value aesthesiometry had a positive accuracy of 84.6-96.0% and a negative accuracy of 42.8-50.0%. Aesthesiometric testing was able to differentiate between normals and vibration workers with sensory disturbances on a group basis (P less than 0.001), but due to the high rate of false negatives among vibration exposed patients, it was unsuitable to confirm objectively sensorineural symptoms on an individual basis.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2777386

    Burning the sugar cane field before harvesting has a negative impact on both air and human health, however this issue had not been explored in Mexico. The objective of this work was to determine the chromosomal damage in workers from sugar cane burning fields in Sinaloa, México. To this purpose, we analyzed 1000 cells of buccal exfoliated epithelia from 60 exposed workers and 60 non-exposed controls to determine micronucleus frequencies and other nuclear abnormalities. The results indicated significant higher values of micronucleus and nuclear abnormalities such as binucleate cells, pyknosis, karyolysis, chromatin condensation and nuclear buds frequencies in the exposed subjects compared to those that were not exposed.

    Full Text Available Abstract In Tanzania access to urban and rural primary health care is relatively widespread, yet there is evidence of considerable bypassing of services; questions have been raised about how to improve functionality. The aim of this study was to explore the experiences of health workers working in the primary health care facilities in Kilimanjaro Region, Tanzania, in terms of their motivation to work, satisfaction and frustration, and to identify areas for sustainable improvement to the services they provide. The primary issues arising pertain to complexities of multitasking in an environment of staff shortages, a desire for more structured and supportive supervision from managers, and improved transparency in career development opportunities. Further, suggestions were made for inter-facility exchanges, particularly on commonly referred cases. The discussion highlights the context of some of the problems identified in the results and suggests that some of the preferences presented by the health workers be discussed at policy level with a view to adding value to most services with minimum additional resources.

    Full Text Available OBJECTIVE: to learn about the experience of caregivers/mothers providing care to infants exposed to HIV through vertical transmission.METHODS: this qualitative study used Symbolic Interactionism as the theoretical framework. A total of 39 caregivers of children exposed to HIV in follow-up at a specialized service were interviewed. Data were analyzed through inductive content analysis.RESULTS: four categories were identified that report on the lonely experience of handling the child's antiretroviral therapy, mainly due to a lack of information or incomplete information; being attentive to required care, such as the use of prophylaxis for pneumonia, vaccines, and other practices restricted to the mother-child interaction; the desire to omit the HIV out of fear of prejudice and fear of the disease, considering future prospects.CONCLUSION: the HIV and the threat this infection may affect the child cause apprehension and feelings such as fear, guilt and anxiety in the caregivers. Healthcare workers need to work together with mothers so they are able to cope with demands and distress. Only then will the treatment to avoid vertical transmission be efficient and will mother and child be supported during the process, despite apprehension with the outcome.

    Objective To compare the asbestos-induced DNA damage and repair capacities of DNA damage between 104 asbestos exposed workers and 101 control workers in Qingdao City of China and to investigate the possible association between polymorphisms in codon 399 of XRCC1 and susceptibility to asbestosis. Methods DNA damage levels in peripheral bloodlymphocytes were determined by comet assay, and XRCC 1 genetic polymorphisms of DNA samples from 51 asbestosis cases and 53 non-asbestosis workers with a similar asbestos exposure history were analyzed by PCR/RFLP. Results The basal comet scores (3.95±2.95) were significantly higher in asbestos-exposed workers than in control workers (0.10±0.28). After 1 h H2O2 stimulation, DNA damage of lymphocytes exhibited different increases. After a 4 h repair period, the comet scores were 50.98±19.53 in asbestos-exposed workers and 18.32±12.04 in controls. The residual DNA damage (RD) was significantly greater (P<0.01) in asbestos-exposed workers (35.62%) than in controls (27.75%). XRCC1 genetic polymorphism in 104 asbestos-exposed workers was not associated with increased risk of asbestosis. But compared with polymorphisms in the DNA repair gene XRCC1 (polymorphisms in codon 399) and the DNA damage induced by asbestos, the comet scores in asbestosis cases with Gln/Gln, Gln/Arg, and Arg/Arg were 40.26±18.94, 38.03±28.22, and 32.01±11.65, respectively, which were higher than those in non-asbestosis workers with the same genotypes (25.58±11.08, 37.08±14.74, and 29.38±10.15). There were significant differences in the comet scores between asbestosis cases and non-asbestosis workers with Gln/Gln by Student's t-test (P<0.05 or 0.01). The comet scores were higher in asbestosis workers with Gln/Gln than in those with Arg/Arg and in non-asbestosis workers exposed to asbestos, but without statistically significant difference. Conclusions Exposure to asbestos may be related to DNA damage or the capacity of cells to repair H2O2-induced

    significant differences between surface and underground workers were found in this sub-sample with respect to the minor, unidentified adducts that had similar chromatographic properties to 1-NP adducts, and smoking did not have any effect on adduct levels. No significant effects of the genotypes of GSTM1, GSTP1 and GSTT1 on DNA-adducts and on DNA damage as measured by the Comet assay were found in the total study group. The study confirms an increased level of DNA damage in workers exposed to exhaust from truck-driving in the mine. However, the results of the environmental and biological monitoring of 1-NP did not correlate, suggesting that inhalation exposure to diesel exhaust is not reflected by an increase in 1-NP-DNA-adduct levels and/or that factors other than occupational exposure to diesel exhaust are primary determinants of these DNA-adduct levels.

    Increasing concerns about quality of care and workforce shortages have motivated health care organizations and educational institutions to partner to create career ladders for frontline health care workers. Career ladders reward workers for gains in skills and knowledge and may reduce the costs associated with turnover, improve patient care, and/or address projected shortages of certain nursing and allied health professions. This study examines partnerships between health care and educational organizations in the United States during the design and implementation of career ladder training programs for low-skill workers in health care settings, referred to as frontline health care workers. Mixed methods data from 291 frontline health care workers and 347 key informants (e.g., administrators, instructors, managers) collected between 2007 and 2010 were analyzed using both regression and fuzzy-set qualitative comparative analysis (QCA). Results suggest that different combinations of partner characteristics, including having an education leader, employer leader, frontline management support, partnership history, community need, and educational policies, were necessary for high worker career self-efficacy and program satisfaction. Whether a worker received a wage increase, however, was primarily dependent on leadership within the health care organization, including having an employer leader and employer implementation policies. Findings suggest that strong partnerships between health care and educational organizations can contribute to the successful implementation of career ladder programs, but workers' ability to earn monetary rewards for program participation depends on the strength of leadership support within the health care organization.

    Thirty-eight transformer repairmen currently exposed to polychlorinated biphenyls (PCBs), 17 former transformer repairmen, and 56 comparison workers not known to be exposed to PCBs were studied. Measurements were made of serum liver function tests, gamma-glutamyl transpeptidase (GGT), lipid profile, thyroid function tests, and other serum biochemistry; hemoglobin; white cell count; 24-hour excretion of delta-aminolevulinic acid, porphyrins, 17-hydroxycorticosteriods and 17-ketosteroids; sperm count; spirometry; and antipyrine half-life to evaluate microsomal mixed function oxidase induction. The total exposed group differed significantly from the comparison group in albumin, LDH, T4, T4-RT3 index, and actual/predicted FEV1. Significant differences among all three exposure groups were seen for albumin, T4, T4-RT3 index, and 17-hydroxycorticosteroid excretion. Differences in FEV1 were attributable to smoking. Significant correlations between serum PCBs and serum lipids were removed by adjustment for confounding variables. After adjustment for confounding variables, there was a statistically significant positive correlation between serum PCBs and GGT and a negative correlation between adipose PCBs and 17-hydroxycorticosteroid excretion. These may reflect subtle metabolic effects of PCBs.

    The objective of this study was to test the hypothesis that chronic occupational exposure to high temperatures may be detrimental to male reproduction. The study was based on 92 healthy ceramics oven operators with a long exposure to high temperatures, and 87 controls, recruited from the shipment department of the same industry. Interviews with all subjects provided data on sociodemographic characteristics, health status, and fertility problems. Semen analysis was carried out on 46 of the workers exposed to high temperatures, and 14 of the controls, and included evaluation of the sperm concentration, morphology, and motility, including computer-assisted sperm motion analysis (velocity, linearity, ALH, BCF). The results of the questionnaire showed that exposed individuals had a higher incidence of childlessness and of self-reported difficulty in conceiving than controls. The semen analysis showed no significant differences except in sperm velocity. Although differences in semen parameters, taken singly, were not statistically significant, the overall evaluation of the sperm parameters indicated a higher prevalence of pathologic sperm profiles among the exposed compared to the controls.

    The aim of this study was to assess the frequency of chromosomal aberrations-including chromatid type aberrations (CTAs), chromosomal type aberrations, micronucleus (MN) comet assay, and XRCC1 399 Arg/Gln polymorphism-in peripheral blood lymphocytes of workers occupationally exposed to vinyl chloride monomer (VCM). A total of 52 workers and an equal number of controls were recruited into the study to explore the potential cytogenetic risk of occupational exposure to VCM. Questionnaires were administered to obtain details of habitual cigarette-smoking, alcohol-consumption pattern, and occupation, etc. The exposed subjects and controls were classified into two groups based on age (group I 8 and ≥8 years). CTA, MN, and comet assay frequency were significantly greater in polyvinyl chloride (PVC) factory workers (p < 0.05) with long-duration work. CTA, MN, and comet assay values were found to be increased with age in exposed subjects as well as in controls, with exposed subjects showing a statistically greater degree. An extensively greater MN frequency was observed in smokers exposed to VCM than in the control group (P < 0.05). The mean tail length of exposed subjects was greater compared with controls. The study on XRCC1 399 Arg/gln polymorphism in PVC factory workers showed less significant difference in allele frequency compared with controls. In conclusion, this results of work provides evidence for an apparent genotoxic effect associated with VCM exposure. Our results reinforce the greater sensitivity of cytogenetic assays for biomonitoring of occupationally exposed populations. Statistics indicate that workers exposed to VCM are at carcinogenic risk and should be monitored for long-term adverse effects from their exposure. PMID:23271343

  3. The problematic on the cancer development in occupationally exposed workers to ionizing radiations

    International Nuclear Information System (INIS)

    Frequently and in an increasing perspective, the Brazilian Nuclear Energy Commission is inquired on the development of cancer in occupationally exposed workers to ionizing radiation. These workers try to compensate their state of ill health juridically. Taking into account that cancer is a probabilistic effect of radiation, it could be only detected by an increase in cases that normally occur in a particular population. Whether or not the occurrence of the illness is identified as having occupational origin misses scientific consistence. Regarding the probabilistic effect of low level radiation doses, radiation protection is founded on the linear dose-effect without threshold hypothesis. Thus, it could be call into a question: is it possible that the illness, presented by an individual, derives from occupational causes. If the answer is positive, the responsibility can be imputed, at first, to the employer and the link of causality turns out to be fundamented not any more in measurable objective facts but in social, economic, ethic and moral aspects, which arise from the radiological protection quality and measures offered by the employer.

  4. Survival times of women radium dial workers first exposed before 1930

    International Nuclear Information System (INIS)

    Life table methods were applied to survival data on U.S. women radium dial workers in order to compare observed and expected deaths as a function of time after exposure to radium. The study population consisted of 1235 workers employed in the industry before 1930 for whom age and year of death, withdrawal or loss from the study were known. Expected deaths were estimated from age- and time-specific death rates for U.S. white females. The closing year for analysis was 1976, so observation times of 45 to 60 years were possible. For all causes, 529 deaths before age 85 were observed versus 461 expected, and the cumulative survival of the population was significantly less than expected at 10 and more years after first employment. Estimates were made of the net survival probabilities after elimination of risk due to the well-known radium-related malignancies, i.e. bone sarcomas and carcinomas of the paranasal sinuses and the mastoid air cells. There were 455 observed deaths from other causes versus 460 expected, and there was no significant difference between observed and expected cumulative net survival at one-year intervals from zero to 59 years after first employment. These findings indicate that only the known radium-related malignancies contributed significantly to life shortening of the exposed population as a whole, but the presence of other radium-related causes of death may yet be detectable by examination of specific risks as a function of dose.

    Full Text Available Introduction. This year, the World Health Organization focuses on restoring dignity and respect to health care workers. The aim of this study was to investigate the workplace stressors in physicians. Material and Methods. The present study was performed in the period 2002-2004, among physicians treated in the Health Center Novi Sad. The examinees were asked to fill out a questionnaire - a workplace survey - to identify workplace stressors by using a self-evaluation method. The physicians were divided into three groups: those practicing surgery (S, internal medicine (IM and preventive-diagnostics (PD. Statistical analysis was done using SPSS and STATISTICA software. The sample included 208 physicians with an average age of 40 years (SD=7,1; average work experience of 22 years (SD=8,1. Results. 65 physicians from group S and 108 physicians from group IM, identified the following workplace stressors: treating patients in life-threatening situations (47.7%, 30.6%, respectfully; on-call duty (13.8%, 12%; low salary (10.8%, 10.2%; limited diagnostic and therapeutic resources in the IM group. 35 physicians from the DP group identified the following stressors: low salary (25%, treating patients in life-threatening situations and a great number of patients (16%. The analysis of all examined physicians revealed the following workplace stressors: treating patients in life-threatening situations (34.6%, low salary (13%, on-call duty and overtime, and too many patients per physician (11.5%. Conclusion. Restoring the reputation of health workers can be done by providing new equipment to resolve life-threatening situations, by increasing salaries, reducing on-call time, as well as the number of patients. Generally speaking, this should help to improve the quality of work in the health care system, in accordance with the recommendations of the WHO. .

    Full Text Available The aim of the study was to test the influence of noise on the occurrence of thyroid disease. A group of examinees included the noise-exposed workers (300 who work in the production halls and the control group (50 doing administrative jobs in the office. The testing was performed by the service of occupational medicine, within regular control and periodic check-ups of the noise-exposed group and health systematic examinations of the control group. Some laboratory analyses of the thyroid hormone were used for the purpose of this study. The percentage of those with an increased thyroid activity in the control group is 2%, while in the group of workers exposed to noise it equals 6,8%. In the control group, the total number of those with a decreased thyroid function is 0,85% and 4,85% in the noise-exposed group. In the control group, the total number of workers with the changed thyroid function is 2,85%, while in the group exposed to noise, the total number of workers with the changed thyroid function is 11,65%. By comparing the number of workers having disturbances in the thyroid function from the control group to those from the noise-exposed group who have hearing nerve damage, it can be noticed that there is no statistically significant difference. There were 21 examinees that had subjective health complaints with the levels of hormones increased; 15 examinees had subjective health complaints while the levels of hormones were decreased, and 77 examinees had subjective health complaints with the levels of hormones within the normal range. The largest number of workers with a changed thyroid function had between 10 and 20 years of service. After analyzing the results, obtained in both control and noise-exposed groups, the conclusion was that the number of workers having problems with the thyroid activity is larger in the group exposed to noise in relation to the workers from the control group. These values are in correlation with the level of noise

  9. PON1 status does not influence cholinesterase activity in Egyptian agricultural workers exposed to chlorpyrifos

    International Nuclear Information System (INIS)

    Animal studies have shown that paraoxonase 1 (PON1) genotype can influence susceptibility to the organophosphorus pesticide chlorpyrifos (CPF). However, Monte Carlo analysis suggests that PON1 genotype may not affect CPF-related toxicity at low exposure conditions in humans. The current study sought to determine the influence of PON1 genotype on the activity of blood cholinesterase as well as the effect of CPF exposure on serum PON1 in workers occupationally exposed to CPF. Saliva, blood and urine were collected from agricultural workers (n = 120) from Egypt's Menoufia Governorate to determine PON1 genotype, blood cholinesterase activity, serum PON1 activity towards chlorpyrifos-oxon (CPOase) and paraoxon (POase), and urinary levels of the CPF metabolite 3,5,6-trichloro-2-pyridinol (TCPy). The PON1 55 (P ≤ 0.05) but not the PON1 192 genotype had a significant effect on CPOase activity. However, both the PON1 55 (P ≤ 0.05) and PON1 192 (P ≤ 0.001) genotypes had a significant effect on POase activity. Workers had significantly inhibited AChE and BuChE after CPF application; however, neither CPOase activity nor POase activity was associated with ChE depression when adjusted for CPF exposure (as determined by urinary TCPy levels) and stratified by PON1 genotype. CPOase and POase activity were also generally unaffected by CPF exposure although there were alterations in activity within specific genotype groups. Together, these results suggest that workers retained the capacity to detoxify chlorpyrifos-oxon under the exposure conditions experienced by this study population regardless of PON1 genotype and activity and that effects of CPF exposure on PON1 activity are minimal. -- Highlights: ► CPF exposure resulted in an increase in TCPy and decreases in BuChE and AChE. ► CPOase activity decreased in subjects with the PON1 55LM and PON1 55 MM genotypes. ► Neither PON1 genotype nor CPOase activity had an effect on BuChE or AChE inhibition.

    It has been established that coal pneumoconiosis and confluent silicosis are associated with emphysematous changes in the lungs. In the present study, we addressed the concept of emphysema in simple silicosis and asbestosis and in workers exposed to these minerals without the pneumoconiosis. The study was done on 207 consecutive workers evaluated for possible pneumoconiosis at Québec Workman Compensation Board, who had a radiographic reading of pneumoconiosis in the category 0 or 1 of the ILO scale, and in 5 control subjects. Emphysema was detected, typed, and graded on high-resolution CT scans by three independent experienced readers. Age, work experience and industry, smoking habits, and pulmonary function test results were analyzed for possible associations. The subjects were 59 +/- 1 years of age and had mineral dust exposure averaging 26 +/- 1 years; 31 were lifetime nonsmokers and the others were either ex- or current smokers. Ninety-six workers were from primary and 111 from secondary industries and did not differ in any parameter. The CT scan readings for emphysema yielded a 63% complete agreement. In lifetime non-smokers, emphysema was seen in 1 of 20 subjects without pneumoconiosis but in 8 of 11 patients with pneumoconioses. In smokers without pneumoconioses, emphysema was present in 55% of patients with silica exposure, but 29% of patients with asbestos exposure but comparable smoking (p = 0.04). Emphysema type was equally distributed among the groups except for more paracicatricial type in confluent silicosis. Regression analyses documented that age, smoking, exposure type, and presence of pneumoconiosis were significant contribution factors. In the workers without pneumoconiosis, age, smoking, and exposure type (silica) were significant. Emphysema related best with FEV1/FVC ratio, MMEF, and DCO reductions. The prevalence of abnormality of FEV1/FVC ratio was two to five times normal and that of reduced DCO two times normal. We conclude that, in our

    Full Text Available The workers engaged in storage grain handling are exposed to storage grain dust and suffer from different respiratory symptoms like, cough wheezing, chest tightness, eye and nasal irritations. It has been reported abroad and the present study results noted that the grain handlers have allergic symptoms like redness of eyes, itching, sneezing, skin rash, breathlessness and decrement of pulmonary function test values. According to their nature of job, the workers of storage grain godowns were divided into four categories i.e., load handling worker (LHW, ancillary, quality control and depot administration workers. The pulmonary function tests (PFT and the differential count of leucocytes were carried out among the workers by standard technique. Decrement of pulmonary function test values was noted with the increment of blood eosinophil level. The PFT results were presented according to the blood eosinophil level. The decrement of mean PFT values were noticed as the blood level of eosinophil gradually increased from, up to -4%,> 4-10% and above 10%. The maximum numbers of workers in different job categories are belonged to> 4 -10% of eosinophil level. The percentage figure of workers in different departments were LHW 48.38%, (n=45, ancillary 38.88%, (n=7, quality control 54.54% (n=6 and depot administration workers 47.05% (n=16 are belonged to that range.

    There is a paucity of data regarding the association between occupational radiation exposure and risk to human fertility. Recently, we provided the first evidence on altered sperm functional characteristics, DNA damage and hypermethylation in radiation health workers. However, there is no report elucidating the association between seminal plasma antioxidants and sperm chromatin integrity in occupationally exposed subjects. Here, we assessed the seminal plasma antioxidants and lipid peroxidation level in 83 men who were occupationally exposed to ionizing radiation and then correlated with the sperm chromatin integrity. Flow cytometry based sperm chromatin integrity assay revealed a significant decline in αt value in the exposed group in comparison to the non-exposed group (P<0.0001). Similarly, both total and reduced glutathione levels and total antioxidant capacity in the seminal plasma were significantly higher in exposed group than the non-exposed group (P<0.01, 0.001 and 0.0001, respectively). However, superoxide dismutase level and malondialdehyde level, which is an indicator of lipid peroxidation in the seminal plasma, did not differ significantly between two groups. The total antioxidant capacity (TAC) and GSH level exhibited a positive correlation with sperm DNA integrity in exposed subjects. To conclude, this study distinctly shows that altered sperm chromatin integrity in radiation health workers is associated with increase in seminal plasma antioxidant level. Further, the increased seminal plasma GSH and TAC could be an adaptive measure to tackle the oxidative stress to protect genetic and functional sperm deformities in radiation health workers. - Highlights: • Seminal plasma antioxidants were measured in men occupationally exposed to radiation. • Sperm chromatin integrity was significantly affected in the exposed group. • Glutathione and total antioxidant capacity was significantly higher in exposed group. • Sperm DNA damage in exposed subjects

    Gas station attendants and taxi drivers are occupationally exposed to xenobiotics which may be harmful to their health. Atmospheric pollutants and benzene can lead to DNA damage. Genotoxicity and mutagenicity assays can be used to evaluate the effects of these pollutants. We have evaluated genotoxicity and mutagenicity in workers occupationally exposed to xenobiotics, by application of the 8-hydroxy-2-deoxyguanosine (8-OHdG), comet, and micronucleus (MN) assays. Biomarkers of benzene and carbon monoxyde exposure were also measured: urinary t,t-muconic acid (t,t-MA) and carboxyhaemoglobin (COHb) in whole blood, respectively. The study groups comprised 43 gas station attendants (GSA), 34 taxi drivers (TD), and 22 persons without known occupational exposures (NE). Levels of t,t-MA in the GSA group were significantly elevated compared to the NE group (p0.05). DNA damage index (DI) and 8-OHdG levels were significantly higher for both the GSA and TD groups, compared to the NE group (p<0.001), but MN frequencies were not elevated. Spearman correlation analysis showed that the frequency of MN was positively correlated with 8-OHdG. A positive correlation between DNA DI levels and 8-OHdG was also observed. In conclusion, our results indicated that low levels of occupational exposure to benzene and atmospheric pollutants may be linked to genotoxicity and oxidative DNA damage. PMID:25344165

    Our mutagenesis group has been studying with important economic drivers of our state, such as agriculture, the foot-wear and leather industry and open-cast coal mining. Working conditions in these sectors have potentially harmful to humans. The aim of these studies is to determine the health risk of workers by biomonitoring subjects exposed to genotoxic agents. The main results of our studies with vineyard farmers we observed a high rate of MN and DNA damage in individuals exposed to pesticides (p footwear and tannery workers showed a significant increase in the mean ID for the solvent-based adhesive (p < 0.001) group in comparison to the water-based adhesive group and control (p < 0.05). For open-cast coal mine workers, the EBCyt indicated a significant increase in nuclear bud frequency and cytokinetic defects in the exposed group compared to the non-exposed group (p < 0.0001). We were able to associate specific genetic susceptibility with each type of exposure and with the non-use or improper use of personal protection equipment and diet adequacy. These results show how important the continuous education of exposed workers is to minimizing the effect of the occupational exposure and the risk of disease associated with the work. PMID:23413045

    Full Text Available Background : Pesticides are used in agriculture to protect crops, but they pose a potential risk to farmers and environment. The aim of the present study is to investigate the relation between the occupational exposure to various pesticides and the presence of DNA damage. Materials and Methods : Blood samples of 210 exposed workers (after a day of intense spraying and 50 control subjects belonging to various districts of Punjab (India were evaluated using Comet assay. Sixty workers who showed DNA damage were selected for follow up at 5-6 months after the first sampling during a low or null spraying period. Results : Significant differences were found in DNA damage between freshly exposed workers and controls and freshly exposed and followed up cases. There was significant increase in the comet parameters viz. mean comet tail length and frequency of cells showing migration in exposed workers as compared to controls (72.22 ± 20.76 vs. 46.92 ± 8.17, P<0.001; 31.79 vs. 5.77, P<0.001. In the second samples, followed up cases showed significant decrease in frequency of damaged cells as compared to freshly exposed workers of first sampling (P<0.05. The confounding factors such as variable duration of pesticide exposure, age, smoking, drinking and dietary habits etc which were expected to modulate the damage, were instead found to have no significant effect on DNA fragmentation. Conclusion : The evidence of a genetic hazard related to exposure resulting from the intensive use of pesticides stresses the need for educational programs for agricultural workers to reduce the use of chemicals in agriculture.

In the operating rooms, the ionizing radiations are used in orthopaedic surgery and the dose depends on some factors, like the characteristics of the equipment. This study aims to: Estimate the occupational dose of ionizing radiations exposure of the orthopaedic doctors and nurses during the orthopaedic surgeries, in a Portuguese operating room; Sensitize the health care workers to use the individual dosimeter and to adopt radiation preventive measures. 2. Population and methods The study was conducted on nine Orthopaedic doctors and two nurses of an operating room of a hospital in Lisbon neighborhoods. We made a risk evaluating concerning: the radiations dose in different points, corresponding to gonads, hands and crystalline lens levels of all the professionals, during the surgeries; the average period of radiation in the orthopaedic surgeries; the number of annual orthopaedic surgeries, looking for that in the surgeries registers, to estimate the annual ionizing radiations dose of each orthopaedic doctor and nurse. 3. Results The annual doses estimated at different levels for orthopaedic doctors were the following: gonads: between 20,63 and 68,75 mGy; hands: 4,95 16,50 mGy; crystalline lens: 8,25 27,50 mGy).

    2007-09-01

    Full Text Available Abstract Background Casino workers are exposed to high levels of secondhand smoke (SHS at work, yet remain at risk of being excluded from smoke-free legislation around the world. If the prime motivation for smoke-free legislation is the protection of workers, then a workforce experiencing ill-health associated with SHS exposure should not be excluded from legislation. This study aimed to determine the prevalence of respiratory and sensory irritation symptoms among a sample of casino workers, to identify any association between the reporting of symptoms and exposure to SHS at work, and to compare the prevalence of symptoms with that in other workers exposed to SHS. Methods A postal questionnaire survey of 1568 casino workers in London. Using multivariate analysis we identified predictors of respiratory and sensory irritation symptoms. Results 559 workers responded to the questionnaire (response of 36%. 91% of casino workers reported the presence of one or more sensory irritation symptoms in the previous four weeks, while the figure was 84% for respiratory symptoms. The presence of one or more sensory irritation symptoms was most strongly associated with reporting the highest exposure to SHS at work (OR 3.26; 1.72, 6.16. This was also true for reporting the presence of one or more respiratory irritation symptoms (OR 2.24; 1.34, 3.74. Prevalence of irritation symptoms in the casino workers was in general appreciably higher than that reported in studies of bar workers. Conclusion Our research supports the need for comprehensive smoke-free legislation around the world, covering all indoor workplaces including casinos.

    The influence of age, sex and duration of exposure on hearing threshold level (HTL) was assessed in male and female workers exposed to occupational noise. The noise intensities were of 84 and 98 dB(A) continuous equivalent level. Large differences were noted between males and females exposed to 98 dB(A) as well as between males exposed to 98 and 83 dB(A). We concluded that exposure to 98 dB(A) accelerates the evolution of hearing loss, this trend being more pronounced in males. The 83-dB(A) intensity apparently induces a hearing loss above the values due to socioacusis. To evaluate the noxious effect of noise, the HTLs obtained in the group exposed to 98 and 83-dB(A) were compared to those of the non-exposed group of Royster and Thomas. The highest difference was found in males exposed to 98 dB(A).

  5. Analysis of micronuclei of the oral epithelium in workers of a banana zone exposed to pesticides

    International Nuclear Information System (INIS)

    The following study was realized with workers of the zone of Guapiles (Limon, Costa Rica), to determine the possible damage to the genetic material occasioned by labour exhibition to pesticides. The presence of micronuclei in cells of the oral epithelium was used as a biomarcador of effect . Besides, an analysis of frequency of other abnormalities was made in the nucleus of the epithelial cells, which can be an indication of genotoxicity or cytotoxicity. The group of women exposed to pesticides (cases) was formed by workers of packing plants of different independent banana states. The group of women who constituted the group of control were persons that neither them nor their spouses or companions had never worked at agricultural labours and that had not lived inside a banana estate. The samples of the controls were gathered not only from women who are employed at the Hospital of Guapiles, but also from patients who were expecting to be attended in the external consultation of the same hospital, or, in the Healthy Child consultation in the health center of the same city. It is the first time that a study of control-case is done in the country to detect genotoxicidad, using micronuclei of the oral epithelium (MNOE) as a biomarcador. The participants were interviewed to obtain information about his or her customs and family history that could be relevant for the study. The preparation and the analysis of the cells of the oral epithelium of every individual was done in the laboratories of the Instituto de Investigaciones en Salud (INISA), of the Universidad de Costa Rica. Although there are indications of cytotoxic and genotoxicity in the controls showed by an increase of the frequencies of other nuclear abnormalities, the results demonstrated that there is not a significant increase in MNOE's frequency between the group of cases and of controls.

    Personal Dose Equivalent (PDE) values were determined for occupational exposed workers (OEW) at the Nuclear Medicine Department (NMD) of "Instituto Nacional de Cancerología" (INCan), Mexico, using TLD-100 thermoluminescent dosemeters. OEW at NMD, INCan make use of radiopharmaceuticals for diagnosis and treatment of diseases. Radionuclides associated to a pharmaceutical compound used at this Department are 131I, 18F, 68Ga, 99mTc, 111In and 11C with main gamma emission energies between 140 and 511 keV. Dosemeter calibration was performed at the metrology department of "Instituto Nacional de Investigaciones Nucleares" (ININ), Mexico. Every occupational worker used dark containers with three dosimeters which were replaced monthly for a total of 5 periods. Additionally, control dosemeters were also placed at a site free of radioactive sources in order to determine the background radiation. Results were adjusted to find PDE/day and estimating annual PDE values in the range between 2 mSv (background) and 9 mSv. The mean annual value is 3.51 mSv and the standard deviation SD is 0.78 mSv. Four of the 16 OEW received annual doses higher than the average +1 SD (4.29 mSv). Results depend on OEW daily activities and were consistent for each OEW for the 5 studied periods as well as with PDE values reported by the firm that performs the monthly service. All obtained values are well within the established annual OEW dose limit stated in the "Reglamento General de Seguridad Radiológica", México (50 mSv), as well as within the lower limit recommended by the "International Commission on Radiation Protection" (ICRP), report no.60 (20 mSv). These results verify the adequate compliance of the NMD at INCan, Mexico with the norms given by the national regulatory commission.

    Chromium (Cr), being an excellent tanning agent, is widely used in the leather industry and tannery workers (TW) are exposed to it either in the form of inorganic Cr(III) compounds or Cr bound to proteins (leather dust) in the process of leather production. During the present study, the effect of Cr on the hematological indices in TW was evaluated. In this study, hematological indices of 92 male TW aged 20-60 years were compared with 79 control males who hardly had a chance of exposure to chromium. Both groups were subdivided into four age groups with an interval of 10: group A, 20-29 years; group B, 30-39 years; group C, 40-49 years; group D, 50-60 years. Total erythrocyte count (TEC) was significantly lower (p < 0.05) in TW of age group A, B and C than control subjects. Packed cell volume (PCV) was significantly higher (p < 0.05) in TW of age group B while mean corpuscular hemoglobin (MCH) was significantly lower (p < 0.05) in TW of age group D. Within the TW, MCH was significantly lower (p < 0.05) in the age group D as compared to age group A and B. No significant changes were observed in the values of hemoglobin, mean corpuscular volume and mean corpuscular hemoglobin concentration between TW and control individuals. The low values of TEC, PCV and MCH might be a result of chromium exposure in the tannery workers and may act as indicators of chromium toxicity. PMID:21505006

    Frontline workers have a great deal to contribute to improving environmental sustainability of their employers and the health of workers and patients. This article discusses a national project of the Healthcare Career Advancement Program, funded by the U.S. Department of Labor to support green jobs development. Implementation was accomplished through a labor/management collaboration between union locals and 11 employers in four regions throughout the United States. The project developed and implemented a model of training and education for environmental service workers and other frontline health-care workers in hospital settings that supported systems change and built new roles for these workers. It empowered them to contribute to triple bottom line outcomes in support of People (patients, workers, the community), Planet (environmental sustainability and a lower carbon footprint), and Profit (cost savings for the institutions). In the process workers more clearly articulated their important role as a part of the healthcare team and learned how they could contribute to improved patient and worker health and safety.

    Full Text Available Abstract Background The association between chronic respiratory diseases and work disability has been demonstrated a number of times over the past 20 years, but still little is known about work disability in occupational cohorts of workers exposed to respiratory irritants. This study investigated job or task changes due to respiratory problems as an indicator of work disability in pulp mill workers occupationally exposed to irritants. Methods Data about respiratory symptoms and disease diagnoses, socio-demographic variables, occupational exposures, gassing episodes, and reported work changes due to respiratory problems were collected using a questionnaire answered by 3226 pulp mill workers. Information about work history and departments was obtained from personnel files. Incidence and hazard ratios for respiratory work disability were calculated with 95% confidence intervals (CI. Results The incidence of respiratory work disability among these pulp mill workers was 1.6/1000 person-years. The hazard ratios for respiratory work disability were increased for workers reporting gassings (HR 5.3, 95% CI 2.7-10.5 and for those reporting physician-diagnosed asthma, chronic bronchitis, and chronic rhinitis, when analyzed in the same model. Conclusions This cohort study of pulp mill workers found that irritant peak exposure during gassing episodes was a strong predictor of changing work due to respiratory problems, even after adjustment for asthma, chronic bronchitis, and chronic rhinitis.

    The Southern Health and Social Care Trust in Northern Ireland applied a modified version of the Objective Structured Clinical Examination (OSCE) to assess the skills of home care workers in assisting older people taking prescribed medications. In Northern Ireland, home care workers are care workers employed by health and social care trusts or private agencies. The application of the model has developed the skills of this staff group, improved the relationship between the commissioner and provider, significantly reduced the time spent by community nurses in individual training and assessment, and enhanced the patient experience for those taking medication. Overall, the application of this model has provided assurances to the Trust board, the executive director of nursing, and operational directors that home care workers are competent in assisting older people in this high-risk activity.

    To determine whether there was excessive risk of cancer among workers exposed to chrysotile fiber alone by applying a meta-analysis technique. Methods All data meeting the criteria of cohort studies on cancer mortality among workers exposed only to chrysotile were incorporated into meta-analysis. Pooled standardized mortality ratios (SMRs) and their corresponding 95% confidence intervals (CIs) for main cancer sites were calculated using two approaches of unweighted ratio and random effect model. The heterogeneity and its sources of the results were examined with a Q-statistic and Z-score test. The dose-response effect as reflected in the percentage of all deaths due to mesothelioma served as a proxy measure of chrysotile exposure. Results A cohort of twenty six workers exposed to chrysotile alone was summarized. The significantly elevated meta-SMRs for all deaths (1.27), all cancers (1.28), cancers of respiratory organs (2.51), cancers of lung (2.35) and cancers of stomach (1.24) were observed. The significantly elevated meta-SMRs for lung cancer within occupational strata were observed among textile workers (3.55), asbestos product manufacturers (3.30), miners and millers (2.24), cement product workers (1.22), and for stomach cancer among asbestos product manufacturers (1.49). Meta-SMRs for cancers at other sites were not significant. Meta-SMR for lung cancer showed an increasing trend with an elevated percentage of all deaths from mesothelioma, but no such trend for stomach cancer. Conclusion There are excessive risks of lung cancer and mesothelioma among workers exposed to chrysotile fiber alone, and likely no convincing indication of an etiological association between chrysotile exposure and cancers at other sites.

    An epidemiologic and clinical study of neck and upper limb musculoskeletal disorders was carried out on 65 vibration-exposed forestry operators using chain-saws and 31 comparable control subjects (maintenance workers) performing manual activity and not exposed to vibration. Upper limb function was evaluated by measuring finger and wrist circumference size, maximal hand grip strength and range of motion manoeuvres in both the controls and the exposed workers. Vibration from two chain-saws was measured, and vibration exposure for each forestry worker was assessed in terms of 4 h energy-equivalent frequency-weighted acceleration according to ISO 5349. Job analysis indicated a slight excess risk of upper extremity cumulative trauma disorders (CTDs) in the forestry operators compared with the control workers. After adjustment for age and body constitution, significantly higher prevalence rates of persistent upper limb pain, muscle-tendon syndromes and carpal tunnel syndrome were observed among the forestry workers than among the controls. In the forestry operators, the occurrence of upper limb musculoskeletal disorders increased with increasing vibration exposure. Upper limb function was found to be impaired in the forestry workers compared with the controls. Vibration exposure was significantly related to increased finger circumference size, diminished muscle force and reduced joint function. Even though it is difficult to establish the relative importance of vibration and ergonomic factors in the aetiology of CTDs, nevertheless the results of this study indicate that musculoskeletal impairment to the upper limbs was more severe in the forestry operators than in the controls who did solely manual work. This finding and the observed dose-effect relationships suggest that vibration stress is an important contributor to the development of musculoskeletal disorders in workers using hand-held vibrating tools.

    Full Text Available Introduction: Ionizing radiation induces various kinds of DNA damage in which may lead to chromosomal aberrations (CA. Inspite of growing importance in the risk assessment, the dose yield kinetics of CA and their implications for dose assessment are not well established in exposures to low level radiation. In the present study, cytochalasin-B blocked micronucleus assay and metaphase analysis were used as test system to monitor hospital radiation workers who received chronic low dose ionizing radiation below dose limit. Materials and Methods: Heparinized blood samples were taken from healthy non-smoker radiology and radiotherapy workers occupationally exposed to X and gamma rays and healty population whose duties do not expose them to radiation sources and chemical agents. The whole body dose was measured by film badge. Lymphocytes were cultured in RPMI-1640 supplemented with 15% FBS, and metaphase spread was prepared using standard cytogenetic method. Cytochalasine-B (3 mg/mltreatment was used for binuclei micronuclei assay. 100 mitoses and 1000 binuclei lymphocytes were scored for CA and micronuclei (MN respectively. Results: Results show a high frequency of CA mainly deletions and simple breaks in radiation workers compared to control (p<0.001. Also results show the mean MN/cell was significantly (p<0.001 higher in radiation workers(0.035 when compared to non exposed individuals(0.022. Conclusion: A relatively high frequency of MN and CA formation in lymphocytes of radiation workers compared to non exposed individuals might be due to an accumulation of initial DNA damage in people exposed to chronic doses of radiation leading to detectable genetic damages. These observations might imply that the current occupational exposure levels might be inadequate to prevent an increase in chromosome damage rate.

    Full Text Available Introduction & Objective: Benzene is a light yellow liquid with aromatic odor and has effects to human body. The main and dangerous health effect of chronic exposure to benzene in workplace is hematopoetic system disease or blood cancer that it's primarily clinical figures are anemia, leucopenia, thrombocytopenia. The objective of this study was evaluation of benzene exposure by analysis of urinary trans, trans-muconic acid (t,t-ma in post shift of workers.Materials & Methods: A case-control study was conducted. The urine samples were collected from 42 workers exposed to benzene at a cokery plant and it’s by –product refinery site and 40 non exposed villagers from rural areas without nearby factories. The t,t-ma was extracted from urine by solid phase extraction (SPE and analyzed via high performance liquid chromatography (HPLC. The urinary creatinine level was measured by Kone – Pro autoanalyzer . Results: The mean urinary t,t – ma level was 3.33 mg/g creatinine for exposed workers and 0.1007 mg/g creatinine for non exposed workers. The urinary levels in exposed group differed among workplaces, and were higher for subjects that worked in cokery plant ( cokery plant, 3.68 mg / g creatinine; its by product refinery site, 0.64 mg / g creatinine.Conclusion: The results showed that the mean level of urinary t,t-ma was about 6 to 7 times more than biological exposure index; thus, there is a high risk of hematopoetic damage and other adverse effects in these workers. We suggest that the company must decrease benzene exposure via engineering and management controls to lower than threshold limit value.

    This multi-centered study was designed to evaluate the biological effects of exposure to antineoplastic drugs (ADs) at PIVAS (Pharmacy Intravenous Admixture Service) across ten Chinese hospitals. 8-hydroxy-2-deoxyguanosine (8-OHdG) was used as a biomarker of DNA oxidative damage and lymphocyte apoptosis assays using peripheral lymphocyte cells were used to detect primary DNA damage. The mutagenicity activity was estimated with the Ames fluctuation test. 158 exposed and 143 unexposed workers participated in this study. The urinary 8-OHdG/Cr concentrations of the exposed group was 22.05±17.89ng/mg Cr, which was significantly higher than controls of 17.36±13.50ng/mg Cr (P<0.05). The rate of early lymphocyte apoptosis was slightly increased in exposed group than that of the control group (P=0.087). The mutagenic activity was significantly higher in the exposed group relative to the control group (P<0.05). Moreover, while no statistically significant difference was observed, higher concentrations of 8-OHdG/Cr in urine and an early lymphocyte apoptosis rate were found in exposed group II as compared to exposed group I. In addition, a significant correlation between early lymphocyte apoptosis and exposure time to ADs was also observed (P<0.05). In conclusion, our study identified elevated biomarkers in PIVAS workers exposed to ADs. However whether these findings could lead to increased incidence of genotoxic responses remains to be further investigated. PMID:27179702

  2. Flow injection determination of lead and cadmium in hair samples from workers exposed to welding fumes

    International Nuclear Information System (INIS)

    A flow injection procedure involving continuous acid leaching for lead and cadmium determination in hair samples of persons in permanent contact with a polluted workplace environment by flame atomic absorption spectrometry is proposed. Variables such as sonication time, nature and concentration of the acid solution used as leaching solution, leaching temperature, flow-rate of the continuous manifold, leaching solution volume and hair particle size were simultaneously studied by applying a Plackett-Burman design approach. Results showed that nitric acid concentration (leaching solution), leaching temperature and sonication time were statistically significant variables (confidence interval of 95%). These last two variables were finally optimised by using a central composite design. The proposed procedure allowed the determination of cadmium and lead with limits of detection 0.1 and 1.0 μg g-1, respectively. The accuracy of the developed procedure was evaluated by the analysis of a certified reference material (CRM 397, human hair, from the BCR). The proposed method was applied with satisfactory results to the determination of Cd and Pb in human hair samples of workers exposed to welding fumes

    1982-01-01

    Lead-exposed (n . 26) and control (n . 12) subjects were investigated for their blood lead concentration erythrocyte 5-amino-laevulinic acid dehydratase (5-ALAD) and erythrocyte uroporphyrinogen-I-synthetase (URO-I-S) activity; 5-amino-laevulinic acid (5-ALA) and porphobilinogen (PBG) were used as substrates in the synthetase assay. In the lead workers erythrocyte 5-ALA dehydratase was grossly inhibited but with PBG as substrate the synthetase activity was not significantly different from the control group. With 5-ALA as substrate the synthetase assay showed marked inhibition. Addition of zinc (0.1 mmol/l) and dithiotheritol (0.5 mmol/l) brought the activities of both the dehydratase and synthetase (using 5-ALA as substrate) back into the ranges seen in the control group. With porphobilinogen as substrate higher concentrations of zinc caused inhibition of the synthetase, whilst reduction of added zinc to 0.01 mmol/l resulted in stimulation of the synthetase. A good correlation (r . 0.87) was obtained in synthetase assay when PBG and 5-aminolaevulinate (with added zinc and dithiothreitol) were used as substrates. With these additions 5-ALA may be used as a substrate in the URO-I-S assay in the investigation of latent cases of acute intermittent porphyria.

    The purpose of this article is to analyze the results of a 10-year survey of the radiation effects of some immune parameters of occupationally exposed personnel from the Nuclear Power Plant “Kozloduy”, Bulgaria. 438 persons working in NPP with cumulative doses between 0.06 mSv and 766.36mSv and a control group with 65 persons were studied. Flow cytometry measurements of T, B, natural killer (NK) and natural killer T (NKT) cell lymphocyte populations were performed. Data were interpreted with regard to cumulative doses, length of service and age. The average values of the studied parameters of cellular immunity were in the reference range relative to age and for most of the workers were not significantly different from the control values. Low doses of ionizing radiation showed some trends of change in the number of CD3+CD4+ helper-inducer lymphocytes, CD3+ CD8+ and NKT cell counts. The observed changes in some of the studied parameters could be interpreted in terms of adaptation processes at low doses. At doses above 100–200 mSv, compensatory mechanisms might be involved to balance deviations in lymphocyte subsets. The observed variations in some cases could not be attributed only to the radiation exposure because of the impact of a number of other exogenous and endogenous factors on the immune system.

    Full Text Available The burden of exposure to blood-borne pathogens (such as hepatitis B and C viruses is considerable for health care workers. Hepatitis virus transmission requires a non-immune host, an infectious source, and skin or mucous membrane injury. These three aspects are the main fields for preventional interventions. We reviewed major recent studies on this topic to identify precautions health care workers should take to avoid hepatitis B (HBV and C virus (HCV infections. Accordingly, this review looks at aspects of epidemiology, risk factors, economy, knowledge, attitudes, practice, and ethics of HBV and HCV that affect health care workers. The risk of transmission depends on the load of pathogen, infectious characteristics and exposure frequency. Health care workers skill levels and the specific hospital department involved appear to be the most important factors in the exposure of health care workers to blood-borne pathogens. However, many health care workers surveyed, believed that educational programs about standard precautions in their setting were not adequate. Obviously, more detailed studies will be needed to clarify risks and opportunities for health care workers precautions aimed at avoiding HBV and HCV infection, especially in emerging health research communities.

    Full Text Available Abstract Background HIV is an important factor affecting healthcare workforce capacity in high-prevalence countries, such as Swaziland. It contributes to loss of valuable healthcare providers directly through death and absenteeism and indirectly by affecting family members, increasing work volume and decreasing performance. This study explored perceived barriers to accessing HIV/AIDS care and prevention services among health workers in Swaziland. We asked health workers about their views on how HIV affects Swaziland's health workforce and what barriers and strategies health workers have for addressing HIV and using healthcare treatment facilities. Methods Thirty-four semi-structured, in-depth interviews, including a limited set of quantitative questions, were conducted among health workers at health facilities representing the mixture of facility type, level and location found in the Swaziland health system. Data were collected by a team of Swazi nurses who had received training in research methods. Study sites were selected using a purposive sampling method while health workers were sampled conveniently with attention to representing a mixture of different cadres. Data were analyzed using Nvivo qualitative analysis software and Excel. Results Health workers reported that HIV had a range of negative impacts on their colleagues and identified HIV testing and care as one of the most important services to offer health workers. They overwhelmingly wanted to know their own HIV status. However, they also indicated that in general, health workers were reluctant to access testing or care as they feared stigmatization by patients and colleagues and breaches of confidentiality. They described a self-stigmatization related to a professional need to maintain a HIV-free status, contrasting with the HIV-vulnerable general population. Breaching of this boundary included feelings of professional embarrassment and fear of colleagues' and patients' judgements

    Full Text Available This study focused on the determination of the delivery of services of day care workers in the municipality of Sta. Maria, Province of Laguna during the first semester of school year 2012-2013. Descriptive research was used in this study. Among the key findings were that Day Care Workers with respect to interactional relationship accomplished the functions with outstanding adequacy such as constantly giving feedback and praises on the performance of children, along with workers and parents coordination and cooperation, with verbal interpretation of Always Observe. In terms of instructional quality both group of respondents perceived that day care workers in-charge had adequate abilities and competencies concerning their education and trainings in connection with teaching small children with verbal interpretation of Always Observe. The parents had confidence to the day care workers in-charge of their children aside from regularly consulting the day care workers about their children’s progress with verbal interpretation of Always Observe. There were only 871 households who availed of the services of day care centers in which 27 workers were employed and each of them assigned to handle an average of 33 children. Notable along with other findings was the day care workers and parents had the same perception as to the extent of services provided by the Day Care Center with respect to interactional relationship, instructional quality and parental participation. Subsequently the study ensued with these five factual remarks: Children’s interactions with parents in the centers were the direct mechanisms through which children learn. The educational qualification and the capability of the day care workers to handle small children were the primary essentials in children’s learning. Parents’ participation in the day care centers premises brought harmonious relationship between the Day Care Workers and children as well. The capacity of day care worker

    Full Text Available Objectives: The aim of this study is to assess chromosomal damage in Tunisian hospital workers occupationally exposed to low levels of ionizing radiation (IR. Materials and Methods: The cytokinesis-block micronucleus (CBMN assay in the peripheral lymphocytes of 67 exposed workers compared to 43 controls matched for gender, age and smoking habits was used. The clastogenic/aneugenic effect of IR was evaluated using the CBMN assay in combination with fluorescence in situ hybridization with human pan-centromeric DNA in all the exposed subjects and controls. Results: The study showed a signifi cant increase of the micronucleus (MN frequency in the lymphocytes of the exposed workers compared to the control group (13.63±4.9‰ vs. 6.52±4.21‰, p < 0.05. The centromere analysis performed in our study showed that MNs in hospital staff were predominantly centromere negative (72% and the mean negative labeled micronucleus (C–MN frequency was signifi cantly higher in the exposed subjects than in the controls (9.04±4.57‰ vs. 1.17±0.77‰. The multivariate regression analysis, taking into account all confounding factors, showed that only the time of exposure to IR had a signifi cant effect on the level of MNs and C–MN. Conclusion: The present study shows that chromosomal damage leading to the formation of micronucleated lymphocytes is more frequent in the hospital workers exposed to IR than in the controls, despite the low levels of exposure. The results of the study confi rm the well-known clastogenic properties of ionizing radiation. In regards to health monitoring, detection of early genotoxic effects may allow for the adoption of preventive biological control measures, such as hygienic improvements in the workplace or reduction of hours of occupational exposure.

    Full Text Available Our mutagenesis group has been studying with important economic drivers of our state, such as agriculture, the footwear and leather industry and open-cast coal mining. Working conditions in these sectors have potentially harmful to humans. The aim of these studies is to determine the health risk of workers by biomonitoring subjects exposed to genotoxic agents. The main results of our studies with vineyard farmers we observed a high rate of MN and DNA damage in individuals exposed to pesticides (p < 0.001. In addition, some effects of genetic polymorphisms in the modulation of MN results were observed in this group. Tobacco farmers were also evaluated at different crop times. The results showed a significant increase in the Damage index and frequency in tobacco farmers compared to the non-exposed group, for all crop times. The results for footwear and tannery workers showed a significant increase in the mean ID for the solvent-based adhesive (p < 0.001 group in comparison to the water-based adhesive group and control (p < 0.05. For open-cast coal mine workers, the EBCyt indicated a significant increase in nuclear bud frequency and cytokinetic defects in the exposed group compared to the non-exposed group (p < 0.0001. We were able to associate specific genetic susceptibility with each type of exposure and with the non-use or improper use of personal protection equipment and diet adequacy. These results show how important the continuous education of exposed workers is to minimizing the effect of the occupational exposure and the risk of disease associated with the work.

    Health care workers are among the high-risk populations for hepatitis B virus (HBV) infection as they have more opportunities exposing to blood or other body fluids from HBV infected patients.The main routes of HBV infection are needle sticks or sharp injuries for health care workers.Vaccination is the most effective measure to prevent HBV infection in this population.The prevalence of HBsAg varies because of different immunization strategies and vaccination coverage rates of health care workers in different regions.In Europe such as France,all of the health care workers except housekeeping and supporting staff must be vaccinated compulsorily and the vaccination coverage rate reached up to 97.0%,which resulted in a quick decrease in HBV infection.In America such as United States,each medical facility is required to provide hepatitis B vaccine free for its health care workers.In 2006,the vaccination coverage rate in USA was 90.0%,and HBV infection rate (1.0× 10-4) was lower than that in general population (5.0 × 10-4).In East Mediterranean countries such as Pakistan,the vaccination coverage rate in health care workers was 73.4% but no immunization strategy for them was found.The relatively high vaccination coverage rate decreased the rate of HBsAg carrier to 0.6%-2.2%,lower than that in the regular population (6.0%).In Africa such as Uganda,only 6.2% of health care workers had history of HBV vaccination,and HBsAg carrier rate was as high as 9.0%.Uganda is currently drafting hepatitis B vaccination strategies for health care workers.In Western Pacific area such as Hong Kong and Taiwan of China,the vaccination coverage rates in health care workers were 85.0% and 73.7 % respectively,but the vaccination strategies were unclear.In 2009,we investigated the HBV infection status in 3 126 health care workers in Jilin province of China,and the positive rates of HBsAg and antiHBc were 1.4% and 33.4%,respectively,which were lower than that in common

  12. Study of occupational health impact of atmospheric pollution on exposed workers at an iron and steel complex by using neutron activation analysis of scalp hair

    International Nuclear Information System (INIS)

    The occupational health impact of atmospheric pollution on exposed workers at one iron and steel complex was studied by instrumental neutron activation analysis of workers' hair samples and medical examination. The experimental results indicate that there is a positive correlation between the high inhalation amounts of iron and other trace elements by the exposed workers and the symptom of their high blood pressure and hypoglycemia, which implies that the atmospheric environment polluted by iron and steel industry has an adverse health impact on the exposed workers. The measures to relieve and abate the occupational diseases caused by air-borne particulate matter should be taken. (author)

  13. Sickness absence from 1978 to 1992 of Electricite de France (EDF) workers exposed to ELF-EMF: the substation group

    International Nuclear Information System (INIS)

    Electromagnetic fields are suspected of many health effects, including cancers, immunity and fertility disorders, congenital malformations, suicides and depression.... Although the results of all studies are contradictory and no biological mechanism has been found, populations are concerned about this matter. This study analyzes the absence from work of some EDF employees who are a priori the most professionally exposed to ELF EMF. Absence from work is taken as an health indicator. Although it is not specific, it can be predictive of serious health problems. The specific context of EDF has made it possible to collect and analyze the medical aspect of absence from work, that is rare in France. We were interested with employees working with high voltage (over 90 kV). Three job categories have been selected: live line workers, substation maintenance workers and substation exploitation workers (called in the company the ATEX). The first group concerned the live linemen and the results were exposed previously. It appeared they had more accidents at work, but this was more related to the job of lineman rather than to the EMF exposure. Nevertheless, substation workers have an exposure less intensive but longer than live linemen. We present here the result about the absenteeism of the substation workers, maintenance and exploitation. (author)

    1991-01-01

    There is no logical, linear way to approach a future in which knowledge and technology explode and new opportunities go hand-in-hand with rapid obsolescence. Teams and task groups will replace the vertical command structures of the past, making teamwork, flexibility, and imagination more important that absolute knowledge. Maximum downward task delegation and decentralization will empower workers at all levels while challenging the assumptions of licensure. As the health-care organization grows more ephemeral, management will become an increasingly subtle art. Visionary skills are essential in a dynamic, rapidly changing society where the past is no longer a guide for the future. PMID:1958819

  16. Left ventricular diastolic function in workers occupationally exposed to mercury vapour without clinical presentation of cardiac involvement

    International Nuclear Information System (INIS)

    The aim of the study was to evaluate left ventricular diastolic function in workers occupationally exposed to mercury vapour without clinical presentation of cardiac involvement. The studies included 115 workers (92 men and 23 women) occupationally exposed to mercury vapour without clinical presentation of cardiac involvement (mean age: 47.83 ± 8.29). Blood samples were taken to determine blood lipid profile, urine was collected to estimate mercury concentration (Hg-U) and echocardiographic examination was performed to evaluate diastolic function of the left ventricle. In the entire group of workers occupationally exposed to mercury vapour without clinical presentation of cardiac involvement, Spearman correlations analysis demonstrated the following significant linear relationships: between body mass index (BMI) and ratio of maximal early diastolic mitral flow velocity/early diastolic mitral annular velocity (E/E') (r = 0.32, p Hg-U = 1.071, ORBMI = 1.200, ORHDL = 0.896, p < 0.05). Summing up, occupational exposure to mercury vapour may be linked to impaired left ventricular diastolic function in workers without clinical presentation of cardiac involvement. -- Highlights: ► Study aimed at evaluation of LVDD in workers occupationally exposed to Hg. ► There was significant linear relationships between Hg-U and E/E'. ► Independent risk factor of LVDD in study group included higher Hg-U. ► Independent risk factor of LVDD in study group included higher BMI and lower HDL. ► Occupational exposure to Hg may be linked to LVDD.

  17. Beta-carotene reduces oxidative stress, improves glutathione metabolism and modifies antioxidant defense systems in lead-exposed workers

    International Nuclear Information System (INIS)

    The aim of this study was to determine whether beta-carotene administration reduces oxidative stress and influences antioxidant, mainly glutathione-related, defense systems in workers chronically exposed to lead. The population consisted of two randomly divided groups of healthy male volunteers exposed to lead. Workers in the first group (reference group) were not administered any antioxidants, while workers in the second group (CAR group) were treated orally with 10 mg of beta-carotene once a day for 12 weeks. Biochemical analysis included measuring markers of lead-exposure and oxidative stress in addition to the levels and activities of selected antioxidants. After treatment, levels of malondialdehyde, lipid hydroperoxides and lipofuscin significantly decreased compared with the reference group. However, the level of glutathione significantly increased compared with the baseline. Treatment with beta-carotene also resulted in significantly decreased glutathione peroxidase activity compared with the reference group, while the activities of other glutathione-related enzymes and of superoxide dismutase were not significantly changed. However, the activities of glucose-6-phosphate dehydrogenase and catalase, as well as the level of alpha-tocopherol, were significantly higher after treatment compared with the baseline. Despite controversy over the antioxidant properties of beta-carotene in vivo, our findings showed reduced oxidative stress after beta-carotene supplementation in chronic lead poisoning. - Highlights: • Beta-carotene reduces oxidative stress in lead-exposed workers. • Beta-carotene elevates glutathione level in lead-exposed workers. • Beta-carotene administration could be beneficial in lead poisoning

    The aim of this study was to determine whether beta-carotene administration reduces oxidative stress and influences antioxidant, mainly glutathione-related, defense systems in workers chronically exposed to lead. The population consisted of two randomly divided groups of healthy male volunteers exposed to lead. Workers in the first group (reference group) were not administered any antioxidants, while workers in the second group (CAR group) were treated orally with 10 mg of beta-carotene once a day for 12 weeks. Biochemical analysis included measuring markers of lead-exposure and oxidative stress in addition to the levels and activities of selected antioxidants. After treatment, levels of malondialdehyde, lipid hydroperoxides and lipofuscin significantly decreased compared with the reference group. However, the level of glutathione significantly increased compared with the baseline. Treatment with beta-carotene also resulted in significantly decreased glutathione peroxidase activity compared with the reference group, while the activities of other glutathione-related enzymes and of superoxide dismutase were not significantly changed. However, the activities of glucose-6-phosphate dehydrogenase and catalase, as well as the level of alpha-tocopherol, were significantly higher after treatment compared with the baseline. Despite controversy over the antioxidant properties of beta-carotene in vivo, our findings showed reduced oxidative stress after beta-carotene supplementation in chronic lead poisoning. - Highlights: • Beta-carotene reduces oxidative stress in lead-exposed workers. • Beta-carotene elevates glutathione level in lead-exposed workers. • Beta-carotene administration could be beneficial in lead poisoning.

    Full Text Available The study analyzed the exposure factors that may lead to neuropsychological symptoms among 92 workers who were exposed to xylene and toluene and 100 workers who were not exposed to the solvents. The airborne concentration of xylene and toluene was evaluated with personal passive badges. The levels of methyl hippuric acid and hippuric acid in urine were assessed, and interviews were performed to observe the neuropsychological symptoms that may result from exposure to the solvents. The result showed that the average concentration for the exposed group of xylene in the paint company working environment was 2.7 (SD = 2.4 ppm and the average concentration of toluene was 9.5 (SD = 10.4 ppm. The average level of methyl hippuric acid in urine was 78 (SD = 74.7 mg/g creatinine. Factors that affected the neuropsychological symptoms included the following. (1 The impact of age: the risk (adjusted odds ratio for getting psychosomatic symptoms in persons over 40 and exposed to xylene was 9.5 and the aOR of those exposed to toluene was 8.3. (2 The impact of not providing personal protective equipment was found to be sleep disturbance; it was found that the aOR of those exposed to xylene was 3.9, and the aOR of those exposed to toluene was 4.4. In summary, periodic examination of workers by occupational physician is needed for detection of early neuropsychological effects, especially psychosomatic symptoms, and sleep disturbances.

    Niche markets such as Medicare, Medicaid and behavioral healthcare are looking to managed care to control costs and increase the quality of care provided. Now workers' compensation officials are looking to managed care with the same goals in mind. As managed care organizations begin marketing to these special populations, the information glut is growing. Information technology can aid managed care officials in the collection, organization and dissemination of the data. PMID:10177514

    Microaneurysms are important in the diagnosis of vascular changes caused by carbon disulfide. They can be diagnosed by ophtholmoscopy, angiography or angioscopy. In our opinion even a careful ophthalmoscopic investigation is sufficient for diagnosis, so that angiography is not absolutely necessary for any mass survey. The incidence of microaneurysms correlates with the duration (both daily and total) as well as with the intensity of exposure to carbon disulfide. The quantity correlates closely with the intensity of exposure. The incidence of microaneurysms is not correlated to age; however it was found to be highest in 40-50-year-old men working with staple fibers, whereas in the spinning department it occurred in 50-55-old men. Microaneurysms are found equally frequently in active workers and invalids. There was no difference between the two groups with regard to degenerative changes of the macula. However, the changes found in the eyes of men from the staple fiber department were more pronounced than in those from the spinning department.

    Informal payments for health services are common in many transitional and developing countries. The aim of this paper is to investigate the nature of informal payments in the health sector of Tanzania and to identify mechanisms through which informal payments may affect the quality of health care. Our focus is on the effect of informal payments on health worker behaviours, in particular the interpersonal dynamics among health workers at their workplaces. We organised eight focus groups with 58 health workers representing different cadres and levels of care in one rural and one urban district in Tanzania. We found that health workers at all levels receive informal payments in a number of different contexts. Health workers sometimes share the payments received, but only partially, and more rarely within the cadre than across cadres. Our findings indicate that health workers are involved in 'rent-seeking' activities, such as creating artificial shortages and deliberately lowering the quality of service, in order to extract extra payments from patients or to bargain for a higher share of the payments received by their colleagues. The discussions revealed that many health workers think that the distribution of informal payments is grossly unfair. The findings suggest that informal payments can impact negatively on the quality of health care through rent-seeking behaviours and through frustrations created by the unfair allocation of payments. Interestingly, the presence of corruption may also induce non-corrupt workers to reduce the quality of care. Positive impacts can occur because informal payments may induce health workers to increase their efforts, and maybe more so if there is competition among health workers about receiving the payments. Moreover, informal payments add to health workers' incomes and might thus contribute to retention of health workers within the health sector. PMID:20709420

    Utilizing a self-administered questionnaire in 440 health care workers (81% response rate), we evaluated the impact of health care workers policy awareness on hand hygiene and urinary catheter care in nursing homes. We show that health care workers aware of their nursing home policies are more likely to report wearing gloves and practicing hand hygiene as per evidence-based recommendations during urinary catheter care compared with those who are unaware of their facility policies.

  5. Evaluating the genotoxic effects of workers exposed to lead using micronucleus assay, comet assay and TCR gene mutation test

    International Nuclear Information System (INIS)

    To evaluate the genotoxic effects of lead (Pb) exposure, 25 workers in a workplace producing storage battery were monitored for three genetic end-points using micronucleus (MN) assay, comet assay and TCR gene mutation test. Twenty-five controls were matched with workers according to age, gender and smoking. The air Pb concentration in the workplace was 1.26 mg/m3. All subjects were measured for Pb concentration of blood by atom absorption spectrophotometry. The mean Pb concentration of blood in workers (0.32 mg/l) was significantly higher than that in controls (0.02 mg/l). The results of MN test showed that the mean micronuclei rate (MNR) and mean micronucleated cells rate (MCR) in workers were 9.04 ± 1.51 per mille and 7.76 ± 1.23 per mille , respectively, which were significantly higher than those (2.36 ± 0.42 per mille and 1.92 ± 0.31 per mille ) in controls (P -4 and 1.74 ± 0.17 x 10-4, respectively, there was no significant difference between workers and controls (P > 0.05). The results of our study indicated that the genetic damage was detectable in 25 workers occupationally exposed to lead

    The production process of abrasives use aluminium, or silicon carbide a synthetic material with a hardness only slightly less than that of a diamond. It is popularly known as carborundum since it was first manufactured as an abrasive in 1891, produced by the fusion of high grade silica and petroleum coke with sawdust. For many years silicon carbide was thought not to give rise to pulmonary lesions. Recently several researchers suggested the existence of a carborundum pneumoconiosis. The aim of this study was to evaluate the role of the pulmonary clearance of {sup 99m} Technetium chelated to diethylene-triamine penta-acetate ({sup 99m} Tc DTPA), and {sup 67} Gallium lung scanning in workers exposed to abrasive dusts. Thirty seven subjects, 13 smokers and 24 nonsmokers and ex smokers were studied. In 32 (86,48%) {sup 67} Gallium lung scanning was positive including 13 (40,62%) retired workers. We conclude that non smoking workers of abrasives plants have a pulmonary alveolar epithelial permeability disturbance similar as observed in smoking workers and smoking controls. Most workers, ex-workers of these industries and in patients with carborundum pneumoconiosis there is an evidence of pulmonary inflammation measured with abnormal {sup 67} Gallium lung scan.

    Forty shoe factory workers who were exposed to hexane were investigated to see if there was a correlation between electroneuromyographic changes indicative of neuropathy and urinary excretion of 2,5-hexanedione. Urinary samples were analyzed for the presence of the metabolic products of n-hexane and its isomers. Electrodiagnostic examination was carried out following the urinary sampling. A rating scale was used to obtain a cumulative numeric index of electrodiagnostic findings. 2,5-Hexanedione and ..gamma..-valerolactone were discovered in all cases, while 2-hexanol was found in 11 cases. 2,5-Hexanedione was the main metabolite in most cases (39 of 40). Only in 1 case was a low level of 2-methyl-2-pentanol detected; 3-methyl-2-pentanol was never detected. Metabolic products of cyclohexane were present in about one-fifth of the cases, while trichloroethanol, a metabolic product of trichloroethylene, was nearly always present, all at very low concentrations. Electromyographic abnormalities significant for early detection of toxic polyneuropathy were found in 14 cases. A statistically significant correlation of the electroneuromyographic scoring on the urinary concentrations of measured metabolites was observed only with 2,5-hexanedione and ..gamma..-valerolactone, both derived from n-hexane. Since ..gamma..-valerolactone is probably not a true metabolite of n-hexane, the authors results support the hypothesis that polyneuropathies in shoemakers are due to 2,5-hexanedione. For practical purposes the urinary concentration of 2,5-hexanedione can serve as a predictive measurement for early detection of neurotoxic lesions at preclinical states.

    2010-04-01

    This article highlights the Farm Worker Family Health Program's (FWFHP) strategies for providing care to migrant farm workers residing within a unique social and cultural context. The care provided by health professions students from a variety of disciplines extends and augments the work of the local migrant farm worker clinic that is pushed beyond capacity during peak growing and harvest times. Nursing's social responsibility to care for underserved populations is a guiding principle of the FWFHP and shapes how the work is translated into action. The FWFHP is a community-academic partnership that began in the rural southeastern United States in 1993. Challenges facing migrant farm worker families include access to health care, language, health literacy, housing and sanitation, family and community integrity, and workplace safety. The nursing practice strategies used to address these health challenges may be adapted to strengthen health programs serving other populations who live in poverty or reside in low-resource settings.

  9. Proposal and application of methodology for monitoring workers occupationally exposed to Thorium-232 and its decay products

    International Nuclear Information System (INIS)

    Thorium-232 is the parent of one of the naturally occurring decay series and is widely spread on the earth's crust, being also present in higher concentrations at some deposits located mainly in Brazil and India. The occupational exposure to this radionuclide may occur in several steps of the thorium cycle. In Brazil, there is a large number of workers that should be monitored because they manipulate directly or indirectly different kinds of ores, raw materials and products containing significant amounts of thorium in its composition. In this study, the techniques developed specifically for the in vivo and in vitro monitoring of these workers are presented together with the application of these techniques to a group of selected workers classified as occupationally exposed. It is also presented the methodology by which the results obtained with these measurements are interpreted with the objective of identifying the main pathways of incorporation and reducing the internal doses to values as low as reasonably achievable.

  1. Determination of eye lens doses and identification of risk groups among radiation exposed workers. An Austrian pilot study

    International Nuclear Information System (INIS)

    On European level, in 2014 the dose limit for the lens of the eye of radiation exposed workers has been reduced from 150 to 20 mSv per year (2013/59/Euratom). Data about eye lens exposition measured under realistic operational conditions of Austrian radiation exposed workers is sparse and there is no information to verify, if all professional groups identified to be at risk for elevated eye doses will remain below the new annual dose limit. Therefore, financed by the Austrian Workers Compensation Board, AUVA, a pilot study has been initiated to answer this question. Based on published information professional groups of radiation exposed workers and operational tasks with an enhanced risk of elevated eye lens doses have been identified. By dosimetric measurements with volunteers (forehead dose meters and parallel measurements with whole-body TL-dose meters above and under the lead apron) realistic lens doses will be estimated during selected radiation exposed tasks. Comparison of yielded doses will show whether a TLD outside the apron could serve as an alternative to forehead dose meters dedicated to measure eye lens doses. Measurements with leaded protective eyewear based on IEC61331 yield results for lead equivalent in good agreement with manufacturers' information. Results for eye lens doses determined by use of a RANDO head phantom and a standardized phantom simulating a body in a typical exposition situation for interventional radiologists show that wearing of leaded goggles allows for a 90% dose reduction. Under such conditions the eye lens dose is dominated by backscatter and stray radiation from the operator's head and patient body. This has to be considered for the evaluation of protective effectiveness for leaded eye wear.

    A meeting of the Viral Hepatitis Prevention Board in Barcelona in November 2012 brought together health care professionals concerned with viral hepatitis and those concerned with other vaccine-preventable diseases (especially influenza) in order to share experiences and find ways to increase the protection of health care workers through vaccination. Despite the existence of numerous intergovernmental and national resolutions, recommendations or published guidelines, vaccine uptake rates in health care workers are often shockingly low and campaigns to increase those rates have been generally unsuccessful. Participants reviewed the numerous incentives and barriers to vaccine uptake. Reasons for low uptake range from lack of commitment by senior management of health facilities and unclear policies to lack of knowledge, and denial of risk. Positive factors included leadership, involvement of all concerned parties, reminders and peer pressure. Innovative approaches, including the use of social media, are needed. It was concluded that strategies should be modified appropriately to reach specific health care worker populations at risk and that policies for preventing infection of health care workers could include obligatory health checks to determine vaccination status or immunity. Further, mandatory vaccination of health care workers may be the only effective means in order to achieve high vaccination coverage rates. Suggested possible future activities included: refurbishment of the image of the occupation health profession; resolving the logistical problems of administering vaccine; elaborating policy on managing health care workers who have been vaccinated against hepatitis B at birth or in early childhood and who are now starting to work in the health professions; and embedding and applying policies on vaccination against vaccine-preventable diseases in all health care facilities and training institutions. Above all, national action plans need to be written, with the

    Full Text Available Abstract Background HIV/AIDS is fast becoming a chronic disease with the advent of antiretroviral drugs, therefore making home based care key in the management of chronically ill HIV/AIDS patient. The objective of this study was to determine the perception and practice of health care workers on HIV/AIDS related home based care in the health facilities in Ogun state, Nigeria. Methods This study is an analytical cross-sectional study. A multistage cluster sampling technique was used to obtain a representative sample of the primary health care workers in Ogun state. An interviewer administered structured questionnaire was administered by trained health workers to elicit the required information. Result A total of 350 health care workers were interviewed, 70% of the respondents could adequately describe the components of home based care. Only 38.7% were aware of the National guideline on home based care practices and 17.1% believe that home based care will not significantly improve the prognosis of PLWAs. Few 19.1% had ever been trained or ever involved 16.6% in home based care practices. Only 20 [5.7%] are involved on a weekly basis, 16 [4.6%] monthly and 22 [6.3%] quarterly. Reasons given for non implementation of home based care are inadequate number of healthcare workers 45%, lack of political will 24.4%, lack of implementation by facility managers 14% and inadequate funds 16.6%. Factors that were significantly associated with the practice of home based care were perception of its relevance in improving prognosis [OR = 54.21, C.I = 23.22-129.52] and presence of a support group in the facility [OR = 4.80, C.I = 2.40-9.57]. There was however no statistically significant relationship between adequate knowledge of home based care [OR = 0.78, C.I = 0.39-1.54] and previous training on home based care (OR = 1.43, C.I = 0.66-3.06]. Conclusion The practice of home based care for HIV/AIDS among the study population is low

    Full Text Available As a zoonotic pathogen, Encephalitozoon cuniculi is a cause of serious disease in animals and people. The present study was to evaluate the health status examination of this seropositive animal care worker in our previous study.Blood samples were taken from five workers. CIA test was applied to detect antibodies against E. cuniculi in blood serum. The indirect immunofluorescence antibody test was used as confirmation test. Seropositive worker had a complete medical examination.Only one worker was found to be seropositive according to the results of the serological test. Sera positive to E. cuniculi was confirmed with IFAT and spores were detected in the urine sample of the worker. The worker was treated with albendazole.Rabbits should be examined routinely for the presence of anti-E. cuniculi antibody. People working with laboratory animal should avoid contact with urine and faeces of infected or pay attention to personal hygiene.

    2015-09-01

    With the growth in engineering/technology industries, the United States has seen an increase in the arrival of highly skilled temporary migrant workers on H1B visas from various Asian countries. Limited research exists on how these groups maintain family ties from afar including caring for aging parents. This study explores the experiences and challenges that Asian H1B workers face when providing care from a distance. A total of 21 Chinese/Taiwanese, Korean, and Indian H1B workers participated in in-depth qualitative interviews. Key findings indicate that despite distance, caring relationships still continue through regular communications, financial remittances, and return visits, at the same time creating emotional, psychological, and financial challenges for the workers. Findings highlight the need for further research in understanding how the decline of aging parent's health impacts the migrants' adjustment and health in the United States. PMID:26267591

  11. The influence of β-carotene on homocysteine level and oxidative stress in lead-exposed workers

    Directory of Open Access Journals (Sweden)

    Sławomir Kasperczyk

    2014-06-01

    Full Text Available Background: Oxidative stress is involved in lead toxicity. This suggests that some antioxidants may play a role in the treatment of lead poisoning. In the light of this, the aim of the study was to determine whether β-carotene administration reduces oxidative stress and homocysteine level in workers chronically exposed to lead. Material and Methods: The exposed population included healthy male workers exposed to lead who were randomly divided into 2 groups (mean blood lead level ca. 44 μg/dl. Workers in the 1st group (N = 49, reference group had no antioxidants, drugs, vitamins or dietary supplements administered, while workers in the 2nd group (N = 33 had β-carotene administered in a dose of 10 mg per day for 12 weeks. Biochemical analysis included markers of lead-exposure and the level of malondialdehyde (MDA, an oxidative stress biomarker. We also measured the level of homocysteine (Hcy and thiol groups as well as the activity of superoxide dismutase (SOD and its isoenzyme EC-SOD in serum. Results: After supplementation, the level of MDA significantly decreased, compared to baseline, by 16%, and to the reference group. When compared to the reference group, Hcy level was also significantly decreased. However, the level of thiol groups was significantly higher after supplementation with β-carotene compared to the reference group. Analogically, the activity of SOD and EC-SOD was significantly higher compared to the baseline and to the reference group. Conclusions: Despite some controversies over antioxidant properties of β-carotene, our results indicate that its antioxidant action could provide some beneficial effects in lead poisoning independent of chelation.

    2012-01-01

    Full Text Available The alkaline single cell gel electrophoresis (comet assay was applied to study the genotoxic properties of silica in human peripheral blood lymphocytes (PBL. The study was designed to evaluate the DNA damage of lymphocytes and the end points like micronuclei from buccal smears in a group of 45 workers, occupationally exposed to silica, from small mines and stone quarries. The results were compared to 20 sex and age matched normal individuals. There was a statistically significant difference in the damage levels between the exposed group and the control groups. The types of damages (type I -type 1V were used to measure the DNA damage. The numbers of micronuclei were higher in the silica-exposed population. The present study suggests that the silica exposure can induce lymphocyte DNA damage and produces significant variation of micronuclei in buccal smear.

  17. Management and processing of dosimetric data of workers exposed to ionizing radiation

    International Nuclear Information System (INIS)

    The Madagascar - INSTN Radiation protection and Dosimetry Department use the reader HARSHAW TLD 6600 for workers doses reading. Although the performance of this device, manual works is required to store and to maintain the dosimetric data after reading and to note the TLDs sent to the establishments. To avoid these manual works, this present work proposes computer programs written in Python and using SQLite software. One of the programs in python retrieves dose values after reading and transfers directly these doses in the workers database. The use of SQLite software provides a way for the dosimetric data management and the TLDs movement monitoring. The other program assesses estimation of the dose received by worker through a trend curve for workers dosimetric monitoring. The calculated differences of this curve over the curve connecting all points are less than 20%, acceptable limit in radiation protection for TLDs. This present work presents then significances for the personnel occupying individual monitoring of ionizing radiation workers and for these workers too.

  2. Evaluation of The Relationship Between Mercury Exposure and Oxidative DNA Lesions in Workers Occupationally Expose to Mercury

    International Nuclear Information System (INIS)

    Evaluation of antioxidant status by measuring the activities of super oxidase dismutase and glutathione peroxidase and the concentrations of total reduced glutathione and protein-bound thiols in the serum, also, measuring urinary 8-hydroxy-2- deoxyguanosine (8-OHdG); which is used as bio marker of oxidative DNA damage in the mercury exposed persons was the objective of this study. The study was carried out on 40 workers exposed to mercury on the job in collaboration with National Institute of Occupational Safety and Health. Samples were collected in December 2008 from workers at fluorescent lamps and dry batteries factories. Urinary 8-hydroxy-2- deoxyguanosine (8-OHdG) was measured used as bio marker of oxidative DNA damage in the mercury exposed persons. The antioxidant status was assessed by measuring the activities of super oxidase dismutase and glutathione peroxidase and the concentrations of total reduced glutathione and protein-bound thiols were also evaluated in the serum. In this study, urinary 8-OHdG which is a metabolite of oxidized DNA was used to evaluate whether mercury exposure led to oxidative damage to DNA. The activities of serum GSH-Px and superoxide dismutase (SOD) and the concentrations of GSH and total protein-boundthiol were also investigated to clarify the relation-ship between body mercury status and oxidative stress. Forty subjects were chosen to participate in this study from workers exposed to mercury on the job. Ten healthy, subjects, matching in age, sex and socio-economic status were chosen as a control group

    2004-01-01

    Tuberculosis (TB) is one of the main public health problems in Sabah; 30% of the total number of TB cases reported in Malaysia every year occur in Sabah. The average incidence of TB among health care workers over the past 5 years is 280.4 per 100,000 population (1, Annual Report of Sabah State TB Control Programme, 1998). At present, there are no specific measures for the prevention of TB transmission in health care facilities. A case-control study was conducted among health care workers in Sabah in 2000-2001. Cases were health care workers with TB diagnosed between January 1990 and June 2000. Controls were health care workers without TB and working in the same facility as cases during the disease episode. The study attempted to identify risk factors for TB among the study population. Data were collected through structured interviews and review of patients' records. The notification rate of TB among health care workers was significantly higher than that to the general population (Z=4.893, pknowledge did not significantly contribute to the risk of contracting TB in this study. However, after controlling for the above factors, age, gender, history of TB contact outside the workplace (other than family contact), duration of service and failure to use respiratory protection when performing high-risk procedures, were the main risk factors of TB among health care workers. This study succeeded in identifying some of the risk factors of TB among health care workers. We managed to include the large ratio of controls to case (3:1) and those cases spanned over a period of 10 years. However, the findings from the study have to be applied with caution due to the limitations of this study, which include recall bias, dropouts, and small sample size. Based on the study findings, we recommend that health care workers in the first 10 years of service should take extra precautions, such as using respiratory protection when performing procedures that are considered to be of high risk

    Benzene, formaldehyde (FA) and trichloroethylene (TCE) are ubiquitous chemicals in workplaces and the general environment. Benzene is an established myeloid leukemogen and probable lymphomagen. FA is classified as a myeloid leukemogen but has not been associated with non-Hodgkin lymphoma (NHL), whereas TCE has been associated with NHL but not myeloid leukemia. Epidemiologic associations between FA and myeloid leukemia, and between benzene, TCE and NHL are, however, still debated. Previously, we showed that these chemicals are associated with hematotoxicity in cross-sectional studies of factory workers in China, which included extensive personal monitoring and biological sample collection. Here, we compare and contrast patterns of hematotoxicity, monosomy 7 in myeloid progenitor cells (MPCs), and B-cell activation biomarkers across these studies to further evaluate possible mechanisms of action and consistency of effects with observed hematologic cancer risks. Workers exposed to benzene or FA, but not TCE, showed declines in cell types derived from MPCs, including granulocytes and platelets. Alterations in lymphoid cell types, including B cells and CD4+ T cells, and B-cell activation markers were apparent in workers exposed to benzene or TCE. Given that alterations in myeloid and lymphoid cell types are associated with hematological malignancies, our data provide biologic insight into the epidemiological evidence linking benzene and FA exposure with myeloid leukemia risk, and TCE and benzene exposure with NHL risk.

  5. The number of workers exposed to ionizing radiation decreased slightly in 2013 in France

    International Nuclear Information System (INIS)

    The number of people monitored for occupational exposure to ionizing radiation reached 352.082 in 2013 in France, it means a slight decrease of 0.7% with respect to 2012 figures. The number of monitored people decreased by 3% in nuclear industry while it increased by 1% in the health sector. The average external radiation dose reached 0.19 mSv, 13.892 workers received a dose greater than 1 mSv and 1894 workers received a dose over 6 mSv. An external annual dose over 20 mSv was recorded for 9 workers. The workers from the non-nuclear industry and the nuclear industry received the highest external doses on the average, respectively 1.62 mSv and 1.27 mSv while the health and research sectors have the lowest mean individual doses: less than 0.6 mSv. Concerning internal exposure, the number of cases of internal contamination remains low: 18 workers received a radiation dose ranging between 1 mSv and 9 mSv in 2013. (A.C.)

    Full Text Available Abstract Background Documentation of test results for latent tuberculosis (TB infection is important for health care workers and students before they begin work. A negative result provides a baseline for comparison with future tests. A positive result affords a potential opportunity for treatment of latent infection when appropriate. We sought to evaluate the yield of the referral process for positive baseline tuberculin tests, among persons beginning health care work or studies. Methods Retrospective cohort study. We reviewed the charts of all new health care students and workers referred to the Montreal Chest Institute in 2006 for positive baseline tuberculin skin tests (≥10 mm. Health care workers and students evaluated for reasons other than positive baseline test results were excluded. Results 630 health care students and workers were evaluated. 546 (87% were foreign-born, and 443 (70% reported previous Bacille Calmette-Guérin (BCG vaccination. 420 (67% were discharged after their first evaluation without further treatment. 210 (33% were recommended treatment for latent TB infection, of whom 165 (79% began it; of these, 115 (70% completed adequate treatment with isoniazid or rifampin. Treatment discontinuation or interruption occurred in a third of treated subjects, and most often reflected loss to follow-up, or abdominal discomfort. No worker or student had active TB. Conclusions Only a small proportion of health care workers and students with positive baseline tuberculin tests were eligible for, and completed treatment for latent TB infection. We discuss recommendations for improving the referral process, so as to better target workers and students who require specialist evaluation and treatment for latent TB infection. Treatment adherence also needs improvement.

    Horevitz, Elizabeth; Manoleas, Peter

    2013-01-01

    The Affordable Care Act has led to a widespread movement to integrate behavioral health services into primary care settings. Integrated behavioral health (IBH) holds promise for treating mild to moderate psychiatric disorders in a manner that more fully addresses the biopsychosocial spectrum of needs of individuals and families in primary care, and for reducing disparities in accessing behavioral health care. For behavioral health practitioners, IBH requires a shift to a brief, outcome-driven, and team-based model of care. Despite the fact that social workers comprise the majority of behavioral health providers in IBH settings, little research has been done to assess the extent to which social workers are prepared for effective practice in fast-paced primary care. We conducted a survey of social workers (N = 84) in IBH settings to assess the following: (1) Key competency areas for social work practice in IBH settings and (2) Self-rated preparedness for effective practice in IBH settings. Online snowball sampling methods were used over a period of 1 month. Results indicate that social workers feel prepared for general practice in IBH settings, but would benefit from additional training in IBH-specific competency areas identified in the survey. Findings can help guide social work training to improve workforce preparedness for practice in IBH settings in the wake of health care reform. PMID:24028739

    Full Text Available Background: Poor care and hygiene of contact lens (CL results in eye problems and infections. Healthcare workers have an important role in advocating correct lens care. Objectives: To determine the practices of CL care and the adverse consequences of poor CL care among healthcare workers. Setting and Design: A cross-sectional study in one public and three private sector hospitals in Karachi, Pakistan, in 2009-2010. Materials and Methods: We questioned 500 healthcare workers of all ages and both sexes, who wore CL, about compliance with advice on care and any complications due to improper hygiene practices. Ethical approval was obtained. Chi-square tests were used to determine significance and p-value less than 0.05 was considered statistically significant. Results: Of the total CL users, 385 (77% were females. Most (75% respondents wore CL to correct myopia, whereas 54% wore CL only occasionally. Surprisingly, only 24% knew the CL cleaning protocol. Lens solution was changed daily by 33% of users and after more than 2 weeks by 42%. Although 412 (82% participants practised reasonable hand hygiene before inserting CL, 88 (18% did not. Infection and eye dryness were statistically significantly (P < 0.01 associated with sex, hand-washing, and frequency of CL use. Conclusion: Noncompliance with the CL protocol was common among healthcare workers in our society. This behavior calls for targeted health education and awareness programs for healthcare workers.

    The genetic and inflammatory response pathways elicited following plutonium exposure in archival lung tissue of an occupationally exposed human and experimentally exposed beagle dogs were investigated. These pathways include: tissue injury, apoptosis and gene expression modifications related to carcinogenesis and inflammation. In order to determine which pathways are involved, multiple lung samples from a plutonium exposed worker (Case 0269), a human control (Case 0385), and plutonium exposed beagle dogs were examined using histological staining and immunohistochemistry. Examinations were performed to identify target tissues at risk of radiation-induced fibrosis, inflammation, and carcinogenesis. Case 0269 showed interstitial fibrosis in peripheral and subpleural regions of the lung, but no pulmonary tumors. In contrast, the dogs with similar and higher doses showed pulmonary tumors primarily in brochiolo-alveolar, peripheral and subpleural alveolar regions. The TUNEL assay showed slight elevation of apoptosis in tracheal mucosa, tumor cells, and nuclear debris was present in the inflammatory regions of alveoli and lymph nodes of both the human and the dogs. The expression of apoptosis and a number of chemokine/cytokine genes was slightly but not significantly elevated in protein or gene levels compared to that of the control samples. In the beagles, mucous production was increased in the airway epithelial goblet cells and glands of trachea, and a number of chemokine/cytokine genes showed positive immunoreactivity. This analysis of archival tissue from an accidentally exposed worker and in a large animal model provides valuable information on the effects of long-term retention of plutonium in the respiratory tract and the histological evaluation study may impact mechanistic studies of radiation carcinogenesis.

    This paper investigates the patient response to a medical social worker in a glaucoma clinic. The literature suggests that medical social workers are effective in a variety of health care settings, yet the efficacy of a medical social worker in an adult ophthalmic setting has not been studied. We present the results of a retrospective chart review of 50 patients with glaucoma referred to a medical social worker between January 5, 2015 and June 31, 2015 in an outpatient clinic of an urban eye hospital. Clinical and demographic data, as well as the data from a quality of care questionnaire, were collected for each patient. Patients rated their interaction with the medical social worker as highly positive (mean = 4.75, 5-point Likert scale), and nearly 90 % of patients expressed interest in future contact with the social worker. Additionally, most patients reported that the social worker resolved the issues they were facing (61.1 %), supported them in seeing their ophthalmologist (70.6 %), and helped them to manage their glaucoma (69.7 %). Reported barriers to glaucoma care were emotional distress; cost of office visits and medications; lack of medical insurance; transportation; poor medication adherence; impairment of daily activities; follow-up adherence; and language. As vision loss from glaucoma is irreversible, it is important to detect and treat patients at early stages of the disease. Therefore, it is imperative for patients to regularly visit their eye care providers and adhere to treatment and follow-up recommendations. This study suggests that a medical social worker could play a pivotal role in helping patients with glaucoma overcome barriers to treatment and facilitate disease management. PMID:26860278

  19. Knowledge, attitude and practices about needle stick injuries in health care workers

    International Nuclear Information System (INIS)

    Objectives: To assess knowledge, attitude and practices about needle stick Injuries in health care workers. Study type, settings and duration: Hospital based study carried out at Pakistan Institute of Medical Sciences, Islamabad, from August 2010 to November 2010. Subjects and Methods: A self administered 19 items questionnaire was prepared which contained information about needle stick injuries, its awareness, frequency of injury and the protocols that were followed after an injury had occurred. These questionnaires were given to 500 health care workers working in different wards and theaters of the hospital after obtaining their informed written consent. The health care workers included doctors, nurses and paramedical staff of Pakistan Institute of Medical Sciences, Islamabad. The data was entered and analyzed using SPSS version 15. Results: A total of 500 health care workers filled the questionnaire and returned it. Out of these 416(83.2%) reported ever experiencing needle stick injuries in their professional life. Health care workers working in Emergency department were most frequently affected (65%) followed by those working in different wards (27%) and operation theatre (8%). Most (93.6%) workers had knowledge about needle stick injuries and only 6.4% were not aware of it. Needle stick injury occurred from a brand new (unused) syringe in 51.2% cases, while in 32.8% cases, the needle caused an injury after it had been used for an injection. In 5% cases, injury occurred with blood stained needles. The commonest reasons for needle injury in stick injuries were heavy work load (36.8%) followed by hasty work (33.6%) and needle recapping (18.6%). About 66% health care workers were already vaccinated against hepatitis B. Only 13% workers followed universal guidelines of needle stick injuries and no case was reported to hospital authorities. Conclusions: Health care workers had inadequate knowledge about the risk associated with needle stick injuries and do not

    Full Text Available Natural rubber latex allergy is a new illness whose prevalence has reached epidemic proportions in highly exposed populations such as health care workers and who has chronic illness. After anaphylactic type reactions due to latex has been shown as case reports. The major risk factors in latex are intense exposure to latex allergens (surgical gloves, catheters, etc, atopy, hand eczema, female gender, history of multiple operations and dental interventions. An association between latex allergy and allergy to various fruits (banana, kiwi, avocado, pineapple, etc has been reported. Latex allergy is responsible for a wide spectrum of clinical symptoms ranging from a mild dermatitis to severe anaphylaxis. In this report, we present that latex related systemic allergic reactions cases; the first one is 24 years old nurse woman who is working at the blood bank in our hospital and the other one is 32 years old woman patient who has repeatative medical examination, and in vitro fertilisation therapy plan and suffered for systemic allergic reaction due to latex gloves which was used in her last concha operations.

    Pedro Torres-Gonzalez

    Full Text Available BACKGROUND: Human tuberculosis caused by M. bovis is a zoonosis presently considered sporadic in developed countries, but remains a poorly studied problem in low and middle resource countries. The disease in humans is mainly attributed to unpasteurized dairy products consumption. However, transmission due to exposure of humans to infected animals has been also recognized. The prevalence of tuberculosis infection and associated risk factors have been insufficiently characterized among dairy farm workers (DFW exposed in settings with poor control of bovine tuberculosis. METHODOLOGY/PRINCIPAL FINDINGS: Tuberculin skin test (TST and Interferon-gamma release assay (IGRA were administered to 311 dairy farm and abattoir workers and their household contacts linked to a dairy production and livestock facility in Mexico. Sputa of individuals with respiratory symptoms and samples from routine cattle necropsies were cultured for M. bovis and resulting spoligotypes were compared. The overall prevalence of latent tuberculosis infection (LTBI was 76.2% (95% CI, 71.4-80.9% by TST and 58.5% (95% CI, 53.0-64.0% by IGRA. Occupational exposure was associated to TST (OR 2.72; 95% CI, 1.31-5.64 and IGRA (OR 2.38; 95% CI, 1.31-4.30 adjusting for relevant variables. Two subjects were diagnosed with pulmonary tuberculosis, both caused by M. bovis. In one case, the spoligotype was identical to a strain isolated from bovines. CONCLUSIONS: We documented a high prevalence of latent and pulmonary TB among workers exposed to cattle infected with M. bovis, and increased risk among those occupationally exposed in non-ventilated spaces. Interspecies transmission is frequent and represents an occupational hazard in this setting.

    Full Text Available Background: In Nigeria, the shortage of health workers is worst at the primary health care (PHC level, especially in rural communities. And the responsibility for PHC – usually the only form of formal health service available in rural communities – is shared among the three tiers of government (federal, state, and local governments. In addition, the responsibility for community engagement in PHC is delegated to community health committees. Objective: This study examines how the decentralisation of health system governance influences retention of health workers in rural communities in Nigeria from the perspective of health managers, health workers, and people living in rural communities. Design: The study adopted a qualitative approach, and data were collected using semi-structured in-depth interviews and focus group discussions. The multi-stakeholder data were analysed for themes related to health system decentralisation. Results: The results showed that decentralisation influences the retention of rural health workers in two ways: 1 The salary of PHC workers is often delayed and irregular as a result of delays in transfer of funds from the national to sub-national governments and because one tier of government can blame failure on another tier of government. Further, the primary responsibility for PHC is often left to the weakest tier of government (local governments. And the result is that rural PHC workers are attracted to working at levels of care where salaries are higher and more regular – in secondary care (run by state governments and tertiary care (run by the federal government, which are also usually in urban areas. 2 Through community health committees, rural communities influence the retention of health workers by working to increase the uptake of PHC services. Community efforts to retain health workers also include providing social, financial, and accommodation support to health workers. To encourage health workers to stay

    Full Text Available Abstract Background Most cases of hepatitis B virus (HBV infection and subsequent liver diseases can be prevented with universal newborn HBV vaccination. The attitudes of health care workers about HBV vaccination and their willingness to recommend vaccine have been shown to impact HBV vaccination coverage and the prevention of vertical transmission of HBV. The purpose of this study was to ascertain the factors associated with health care worker recommendations regarding newborn HBV vaccination. Methods A cross-sectional study of prevalence and awareness of hepatitis B and hepatitis B vaccine was conducted among randomly selected physicians and nurses employed in seven hospitals in Georgia in 2006 and 2007. Self-administered questionnaires included a module on recommendations for HBV, HCV and HIV. Results Of the 1328 participants included in this analysis, 36% reported recommending against hepatitis B vaccination for children, including 33% of paediatricians. Among the 70.6% who provided a reason for not recommending HBV vaccine, the most common concern was an adverse vaccine event. Unvaccinated physicians and nurses were more likely to recommend against HBV vaccine (40.4% vs 11.4%, PR 3.54; 95% CI: 2.38, 5.29. Additionally, health care worker age was inversely correlated with recommendations for HBV vaccine with older workers less likely to recommend it. Conclusion Vaccinating health care workers against HBV may provide a dual benefit by boosting occupational safety as well as strengthening universal coverage programs for newborns.

  11. Where Caring Is Sharing: Evolving Ethical Considerations in Tuberculosis Prevention Among Healthcare Workers.

    2016-05-15

    In many settings, the dedication of healthcare workers (HCWs) to the treatment of tuberculosis exposes them to serious risks. Current ethical considerations related to tuberculosis prevention in HCWs involve the threat posed by comorbidities, issues of power and space, the implications of intersectoral collaborations, (de)professionalization, just remuneration, the duty to care, and involvement in research. Emerging ethical considerations include mandatory vaccination and the use of geolocalization services and information technologies. The following exploration of these various ethical considerations demonstrates that the language of ethics can fruitfully be deployed to shed new light on policies that have repercussions on the lives of HCWs in underresourced settings. The language of ethics can help responsible parties get a clearer sense of what they owe HCWs, particularly when these individuals are poorly compensated, and it shows that it is essential that HCWs' contribution be acknowledged through a shared commitment to alleviate ethically problematic aspects of the environments within which they provide care. For this reason, there is a strong case for the community of bioethicists to continue to take greater interest both in the micro-level (eg, patient-provider interactions) and macro-level (eg, injustices that occur as a result of the world order) issues that put HCWs working in areas with high tuberculosis prevalence in ethically untenable positions. Ultimately, appropriate responses to the various ethical considerations explored here must vary based on the setting, but, as this article shows, they require thoughtful reflection and courageous action on the part of governments, policy makers, and managers responsible for national responses to the tuberculosis epidemic.

    Full Text Available ABSTRACT: INTRODUCTION: Ten to thirty percent of the patients admitted to hospitals in India acquire nosocomial infections as against 5% i n the developed world. The first and foremost principle of Universal Safety Precaution is “HANDWASHING”. But the Health Care Workers often forget to wash their hands before int eracting with the patient. Such contaminated hands plays major role in transmitting infections. HCWs are also at an increased risk of needle stick injuries. According to data fr om EPINet system, hospital workers incur approximately 30 needle stick injuries per 100 beds per year on average – an alarming figure by no exaggeration. (5 OBJECTIVE: To assess the knowledge and perception of HCWs toward s hand hygiene and to know the incident of NSI and the fac tors associated with it. STUDY METHOD: Cross sectional study with purposive sampling was car ried out in a tertiary care hospital. Out of 275 participants 55 were doctors, 143 nurses and 77 i nterns. Self administered questionnaire was used to collect information. RESULTS : Ninety one percent doctors, 86% interns and 81% nurses had good knowledge about hand hygiene. 73% d octors, 61% interns and 56% nurses knew the duration required for hand rub. The main h indrance for not practicing hand hygiene was due to lack of resources (37%. Knowledge abou t recapping of the needle was poor and incident of injury due to needle stick was 50% amon g nurses. CONCLUSIONS : Study demonstrated adequate knowledge regarding hand hygi ene. The knowledge should be converted into practice. There is a need for educati onal programme about universal precautions especially about handling of the sharps

    E-mediated sensitisation to common allergens and self-reported health symptoms were assessed using logistic regression and generalised additive modelling. Adjustments were made for study, age, sex, atopic predisposition, smoking habit and farm childhood. Heterogeneity was assessed by analysis stratified by study. Results...... levels above 100 EU/m3 significantly increased the risk of chronic bronchitis (p<0.0001). Stratification by farm childhood showed no effect modification except for allergic sensitisation. Only among workers without a farm childhood, endotoxin exposure was inversely associated with allergic sensitisation....... Heterogeneity was primarily present for biofuel workers. Conclusions Occupational endotoxin exposure has a protective effect on allergic sensitisation and hay fever but increases the risk for organic dust toxic syndrome and chronic bronchitis. Endotoxin's protective effects are most clearly observed among...

    1991-01-01

    Respiratory function tests were performed in 110 workers who were occupationally exposed to asbestos-cement dust in the period from 7 to 34 years. Due to the results obtained, the following groups of patients were analysed according to years of asbestos-cement exposure and the habit of cigarette smoking. The analysis of the years of exposure to asbestos-cement dust revealed that the workers with the exposure longer than 16 years had significantly lower FVC and FEV1 (P less than 0.001) than the workers whose exposure was less than 16 years. In view of increasing age this deterioration proved to be significantly higher than it had been expected. Of all the subjects included in this study 7% of them were found to have a partial respiratory insufficiency. The phenomenon could not be explained either by the length of exposure or by the habit of cigarette smoking. In the smoking subjects with the longest exposure, a markedly lower SaHbO2 was found as compared to the smokers with the shortest exposure (P less than 0.05). PMID:1766985

    Full Text Available Oxidative stress status and Acetylcholinesterase (AChE activity were studied in blood samples obtained from 61 agricultural workers engaged in spraying organophosphorus (OP insecticides in the mango plantation, with a minimum work history of one year, in the age range of 12-55 years. Controls were age-matched, unexposed workers, who never had any exposure to OP pesticides. They were evaluated for oxidative stress markers MDA (end product of lipid peroxidation, reduced glutathione (GSH, and Acetylcholinesterase (AChE and butyrylcholinesterase (BChE levels in blood. The results showed a marked inhibition of the AChE and BChE activities in the sprayers as compared to the controls. The malondialdehyde(MDA, the last product of lipid peroxidation was found to be increased significantly in sprayers(p< 0.05, while depletion in the concentration of antioxidant glutathione(GSH was also observed in the sprayers but the difference was statistically not significant. It was concluded on the basis of biochemical analysis that pesticides sprayers are exposed to more oxidative stress as evidenced by the changes in antioxidant status. The measurement of the AChE and BChE activities in agricultural workers who spray OPs could be a good biomonitoring factor and is recommended to be performed on a regular basis.

  20. Burnout as a clinical entity--its importance in health care workers.

    Science.gov (United States)

    Felton, J S

    1998-05-01

    Burnout, viewed as the exhaustion of physical or emotional strength as a result of prolonged stress or frustration, was added to the mental health lexicon in the 1970s, and has been detected in a wide variety of health care providers. A study of 600 American workers indicated that burnout resulted in lowered production, and increases in absenteeism, health care costs, and personnel turnover. Many employees are vulnerable, particularly as the American job scene changes through industrial downsizing, corporate buyouts and mergers, and lengthened work time. Burnout produces both physical and behavioural changes, in some instances leading to chemical abuse. The health professionals at risk include physicians, nurses, social workers, dentists, care providers in oncology and AIDS-patient care personnel, emergency service staff members, mental health workers, and speech and language pathologists, among others. Early identification of this emotional slippage is needed to prevent the depersonalization of the provider-patient relationship. Prevention and treatment are essentially parallel efforts, including greater job control by the individual worker, group meetings, better up-and-down communication, more recognition of individual worth, job redesign, flexible work hours, full orientation to job requirements, available employee assistance programmes, and adjuvant activity. Burnout is a health care professional's occupational disease which must be recognized early and treated. PMID:9800422

    To provide direct estimates of risk of cancer after protracted low doses of ionising radiation and to strengthen the scientific basis of radiation protection standards for low-dose ionising radiation exposure. Published papers referring to 20 low-dose ionising radiation-exposed cohorts among nuclear industry workers with Standardized Mortality Ratios (SMR) were recta-analyzed in fixed and random effect models. The significantly deficient Meta-SMRs for all deaths (0.73; 95% CI: 0.66-0.80), all cancers (0.83; 95% CI: 0.77- 0.91), lung cancer (0.93; 95% CI: 0.90-0.95), non-Hodgkin lymphoma (0.88; 95% CI: 0.78- 0.99), esophagus cancer (0.83; 95% CI:0.76-0.91), colorectal cancer (0.88; 95% CI: 0.83-0.94), stomach cancer (0.81; 95% CI: 0.76-0.86) were observed. The Meta-SMRs for leukemia, multiple myeloma, Hodgkin's disease were found to be no significant difference with normal populations. There was no excessive risk of cancers among nuclear workers exposed to low-doses and low-dose rates ionizing radiation. (authors)

  2. Low Dose-Rate Effects on Chromosomal Aberrations in Workers Occupationally Exposed to Ionising Radiation

    International Nuclear Information System (INIS)

    Full text: Occupational exposure to ionising radiation can be assessed by chromosomal aberrations detected in peripheral blood lymphocytes. Blood samples were collected from 47 occupationally exposed individuals (X-ray diagnostic machines and industrial gamma defectoscopy). The chromosomal aberrations were analysed from at least 500 metaphases per person and their frequencies were compared with those obtained from 110 control individuals. It has been noticed the higher frequency of chromosomal aberrations in the exposed group related to the control. The increase was analysed according to the age groups (31-40, 41-50, and 51-60), sex and duration of employment. The higher frequency of dicentrics was not directly correlated with the age or duration of employment in the exposed group. The acentric fragments were encountered with much higher frequency in the exposed group. The chromosomal aberrations induced by low dose-rate in occupationally exposed people revealed the degree of individual sensitivity and the severity of the initial damage depending on the biological-pathological conditions.

  3. Development of measurement method using TLD for workers occupation personally exposed to 125I seed source in the implant

    International Nuclear Information System (INIS)

    Objective: To explore the method for measuring and calculating both absorbed dose and effective dose received in organ and tissues of occupational workers by using TLDs for the implantation of 125I seed sources. Methods The experiments with 60Co γ-rays were carried out for the stability. A group of TLD chips was exposed to 125I seed sources to establish standard dose curve for air kerma. During the 125I seed implantation, the TLD chips were pasted to 13 locations like thyroid inside and outside the lead aprons worn by occupational workers to measure average absorbed dose and calculate the absorbed doses and effective to organs and tissues. Results: For 3 cases of prostate cancers with implantation of 125I seeds, the worker's organs and tissues received the absorbed dose 0.02 -3.80 μ Gy and effective dose 0.06- 1.81 μSv outside lead aprons and the highest absorbed dose 2.35 μ Gy and effective 0.02 μSv inside lead aprons, respectively, with more than 65.9% of rays shielded. For 3 cases of brain cancers with implantation of 125I seeds, the workers received the absorbed dose 0.23 - 11.31 μGy and effective dose 0.88-4.07 μSv outside lead aprons and the highest absorbed dose 2.22 μ Gy and effective dose 0.09 μSv inside lead aprons, respectively, with more than 54.5% of rays shielded. For 3 cases of lung cancers with implantation of 125I seeds, the workers received the absorbed dose 0.03 - 14.78 μGy and effective dose 0.35 -7.59 μSv outside lead aprons and the highest absorbed dose 4.09 μGy and effective 0.22 μSv inside lead aprons, respectively, with more than 58.4% of rays shielded. For 2 cases of mediastinum cancers with implantation of 125Iseeds, the workers received the absorbed dose 0.06 - 74.91 μGy and effective dose 0.83-17.96 μSv outside lead aprons and the highest absorbed dose 10.29 μGy and effective 0.5 μSv inside lead aprons, respectively, with more than 85% of rays shielded.

    Full Text Available Abstract Background Gender related differences in respiratory disease have been documented. The aim of this study was to investigate gender related differences in respiratory findings by occupation. We analyzed data from 12 of our previously published studies. Methods Three thousand and eleven (3011 workers employed in "organic dust" industries (1379 female and 1632 male were studied. A control group of 806 workers not exposed to any kind of dust were also investigated (male = 419, female = 387. Acute and chronic respiratory symptoms and lung function were measured. The weighted average method and the Mantel-Haentszel method were used to calculate the odds ratios of symptoms. Hedge's unbiased estimations were used to measure lung function differences between men and women. Results There were high prevalences of acute and chronic respiratory symptoms in all the "dusty" studied groups compared to controls. Significantly less chronic cough, chronic phlegm as well as chronic bronchitis were found among women than among men after the adjustments for smoking, age and duration of employment. Upper respiratory tract symptoms by contrast were more frequent in women than in men in these groups. Significant gender related lung function differences occurred in the textile industry but not in the food processing industry or among farmers. Conclusion The results of this study suggest that in industries processing organic compounds there are gender differences in respiratory symptoms and lung function in exposed workers. Whether these findings represent true physiologic gender differences, gender specific workplace exposures or other undefined gender variables not defined in this study cannot be determined. These data do not suggest that special limitations for women are warranted for respiratory health reasons in these industries, but the issue of upper respiratory irritation and disease warrants further study.

    Occupational exposure to organic solvents present in paints is responsible for an increased production of reactive species, thus enabling the development of several diseases. Besides, both exo- and endogenous antioxidant defense systems are necessary to avoid oxidative tissue damage. This study investigated possible protective effects of the exo- and endogenous antioxidants on oxidative damage in painters occupationally exposed to organic solvents (n = 42) and controls (n = 28). Retinol, lycopene and β-carotene were significantly lower in the exposed group. Despite the fact that blood toluene was below the biological exposure limits, malondialdehyde levels and antioxidant enzyme activities were increased, whereas reduced glutathione levels were decreased in painters, compared to nonexposed subjects. Moreover, multivariate regression models showed that reduced glutathione and carotenoids (mainly β-carotene) have the major influence on lipid peroxidation (LPO). The present work suggests that the exogenous antioxidants, such as carotenoids, could protect occupationally exposed subjects to xenobiotics from LPO. PMID:23841515

    Full Text Available Abstract Background Through a case control seroprevalence study, we sought to determine the association of Toxoplasma gondii infection with occupational exposure to unwashed raw fruits and vegetables. Methods Subjects, numbering 200, who worked growing or selling fruits and vegetables, and 400 control subjects matched by age, gender, and residence were examined by enzyme immunoassays for the presence of anti-Toxoplasma IgG and IgM antibodies. Socio-demographic, clinical, and behavioral characteristics from the study subjects were obtained. Results Of the 200 fruit and vegetable workers, 15 (7.5% of whom, and 31 (7.8% of the 400 controls were positive for anti-Toxoplasma IgG antibodies (P = 0.96. Anti-Toxoplasma IgM antibodies were found in 2 (1% of the fruit workers and in 11 (2.8% of the control subjects (P = 0.23. Seroprevalence of Toxoplasma antibodies increased with age (P = 0.0004. In addition, seropositivity to Toxoplasma was associated with ill status (P = 0.04, chronic tonsillitis (P = 0.03, and reflex impairment (P = 0.03. Multivariate analysis showed that Toxoplasma infection was associated with consumption of raw meat (OR = 5.77; 95% CI: 1.15-28.79; P = 0.03, unwashed raw fruits (OR = 2.50; 95% CI: 1.11-5.63; P = 0.02, and living in a house with soil floors (OR = 3.10; 95% CI: 1.22-7.88; P = 0.01, whereas Toxoplasma infection was negatively associated with traveling abroad (OR = 0.28; 95% CI: 0.12-0.67; P = 0.005. Conclusions This is the first report of seroprevalence and contributing factors for Toxoplasma infection in workers occupationally exposed to unwashed raw fruits and vegetables, and the results may help in the design of optimal preventive measures against Toxoplasma infection especially in female workers at reproductive age.

    2000-05-01

    The Workplace Managed Care Cooperative Agreement project targets 3,300 health care professionals in hospital, specialty clinic, and primary care settings located in metropolitan New Mexico communities. This project will evaluate whether enhancements to existing substance abuse prevention/early intervention programs can prevent the onset of risky drinking, reduce prevalence of risky drinking, better identify employees who abuse alcohol and drugs, and improve employee wellness. This article describes one such enhancement (Project WISE [Workplace Initiative in Substance Education]), implemented at Lovelace Health Systems. Project WISE includes relatively low-cost elements such as substance abuse awareness training, information on how to reduce drinking, and brief motivational counseling. Evaluation will consist of baseline comparisons of the intervention and comparison sites, a process evaluation, a qualitative analysis using focus groups, and an outcome evaluation using health and work records. Methodological challenges, solutions, and implications for researchers undertaking similar projects are presented. PMID:10795124

    Full Text Available OBJECTIVE: To ascertain the extent to which screening procedures (with and without evidence of effectiveness are practiced among health care workers at a tertiary-care hospital in Sao Paulo, Brazil. METHODS: From February 2001 to September 2003, a cross-sectional study involving physicians, nurses and nursing assistants (aged 40 to 69 years was carried out at a tertiary-care hospital in the city of Sao Paulo, Brazil. Subjects were interviewed using a questionnaire that addresses 17 procedures with grades of recommendation of A, B, C, D or E, in accordance with the 1996 United States Preventive Services Task Force guidelines for routine screening. RESULTS: Of the 333 health care workers included, 228 (68.5% were female. The mean age was 48.8 (SD 6.6 years. Most subjects had undergone screening for hypertension (blood pressure measurement and lipid abnormalities (cholesterol testing. Screening for breast and cervical cancer was common among females. Resting electrocardiography, serum glucose testing, urine tests, chest X-rays and serum prostate-specific antigen testing were also quite common. However, only 6 (1.8% of the subjects had undergone screening for colorectal cancer (fecal occult blood test or sigmoidoscopy. CONCLUSIONS: A sizeable proportion of health care workers underwent screening procedures that are not recommended or for which there was insufficient evidence of a benefit. Conversely, certain recommended procedures were performed on a small proportion of such workers. These results indicate that the Brazilian National Ministry of Health must develop nationwide evidence-based screening recommendations and disseminate such recommendations among health care professionals in Brazil.

    2016-01-01

    This study examines the determinants of emotional laborers'--social workers in health care organizations--job satisfaction and their public service motivation in using a structural equation model and provides empirical evidence regarding what contributes to job satisfaction or burnout in these workers. Among several latent variables, this study confirmed that false face significantly decreases the job satisfaction of social worker and is positively associated with burnout. In addition, commitment to public interest increases social workers' job satisfaction significantly. This study has implications for the management of emotional labor. By educating emotional laborers to reappraise situations to increase their job satisfaction and avoid burnout, reappraisal training and education are expected to result in increases in positive emotions and decreases in negative emotions, and to improve employees' performance in their organizations.

  1. Telomere Length in Aged Mayak PA Nuclear Workers Chronically Exposed to Internal Alpha and External Gamma Radiation.

    Scherthan, Harry; Sotnik, Natalia; Peper, Michel; Schrock, Gerrit; Azizova, Tamara; Abend, Michael

    2016-06-01

    Telomeres consist of GC-rich DNA repeats and the "shelterin" protein complex that together protect chromosome ends from fusion and degradation. Telomeres shorten with age due to incomplete end replication and upon exposure to environmental and intrinsic stressors. Exposure to ionizing radiation is known to modulate telomere length. However, the response of telomere length in humans chronically exposed to radiation is poorly understood. Here, we studied relative telomere length (RTL) by IQ-FISH to leukocyte nuclei in a group of 100 workers from the plutonium production facility at the Mayak Production Association (PA) who were chronically exposed to alpha-emitting ((239)Pu) radiation and/or gamma (photon) radiation, and 51 local residents serving as controls, with a similar mean age of about 80 years. We applied generalized linear statistical models adjusted for age at biosampling and the second exposure type on a linear scale and observed an age-dependent telomere length reduction. In those individuals with the lowest exposure, a significant reduction of about 20% RTL was observed, both for external gamma radiation (≤1 Gy) and internal alpha radiation (≤0.05-0.1 Gy to the red bone marrow). In highly exposed individuals (>0.1 Gy alpha, 1-1.5 Gy gamma), the RTL was similar to control. Stratification by gender revealed a significant (∼30%) telomere reduction in low-dose-exposed males, which was absent in females. While the gender differences in RTL may reflect different working conditions, lifestyle and/or telomere biology, absence of a dose response in the highly exposed individuals may reflect selection against cells with short telomeres or induction of telomere-protective effects. Our observations suggest that chronic systemic exposure to radiation leads to variable dose-dependent effects on telomere length. PMID:27340887

    2012-01-01

    Full Text Available Optimism has several orientations. One such outlook is a general tendency to regard the world as a positive place, accepting difficulties as mere challenges instead of impassable barriers. Among health care workers, optimism improves their level of functioning, their patients’ satisfaction, and their therapeutic results. Optimistic staff members report feeling less pressure, use fewer avoidance strategies, focus on practical problem solutions, seek social support, and have more trust in people and organizations. The aim of this article is to provide a review of the literature concerning the role of optimism, both in daily life and in crisis situations. An attempt was made to find the linkage between optimism among health care workers during disasters and their active response, with special emphasis on the relationship between optimism and knowledge, feelings or behavior. Based on the literature, optimism was found to be helpful both in daily medical work and in cases of medical emergencies. Optimism was also revealed one of the key components of resilience and self-efficacy. Therefore, it is recommended to consider strengthening the optimism through initiative programs. Obtaining optimism can be included in toolkit preparedness for health care workers in order to confront the complications in the aftermath of disaster. These programs, together with appropriate information, social support, professional trust, and leaders modeling behavior, will raise the well-being and enhance coping skills of the health care workers during and aftermath of disaster scenarios.

  11. ROMANIAN SOCIAL CARE WORKERS' EXPOSURE TO WORKPLACE VIOLENCE

    Directory of Open Access Journals (Sweden)

    Oana I. ZIGMAN

    2014-06-01

    Full Text Available Workplace violence in the social care sector is not a problem that appeared overnight. It was and still is a major concern, and its disastrous effects, on both organization and employees have been largely documented in various papers and studies around the world. This study analyses social care workers’ perceptions and experiences with workplace violence, phenomenon which, until a few years ago, has been largely ignored in the Romanian research field, and is still considered to this day a taboo subject in the organizational environment. Even if most employers recognize its general existence they tend to deny or refuse to accept that their institution or company is affected by it. The present paper will provide information concerning problematic issues in studying the phenomenon and will try to provide an image of the social care workers’ perception and attitude towards risk and workplace violence. The research will try to identify differences in experience, exposure and resistance to violence in the workplace based on various variables like sex or job characteristics.

    2009-02-01

    Full Text Available Abstract Background Examination of consultation data in a variety of primary care settings in Tanzania shows that, while psychoses are routinely diagnosed and treated at primary care level, depression is rarely recorded as a reason for consultation. Since, epidemiological studies elswhere show that depression is a much more common disorder than psychosis, a series of studies were undertaken to elucidate this apparent paradox in Tanzania and inform mental health policy; firstly, a household prevalence study to ascertain the prevalence of common mental disorders at community level in Tanzania; secondly, a study to ascertain the prevalence of common mental disorders in primary care attenders; and thirdly, a study to ascertain the current status of the knowledge, attitude and practice pertaining to depression among primary health care workers. This paper reports the findings of the latter study. Methods All the primary health care workers (N = 14 in four primary health care centres in Tanzania were asked to complete the Depression Attitude Questionnaire, which assesses the health worker's knowledge and attitude towards the causes, consequences and treatment of depression. Results The majority of respondents felt that rates of depression had increased in recent years, believed that life events were important in the aetiology of depression, and generally held positive views about pharmacological and psychological treatments of depression, prognosis and their own involvement in the treatment of depressed patients. However, the majority of respondents felt that becoming depressed is a way that people with poor stamina deal with life difficulties. Conclusion The findings suggest a need to strengthen the training of primary health care workers in Tanzania about the detection of depression, pharmacological and psychological treatments, and psychosocial interventions.

  13. DNA damage in female workers exposed to pesticides in banana plantations at Limon, Costa Rica

    International Nuclear Information System (INIS)

    Pesticide use in Costa Rica is very high and all year round. A high percentage of what is sprayed remains in the environment and in the living organisms around. This situation brings contamination and health problems to people in contact with them. The onset of adverse effects may be in the short or long term, and symptoms vary widely, from headaches to cancer. Much research in the area has been devoted to acute or chronic effects, and not until recently to the genotoxic effect of pesticides. This study evaluated the genotoxic effect of pesticide used in banana packing activities, using the comet assay (single cell electrophoresis) as the biological marker in lymphocytes. This was a cases-control double blind study of 30 exposed women from 15 banana farms and 28 women not occupationally exposed to pesticides from the same geographic area. Results show damage to single straded DNA after working from 5 to 15 years (R2=0.12). In Costa Rica we do not have an historical record of the kind of pesticides used in banana farms, the period of time and for how long were they used. This prevented further analysis concerning dose, frequency of exposure and use of new or old kind of pesticides in the farms in relation to DNA damage. The comet assay is of value in the genetic monitoring of pesticide exposed populations. (Author)

  14. Analysis of whole-body doses received by occupationally exposed workers in Ireland (1996-1999)

    International Nuclear Information System (INIS)

    The work described in this paper is based on the results of routine whole-body measurements carried out by the Radiological Protection Institute of Ireland Dosimetry Service from 1996 to 1999. Data on the occupational radiation exposures of monitored personnel are examined and have been found to follow the skewed distribution reported by UNSCEAR. The annual average effective dose for each major work practice over the 4 years is given and compared with the UNSCEAR reference value of 1.1 mSv per year for all occupations. Evidence suggests that improvements in procedures and the use of better equipment have resulted in a reduction in the number of workers receiving measurable doses. (author)

  15. Frequency of somatic mutations in a population of occupationally exposed radiation workers

    International Nuclear Information System (INIS)

    Epidemiological studies of cancer incidence are unable to provide an accurate estimate of the excess risk due to low level radiation exposure. Advances in the understanding of the aetiology of malignant disease suggest an alternative approach. Cancer is induced by somatic mutations, therefore somatic mutation frequencies should correlate both with radiation exposure and with risk. This should be equally true of mutations which are not specific to cancer because radiation acts randomly on the genome. Mutation frequencies at the glycophorin-A (CPA) locus have previously been found to increase after high radiation doses. Here we demonstrate the application of the GPA assay to occupational exposure. A weak positive association was found between the ln of cumulative dose and ln of N0 variant cell frequency (p=0.04). This was not apparently confounded by age or smoking but was dependent on workers with doses greater than 500 mSv. The average N0 frequency per million cells for workers with doses up to 20 mSv was 9.43 (SD=8.76, n=77) compared to 19.72 (SD=15.42, n=16) for those with doses above 500 mSv. When tested using a likelihood ratio statistic the data were better fitted by a threshold model comparing those with doses above and below 500 mSv than by a linear, no-threshold model. Although this data set is relatively small it demonstrates the potential of using somatic mutations for resolving the current uncertainties about the effects of low does of radiation. With recent developments in molecular biology it should, in future, be possible to determine the frequency of specific cancer-associated mutations. (authors)

  16. Health Care Workers' Beliefs and Practices Around Pap Screening for Adolescents Seeking Contraception.

    Science.gov (United States)

    Gabzdyl, Elizabeth; Engstrom, Janet L; McFarlin, Barbara L

    2015-01-01

    Adolescents often avoid seeing a health care provider to obtain contraception because they do not want to undergo a pelvic exam and Pap screening for fear of stress, pain or embarrassment. The purpose of this quality improvement project was to study health care workers, attitudes and beliefs about Pap screening and to educate them on the latest evidence-based guidelines, with the hope of ultimately decreasing unnecessary screening. Results showed a modest reduction in the frequency of Pap screening; however, many adolescents continued to undergo unnecessary Pap screening. The reluctance of health care workers to change their practice demonstrates the need for better methods of translating evidence-based guidelines into practice. PMID:26058904

The mean urinary 2,5-HD was 0.52 mg/L (free and 2.88 mg/L (total, this difference being significant (Student t-test, p < 0.05. The differences in the results according to the sample treatment support the need to modify the current Brazilian legislation, which proposes the analysis of 2,5-HD without indicating whether it is the free or total metabolite.

  20. The monitoring of potential incorporations of occupationally exposed workers in Germany. Pt. 1. The regulatory system for incorporation monitoring

    International Nuclear Information System (INIS)

    In Germany a new standard has been defined for the monitoring of workers occupationally exposed to radioactive material. The German government adopted three guidelines which define general rules for the monitoring of exposures, regulate the assessment of exposures by incorporated radiation emitters and set the requirements measuring laboratories have to fulfill. The purpose of the approach was to establish a consistent system, that 1. defines clear criteria for the necessity of routine and special monitoring programs, 2. ensures that dose assessments are as reliable as necessary, 3. standardizes as far as possible the procedures of dose assessments, and 4. guarantees the necessary quality standards. In accordance with the underlying Radiation Protection Ordinance the scientific basis of this regulatory system is formed by the publications 30, 48 and 54 of ICRP, but the structure easily allows the adoption of more recent knowledge.

  1. Sample preparation and system calibration for proton-induced X-ray emission analysis of hair from occupationally exposed workers

    International Nuclear Information System (INIS)

    Blood and urine collections are commonly used to monitor trace element concentration in the body. Hair may also be used. The concentration of many elements is much higher in hair than in either blood or urine and may provide a ready record of a period of exposure to heavy metals. Proton-induced X-ray emission (PIXE) has been used to study trace elements in hair. A method of preparing samples by charring hair and mixing with yttrium-spiked graphite has been developed. Thick targets suitable for PIXE analysis are made. The trace elements K, Ca, Tl, Mn, Fe, Ni, Cu, Zn, Pb, Br, Rb, and Sr are routinely measured in most samples and Cr, Co, As, Bi, Se, Zr, and Cd can be measured in occupationally exposed workers. Helium backscattering and elastic recoil detection are used to determine the major component H, C, N, O, and S. 23 references, 5 figures, 3 tables

    Health care-associated infection (HCAI) is the most frequent adverse event for hospitalized patients. Hand hygiene is a simple and effective solution to protect patients from HCAI. This study aimed to introduce hand hygiene to health care workers based on the World Health Organization guideline for reducing HCAI in Cambodia and to assess their behavioral patterns on hand hygiene. All health care workers at Kampong Cham provincial hospital had lectures and practice on hand hygiene in January 2012. The surveys for hand hygiene compliance (HHC) were performed after 6 months, 1 year and 2 years, respectively. The number of surgical site infections (SSI) was counted in 2011 and 2014. Our analysis used the data of 58 workers, who were observed at all three points, although 139 workers were observed during the study period. The average of HHC at 6 months, 1 year and 2 years were 62.37%, 85.76% and 80.36%, respectively. The improved group (HHC 2 years/1 year≧1) had 32 workers, whereas the worsened group (HHC 2 years/1 yearsex, age or occupations. The improved group had more workers of General (31.2% vs. 19.2%), Surgical (25.0% vs. 11.5%) and Infection (21.9% vs. 11.5%) categories compared to the worsened group. The incidence of SSI was improved from 32.26% in 2011 to 0.97% in 2014. Our results suggest that the education and the survey on hand hygiene are effective for reducing HCAI in Cambodia.

    Full Text Available AIM: As the influence of the variations in demographics, average incomes, and living conditions in the length of time, health systems sometimes need to be revised (e.g. size, comprehension, organization, etc. to meet health problems. As a consequence of these changes Model of Family Medicine (MFM has implemented in Sivas Province. This study, therefore, was done to evaluate the current knowledge of this model (MFM of the healthcare workers in inner city of Sivas. METHODS: This descriptive study was performed by face to face interview with 224 people (64,2% out of 349 healthcare workers in 19 primary care units in Sivas city. RESULTS: Nearly half of (49,1% healthcare workers affirmed that the project (MFM was pertaining to the Ministry of Health. Overall, 47,8% of healthcare workers did not suppose the MFM will be efficiently improve the health service. Additionally, healthcare workers believed that MFM will not improve the employees personal rights (60,7%, 73,2% of them declared that they worry about competitive pressure of their employment and scared of unemployment, and finally, 62,1% of them did not want to be a MFM personal in the future. CONCLUSION: Healthcare workers seemed to be poorly-informed about MFM, and they seemed worried about the application of the model. These problems should be taken into account by health system planners. [TAF Prev Med Bull 2009; 8(1.000: 13-16

    The HIV/AIDS epidemic has impacted all levels of society from the individual to the macro-economic. The continuing spread of infection around the world means that traditional methods of care and support are put under extreme pressure and many families lose their capacity to cope. Social workers are involved in providing care, counseling and support to those affected, and in developing programmes and other interventions to prevent the spread of the disease. Prevention and behaviour change are vital, but access to treatment is an ethical imperative, particularly in developing countries where the epidemic is most prevalent. Social work is a profession uniquely situated to demonstrate leadership in multi-sectoral collaboration in responding to this pandemic. Consequently this paper briefly reviews the scale and current nature of the epidemic and then considers how social workers can help build more compassionate policies at an international level. Social workers can help to create awareness of the negative effects of poverty, tackle gender inequity, help build more effective coalitions and partnerships, and work with other concerned groups and organisations to end stigma and discrimination. Using case examples the paper considers how social workers can help develop caring strategies that improve the lives of those living with HIV and AIDS. PMID:17521984

  6. Calibration of gamma cameras for in vivo monitoring of workers occupationally exposed to unsealed sources in nuclear medicine

    International Nuclear Information System (INIS)

    The routine manipulation of unsealed sources of various radionuclides for therapy and diagnostic in nuclear medicine poses a significant risk of internal exposure to the staff. The critical group includes workers who develop a variety of wet operations such as dose fractionation, preparation of radiopharmaceuticals and administration to the patients. The internal monitoring of such workers is recommended by the IAEA for those who might be exposed to effective doses above 1 mSv per year. According to the CNEN regulations, the Radiation Safety Officer of the facility is responsible for the selection of workers to be submitted to a routine monitoring. Currently, in Brazil, internal monitoring can only be executed in a few Laboratories located in governmental institutions, which turns unfeasible to implement such control in a national basis. On the other hand, such monitoring procedures could be carried out in the nuclear medicine services by using their image diagnose equipment. Among the radionuclides used in nuclear medicine, iodine-131 (131I) is still largely applied for diagnostic and treatment of thyroid diseases. The objective of this work is to establish a calibration protocol and an in vivo measurement procedure to evaluate incorporation of 131I using gamma cameras. The calibration factors - necessary to calculate the activity deposited in the human body - of two gamma cameras installed in University Hospitals located in the city of Rio de Janeiro were determined with a neck-thyroid phantom developed at the In Vivo Monitoring Laboratory of IRD. Both equipment presented equivalent sensitivities for in vivo measurement of 131I in thyroid. The results show that the gamma camera can be used for routine monitoring of 131I since the minimum detectable effective dose for a standard count time of 10 minutes is below 1 mSv. (author)

  9. Leukocyte subset analysis on blood from workers exposed to plutonium in 1944-45

    International Nuclear Information System (INIS)

    Monoclonal antibodies (MAbs) directed against cell surface markers were used to identify specific subpopulations of lymphocytes and monocytes obtained from 22 male subjects who had /sup 239/Pu exposures in 1944-45. Separated mononuclear cells were labelled simultaneously with fluoresceinated B1 (B cells), phycoerythrin Leu2a (T/sub S/ cells), LeμM3 with Texas-red goat-anti-mouse Ig and biotinylated Leμ3 with allophycocyanin avidin (T/sub H/ cells). In addition, the DNA-specific stain Hoechst 33342 was used to identify nucleated cells and to provide information on cell cycle status. Flow cytometric analysis using 3-color excitation (UV, 488 nm and 605 nm) was used, and 5 colors of emission were detected, corresponding to the four MAbs and Hoechst. The mononuclear cells were analyzed on the day of collection or after irradiation with 0, 50 or 200 rads followed by 6 days in culture with or without PHA stimulation. Marked differences in all measured parameters were found among the workers. The most striking response was a dose-related increase in the T/sub H//T/sub S/ ratio

  11. Long-term health effects of thorium compounds on exposed workers: the complete blood count

    International Nuclear Information System (INIS)

    Two hundred seventy-three men exposed to thorium and other rare earths between 1940 and 1973 at a plant which refined monazite sand were studied at Argonne National Laboratory from 1976 to 1980. In vivo measurements of body burden were made by counting gamma rays emitted by daughter products of retained thorium and by measuring exhaled thoron. Health status was ascertained through questionnaire, physical examination, and clinical laboratory tests. Measured body burden was found to be higher in those with a history of longer exposure. All parameters of the complete blood count were examined for evidence of an effect due to thorium. Comparisons of high and low body burden groups showed that only age and cigarette smoking had an effect on complete blood count parameters

    Full Text Available The objective of this study was to identify the association of blood lead level (BLL with mortality in inorganic lead-exposed workers of South Korea. A cohort was compiled comprising 81,067 inorganic lead exposed workers working between January 1, 2000, and December 31, 2004. This cohort was merged with the Korean National Statistical Office to follow-up for mortality between 2000 and 2008. After adjusting for age and other carcinogenic metal exposure, all-cause mortality (Relative risk [RR] 1.36, 95% confidence interval [CI] 1.03-1.79, digestive disease (RR 3.23, 95% CI 1.33-7.86, and intentional self-harm (RR 2.92, 95% CI 1.07-7.81 were statistically significantly higher in males with BLL >20 μg/dl than of those with BLL ≤10μg/dl. The RR of males with BLL of 10-20 μg/dl was statistically higher than of those with BLL ≤10μg/dl in infection (RR 3.73. 95% CI, 1.06-13.06. The RRs of females with 10-20 μg/dl BLL was statistically significantly greater than those with BLL <10μg/dl in all-cause mortality (RR 1.93, 95% CI 1.16-3.20 and colon and rectal cancer (RR 13.42, 95% CI 1.21-149.4. The RRs of females with BLL 10-20 μg/dl (RR 10.45, 95% CI 1.74-62.93 and BLL ≥20 μg/dl (RR 12.68, 95% CI 1.69-147.86 was statistically significantly increased in bronchus and lung cancer. The increased suicide of males with ≥20 μg/dl BLLs, which might be caused by major depression, might be associated with higher lead exposure. Also, increased bronchus and lung cancer mortality in female workers with higher BLL might be related to lead exposure considering low smoking rate in females. The kinds of BLL-associated mortality differed by gender.

    Exposure to blood-borne pathogens poses a serious risk to health care workers (HCWs). We review the risk and management of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infections in HCWs and also discuss current methods for preventing exposures and recommendations for postexposure prophylaxis. In the health care setting, blood-borne pathogen transmission occurs predominantly by percutaneous or mucosal exposure of workers to the blood or body fluids of infected patients. Prospective studies of HCWs have estimated that the average risk for HIV transmission after a percutaneous exposure is approximately 0.3%, the risk of HBV transmission is 6 to 30%, and the risk of HCV transmission is approximately 1.8%. To minimize the risk of blood-borne pathogen transmission from HCWs to patients, all HCWs should adhere to standard precautions, including the appropriate use of hand washing, protective barriers, and care in the use and disposal of needles and other sharp instruments. Employers should have in place a system that includes written protocols for prompt reporting, evaluation, counseling, treatment, and follow-up of occupational exposures that may place a worker at risk of blood-borne pathogen infection. A sustained commitment to the occupational health of all HCWs will ensure maximum protection for HCWs and patients and the availability of optimal medical care for all who need it. PMID:10885983

    To investigate the relationship between trans, trans-muconic acid (ttMA) as benzene metabolite of occupational workers and benzene concentration in air. Methods A rapid and sensitive high-performance liquid chromatography was developed to determine the level of urinary ttMA. ttMA was extrated from urinary samples in liquid-liquid phase a ODS (2) (5u) column (Φ4.6 mm× 150 mm) and detected at wavelength 264 nm in a UV detector using vanillic acid as an internal standard. The mobile phase was acetaticacid/tetrahydrofuran/methanol/water (v/v, 1:2:10:87). The method was validated with 56 urine samples collected from occupationally benzene-exposed individuals. Results A correlation coefficient (r = 0.9963 ) was found for ttMA ranging 0.10-10.00 μg/mL. The limit of detection was 0.10 μg/mL. The recovery and reproducibility were generally over 90%. There was a positive correlation between ttMA and benzene level in air. The equation was Y=0.859+0.108C (before work, r=-0.6200) or Y=1.980+0.179C (after work, r=0.7930). Conclusion This method can be used to determine and control the level of urinary ttMA in those who are occupationally exposed to benzene.

    Full Text Available BACKGROUND: The relative absence of inquiring data internationally, with regard to the relation of woman, family and work as important sources of stress, in the professional team of district nurses, gave the spark for the planning of present study. AIM: We have conducted a study to identify levels of stress, job satisfaction, and effects of the job to the family life and reversely, among district nurses (nurses and nurse assistantsworking in primary health care settings in central Greece (Thessaly. METHODS: Data were obtained regarding altogether 92 nurses by means of self-administered questionnaires using identical methods and items, with response rate 100%. RESULTS: District nurses believe in the necessity of high educational sufficiency for the achievement of professional evolution, present high levels of satisfaction from the object and their place of work. They reported high levels of stress that exceed the corresponding levels in the Greek population. Nurses appear to be more satisfied from work than nurse assistants. The implications of the findings for further research are considered.

    The aim of this study was to identify predictors of health care workers' glove use when there is a potential for blood exposure. The study hypothesis was that an extension of the theory of planned behavior would explain more of the variance in glove use behavior than the theory of reasoned action or theory of planned behavior. A random sample of nurses and laboratory workers (N = 527) completed a 26-item questionnaire with acceptable content validity and reliability estimates. Using structural equation modeling techniques, intention, attitude, and perceived risk were significant predictors of behavior. Perceived control and attitude were the significant determinants of intention. The theory of reasoned action was the most parsimonious model, explaining 70% of the variance in glove use behavior. The theory of planned behavior extension was a viable model to study behavior related to glove use and reducing workers' risks to bloodborne diseases. PMID:10435547

  18. Application of the Alara principle to the occupationally exposed workers in nuclear power plants

    International Nuclear Information System (INIS)

    This report sets down how the Alara (as low as reasonably achievable) principle is applied in radiation protection of the occupationally exposed personnel at light-water reactors in EC countries. In some instances the practices, experiences and results from EC countries are supplemented by the practice in other States (e.g. USA, Sweden). Commencing with a short summary of the legal situation in the Member States of the European Community with regard to Alara, the report describes the framework in which the optimization practice has been developed. The main chapters elaborate in detail how the Alara principle has been put into practice in design and operation in LWRs. The importance of qualification and training of power-plant personnel in relation to optimization of radiation protection is considered and some comparisons are drawn with the US practice. Recommendations are made where reason for modification or harmonization of practices is seen in the conclusions of the different chapters and the overall conclusions and summary of the report

    Full Text Available Abstract Background There is growing evidence that informal payments for health care are fairly common in many low- and middle-income countries. Informal payments are reported to have a negative consequence on equity and quality of care; it has been suggested, however, that they may contribute to health worker motivation and retention. Given the significance of motivation and retention issues in human resources for health, a better understanding of the relationships between the two phenomena is needed. This study attempts to assess whether and in what ways informal payments occur in Kibaha, Tanzania. Moreover, it aims to assess how informal earnings might help boost health worker motivation and retention. Methods Nine focus groups were conducted in three health facilities of different levels in the health system. In total, 64 health workers participated in the focus group discussions (81% female, 19% male and where possible, focus groups were divided by cadre. All data were processed and analysed by means of the NVivo software package. Results The use of informal payments in the study area was confirmed by this study. Furthermore, a negative relationship between informal payments and job satisfaction and better motivation is suggested. Participants mentioned that they felt enslaved by patients as a result of being bribed and this resulted in loss of self-esteem. Furthermore, fear of detection was a main demotivating factor. These factors seem to counterbalance the positive effect of financial incentives. Moreover, informal payments were not found to be related to retention of health workers in the public health system. Other factors such as job security seemed to be more relevant for retention. Conclusion This study suggests that the practice of informal payments contributes to the general demotivation of health workers and negatively affects access to health care services and quality of the health system. Policy action is needed that not only

    Full Text Available The aim of the study was to examine the association between polymorphisms of DNA repair genes and chromosomal damage of 1,3-butadiene- (BD- exposed workers. The study was conducted in 45 pairs of occupationally exposed workers in a BD product workshop and matched control workers in an administrative office and a circulatory water workshop in China. Newly developed biomarkers (micronuclei, MNi; nucleoplasmic bridges, NPBs; nuclear buds, NBUDs in the cytokinesis-blocked micronucleus (CBMN cytome assay were adopted to detect chromosomal damage. PCR and PCR-restriction fragment length polymorphism (RFLP are adopted to analyze polymorphisms of DNA repair genes, such as X-ray repair cross-complementing Group 1 (XRCC1, O6-methylguanine-DNA methyltransferase (MGMT, poly (adenosine diphosphate-ribose polymerases (ADPRT, and apurinic/apyrimidinic endonucleases (APE1. The BD-exposed workers exhibited increased frequencies of MNi and NPBs when compared to subjects in the control group. The results also show that the BD-exposed workers carrying XRCC1 diplotypes TCGA-CCGG (4.25±2.06‰ (FR=2.10, 95% CI: 1.03–4.28 and TCGG-TCGA (5.80±3.56‰ (FR=2.75, 95% CI: 0.76–2.65 had statistically higher NBUD frequencies than those who carried diplotype TCGG-TCGG (1.89±1.27‰. Our study suggests that polymorphisms of XRCC1 gene may influence chromosomal damage in BD-exposed workers.

    Full Text Available It is estimated that Haiti has the highest incidence of cervical cancer in the Western Hemisphere. There are currently no sustainable and affordable cervical cancer screening programs in Haiti. The current status of screening services and knowledge of health care professionals was assessed through a Knowledge, Attitudes, and Practices survey on cervical cancer screening and prevention. It was distributed to Project Medishare for Haiti health care workers (n = 27 in the Central Plateau. The majority (22/27 of participants stated pre-cancerous cells could be detected through screening, however, only four had ever performed a pap smear. All of the participants felt a screening program should be started in their area. Our data establishes that knowledge is fairly lacking among healthcare workers and there is an opportunity to train them in simple, cost effective “screen-and-treat” programs that could have a great impact on the overall health of the population.

Our data establishes that knowledge is fairly lacking among healthcare workers and there is an opportunity to train them in simple, cost effective "screen-and-treat" programs that could have a great impact on the overall health of the population.

    The objectives of the study were to profile occupational injury patterns across home health and hospice care (HHC), organization characteristics, and home health aides' (HHAs) individual characteristics, and examine how worker training affects HHAs' risk of reporting an injury using the model of human factors of health care in the home. The authors measured training knowledge using an 11-item scale and conducted univariate and bivariate analyses to describe injury patterns across individual, occupational, and organizational factors using STATA 12.0. The researchers found that work-related injuries and type of injury were associated with increased likelihood of reporting one or more injuries, full-time employment, high hourly pay, and working in an inpatient or mixed setting. Overall, HHAs perceived that they received "excellent" and "good" training on key topics that promoted safety and job knowledge. Furthermore, the results suggested linkages between worker's complex personal, occupational, and organizational characteristics. PMID:27026275

    Full Text Available The aim of this study is to establish changes in leg volumes in healthy subjects (HS after prolonged standing and prolonged lying. The study was carried out on two HS groups: the group A (20 subjects included physicians and nurses who underwent a water plethysmography test, before and after eight hours of standing still in the operating room. The group B (20 subjects included volunteers who were assessed before and after 10 h of supine resting. Group A: baseline leg volume was 1857.5 mL±196.9 on the right and 1850 mL±194.7 on the left limb. After eight hours of hydrostatic pressure action the two lower limbs volume was significantly increased to 1945 mL±209.6, and to 1940 mL±216.2, respectively (P<0.0001. The increased volume is significantly correlated with time (R2=0.95, P<0.0001. Group B: baseline leg volume was 1875 mL±175.1 on the right, and 1862.5 mL±166.9 on the left limb. After ten hours of resting supine the volume was 1770 mL±195.6, and to 1757.5 mL±194.2, respectively (P<0.0001. The decreased volume is significantly but inverted correlated with time (R2=−0.98, P<0.0001. This study demonstrates how the hydrostatic pressure is a main determinant for fluid accumulation in the lower extremity. To counteract the gravitational gradient becomes the mandatory prophylactic approach for healthy individuals who are exposed to an increased chronic venous disease risk.

    Background: One of the consequences of migration is cultural diversity in various communities. This has created challenges for healthcare systems. Objectives: The aim of this study is to explore the health care staffs’ experience of caring for Immigrants in Mashhad- Iran. Setting: This study is done in Tollab area (wherein most immigrants live) of Mashhad. Clinics and hospitals that immigrants had more referral were selected. Participants: Data were collected through in-depth interviews with medical and nursing staffs. 15 participants (7 Doctors and 8 Nurses) who worked in the more referred immigrants’ clinics and hospitals were entered to the study. Design: This is a qualitative study with content analysis approach. Sampling method was purposive. The accuracy and consistency of data were confirmed. Interviews were conducted until no new data were emerged. Data were analyzed by using latent qualitative content analysis. Results: The data analysis consisted of four main categories; (1) communication barrier, (2) irregular follow- up, (3) lack of trust, (4) cultural- personal trait. Conclusion: Result revealed that health workers are confronting with some trans- cultural issues in caring of immigrants. Some of these issues are related to immigration status and some related to cultural difference between health workers and immigrants. These issues indicate that there is transcultural care challenges in care of immigrants among health workers. Due to the fact that Iran is the context of various cultures, it is necessary to consider the transcultural care in medical staffs. The study indicates that training and development in the area of cultural competence is necessary. PMID:26925887

    An EDF worker potentially exposed to high-intensity 50 Hz magnetic fields had a cardiac defibrillator implanted. Theoretically its operation could be disturbed by magnetic field exposure at work. We use this case study to present an approach to evaluating work safety and the worker's fitness in such situations. The protocol consisted of measuring the magnetic field at the different places where the worker performed his job duties, in his presence, and simultaneously monitoring the operation of the device. The Medtronic device was programmed in bipolar mode. Throughout the workplace, the maximal magnetic field intensity measured at the device level was 650 {mu}T. No dysfunction was recorded in bipolar mode. Following these measurements and device controls, the worker was declared fit and resumed his previous job. Two years later, no incident has been reported. (authors)

    This study evaluated T cell immune responses to purified protein derivative (PPD) and Mycobacterium tuberculosis (Mtb) in health care workers who remained free of active tuberculosis (HCWs w/o TB), health care workers who went on to develop active TB (HCWs w/TB), non-health care workers who were TB free (Non-HCWs) and tuberculosis patients presenting with minimal (Min TB) or advanced (Adv TB) disease. Peripheral blood mononuclear cells (PBMC) were stimulated with Mtb and PPD and the expression of T cell activation markers CD25+ and HLA-DR+, intracellular IL-4 and IFN-gamma production and cytotoxic responses were evaluated. PBMC from HCWs who developed TB showed decreased percentages of cells expressing CD8+CD25+ in comparison to HCWs who remained healthy. HCWs who developed TB showed increased gammadelta TCR+ cell cytotoxicity and decreased CD3+gammadelta TCR- cell cytotoxicity in comparison to HCWs who remained healthy. PBMC from TB patients with advanced disease showed decreased percentages of CD25+CD4+ and CD25+CD8+ T cells that were associated with increased IL-4 production in CD8+ and gammadelta TCR+ phenotypes, in comparison with TB patients presenting minimal disease. TB patients with advanced disease showed increased gammadelta TCR+ cytotoxicity and reduced CD3+gammadelta TCR- cell cytotoxicity. Our results suggest that HCWs who developed TB show an early compensatory mechanism involving an increase in lytic responses of gammadelta TCR+ cells which did not prevent TB. PMID:15708307

    Full Text Available Background: Hepatitis B is a major infectious risk factor for health-care workers (HCWs and public- safety workers. Although seroconversion rate following hepatitis B vaccination is estimated to be more than 90%, serologic response to Heberbiovac HB vaccine currently given in our center in Kermanshah province has been varied in different experiences, So, this study was conducted to determine serologic response in HCWs. Methods: In a descriptive-cross sectional study, in 138 HbcAb from 10 health care centers, HbcAb negatives and vaccinated with Heberbiovac HB (Cuba made, available vaccine in Iran, HbsAb titer was assessed by ELISA. Serologic response as antibody titer equal or more than 10mIU/ml considered protective level (serologic responder. The data were analyzed by SPSS software, using X² and Fisher exact test. Results: Within 138 HCWs(60.1% female and 39.9% male, 69.6% had serologic response. The age had significant role in serologic response rate, but sex, weight, smoking and interval from the last time of vaccine reception were not effective factors. Conclusion: Serologic response rate to HBV vaccine in Kermanshah was much lower than other experiences. We need more information about the efficacy of Heberbiovac HB in high-risk groups and general population, the reasons of low efficacy and increasing serologic response.

  18. Seroprevalence of hepatitis B and hepatitis C in health care workers in abbottabad

    International Nuclear Information System (INIS)

    Hepatitis B and C viruses (HBV and HCV) are hepatotropic viruses causing viral hepatitis, chronic liver disease and hepatocellular carcinoma. Modes of infection are more or less similar. HBV is vaccine preventable while HCV is not. They are prevalent in different parts of the world including Pakistan. The rate of prevalence varies from region to region and among different population segments. The present study was planned to see the prevalence of HBV and HVC among health care workers in various hospitals of Abbottabad. The study was conducted at the District Headquarter Teaching Hospital Abbottabad over a period of one year on 125 health care workers of different categories and either sex. Brief history was taken from each individual and physical examination was performed. Blood samples were taken for HBV and HC serology. Positive sera were confirmed by 3rd generation ELISA. As much as 8% individuals were positive for HBV or HCV. HBV alone was seen in 3 out of 10 (30%) individuals. HCV alone was also found in 3 out of 10 (30%) individuals. HBV and HCV co-infection was seen in 4 out of 10 (40%) individuals. Dental procedures, needle prick and surgical procedures were found the common risk factors. Blood transfusion was known in 2 out of 10 (20%) individuals. Family history of hepatitis was not positive in any individual. Results of the present study differ from those of the previous studies conducted on health care workers in Pakistan. (author)

    We examined the association of gene expression with noncancer chronic disease outcomes in Mayak nuclear weapons plant workers who were exposed to radiation due to their occupation. We conducted a cross-sectional study with selection based on radiation exposure status of Mayak plant workers living in Ozyorsk who were alive in 2011 and either exposed to: combined incorporated Plutonium-239 ((239)Pu) and external gamma-ray exposure (n = 82); external gamma-ray exposure alone (n = 18); or were unexposed (n = 50) of Ozyorsk residents who provided community-based professional support for plant personnel and who were alive in 2011. Peripheral blood was taken and RNA was isolated and then converted into cDNA and stored at -20°C. In a previous analysis we screened the whole genome for radiation-associated candidate genes, and validated 15 mRNAs and 15 microRNAs using qRT-PCR. In the current analysis we examined the association of these genes with 15 different chronic diseases on 92 samples (47 males, 45 females). We examined the radiation-to-gene and gene-to-disease associations in statistical models stratified by gender and separately for each disease and exposure. We modeled radiation exposure as gamma or (239)Pu on both the continuous and categorical scales. Unconditional logistic regression was used to calculate odds ratios (OR), 95% confidence intervals (CI), and the concordance for genes that were significantly associated with radiation exposure and a specific disease outcome were identified. Altogether 12 mRNAs and 9 microRNAs appeared to be significantly associated with 6 diseases, including thyroid diseases (3 genes, OR: 1.2-5.1, concordance: 71-78%), atherosclerotic diseases (4 genes, OR: 2.5-10, concordance: 70-75%), kidney diseases (6 genes, OR: 1.3-8.6, concordance: 69-85%), cholelithiasis (3 genes, OR: 0.2-0.3, concordance: 74-75%), benign tumors [1 gene (AGAP4), OR: 3.7, concordance: 81%] and chronic radiation syndrome (4 genes, OR: 2.5-4.3, concordance: 70

  1. Improving the quality of workers' compensation health care delivery: the Washington State Occupational Health Services Project.

    2001-01-01

    This article has summarized research and policy activities undertaken in Washington State over the past several years to identify the key problems that result in poor quality and excessive disability among injured workers, and the types of system and delivery changes that could best address these problems in order to improve the quality of occupational health care provided through the workers' compensation system. Our investigations have consistently pointed to the lack of coordination and integration of occupational health services as having major adverse effects on quality and health outcomes for workers' compensation. The Managed Care Pilot Project, a delivery system intervention, focused on making changes in how care is organized and delivered to injured workers. That project demonstrated robust improvements in disability reduction; however, worker satisfaction suffered. Our current quality improvement initiative, developed through the Occupational Health Services Project, synthesizes what was learned from the MCP and other pilot studies to make delivery system improvements. This initiative seeks to develop provider incentives and clinical management processes that will improve outcomes and reduce the burden of disability on injured workers. Fundamental to this approach are simultaneously preserving workers' right to choose their own physician and maintaining flexibility in the provision of individualized care based on clinical need and progress. The OHS project then will be a "real world" test to determine if aligning provider incentives and giving physicians the tools they need to optimize occupational health delivery can demonstrate sustainable reduction in disability and improvements in patient and employer satisfaction. Critical to the success of this initiative will be our ability to: (1) enhance the occupational health care management skills and expertise of physicians who treat injured workers by establishing community-based Centers of Occupational

    Full Text Available Abstract Background Although international scientific research on health issues has been dealing with the problem of aggression and violence towards those employed in health care, research activities in Germany are still at an early stage. In view of this, the aim of this study was to examine the frequency and consequences of aggressive behaviour towards nurses and health care workers in different health sectors in Germany and to assess the need for preventive measures. Methods We conducted a cross-sectional retrospective survey. Nurses and health care workers from two nursing homes, a psychiatric clinic and a workshop for people with disabilities were interviewed using a standardised questionnaire. The sample covered 123 individuals (response rate 38.8%. The survey assessed the frequency, the type and the consequences of aggressive behaviour, and social support in connection with coping with aggression in the workplace. Odds ratios (OR and 95% confidence intervals (CI for putative risk factors which may influence the stress induced by aggression at the workplace were calculated using conditional logistic regression. Results During the previous twelve months 70.7% of the respondents experienced physical and 89.4% verbal aggression. Physical aggression more frequently occurred in nursing homes (83.9% of the employees and verbal aggression was more common in the psychiatric clinic (96.7% of the employees. The proportion of the individuals affected in the workshop for people with disabilities was lower (41.9% and 77.4% respectively. The incidents impaired the physical (55% and emotional well-being (77.2% of the employees. The frequency of incidents (weekly: OR 2.7; 95% CI 1.1-6.4 combined with the lack of social support (OR 2.8; 95% CI 1.2-6.6 increased the probability of higher stress due to aggression.

    Full Text Available Introduction: Bauxite ore is a major source of aluminum (Al which contains approximately 35–60% Al by weight. Occupational and environmental bauxite dust exposure may cause toxicity by interaction with human biological systems resulting in oxidative stress (OS and cell death. A neopterin derivative as an antioxidant is able to modulate cytotoxicity by the induction of OS. Materials and Methods: A total of 273 subjects were selected for blood collection from three different major Al producing bauxite mines and were categorized into three groups as experimental (Exp (n = 150, experimental controls (ExC (n = 73 and control (Con (n = 50. Whole blood and serum samples were used for measurement of Al, neopterin, urea and creatinine values. Statistical analysis was performed using R-2.15.1 programming language. Results and Discussion: The result showed that age, body mass index and the behavioral habits, that is, smoking, tobacco and alcohol consumption have possible effects on neopterin level. Serum neopterin levels were found to be significantly higher (P <0.0001 in the experimental group as compared to other groups. Significantly positive correlation (P < 0.0001 was observed between neopterin and creatinine. It was also observed that neopterin level increases as the duration of exposure increases. Conclusion: On the basis of findings it was concluded that exposure to bauxite dust (even at low levels of Al changes biochemical profile leading to high levels of serum neopterin. Levels of serum neopterin in workers exposed to bauxite dust were probably examined for the 1st time in India. The outcome of this study suggested that serum neopterin may be used as potential biomarker for early detection of health risks associated with bauxite dust exposed population.

    Emotional labour increases among long-term care workers because providing care and services to impaired elders causes conflicting interpersonal emotions. Thus, we investigated the associations between emotional labour, general health and job satisfaction among long-term care workers. We conducted a cross-sectional study among 132 established, private day care centres in Tokyo using a mail survey. The outcome variables included two health-related variables and four job satisfaction variables: physical and psychological health, satisfaction with wages, interpersonal relationships, work environment and job satisfaction. We performed multiple regression analyses to identify significant factors. Directors from 36 facilities agreed to participate. A total of 123 responses from long-term care workers were analysed. Greater emotional dissonance was associated with better physical and psychological health and worse work environment satisfaction (partial regression coefficient: -2.93, p = .0389; -3.32, p = .0299; -1.92, p = .0314, respectively). Fewer negative emotions were associated with more job satisfaction (partial regression coefficient: -1.87, p = .0163). We found that emotional labour was significantly inversely associated with health and job satisfaction. Our findings indicated that the emotional labour of long-term care workers has a negative and positive influence on health and workplace satisfaction, and suggests that care quality and stable employment among long-term care workers might affect their emotional labour. Therefore, we think a programme to support emotional labour among long-term care workers in an organized manner and a self-care programme to educate workers regarding emotional labour would be beneficial.

    The study examines possible persisting effects on the peripheral nervous system and visual system in tunnel workers previously exposed to acrylamide and N-methylolacrylamide during grouting work. We compared neurophysiological function in 44 tunnel workers previously exposed during grouting operations (2-10 years post exposure), with 49 tunnel workers with no history of exposure to acrylamide. Nerve conduction velocities (NCV), distal delay, F-response and amplitude in median and ulnar nerves of the right arm, peroneal, sural and tibial nerves of the right leg, visual evoked response (VER) and electroretinography (ERG) were measured. VER and ERG were also performed in 24 subjects more recently exposed to acrylamide grout (16 months post exposure). Exposure to acrylamide containing grouts was assessed by questionnaires. A statistically significant reduction in the mean sensory NCV of the sural nerve (p=0.005), as well as a non-significant reduction of sural amplitude was found in the previously exposed group compared to the control group. VER latencies to the onset of the occipital potential (N75) were prolonged in both exposed groups compared to the control group (pgrouting operations. PMID:18353610

    This study assessed the effects of a person-centered care-based psycho-educational intervention on direct care workers' communicative behaviors with people with dementia living in aged-care facilities. An experimental study with a pretest-posttest control-group design was conducted in four aged-care facilities. Two experimental facilities received an 8-week psycho-educational intervention aiming to develop workers' knowledge about dementia, person-centered care competences, and tools for stress management. Control facilities received education only, with no support to deal with stress. In total, 332 morning care sessions, involving 56 direct care workers (female, mean age 44.72 ± 9.02 years), were video-recorded before and 2 weeks after the intervention. The frequency and duration of a list of verbal and nonverbal communicative behaviors were analyzed. Within the experimental group there was a positive change from pre- to posttest on the frequency of all workers' communicative behaviors. Significant treatment effects in favor of the experimental group were obtained for the frequency of inform (p intervention can positively affect direct care workers' communicative behaviors with residents with dementia. Further research is required to determine the extent of the benefits of this approach. PMID:26400182

    Full Text Available Abstract Background The utility of blood reproductive endocrine biomarkers for assessing or estimating semen quality was explored. Methods A cross-sectional study of 47 DDT exposed malaria vector control workers was performed. Tests included blood basal and post gonadotrophin releasing hormone (GnRH, lutenizing hormone (LH, follicle stimulating hormone (FSH, testosterone, sex hormone binding globulin (SHBG, estradiol (E2 and inhibin; a questionnaire (demographics and general medical history; a physical examination and semen analysis. Semen parameters were determined using either/or or both WHO or the strict Tygerberg criteria. Relationships between semen parameters and endocrine measures were adjusted for age, duration of abstinence before sampling, presence of physical abnormalities and fever in the last two months. All relationships between specific endocrine hormones were adjusted for age and basal SHBG. Results Multiple logistic regression showed a consistent positive relationship (prevalence odds ratio (POR = 8.2, CI:1.4–49.2 between low basal inhibin ( POR 50 pg/ml and abnormal morphology (proportion Conclusion The study has demonstrated that low basal inhibin, elevated basal FSH and high basal E2 can serve as markers of impaired semen quality.

    Americans are living longer, but dying after a prolonged period of management of multiple chronic illnesses and functional disabilities. Despite waves of public and professional activity targeted toward improving care for the dying and supporting the families, gaps in care and challenges in end-of-life care persist. Contentious issues such as the so-called "death panels" or physician payment for discussion of advance directives and care wishes at the end of life; aid in dying; and regarding individuals who actively choose death (case of Brittney Maynard) are continually debated in the public media. Progress toward improvement in the experience of dying remains incremental and change has been slow. With the release of a second Institute of Medicine ( 2014 ) report devoted to what it means to die in America in the 21st century, momentum and opportunity for change may increase. If this is to happen, social workers will need to deliver the range of biopsychosocial care that patients and families so desperately need. However, holistic care of the individual will only improve, if the nation also addresses ongoing systemic problems in financing, policy, and service delivery in end-of-life care. PMID:27462948

    Internal exposure from naturally occurring radionuclides (including the inhaled long-lived actinides (232)Th and (238)U) is a component of the ubiquitous background radiation dose (National Council on Radiation Protection and Measurements. Ionizing radiation exposure of the population of the United States; NCRP Report No. 160; NCRP: Bethesda, MD, 2009). It is of interest to compare the concentration distribution of these natural alpha-emitters in the lungs and respiratory lymph nodes with those resulting from occupational exposure, including exposure to anthropogenic plutonium and depleted and enriched uranium. This study examines the application of laser ablation-inductively coupled plasma-mass spectrometry (LA-ICPMS) to quantifying and visualizing the mass distribution of uranium and thorium isotopes from both occupational and natural background exposure in human respiratory tissues and, for the first time, extends this application to the direct imaging of plutonium isotopes. Sections of lymphatic and lung tissues taken from deceased former nuclear workers with a known history of occupational exposure to specific actinide elements (uranium, plutonium, or americium) were analyzed by LA-ICPMS. Using a previously developed LA-ICPMS protocol for elemental bio-imaging of trace elements in human tissue and a new software tool, we generated images of thorium ((232)Th), uranium ((235)U and (238)U), and plutonium ((239)Pu and (240)Pu) mass distributions in sections of tissue. We used a laboratory-produced matrix-matched standard to quantify the (232)Th, (235)U, and (238)U concentrations. The plutonium isotopes (239)Pu and (240)Pu were detected by LA-ICPMS in 65 mum diameter localized regions of both a paratracheal lymph node and a sample of lung tissue from a person who was occupationally exposed to refractory plutonium (plutonium dioxide). The average (overall) (239)Pu concentration in the lymph node was 39.2 ng/g, measured by high purity germanium (HPGe) gamma

    2013-05-01

    This study aimed to improve communication and care provision in five home or long term care settings by raising staff awareness about health beliefs and patterns among varied cultures. Lack of cultural competence is linked to ethnocentric attitudes that can lead to inappropriate communication and ineffective interventions. Understanding the culturally imbedded belief systems of patients and providers is an integral part of effective communication skills that are foundational to optimal team functioning. Participants included five home or long term care agencies in an underserved region of New England. Seventy-four nurses, aids and allied health professionals participated in 10-12 small group interactive sessions. Comparison of pre and post cultural self efficacy scores revealed that participant confidence regarding their knowledge and skills when interacting with other cultures improved interactions with patients and co-workers. Journal exemplars supported the ability of attendees to apply content to the workplace. PMID:23265680

    Results: This cross sectional prospective study was conducted in the Department of Obstetrics and Gynecology Govt. Medical College Srinagar from January to June 2015. 150 health care professionals were taken for the study. Knowledge regarding disease and transmission was fairly good. Regarding vaccination status 42.02% of medical and 29.60% of paramedical staff was fully vaccinated, the most common reason for non compliance being ignorance of importance of vaccination. Awareness of patients' vaccination status was also low. Conclusions: Due to low vaccine-compliance, Health care workers (HCW continue to be at the risk of occupational HBV infection. Regular Health education highlighting occupational risk of HBV, accessibility of vaccine, and mandatory vaccination of HCW is recommended to prevent Hepatitis B infection.

    Of the 175 million people (2.9% of the world's population) living outside their country of birth in 2000, 65 million were economically active. The rise in the number of people migrating is significant for many developing countries because they are losing their better-educated nationals to richer countries. Medical practitioners and nurses represent a small proportion of the highly skilled workers who migrate, but the loss for developing countries of human resources in the health sector may mean that the capacity of the health system to deliver health care equitably is significantly compromised. It is unlikely that migration will stop given the advances in global communications and the development of global labour markets in some fields, which now include nursing. The aim of this paper is to examine some key issues related to the international migration of health workers and to discuss strategic approaches to managing migration. PMID:15375449

    This article compares hospital managers' (HM), unit managers' (UM), and health care workers' (HCW) perceptions of respiratory protection safety climate in acute care hospitals. The article is based on survey responses from 215 HMs, 245 UMs, and 1,105 HCWs employed by 98 acute care hospitals in six states. Ten survey questions assessed five of the key dimensions of safety climate commonly identified in the literature: managerial commitment to safety, management feedback on safety procedures, coworkers' safety norms, worker involvement, and worker safety training. Clinically and statistically significant differences were found across the three respondent types. HCWs had less positive perceptions of management commitment, worker involvement, and safety training aspects of safety climate than HMs and UMs. UMs had more positive perceptions of management's supervision of HCWs' respiratory protection practices. Implications for practice improvements indicate the need for frontline HCWs' inclusion in efforts to reduce safety climate barriers and better support effective respiratory protection programs and daily health protection practices.

    Full Text Available Background: Fast urbanization trends, rapid industrial growth, globalization, and poor environmental conditions at work places have created a lot of healthrelated issues. Aim and Objectives: The aim of this study is to investigate Peak Expiratory Flow Rate (PEFR as the assessment of lung function in occupationally exposed petrol pump workers and also check whether PEFR increases or decreases with duration of exposure. Material and Methods: The study was conducted on 60 male petrol pump workers between age group of 20-40 years who were working as petrol filling attendants for more than one year from western Maharashtra. 50 normal healthy males with same socioeconomic status were chosen as controls to find out the effect of occupational exposure to petroleum product on PEFR as the assessment of lung function tests. Petrol pump workers were divided into three groups based on their duration of exposure i.e. 1- 5 yrs, 6- 10 yrs and more than 11 years. PEFR of petrol pump workers and control was measured by using a Mini Wright peak flow meter which is a portable device for measuring ventilator functions. Comparisons was done using unpaired t-test for 2 groups comparisons and one way ANOVAfor multiple groups of exposures. Results: The PEFR was significantly lower decrease (p=0.001 around petrol pump workers (389.17 as compared to control (534.2. As year of exposure increased mean value of PEFR was significantly decreased from 452.17, 378.00 and 283.64 respectively in petrol pump workers. Conclusion: The results suggested that respiratory functions i.e. PEFR of occupationally exposed petrol pump workers are significantly reduced as compared to controls, also PEFR is significantly reduced with increase in the duration of exposure.

  19. The free health care initiative: how has it affected health workers in Sierra Leone?

    There is an acknowledged gap in the literature on the impact of fee exemption policies on health staff, and, conversely, the implications of staffing for fee exemption. This article draws from five research tools used to analyse changing health worker policies and incentives in post-war Sierra Leone to document the effects of the Free Health Care Initiative (FHCI) of 2010 on health workers.Data were collected through document review (57 documents fully reviewed, published and grey); key informant interviews (23 with government, donors, NGO staff and consultants); analysis of human resource data held by the MoHS; in-depth interviews with health workers (23 doctors, nurses, mid-wives and community health officers); and a health worker survey (312 participants, including all main cadres). The article traces the HR reforms which were triggered by the FHCI and evidence of their effects, which include substantial increases in number and pay (particularly for higher cadres), as well as a reported reduction in absenteeism and attrition, and an increase (at least for some areas, where data is available) in outputs per health worker. The findings highlight how a flagship policy, combined with high profile support and financial and technical resources, can galvanize systemic changes. In this regard, the story of Sierra Leone differs from many countries introducing fee exemptions, where fee exemption has been a stand-alone programme, unconnected to wider health system reforms. The challenge will be sustaining the momentum and the attention to delivering results as the FHCI ceases to be an initiative and becomes just 'business as normal'. The health system in Sierra Leone was fragile and conflict-affected prior to the FHCI and still faces significant challenges, both in human resources for health and more widely, as vividly evidenced by the current Ebola crisis.

    "Occupational MDR-TB"  …  "XDR-TB"  …  "Treatment-induced hearing loss": 3 life-changing messages imparted over the phone. Three personal accounts are shared highlighting the false belief held by many healthcare workers (HCWs) and students in low-resource settings-that they are immune to tuberculosis despite high levels of occupational tuberculosis exposure. This misconception reflects a lack of awareness of tuberculosis transmission and disease risk, compounded by the absence of accurate occupational tuberculosis estimates. As the global problem of drug-resistant (DR) tuberculosis evolves, HCWs are increasingly infected and suffer considerable morbidity and mortality from occupational DR tuberculosis disease. Similarly, healthcare students are emerging as a vulnerable and unprotected group. There is an urgent need for improved detection, vaccines, preventive therapy, treatment, and support for affected HCWs and those they care for, as well as destigmatization of all forms of tuberculosis. Finally, efforts to protect HCWs and prevent DR tuberculosis transmission by universal implementation of tuberculosis infection control measures should be prioritized. PMID:27118858

    Greece has been seriously affected by the economic crisis. In 2011 there were reports of 40% reduction to public hospital budgets. Occasional shortages of medical supplies have been reported in mass media. We attempted to pivotally investigate the frequency of medical supplies shortages in two Greek hospital units of the National Health System and to also assess their possible impact on burnout risk of health care workers. We conducted a cross-sectional study (n=303) of health care workers in two Greek hospitals who were present at the workplace during a casually selected working day (morning shift work). The Maslach Burnout Inventory (MBI) was used as the measure of burnout. An additional questionnaire was used about demographics, and working conditions (duration of employment, cumulative night shifts, type of hospital including medical supplies shortages and their impact on quality of healthcare. The prevalence of emotional exhaustion, depersonalization and low personal accomplishment was 44.5%, 43.2% and 51.5%, respectively. Medical supply shortages were significantly associated with emotional exhaustion and depersonalization. This finding provides preliminary evidence that austerity has affected health care in Greece. Moreover, the medical supply shortages in Greek hospitals may reflect the unfolding humanitarian crisis of the country. PMID:24688306

    There is a more and more emerging consensus claiming universal access to health care in order to achieve the desired Millennium Development Goals related to health in Africa. Unfortunately, the debate of the universal coverage has focussed so far mainly on financial affordability, while it is also a human resource matter. Many countries in sub-Saharan Africa are experiencing severe shortages of skilled health care workers. There are several causes, the importance of which varies by country, but one of the most significant factors is brain drain. In those countries, scarcity of doctors increases the distance between a doctor and patients, and bridging that increased distance implies costs, both time and money. Adequate number of qualified health personnel is then vital to increase coverage and improve the quality of care. In as much as access to health services is also determined by access to qualified health workers, any reflection on the universal health coverage has to also consider the inequities in qualified health personnel distribution throughout the world.

    1999-11-01

    This paper reports on research into the practice of euthanasia amongst Australian health care professionals specializing in HIV/AIDS. It draws on data from thirty-nine semi-structured interviews carried out in Sydney, Melbourne, Brisbane and Canberra with physicians, general practitioners, hospital and community nurses, therapists and community workers. Using a qualitative methodology, the study seeks to identify how (illegal) euthanasia is currently practised, the degrees of involvement, the various forms that involvement takes, and the social relations which provide the context for involvement. In this paper we outline three categories of 'doers' to illustrate the range of attitudes and practices concerning euthanasia. This 'typology' carries a number of implications for recent policy debates over the legalisation of euthanasia. In particular it illustrates, at least within the context of AIDS care, the fragmentation of consensus over euthanasia amongst health care workers, the reality of current illegal euthanasia practices, and the limitations of a prohibitionist policy. While the legalisation of euthanasia within a regulatory framework is sometimes portrayed as an extreme or 'radical' response to terminal illness, the data presented in this paper suggest that prohibitionism is also radical in its failure to control euthanasia practice.

    Full Text Available Immune responses to hepatitis B virus (HBV vaccine in six low- or non-responded health-care workers were tested with an intradermal low dose (5 micrograms of the recombinant vaccine. The injection was repeated three or four times at fortnightly intervals. These successive doses of the vaccine induced a high concentration of antibodies with delayed-type hypersensitivity (DTH skin reactions in all six subjects. A few minor temporary side effects, such as irritation and itching at the injection site, were reported by some of the vaccinees. The results suggest low-dose of intradermal HBV vaccinations for low- or non-responders are safe and readily effective.

    Quality of exposure assessment has been shown to be related to the ability to detect risk of lymphohematopoietic disorders in epidemiological investigations of benzene, especially at low levels of exposure. We set out to build a statistical model for reconstructing exposure levels for 2898 subjects from 501 factories that were part of a nested case-cohort study within the NCI-CAPM cohort of more than 110,000 workers. We used a hierarchical model to allow for clustering of measurements by factory, workshop, job, and date. To calibrate the model we used historical routine monitoring data. Measurements below the limit of detection were accommodated by constructing a censored data likelihood. Potential non-linear and industry-specific time-trends and predictor effects were incorporated using regression splines and random effects. A partial validation of predicted exposures in 2004/2005 was performed through comparison with full-shift measurements from an exposure survey in facilities that were still open. Median cumulative exposure to benzene at age 50 for subjects that ever held an exposed job (n=1175) was 509 mg/m(3) years. Direct comparison of model estimates with measured full-shift personal exposure in the 2004/2005 survey showed moderate correlation and a potential downward bias at low (<1 mg/m(3)) exposure estimates. The modeling framework enabled us to deal with the data complexities generally found in studies using historical exposure data in a comprehensive way and we therefore expect to be able to investigate effects at relatively low exposure levels.

    This study examined social workers' roles in caring for low-income elders with advanced chronic disease in an innovative, community-based managed care program, from the perspective of elders, family, team members, and social workers. The results are drawn from a larger longitudinal, multimethod case study. Sources of data include survey reports of needs addressed by social workers for 120 deceased elders, five focus groups with interdisciplinary team members, and in-depth interviews with 14 elders and 10 of their family caregivers. A thematic conceptual matrix was developed to detail 32 distinctive social work roles that address divergent needs of elders, family, and team members. Distinctive perceptions of social workers' roles were identified for the different stakeholder groups (i.e., elders, family caregivers, team members, and social workers). Findings from this study may inform supervisors and educators regarding training needs of those preparing to enter the rapidly growing workforce of gerontological social workers who may be called upon to care for elders at the end of life. Training is particularly warranted to help social workers gain the skills needed to more successfully treat symptom management, depression, anxiety, agitation, grief, funeral planning, and spiritual needs that are common to the end of life.

    Recently, diesel engine exhaust (DEE) was reclassified as a known carcinogen to humans. DNA methylation alterations in DNA damage response (DDR)-related genes have the potential to affect DEE exposure-related cancer risk. However, the evidence regarding the association between DEE exposure and methylation alterations in DDR-related genes is limited. In 117 DEE-exposed workers and 112 non-DEE-exposed workers, we measured urinary concentrations of six mono-hydroxylated polycyclic aromatic hydrocarbons (OH-PAHs). We also determined the methylation levels of three DDR-related genes (p16, RASSF1A, and MGMT) and LINE-1 by bisulfite-pyrosequencing assay. We found that DEE-exposed workers exhibited significantly lower mean promoter methylation levels of p16, RASSF1A, and MGMT than non-DEE-exposed workers (all p < 0.001). In all study subjects and non-smoking workers, increasing quartiles of urinary summed OH-PAHs was associated with hypomethylation of p16, RASSF1A, and MGMT (all p < 0.05). In non-smoking workers, methylation in p16, RASSF1A, and MGMT decreased by 0.36 % [95 % confidential interval (CI): -0.60, -0.11 %], 0.46 % (95 % CI: -0.79, -0.14 %), and 0.55 % (95 % CI: -0.95, -0.15 %), respectively, in association with highest versus lowest quartile of urinary summed OH-PAHs. In addition, p16, RASSF1A, MGMT, and LINE-1 methylation levels showed negative correlations with cytokinesis-block micronucleus cytome index which was previously measured in the same workers (all p < 0.05). In conclusion, our results clearly indicated that DEE exposure and increased genetic damage were associated with hypomethylation of p16, RASSF1A, and MGMT. Future studies with larger sample size are needed to confirm these associations. PMID:26410583

    Full Text Available We aimed to understand health worker’s perceptions about the nurse’s visibility who works at an intensive care unit. An exploratory descriptive and qualitative research conducted in a large size hospital in the South of Brazil. Participants were physicians, physiotherapists, secretaries and cleaning workers from intensive care units. Data were collected through semi-structured interview and submitted to content analysis, thematic modality. The nurse’s visibility is recognized by articulation in assistive process, subsidized by scientific knowledge and management capability. The lack of institutional support and work overload were pointed by other professionals as limits. The great responsibility given to nurses and overload are unfavorable factors to visibility, yet, scientific knowledge linked to their actions, gives them visibility, credibility, trust and respect from the team.

    Objectives This study assessed the knowledge of recommended urinary catheter care practices among nursing home (NH) healthcare workers (HCWs) in Southeast Michigan. Design A self-administered survey. Setting Seven nursing homes in Southeast Michigan. Participants Three hundred and fifty-six healthcare workers. Methods An anonymous, self-administered survey of HCWs (nurses & nurse aides) in seven NHs in 2006. The survey included questions about respondent characteristics and knowledge about indications, care, and personal hygiene pertaining to urinary catheters. The association of knowledge measures with occupation (nurses vs. aides) was assessed using generalized estimating equations. Results A total of 356 of 440 HCWs (81%) responded. Over 90% of HCWs were aware of measures such as cleaning around the catheter daily, glove use, and hand hygiene with catheter manipulation. They were less aware of research-proven recommendations of not disconnecting the catheter from its bag (59% nurses vs. 30% aides, P < .001), not routinely irrigating the catheter (48% nurses vs. 8% aides, P < .001), and hand hygiene even after casual contact (60% nurses vs. 69% aides, P = .07). HCWs were also unaware of recommendations regarding alcohol-based handrub (27% nurses & 32% aides with correct responses, P = .38). HCWs reported sources, both informal (such as nurse supervisors) and formal (in-services), of knowledge about catheter care. Conclusion Wide discrepancies remain between research-proven recommendations pertaining to urinary catheter care and HCWs' knowledge. Nurses and aides differ in their knowledge of recommendations against harmful practices, such as disconnecting the catheter from the bag and routinely irrigating catheters. Further research should focus on strategies to enhance dissemination of proven infection control practices in NHs. PMID:20662957

    Full Text Available Aims: To assess the health of children of construction workers with the help of anthropometric measurements and to explore their childcare practices. Settings and Design : Female construction workers and their children of age 12 to 36 months were taken as one study unit. The study had two components. One component deals with anthropometric measurements of the children while a qualitative descriptive exploratory component was used to explore mothers' perspectives and childcare practices. Methodology: Anthropometric measurements, background information, and living conditions were collected with the help of pre-tested and semi-structured questionnaire. In depth interview technique was used to explore child care practices. Total 14 mothers were interviewed to attain the saturation of responses. "Snow ball" technique was used to recruit children for anthropometric measurements and mothers for in-depth interview. Anthropometric analysis was done in WHO-ANTHRO software v 3.0.1. Content analysis method was used to analyze emerging themes from the interviews. Results : Mean Z scores of weight for age, height for age, and MUAC was less than –1.5. Among the children, 67.2% of children were underweight; 28.4% were wasted while 49.3% were stunted. All mothers believed breast milk to be good for baby for first few months, but only 11% of mothers could practice exclusive breast-feeding. Mothers' perspectives about childcare shows understanding about importance of breast-feeding, complementary feeding, balanced diet, and vaccination. However, mothers were not able to practice their knowledge in childcare; main reasons were fear of wage loss, unavailability of proper living facilities and influence of labor contractor. Conclusions: The study findings confirm the inequity of health among children of construction workers. Mainstreaming of the workers in unorganized sector and strict legislations ensuring good living conditions are recommended to combat child

    Full Text Available The aim of the study was to analyze epidemiological and microbiological aspects of oral colonization by methicillin-resistant Staphylococcus of health care workers in a cancer hospital. Interview and saliva sampling were performed with 149 health care workers. Antimicrobial resistance was determined by disk diffusion and minimum inhibitory concentration. Polymerase Chain Reaction, Internal Transcribed Spacer-Polymerase Chain Reaction and Pulsed Field Gel Electrophoresis were performed for genotypic characterization of methicillin-resistant Staphylococcus. Risk factors were determined by logistic regression. Methicillin-resistant Staphylococcus colonization prevalence was 19.5%, denture wearing (p = 0.03, habit of nail biting (p = 0.04 and preparation and administration of antimicrobial (p = 0.04 were risk factors identified. All methicillin-resistant Staphylococcus were S. epidermidis, 94.4% of them had mecA gene. Closely related and indistinguishable methicillin-resistant S. epidermidis were detected. These results highlight that HCWs which have contact with patient at high risk for developing infections were identified as colonized by MRSE in the oral cavity, reinforcing this cavity as a reservoir of these bacteria and the risk to themselves and patients safety, because these microorganisms may be spread by coughing and talking.

    Full Text Available Evaluation of HIV-induced IL-2 production by peripheral blood mononuclear cells (PBMC and HIV-specific T helper and cytotoxic T lymphocyte (CTL responses in health care workers (HCW occupationally exposed to HIV reveals a high rate of response to HIV among non-seroconverters. IL-10 is also known to interfere with HIV infection in vitro. To evaluate the induction of IL-10 by HIV antigens in HCW occupationally exposed to HIV, 18 HCW with percutaneous injury were enrolled in this study, 9 of them exposed to HIV-contaminated blood, and 9 exposed to HIV-negative blood. PBMC were incubated on plates coated with HIV-1 antigens, and IL-10 was measured in supernatants by ELISA. Five of nine HCW exposed to HIV-contaminated blood presented HIV-induced IL-10. Two of nine HCW exposed to HIV-negative source patients also had detectable levels of HIV-induced IL-10, one of them in the sample obtained on the day of accidental exposure. There was a relationship between the type of device involved in injury and IL-10 production. Individuals exposed to hollow needles or scalpels presented HIV-induced IL-10, whereas those exposed to solid needles and to digital puncture did not, suggesting a relationship between infectious load and IL-10. Although occupational exposure to HIV leads to a low rate of seroconversion, these individuals can develop an antigen-specific immune response characterized in our study by induction of IL-10 in PBMC in vitro.

    Full Text Available Hepatitis C virus (HCV infection is a major public health in Iran as well as throughout the world. Health care workers (HCW are occupationally at the risk of HCV infection. The aim of this article is to review the information about the epidemiology, nosocomial epidemiology, natural history, immunopathogenesis, and occupational risks associated with managing HCV in the health care workplace. Information obtained from previous investigation on HCV infection has yielded a better knowledge about HCV. Because data demonstrating the efficacy of any intervention are not yet available, no definitive post exposure anti viral therapy can be recommended for HCWs who are occupationally exposed to HCV. Based on existing data, the preemptive therapy and watchful waiting strategies outlined in this review article represent reasonable interim approaches to this complex problem.

    Extremely low frequency electro magnetic fields (EMFs) have been classified as possibly carcinogenic to humans by the International Agency for Research on Cancer. An increased number of chromosomal alterations in peripheral lymphocytes are correlated with elevated incidence of cancer. The aim of the present study was to assess occupationally induced chromosomal damage in EMF workers exposed to low levels of radiation. We used conventional metaphase chromosome aberration (CA) analysis and the micronucleus (MN) assay as biological indicators of non ionizing radiation exposure. In the present study totally 70 subjects were selected including 50 exposed and 20 controls. Informed written consent was obtained from all participants and the study was performed in accordance with the Declaration of Helsinki and the approval of the local ethical committee. A higher degree of CA and MN was observed in exposed subjects compared to controls, the frequency of CA being significantly enhanced with long years of exposure (P<0.05). Moreover increase in CA and MN with age was noted in both exposed subjects and controls, but was significantly greater in the former. The results of this study demonstrated that a significant induction of cytogenetic damage in peripheral lymphocytes of workers occupationally exposed to EMFs in electric transformer and distribution stations. In conclusion, our findings suggest that EMFs possess genotoxic capability, as measured by CA and MN assays; CA analysis appeared more sensitive than other cytogenetic end-points. It can be concluded that chronic occupational exposure to EMFs may lead to an increased risk of genetic damage among electrical workers. PMID:22938490

    2010-05-01

    The purpose of this exploratory study was to understand 'hardiness' as defined and operationalized by senior health executives, and to explore the options for increasing the hardiness of the health-care workforce. Previous research has shown that hardiness is important in the workplace as a means to reduce or avoid the negative impact of stress, which then has an association with the maintenance of individual health. Hardiness has been thought to play an important role in assisting health-care workers deal with emotional and stressful work environments. In depth interviews were conducted with senior managers in a Victorian health service to explore hardiness and determine whether the senior executives had identified hardiness as a factor related to performance, how they recognized it within their staff and how hardiness might be enhanced within the organization. The senior managers were able to identify hardy members of their staff, whom they largely described as high performers. We argue that there is opportunity to strengthen health-care organizations by identifying and supporting hardy staff members. Our findings suggest that health-care organizations can teach the concept of hardiness, select hardy employees and develop strategies to assist employees to increase their levels of hardiness in the workplace.

    Purpose To perform a process evaluation of the implementation of a workplace integrated care intervention for workers with rheumatoid arthritis to maintain and improve work productivity. The intervention consisted of integrated care and a participatory workplace intervention with the aim to make adaptations at the workplace. Methods The implementation of the workplace integrated care intervention was evaluated with the framework of Linnan and Steckler. We used the concepts recruitment, reach, dose delivered, dose received, fidelity and satisfaction with the intervention. Data collection occurred through patient questionnaires and medical records. Results Participants were recruited by sending a letter including a reply card from their own rheumatologist. In total, we invited 1973 patients to participate. We received 1184 reply cards, and of these, 150 patients eventually participated in the study. Integrated care was delivered according to protocol for 46.7 %, while the participatory workplace intervention was delivered for 80.6 %. Dose received was nearly 70 %, which means that participants implemented 70 % of the workplace adaptations proposed during the participatory workplace intervention. The fidelity score for both integrated care and the participatory workplace intervention was sufficient, although communication between members of the multidisciplinary team was limited. Participants were generally satisfied with the intervention. Conclusions This process evaluation shows that our intervention was not entirely implemented as intended. The integrated care was not delivered to enough participants, but for the intervention components that were delivered, the fidelity was good. Communication between members of the multidisciplinary team was limited. However, the participatory workplace intervention was implemented successfully, and participants indicated that they were satisfied with the intervention. PMID:26811171

    Kathryn Elizabeth Lancaster

    Full Text Available The HIV care continuum among female sex workers (FSW, a key population, has not been well characterized, especially within the generalized epidemics of sub-Saharan Africa. This was the first study to characterize the HIV care continuum among FSW in Lilongwe, Malawi.From July through September 2014, we used venue-based sampling to enroll 200 adult FSW in Lilongwe, Malawi into a cross-sectional evaluation assessing HIV care continuum outcomes. Seropositive FSW, identified using HIV rapid testing, received rapid CD4 counts in addition to viral loads using dried blood spots. We calculated proportions of HIV-infected FSW who had history of care, were on ART, and had suppressed viral load and we used Poisson regression to estimate the associations of demographic characteristics and transmission risk behaviors with each outcome.HIV seroprevalence was 69% (n = 138. Among all FSW the median age was 24 years (IQR: 22-28. Among the 20% who were newly diagnosed and reported previously testing negative, the median time since last HIV test was 11 months (interquartile range: 3-17. The majority (69% of HIV-infected FSW had a history of HIV care, 52% reported current ART use, and 45% were virally suppressed. Of the FSW who reported current ART use, 86% were virally suppressed. Transmission risk behaviors were not associated with continuum outcomes.FSW in Lilongwe were predominately young and have a high HIV prevalence. Only half of HIV-infected FSW reported current ART use, but the majority of those on ART were virally suppressed. To reduce ongoing transmission and improve health outcomes, increased HIV testing, care engagement, and ART coverage is urgently needed among FSW. Universal testing and treatment strategies for all FSW in Malawi must be strongly considered.

    Social workers play a key role in the delivery of interdisciplinary health care. However, in the past decade, concerns have been raised about social work's sustainability and contributions in a changing health care sector. These changes come at a time when older patients are more complex and vulnerable than ever before. In this article, using a strengths-based approach, the authors examine the key contributions made by social workers working with older patients with hip fracture as they strive to achieve successful care transitions. Twenty-five interviews with health care professionals (HCPs) were conducted and then analyzed using an analytical coding framework. Although social workers are vital, they are often underused and overlooked in the care of hip fracture patients. The authors sketch the important contributions that social workers make to care transitions after hip fracture, specifically informational continuity; patient-HCP relational continuity; conflict resolution; mediation among family, patient, and HCP (for example, doctors and nurses); collaboration with family caregivers and community supports; and relocation counseling.

    The symptoms of posttraumatic stress disorder and associated risk factors were investigated among health care workers in earthquake-affected areas in southwest China. 343 health care workers completed the Chinese version of the Impact of Event Scale-Revised 3 mo. after the Wenchuan Earthquake. The prevalence of probable PTSD was 19%. The significant risk factors identified for PTSD severity included being female, being bereaved, being injured, and higher intensity of initial fear. These findings suggest that PTSD is a common mental health problem among health care workers in earthquake-affected areas. The present information can be useful in directing, strengthening, and evaluating disaster-related mental health needs and interventions after an earthquake. PMID:20524558

BLLs were assessed by an atomic absorption spectrophotometer. Serum NSE, dopamine and serotonin were measured by ELISA. Neurobehavioral functions were assessed by CDC-recommended tests—simple reaction time (SRT, symbol digit substitution test (SDST, and serial digit learning test (SDLT.Results: There was a significant correlation (r 0.199, p<0.05 between SDST and BLL. SDLT and SRT had also a significant positive correlation (r 0.238, p<0.01. NSE had a negative correlation (r –0.194, p<0.05 with serotonin level. Multiple linear regression analysis revealed that both SRT and SDST had positive significant associations with BLL. SRT also had a positive significant association with age.Conclusion: Serum NSE cannot be used as a marker for BLL. The only domain of neurobehavioral function tests that is affected by increased BLL in workers of lead-acid battery manufacturing process is that of the “attention and perception” (SDST.

    Full Text Available ABSTRACT: Introduction & Objective: Hepatitis B is a common infection in the world and one of the main health problems in our country. Over 350 million people are infected with Hepatitis B virus in the world and are chronic carriers of this infection. Health care workers are at risk of infection with blood born viruses including hepatitis B (HBV. This study was conducted to find out the rate of anti-HBs antibodies among the health-care workers (HCW in Yasuj hospitals, Southwest of Iran. Materials & Methods: This is a cross sectional descriptive study in which 212 staff was randomly selected from different wards of the hospitals in Yasuj. Blood samples were taken from each individual and tested for hepatitis B surface antibody (anti-HBs by ELISA. Those who had anti-HBs titer > 10 IU/ml were considered as positive. Collected data were analyzed by SPSS software using descriptive data analysis and chi-square test. Results: 61.3% of the subjects were female and 38.7% were male. 93.9% of the subjects had a history of one to three doses of hepatitis B vaccination. Results of this study showed that 185 (87.3% of the staff have anti hepatitis B antibodies (Anti-HBs. Among the staff that was negative for anti-HBs antibody, 12 had a history of hepatitis B vaccination (at least one dose. Female employees were more positive than males (93% vs. 78% and this difference was statistically significant (p<0.05. Moreover, a positive correlation was found between the titer of antibody and sex where females had a higher titer of antibody in comparison with males (p<0.05. No correlation was found between the workplace of HCW and positive anti-HBS. Conclusion: Result of this study indicates that more than 85 percent of the health-care workers in Yasuj have reasonable immunity against hepatitis B infection. A small proportion of HCWs had no immunity against HBV. The second course of hepatitis B vaccine should be delivered to those who had no immunity against hepatitis B
