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 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.

    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.

    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

    2013-08-01

    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.

    The results of health questionnaire interviews with 390 electrical power transmission and distribution workers, together with long term estimates of their exposure to 50 Hz electric fields, and short term measurements of the actual exposure for 287 of them are reported. Twenty eight workers received measurable exposures, averaging about 30 kVm-1h over the two week measurement period. Estimated exposure rates were considerably greater, but showed fair correlation with the measurements. Although the general level of health was higher than we have found in manual workers in other industries, there were significant differences in the health measures between different categories of job, different parts of the country, and in association with factors such as overtime, working alone, or frequently changing shift. After allowing for the effects of job and location, however, we found no significant correlations of health with either measured or estimated exposure to electric fields. PMID:3970875

    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.

    Tuberculosis (TB) is a global emergency. Poverty, increasing migration, homelessness and the compulsions to live and work in high-risk environments are making people increasingly susceptible to the disease. Those working in mines, construction work, stone-crushing and in other similar occupations where there is a greater level of exposure to silica dust are specially vulnerable. Though the association between TB and silicosis has been firmly established by the results of epidemiologic studies no attempts have been made to study the epidemiological features of radiologically active TB among free silica exposed workers. Thus the cross sectional study was carried out among slate pencil workers and quartz stone crushers to assess the prevalence of TB and some associated epidemiological factors. It included 253 quartz workers and 102 slate pencil workers. Clinical history and chest radiographs were used for labeling the subjects as tuberculotic. The pulmonary functions of the subjects were measured using Spirovit SP- 10. Statistical analysis was carried out using statistical software package Epi Info 3.3.2. Among stone crushers the prevalence of TB was found to be 10.7% while among slate pencil workers it was as high as 22.5%. Among the quartz stone-crushers the workers aged ≥35 years, those exposed for ≥3 years and those who were smokers had higher risk TB while among the slate pencil workers, only those exposed for ≥10 years had higher risk. Though the FVC and FEV(1) values of the workers having TB were lower than those having normal radiographs, the differences were found to statistically non-significant.

Among the quartz stone-crushers the workers aged ≥35 years, those exposed for ≥3 years and those who were smokers had higher risk TB while among the slate pencil workers, only those exposed for ≥10 years had higher risk. Though the FVC and FEV 1 values of the workers having TB were lower than those having normal radiographs, the differences were found to statistically non-significant.

    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...

  7. Screening and surveillance of workers exposed to mineral dusts

    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.

    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.

    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

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....

  12. 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)

  13. 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.

  14. 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

  15. 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.

  19. 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

    Full Text Available Introduction: The otoacoustic emissions test is an essential tool in the evaluation of auditory function, since it allows the early detection of cochlear damage of occupational origin. Objective: To present a review of the literature and analyze the effectiveness of the clinical application of the otoacoustic emissions test in workers exposed to noise. Methods: A bibliographical search covering a period of 10 years was performed in the Virtual Health Library including published articles in national and international journals indexed in the internationally recognized databases for the health sciences, LILACS, SCIELO, and MEDLINE, using the terms "otoacoustic emissions" and "occupational exposure." The type of published article (national/international, the type and intensity of the stimulus most commonly used for the evoked otoacoustic emissions, the gender and age of the subjects, and the conclusions from the retrospective studies were all taken into consideration. Results and Conclusions: A total of 19 articles were analyzed, 7 national and 12 international, covering subjects from 17 to 77 years of age, mostly men. The type of stimulus most commonly used for the evoked otoacoustic emissions was the distortion method (12. Through this review, we have concluded that testing of evoked otoacoustic emissions in workers exposed to noise is an important tool in the early diagnosis of noise-induced cochlear hearing disorders.

  1. [Calculation of workers' health care costs].

    Rydlewska-Liszkowska, Izabela

    2006-01-01

    In different health care systems, there are different schemes of organization and principles of financing activities aimed at ensuring the working population health and safety. Regardless of the scheme and the range of health care provided, economists strive for rationalization of costs (including their reduction). This applies to both employers who include workers' health care costs into indirect costs of the market product manufacture and health care institutions, which provide health care services. In practice, new methods of setting costs of workers' health care facilitate regular cost control, acquisition of detailed information about costs, and better adjustment of information to planning and control needs in individual health care institutions. For economic institutions and institutions specialized in workers' health care, a traditional cost-effect calculation focused on setting costs of individual products (services) is useful only if costs are relatively low and the output of simple products is not very high. But when products form aggregates of numerous actions like those involved in occupational medicine services, the method of activity based costing (ABC), representing the process approach, is much more useful. According to this approach costs are attributed to the product according to resources used during different activities involved in its production. The calculation of costs proceeds through allocation of all direct costs for specific processes in a given institution. Indirect costs are settled on the basis of resources used during the implementation of individual tasks involved in the process of making a new product. In this method, so called map of processes/actions consisted in the manufactured product and their interrelations are of particular importance. Advancements in the cost-effect for the management of health care institutions depend on their managerial needs. Current trends in this regard primarily depend on treating all cost reference

  2. Optimization of radiological surveillance of occupationally-exposed workers in the Republic of Cuba

    International Nuclear Information System (INIS)

    This works analyzes the results of the dosimetric control to occupationally-exposed workers. during the 1987-1990 period. It states a criterium for knowing when it will be necessary to give or not an individual dosimeter to occupationally-exposed workers. It also proposes to take the dosimeter away to a number of workers as a result of such criterium

  3. Monitoring of occupationally exposed workers in a PET-centre

    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.

  4. 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)

  5. 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

    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

  8. 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

    A group of 50 workers exposed to coal tar pitch volatiles (CTPV) in an aluminum reduction plant and a group of 50 non-exposed workers were selected to evaluate the genotoxic effects of CTPV exposure. A battery of tests was performed on 3 different body fluids; urine, blood and semen. Urine samples were evaluated for mutagenic constituents using the Ames/Salmonella assay. Cultured lymphocytes from blood samples were used to perform cytogenetic analysis. Semen samples were used to measure sperm count, percent abnormal sperm morphology and frequency of sperm carrying double fluorescent bodies (2-F). 14 of 28 (50%) exposed workers and 7 of 36 (19.4%) non-exposed workers had mutagenic urine. This difference was significant (p less than 0.01). Among the non-smokers a significantly higher percentage of workers who were exposed had positive urine (36%) compared to the non-exposed workers (5%) (p less than 0.05). Among the exposed group, more mechanics had mutagenic urine than did other types of workers. Overall chromosome aberration rates were similar in both exposed and non-exposed workers. Among exposed workers a significant inverse correlation (p less than 0.05) between age and chromatid aberration rate was observed. Results of semen analysis failed to detect differences between exposed and non-exposed workers. Results of these tests lend support to a battery approach to genetic monitoring and suggest a link between exposure to CTPV and genotoxic effects. Detection of exposure to mutagens at an early time offers an opportunity for disease prevention by the reduction of exposure.

  10. 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

    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.

    Management and facilitation of care transitions from hospital to alternative settings requires skill and attention to avoid adverse events. Several interprofessional organizations and nurse leaders have called for the expansion and redesign of undergraduate nursing curricula to include care transitions. Yet there is little evidence describing how undergraduate baccalaureate nursing students are educated on this critical topic or how successful they are in improving student knowledge about care transitions. To address this gap, an in-classroom and clinical experience was implemented to prepare students to manage and facilitate care transitions from the hospital to alternative settings-including the home. Perceptions of undergraduate nursing students and home healthcare nurse preceptors were assessed via an electronic survey that was emailed to participants. Forty-eight responses to the survey were received. Students agreed this experience contributed to their understanding of caring for adults and older adults who are experiencing a care transition and they had a good understanding of care transitions to apply to their future nursing courses. Home healthcare nurse preceptors agreed they were able to demonstrate transitional care and that students were engaged. Future work should include expanding transitional care immersion to other care settings as well as the inclusion of additional healthcare disciplines in care transition education.

    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.

    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.

    A multidimensional selection battery was designed to predict a variety of criteria important in the selection of child care workers. The battery assesses constructs related to honesty, violence, substance abuse, emotional stability and safety. A series of studies were used to test the validity of the selection battery. Scores on the test battery were compared with those from three alternative selection procedures to define the measured constructs. Three additional studies show the relation of scores on the selection battery and the behavior of child care workers. The test battery was correlated with the job performance of child care workers and identified adults convicted for sexual offenses against minors. PMID:2263707

    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.

    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

  7. 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.

    The authors measured postshift urinary mutagenicity on a population of railroad workers with a range of diesel exhaust exposures. Postshift urinary mutagenicity was determined by a sensitive microsuspension procedure using Salmonella strain TA 98 {plus minus} S9. Number of cigarettes smoked on the study day and urinary cotinine were highly correlated with postshift urinary mutagenicity. Diesel exhaust exposure was measured over the work shift by constant-flow personal sampling pumps. The relative ranking of jobs by this adjusted respirable particle concentration (ARP) was correlated with relative contact the job groups have with operating diesel locomotives. After adjustment for cigarette smoking in multiple regressions, there was no independent association of diesel exhaust exposure, as estimated by ARP, with postshift urinary mutagenicity among smokers or nonsmokers. An important finding is the detection of baseline mutagenicity in most of the nonsmoking workers. Despite the use of individual measurements of diesel exhaust exposure, the absence of a significant association in this study may be due to the low levels of diesel exposure, the lack of a specific marker for diesel exhaust exposure, and/or urinary mutagenicity levels from diesel exposure below the limit of sensitivity for the mutagenicity assay.

    Full Text Available The present study investigates the functional integrity of liver among workers exposed to nickel during nickel-plating process. The functional integrity of liver was assessed in 69 workers who are exposed to nickel during nickel plating and considered as nickel-exposed workers; and 50 administrative workers residing in same city, but away from the place of work of study group, were considered as control group. The level of urine nickel was measured by using a flameless atomic absorption spectrophotometer. Using kits supplied by Bayer Diagnostics, we determined serum markers of liver function tests. Results: The levels of urine nickel were significantly increased in high-and moderate-exposure groups as compared to control group. The levels of serum transaminases -viz, alanine transaminase and aspartate transaminase-were significantly increased in nickel-exposed workers, who had high urine nickel levels as compared to control group. The level of serum albumin was negatively correlated with urine nickel levels. The levels of serum transaminases and serum g- glutamyl- transpeptidase were positively and significantly correlated with urine nickel levels. Conclusion: Results indicate that workers who had high urine nickel levels had a consistent effect on hepatic inflammatory function.

    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.

    1. Native Americans in the southwestern United States are considered a "vulnerable population." Native Americans have economic difficulties, poor health, and little access to health care. The Navajo nation is the largest Native American reservation in the United States. 2. Occupational health nurses who provide culturally competent care increase the likelihood for Navajo workers to obtain optimal benefits from workplace health services. 3. The nurse uses cultural assessment skills and critical thinking abilities to maximize therapeutic interactions and minimize barriers in communications with workers of other cultural backgrounds. 4. The nurse who is knowledgeable about the Navajo way can help achieve a balance between the traditional ways and Western ways of addressing serious health care issues facing the Navajo worker. This knowledge and cultural awareness also increases the effectiveness of health promotion and health education programs offered to workers, their families, and their communities. PMID:11760275

  2. 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.

    Inorganic arsenic (i-As) is a known human carcinogen; however, humans continue to be exposed to i-As in drinking water and in certain occupational settings. In this study, we used the Comet assay to evaluate DNA damage in the somatic cells of workers from three Polish copper smelters who were occupationally exposed to i-As. Blood samples were collected from 72 male workers and 83 unexposed male controls and used for the detection of DNA damage, oxidative DNA damage, and DNA damage after a 3-hr incubation in culture. Urine samples were collected to assess the level of exposure. The mean concentration of arsenic metabolites in urine [the sum of arsenite (AsIII), arsenate (AsV), monomethylarsenate (MMA) and dimethylarsenate (DMA)] and the concentrations of DMA (the main metabolite in urine) were higher in workers than in controls, but the differences were not statistically significant. By contrast, the level of DNA damage, expressed as the median tail moment, was significantly higher in the leukocytes of workers than in the controls. Comet assays conducted with formamidopyrimidine glycosylase (FPG) digestion to detect oxidative DNA damage indicated that oxidative lesions were present in leukocytes from both the exposed and control groups, but the levels of damage were significantly higher among the workers. Incubation of the cells in culture resulted in a significant reduction in the levels of DNA damage, especially among leukocytes from the workers, suggesting that the DNA damage was subject to repair. Our findings indicate that copper smelter workers have increased levels of DNA damage in somatic cells, suggesting a potential health risk for the workers. Although i-As was present in air samples from the smelters and in urine samples from workers, no clear association could be made between i-As exposure and the DNA damage. PMID:15880732

    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.

  10. Occupationally acquired HIV: the vulnerability of health care workers under workers' compensation laws.

    Science.gov (United States)

    Tereskerz, P M; Jagger, J

    1997-09-01

    Approximately 800,000 needlesticks and other sharp injuries from contaminated medical devices occur in health care settings each year, of which an estimated 16,000 are contaminated by human immunodeficiency virus (HIV). Health care workers who are occupationally infected by HIV are at risk of being left without workers' compensation coverage. In some states, the definition of an occupational disease is so restrictive that infected health care workers are unlikely to qualify for benefits. For those who are able to meet the definition, compensation is often inadequate. Recourse is also limited by statutory provisions that preclude health care workers from bringing civil suits against their employers. We recommend the amendment of legislation to provide more equitable remedies, including: (1) broadening the definition of occupational disease; (2) eliminating provisions that require a claimant to prove that (a) a specific occupational incident resulted in infection and (b) HIV is not an ordinary disease of life; (3) expanding the time for filing a claim; (4) assuring that lifetime benefits will be provided to the disabled health care worker; and (5) assuring that claims will remain confidential.

    2007-01-01

    The aim of this study was to investigate the actual situation of low back pain (LBP) prevention in care workers with questionnaires, and this data were used to clarify and decrease LBP factors. Subjects were 52 care workers (30.7 ± 10.0 years old) in a nursing home who filled out two kinds of questionnaires about LBP, one about the prevalence of LBP (QN1) and the other about LBP control measures (QN2). They had either license of certified care worker, 1st or 2nd class care worker. The data were collected for the purpose of finding differences in age and career (QN1) and differences in LBP control measures (QN2) between subjects with and without LBP. The average career of the subjects was 19.1 ± 12.5 months, and the prevalence of LBP among them was 46.2% (24 care workers), of which 66.7% began having LBP after starting work as care workers. Moreover, 75.0% of these subjects began having LBP within a year after starting work. Further, of the 24 care workers with LBP, 66.7% reported constantly experiencing LBP. The major risk factors given for LBP in care work were transfer, the replacement of diapers, and movement in a half-sitting posture. Compared with LBP subjects, rates of taking preventative steps in the non-LBP group were low. More than 80% of the subjects with LBP engaged in prevention methods such as using body mechanics, learning the proper way to perform care activities, using LBP support belts, and increasing their skills and knowledge with regard to their job responsibilities. Most subjects began to engage in such prevention methods after the onset of LBP. The results of this investigation indicated that most subjects did not engage in measures to counter their LBP until after it had already started, and that they selected prevention methods which were easy to perform and effective. It is important for care workers to learn the best ways to inhibit pain and prevent the occurrence, or recurrence, of LBP. It is necessary for physical therapists to grasp

    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.

    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.

  18. 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

  1. 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 textile printing industry in South India employs a great number of workers that may possibly be exposed to toxic compounds. In the present study, subjects from textile printing units were investigated for the presence of genetic damage in their peripheral blood lymphocytes using micronucleus assay. Proliferation was also investigated using a nuclear division index. It was found that the micronucleus frequency was considerably greater in exposed subjects than in non exposed control subjects, but division was not increased in a statistically significant way. For the time being, this investigation should be considered as a preliminary study in which the influence of potential confounders could be adequately assessed. However, our results are non-ambiguous, indicating a potential health risk in these workers.

    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.

    1998-07-01

    In order to know the changes of genetic toxicological effects on workers occupationally exposed to polycyclic aromatic hydrocarbons (PAHs), sister chromatic exchange(SCE) was detected by the methods of peripheral lymphocyte culture in 23 workers exposed to coal tar pitch (CTP) and in 19 workers exposed to coke oven volatiles (COV) and 12 normal controls. The results suggested that the SCE in occupational workers was significantly higher than that in controls (11.31 vs 6.37, P 0.05). It is indicated that CTP and COV caused strong genetic toxicity and injury to chromosome.

    Health care workers, children with spina bifida and rubber industry workers show higher prevalence of latex sensitization compared to the general population, and they are considered at-risk groups. Our aim was to establish the prevalence of latex allergy among health care workers at the Clínica Universitaria of Navarra and to analyze potential risk factors, including personal and family history of atopy, sex, as well as factors leading to enhanced exposure to latex, such as being a nurse, belonging to surgical departments, having undergone previous surgery and the number of gloves employed per week. Health care workers (n = 1,150) (doctors, nurses, assistant nurses, laboratory technicians and practicing medical and nursing students) were evaluated using a questionnaire and skin prick test (SPT). Serum specific IgE was determined by CAP-FEIA (Pharmacia, Sweden) in those with positive SPT. The participation index was 26.17%: 301 volunteers answered the questionnaire and underwent SPT. Fifteen subjects presented positive SPT to latex. It was found that 5% of the health care workers from the Clínica Universitaria were sensitized to latex allergens. Thirteen were females and two males. Mean age was 38.4 (+/- 7.09) years. Nine were nurses, three assistant nurses, one nursing student and two medical doctors. Eight belonged to medical, five to surgical and two to laboratory departments. There were no significant differences among the subjects in the prevalence of latex sensitization. Fourteen reported symptoms related to latex, mostly pruritus, dryness and/or redness of the hands (n = 12) and rhinitis (n = 6). Only one subject reported no symptoms when using latex products. Eight were atopic; personal history of atopy was the only significant (odds ratio = 5.10, p < 0.01) risk factor for latex sensitization. It was concluded that atopic health care workers show a more increased risk of latex sensitization than those who are nonatopic. PMID:10664929

  7. 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

    This paper reports the findings of a scoping study designed to describe the evidence base with regard to support workers in social care in the United Kingdom and to identify gaps in knowledge. Multiple bibliographic databases were searched for studies published since 2003. The results revealed that the support worker role, though not well-defined, could be characterised as one aimed at fostering independence among service users, undertaking tasks across social and health-care, and not being trained in, or a member of, a specific profession. The studies identified were predominantly small-scale qualitative projects which considered issues such as role clarity, training and pay, worker satisfaction, service user views and the amount of time support workers are able to spend with service users compared to other staff. The review concluded that the research base lacks longitudinal studies, there is definitional confusion and imprecision, and there is limited evidence about employment terms and conditions for support workers or about their accountability and performance. The desirability and value of training and how it is resourced need further analysis. It is concluded that moves to self-directed support or personalisation and the increased reliance on and use of support workers, in the form of personal assistants, call for closer scrutiny of the role.

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

    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.

    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 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

  17. Parallel assessment of male reproductive function in workers and wild rats exposed to pesticides in banana plantations in Guadeloupe

    2008-07-01

    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.

    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±42.32nmol/min/ml in controls) and phenylacetate (112.74±17.37 vs. 134.28±25.49μmol/min/ml in controls) was significantly lower in workers than in control subjects (p0.05). 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<0.001). For PON1(55)LM (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 variation in enzyme activities and DNA damage due to polymorphisms in PON1

    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...

  1. 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

    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.

  3. Thalamic GABA predicts fine motor performance in manganese-exposed smelter workers.

    Directory of Open Access Journals (Sweden)

    Zaiyang Long

    Full Text Available Overexposure to manganese (Mn may lead to parkinsonian symptoms including motor deficits. The main inhibitory neurotransmitter gamma-aminobutyric acid (GABA is known to play a pivotal role in the regulation and performance of movement. Therefore this study was aimed at testing the hypothesis that an alteration of GABA following Mn exposure may be associated with fine motor performance in occupationally exposed workers and may underlie the mechanism of Mn-induced motor deficits. A cohort of nine Mn-exposed male smelter workers from an Mn-iron alloy factory and 23 gender- and age-matched controls were recruited and underwent neurological exams, magnetic resonance spectroscopy (MRS measurements, and Purdue pegboard motor testing. Short-echo-time MRS was used to measure N-Acetyl-aspartate (NAA and myo-inositol (mI. GABA was detected with a MEGA-PRESS J-editing MRS sequence. The mean thalamic GABA level was significantly increased in smelter workers compared to controls (p = 0.009. Multiple linear regression analysis reveals (1 a significant association between the increase in GABA level and the duration of exposure (R(2 = 0.660, p = 0.039, and (2 significant inverse associations between GABA levels and all Purdue pegboard test scores (for summation of all scores R(2 = 0.902, p = 0.001 in the smelter workers. In addition, levels of mI were reduced significantly in the thalamus and PCC of smelter workers compared to controls (p = 0.030 and p = 0.009, respectively. In conclusion, our results show clear associations between thalamic GABA levels and fine motor performance. Thus in Mn-exposed subjects, increased thalamic GABA levels may serve as a biomarker for subtle deficits in motor control and may become valuable for early diagnosis of Mn poisoning.

  4. 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

    1989-01-01

    This paper presents the results of examinations of 522 workers exposed to various industrial dusts and 361 workers exposed to different concentrations of carcinogenic asbestos dust. The examinations showed a significantly higher incidence of total processes in the upper respiratory tract which manifested as chronic subatrophic nasopharingitis and hyperplastic laryngitis. Also, they demonstrated a significantly higher incidence of local processes that manifested as hyperplasia of the laryngeal mucosa and contact fibromas. These laryngeal lesions can be viewed as etiologically associated with the effect of industrial dusts having traumatic (abrasive and glass dust) and carcinogenic (asbestos) properties. Patients with the above laryngeal pathologies should be removed from the dust environment and sent to physical examinations with emphasis on occupational diseases.

    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

  7. Chest HRCT signs predict deaths in long-term follow-up among asbestos exposed workers

    International Nuclear Information System (INIS)

    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

    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.

    Workers in the coke oven industry are potentially exposed to low concentrations of benzene. There is a need to establish a well validated biological monitoring procedure for low level benzene exposure. The use of breath and blood benzene and urinary phenol has been explored in conjunction with personal monitoring data. At exposures of about 1 ppm benzene, urinary phenol is of no value as an indicator of uptake/exposure. Benzene in blood was measured by head space gas chromatography but the co...

    Incidence of cancer and mortality were studied among 674 men exposed to mercury vapour for more than one year at two chloralkali plants. Mercury excretion in urine had been monitored among the workers at the two plants since 1948 and 1949. An individual cumulative urinary mercury dose was calculated, based on about 20,000 urinary mercury measurements. The incidence of cancer and the mortality were followed up from 1953 to 1989 and 1953 to 1988 respectively. The general Norwegian male populati...

  15. 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.

  17. 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.

    Wollastonite metasilicate fibers are rather similar in form, length, and diameter, but mineralogically different, to amphibole asbestos fibers. We have studied immunologic findings from 46 men exposed to wollastonite at a limestone quarry for at least 10 years. These workers showed a higher prevalence of positive serum rheumatoid factors than blood donors did. This finding resembles the one detected among asbestos workers. The group of wollastonite workers with radiological signs of pulmonary fibrosis had activities of serum angiotensin-converting enzyme that were similar to those of wollastonite workers without fibrosis. A mortality study of 238 quarry workers with 5,769 person-years was, as expected, nonpositive. It was interesting that one woman with 20 years of exposure to wollastonite and with no other known exposure to fibers revealed a malignant retroperitoneal mesenchymal tumor 30 years after the initial exposure. This kind of very rare tumor is difficult to distinguish from mesothelioma. However, this is only one case, and it is impossible to draw any definite conclusions.

    Epidemiological studies have shown that mortality from malignant mesothelioma (MM) and lung cancer have increased with increasing cumulative exposure to asbestos. To investigate whether tumour-related biomarkers can contribute towards the evaluation of the carcinogenic risk in populations exposed to asbestos, the DNA adduct 8-hydroxy-2'-deoxyguanosine (80HdG), interleukine-6 (IL-6), platelet-derived growth factor (PDGF-BB), hepatocyte growth factor (HGF), basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGFbeta) and soluble mesothelin-related peptides (SMRPs) were analysed in a cohort of workers differently exposed to asbestos fibres at the workplace. To document biomarker levels in an unexposed population, 54 age-matched subjects were enrolled. A total of 119 subjects with a history of occupational exposure to asbestos underwent clinical examination and were interviewed by trained personnel, responding to a detailed questionnaire related to duration of asbestos exposure, smoking, and occupational task. According to the occupational tasks, asbestos-exposed subjects were analysed for their asbestos cumulative dose and the association with the biomarkers was evaluated. Among the occupational groups, maintenance workers, pipe fitters and electricians were exposed to a higher cumulative dose of asbestos fibres. Exposure to asbestos significantly increased the steady-state content of 80HdG in DNA. Elevated levels of 80HdG and IL-6 best reflected a high level of SMRPs, which is related to cell transformation. Subjects heavily exposed to asbestos [> 60(ff/cm3) x years] showed also a higher level of angiogenic factors. A combination of angiogenic biomarkers with a specific mesothelioma-biomarker such as SMRPs could be used for close surveillance of workers with a history of asbestos exposure. PMID:18638565

    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.

  1. 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

    To study the effects of serum p21 levels on the health of coal tar pitch(CTP) and coke oven volatiles (COV) workers recognized as the high risk population of pulmonary carcinoma, serum p21 levels among 24 cases of CTP workers, 25 cases of COV workers and 12 cases of normal control were detected with the method of Western Blotting. The results showed that the mean serum p21 level in exposed group was significantly higher than that in the normal control (366.8 vs 1270.7, P < 0.001). In the COV workers, serum p21 level in coke furnace workers was remarkably higher than that in the workers with other types of work. There were no differences for p21 among workers with different work years and between workers with or without smoking history. It indicates that CTP and COV can cause the p21 protein level increase in the occupational population.

    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.

    A total of 524 industrial workers were studied. They consisted of 442 noise exposed and 82 non-noise exposed workers. The purpose was to compare the prevalence of sensori-neural hearing loss among the noise exposed and the non-noise exposed workers, to study their knowledge on the hazard of noise to hearing and the workers' attitude towards the hearing protection devices. The prevalence of sensori-neural hearing loss was significantly higher among the noise exposed workers, i.e., 83% versus 31.7% (p workers, only 5.1% were wearing them regularly. The possibility of developing hearing loss due to exposure to excessive noise was only known by 35.5% of the noise exposed workers. This awareness was found to have a positive correlation with the workers' compliance to the hearing protection devices. Our findings highlight the need for workers to be educated on the hazards of excessive noise exposure to hearing.

    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.

    A descriptive and cross sectional study was conducted to determine whether hepatic function changes in workers occupationally exposed to a mixture of organic solvents, were due to the exposure or confusing factors. A non random sample of 77 workers, operators and supervisors of the Olefin Plant I and II of a petrochemical industry in Maracaibo, Venezuela, was used. Their mean age was 29 +/- 7 years, and had at least one year of exposure to the solvents. This sample was compared with a group of employees of the administrative offices or control panel workers, with a mean age of 36 +/- 8 year and with similar anthropometric characteristics. Workers with a known history of liver disease, blood transfusions and diabetes mellitus were excluded of the study. In addition to a complete occupational disease medical history and a physical examination, serum samples were obtained to determine the activity of the aspartato aminotransferase (AST), alanin aminotransferase (ALT), gamma glutamiltransferase (GGT), alkaline phosphatase (AF), the concentration of the total bile acids (BAS), the surface antigen of hepatitis B(HbsAg) and the hepatitis A virus antibodies: AntiHAV-IgG and the AntiHAV-IgM. An urine sample was taken and analyzed by standard methodology to determine urinary phenols. The air concentrations of benzene, ethylbenzene, toluene and xylene were analyzed by gas chromathography. The serum activities of the liver enzymes, the concentration of bile acids and urinary phenols were not influenced by the exposure to the solvents. The increase of the activity of GGT was associated with obesity and alcohol consumption. The antibodies of the surface antigen of hepatitis A-IgM were normal in both groups and the antibodies for the antigen of hepatitis A-IgG presented a prevalence of 6% in the exposed group and 9% in the non exposed not being associated with liver abnormalities. The individual air concentrations of the solvents were below the environmentally permissible

    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

    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

    In current practice the assessment of fitness for work in health care workers exposed to biomechanical risk factors is often based on conventional approaches rather than on evidence-based guidelines. However, an accurate evaluation of worker's psychophysical resources compared to job demand and potential occupational risk factors is essential in order to properly assess fitness for work. The latest published guidelines on the management of patients suffering from back pain reported that the evidence-based approach can minimize the period of inactivity by encouraging return to work (and to other non-dangerous physical activities) in a relatively short period of time. As for carpal tunnel syndrome, there is no scientific evidence supporting a restriction of physical activities requiring forceful movements of the hand/wrist. PMID:22838297

    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.

    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

  20. 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.

    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

    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.

    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

  5. 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)

    In order to assess the possible human carcinogenicity of formaldehyde we conducted a retrospective cohort mortality study of workers exposed for at least three months to formaldehyde in three garment facilities which produced permanent press garments. A total of 11,030 workers contributing 188,025 person-years were included in the study. Vital status was successfully ascertained through 1982 for over 96% of the cohort. The average (TWA) formaldehyde exposure at the three plants monitored in 1981 and 1984 by NIOSH was 0.15 ppm but past exposures may have been substantially higher. In general, mortality from nonmalignant causes was less than expected. A statistically significant excess in mortality from cancers of the buccal cavity (SMR = 343) and connective tissue (SMR = 364) was observed. Statistically nonsignificant excesses in mortality were observed for cancers of the trachea, bronchus and lung (SMR = 114), pharynx (SMR = 112), bladder (SMR = 145), leukemia and aleukemia (SMR = 113), and other lymphopoietic neoplasms (SMR = 170). Mortality from cancers of the trachea, bronchus and lung was inversely related to duration of exposure and latency. In contrast, mortality from cancers of the buccal cavity, leukemias, and other lymphopoietic neoplasms increased with duration of formaldehyde exposure and/or latency. These neoplasms also were found to be highest among workers first exposed during a time period of high potential formaldehyde exposures in this industry (1955-1962). However, it should be recognized that these findings are based on relatively small numbers and that confounding by other factors may still exist. The results from this investigation, although far from conclusive, do provide evidence of a possible relationship between formaldehyde exposure and the development of upper respiratory cancers (buccal), leukemias, and other lymphopoietic neoplasms in humans.

    Full Text Available Introduction: The respiratory tract is one of the main points of entry of foreign substances into the body. Because of its location, the respiratory tract is heavily exposed to harmful agents, such as gases, vapors, or aerosols. Aim: Our objective was to evaluate the symptoms of occupational rhinitis in workers exposed to cotton dust. Method: The prospective study population consisted of workers from the "Nova Esperança" Cooperative of Nova Odessa (Sao Paulo, who were studied between September and December 2008. Data were collected through an individually and privately answered questionnaire designed by the author considering the clinical criteria for rhinitis. Results: Using the questionnaire, we evaluated a total of 124 workers. Among these patients, 63.7% complained of nasal obstruction, 57.2% of nasal itching, 46.7% of rhinorrhea, and 66.1% of sneezing. Of the patients considered to have very serious symptoms, 9% had nasal obstruction; 9%, itching; 4%, rhinorrhea; and 6.4%, sneezing. Discussion: Aerosol agents in the environment can clearly aggravate and even initiate rhinitis. From the standpoint of pathogenesis, the mechanisms of classical allergic airway inflammation involving mast cells, IgE, histamine, eosinophils, and lymphocytes may be responsible for the development of rhinitis after exposure to high molecular weight allergens such as proteins derived from animals and plants. This study showed a strong relationship between the occupational exposures associated with work in the cotton textile industry and the symptoms of rhinitis. Conclusion: Analysis of the data clearly showed the occurrence of rhinitis symptoms in these patients, demonstrating that the prevention and treatment of this condition in the workplace is extremely important.

    Cholangiocarcinoma is a relatively rare cancer, but its incidence is increasing worldwide. Although several risk factors have been suggested, the etiology and pathogenesis of the majority of cholangiocarcinomas remain unclear. Recently, a high incidence of early-onset cholangiocarcinoma was reported among the workers of a printing company in Osaka, Japan. These workers underwent high exposure to organic solvents, mainly haloalkanes such as 1,2-dichloropropane (1,2-DCP) and/or dichloromethane. We performed whole-exome analysis on four cases of cholangiocarcinoma among the printing workers. An average of 44.8 somatic mutations was detected per Mb in the genome of the printing workers’ cholangiocarcinoma tissues, approximately 30-fold higher than that found in control common cholangiocarcinoma tissues. Furthermore, C:G-to-T:A transitions with substantial strand bias as well as unique trinucleotide mutational changes of GpCpY to GpTpY and NpCpY to NpTpY or NpApY were predominant in all of the printing workers’ cholangiocarcinoma genomes. These results were consistent with the epidemiological observation that they had been exposed to high concentrations of chemical compounds. Whole-genome analysis of Salmonella typhimurium strain TA100 exposed to 1,2-DCP revealed a partial recapitulation of the mutational signature in the printing workers’ cholangiocarcinoma. Although our results provide mutational signatures unique to occupational cholangiocarcinoma, the underlying mechanisms of the disease should be further investigated by using appropriate model systems and by comparison with genomic data from other cancers.

    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. Our data indicates that sugar cane burning, that generates polycyclic aromatic hydrocarbons, represents a genotoxic risk for workers in this important sugar cane producing area in Mexico.

    We conducted hospital-based contact investigations of 55 serial sputum smear-positive tuberculosis (TB) patients and 771 health care workers (HCWs) from 2006-2013. HCWs who made contact with TB patients in the absence of appropriate airborne precautions were evaluated using interferon gamma release assays to identify TB infection. Twenty-nine HCWs (3.8%) were newly diagnosed with TB infection. The 10 TB patients responsible for transmission had a duration of contact of >7 days by multivariate analysis. PMID:26777287

    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.

    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.

    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.

    Full Text Available BACKGROUND: In October 2007, a cluster of patients experiencing a novel polyradiculoneuropathy was identified at a pork abattoir (Plant A. Patients worked in the primary carcass processing area (warm room; the majority processed severed heads (head-table. An investigation was initiated to determine risk factors for illness. METHODS AND RESULTS: Symptoms of the reported patients were unlike previously described occupational associated illnesses. A case-control study was conducted at Plant A. A case was defined as evidence of symptoms of peripheral neuropathy and compatible electrodiagnostic testing in a pork abattoir worker. Two control groups were used - randomly selected non-ill warm-room workers (n = 49, and all non-ill head-table workers (n = 56. Consenting cases and controls were interviewed and blood and throat swabs were collected. The 26 largest U.S. pork abattoirs were surveyed to identify additional cases. Fifteen cases were identified at Plant A; illness onsets occurred during May 2004-November 2007. Median age was 32 years (range, 21-55 years. Cases were more likely than warm-room controls to have ever worked at the head-table (adjusted odds ratio [AOR], 6.6; 95% confidence interval [CI], 1.6-26.7, removed brains or removed muscle from the backs of heads (AOR, 10.3; 95% CI, 1.5-68.5, and worked within 0-10 feet of the brain removal operation (AOR, 9.9; 95% CI, 1.2-80.0. Associations remained when comparing head-table cases and head-table controls. Workers removed brains by using compressed air that liquefied brain and generated aerosolized droplets, exposing themselves and nearby workers. Eight additional cases were identified in the only two other abattoirs using this technique. The three abattoirs that used this technique have stopped brain removal, and no new cases have been reported after 24 months of follow up. Cases compared to controls had higher median interferon-gamma (IFNgamma levels (21.7 pg/ml; vs 14.8 pg/ml, P<0

    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.

    Shorter telomere length (TL) in peripheral blood lymphocytes (PBLs) is predictive of lung cancer risk. Polycyclic aromatic hydrocarbons (PAHs) are established lung carcinogens that cause chromosome instability. Whether PAH exposure and its molecular effects are linked with shorter TL has never been evaluated. In the present study, we investigated the effect of chronic exposure to PAHs on TL measured in PBLs of Polish male non-current smoking cokeoven workers and matched controls. PAH exposure and molecular effects were characterized using measures of internal dose (urinary 1-pyrenol), effective dose [anti-benzo[a]pyrene diolepoxide (anti-BPDE)-DNA adduct], genetic instability (micronuclei, MN) and DNA methylation [p53 promoter and Alu and long interspersed nuclear element-1 (LINE-1) repetitive elements, as surrogate measures of global methylation] in PBLs. TL was measured by real-time polymerase chain reaction. Cokeoven workers were heavily exposed to PAHs (79% exceeded the urinary 1-pyrenol biological exposure index) and exhibited lower TL (P = 0.038) than controls, as well as higher levels of genetic and chromosomal alterations [i.e. anti-BPDE-DNA adduct and MN (P < 0.0001)] and epigenetic changes [i.e. p53 gene-specific promoter and global methylation (P worker (P = 0.039) and in all subjects with higher levels of anti-BPDE-DNA adduct (P = 0.042), p53 hypomethylation (P = 0.005) and MN (P = 0.009). In multivariate analysis, years of work in cokery (P = 0.008) and p53 hypomethylation (P = 0.001) were the principal determinants of shorter TL. Our results indicate that shorter TL is associated with chronic PAH exposure. The interrelations with other genetic and epigenetic mechanisms in our data suggest that shorter TL could be a central event in PAH carcinogenesis.

  20. 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.

  1. 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.

    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

    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 Latex allergy has become an occupational hazard among healthcare workers. Atopy, intensity and duration of exposure have been recognized as predisposing factors for latex sensitization. Frequency of sensitization varies among countries. So we decided to investigate the prevalence of latex sensitization and potential risk factors among healthcare workers in a general hospital. In a cross sectional study by distributing a questionnaire among 876 employees of a general hospital, we investigated the prevalence of latex allergy and the potential risk factors for latex sensitization. We collected information about occupational history, including specific tasks performed, time of first exposure to latex, number of pairs of gloves used, and duration of weekly exposure. We also investigated the interval between first exposure and onset of symptoms. We asked about pre-existing rhinoconjuctivitis, asthma, atopic and contact dermatitis, hay fever, autoimmune diseases, and food allergies. This survey documented a high prevalence of adverse reaction to all latex containing materials (52.5%. 37.7% of responder had adverse reaction to latex gloves. The highest prevalence of adverse reaction to all latex containing materials was found in the surgical operating room, followed by emergency unit and internal medicine wards. According to this study, frequency of adverse reaction to latex was high among health care workers. This may be due to relatively low response rate, low quality of latex products in Iran, and the method of measurement. Whenever, the need for implementing prevention program, using latex-free methods and training of employees to reduce adverse reaction to latex is apparent.

    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.

    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. .

    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.

    1983-01-01

    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).

  13. 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.

    Urine samples taken after work and after a free weekend from 50 workers employed in various activities in a chemical plant manufacturing explosives were analysed. On the basis of hygienic surveys, the subjects were divided into three categories of exposure to trinitrotoluene (TNT). The urine analyses consisted of gas chromatographic identification of TNT and its two metabolites, 4-ADNT and 2-ADNT, and a determination of the mutagenic activity. Two frame shift detector strains of Salmonella typhimurium were used, TA 98 and TA 98 NR, the latter being deficient in endogenous nitroreductase activity. On the basis of previous results on TNT mutagenicity, no exogeneous metabolic system was used to test the urine concentrates. Both tester strains showed that the mean urinary mutagenic activity was higher in the after work samples than in post weekend samples from the same subjects, showing that bacterial nitroreductase activity was not significantly responsible for the mutagenicity, although the response was higher with strain TA 98 than with TA 98 NR. The interindividual variation in urine mutagenicity was high, however, and the difference between the two sampling times was statistically significant (p less than 0.05) only for the high exposed group (workers in trotyl foundry and sieve house). Correlation between urinary mutagenicity and concentration of TNT in urine was poor; correlation was significant only with the urinary concentration of 4-ADNT. The correlation between urinary TNT and both metabolites was good (p less than 0.001). These results suggest that analysis of 4-ADNT in urine would be a sufficient biological measure for controlling exposure to TNT.

Radionuclides associated to a pharmaceutical compound used at this Department are {sup 131}I, {sup 18}F, {sup 68}Ga, {sup 99m}Tc, {sup 111}In and {sup 11}C 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 {sup R}eglamento General de Seguridad Radiologica{sup ,} Mexico (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.

    This study was conducted to assess the occupational exposure and its health impact on the chromium alloyworkers. Environmental and biological monitoring, noise and audiometry measurements were done to evaluate theexposure levels in the factory. A total of 112 non-smoking workers were monitored from July 2001 to August 2002.The results showed that most of the chromium and lead exposures in the factory were below the ACGIH-TWA of 50μg/m3 for chromium( Ⅵ ) and OSHA-PEL of 50 μg/m3 for lead. The highest chromium(7.25 ± 0. 16 μg/m3 ) and lead(14.50 ± 0.29 μg/m3) concentrations were measured in the vibro room. The results indicated that elevatedconcentrations of chromium and lead were found in both blood and urine samples especially in those areas whichwere characterized by poor ventilation. The metal contents in blood and urine samples were significantly correlatedwith airborne metal concentrations in the factory. The result demonstrated that blood and urinary levels amongworkers were associated with increasing age and duration of exposure.The background noise level of the factory ranged from 67.6 to 89.2 dBA and was frequently higher than thethreshold limit value for noise(90 dBA). According to the audiometric test, the exposed workers showed signs ofnoise-induced hearing loss. Noise at work continued to be an important factor to hearing loss among exposedworkers. In our statistical analysis, a significant hearing loss was established on age effect and year of exposureamong the workforce.

    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

    Full Text Available The present study targeted health care workers (HCWs in Governmental Hospitals and Primary Health Care Centers in Abha City, southwestern Saudi Arabia. An anonymous self-report questionnaire was used to assess tobacco use and the reasons for smoking. The present study included 736 HCWs. The overall prevalence of tobacco use amounted to 26.3% (14.8% current and 11.5% former users. In a binary logistic regression analysis, males were found significantly more prone to smoke compared to females (aOR = 3.081, 95% CI: 2.004–4.739. Similarly, parental history of tobacco use was found to be a significant risk factor (aOR = 1.540, 95% CI: 1.040–2.278. Among current users, 89.9% were interested in quitting and 66.1% tried before to quit. The prevalence of smoking among HCWs in the present study, besides being a public health problem, represents a potential barrier in involving this group as a first line for tobacco control. There is a need for a national intervention programme in the country in a tailored manner for HCWs to control tobacco use parallel to the running national program for public. These interventions should begin early in basic medical education and to be applied continually during one’s medical career.

    At the suggestion of a social worker who witnessed abusive post-abortion care at a public hospital in Rosario, Argentina, two human rights NGOs collaborated to investigate women's experiences seeking treatment for abortion complications at area public hospitals. During the year-long enquiry, more than 300 women took part. Role play was successfully used to surmount women's initial reluctance to reveal pervasive discriminatory and humiliating mistreatment. Thirty-one women later gave personal testimonies about their experiences, which were contained in the report of the research and later dramatised in a public meeting and video. The report, Con Todo al Aire (With Everything Exposed), was disseminated widely, including to the media, and a formal complaint was made to the local Ombudsman, who called for high-level action to resolve the problems. Initial denial by some health professionals that there was a serious problem was replaced by critical self-assessment within the provincial government, hospitals and medical and nursing schools, who made commitments to reform hospital practices and the medical school curriculum. Women participants also gained an understanding of their right to appropriate and humane health care. The findings from Rosario are not isolated. They are now being shored with activists and researchers in other provinces of Argentina and other countries. PMID:15938156

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).

    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.

    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.

    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.

    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

    Full Text Available Background: The Polish occupational health system (OHS, existing over the past 17 years, has recently been contested as never before. Critical voices pertain to both legislative and executive aspects of the system, in which key roles are played by employers and occupational medicine service. There are some reasons for making a hypothesis that relevant norms are not always respected by the main actors. Material and methods: The data on the observance of norms by entities responsible for providing workers with prophylactic health care were analyzed. They were obtained from the existing external resources and materials collected during the implementation of tasks assigned by the Ministry of Health. Results: Legal norms, which constitute OHS in Poland are generally neither respected by the employers, nor by the representatives of occupational medicine service. Nearly half (45–47% of employers infringe provisions relating to medical examinations of workers. Such a degree of non-observance of respective laws would have not been the case if it was not for the attitudes and “silent approval” of many (but not all occupational physicians. Laws defining the responsibilities of occupational medicine service units on one hand, and of employers on the other, are for many reasons infringed by both groups. Conclusions: The data analyses indicate that the Polish OHS is, to a large extent, not acceptable and should be replaced with another one founded on other assumptions and responsive to contemporary occupational health challenges. New provisions should be formulated on the basis of merit and guided by socially accepted norms. Med Pr 2015;66(6:815–825

    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.

  10. 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

    Despite the fact that working with asbestos and placing it on the market have been banned in Germany since 1993 according to the Ordinance on Hazardous Substances, asbestos-related diseases of the lungs and pleura are still the leading cause of death in occupational diseases. The maximum industrial usage of asbestos was reached in former West Germany in the late 1970s and in former East Germany the late 1980s. Occupational diseases, mainly mesotheliomas and lung cancer emerging now are thus caused by asbestos exposure which occurred 30-40 years earlier. It is known that the combination of smoking and asbestos exposure results in a superadditive increase in the risk to develop lung cancer. No suitable screening methods for early detection of malignant mesothelioma are currently available and the therapeutic options are still very limited; however, the national lung screening trial (NLST) has shown for the first time that by employing low-dose computed tomography (LDCT) in heavy smokers, lung cancer mortality can be significantly reduced. According to current knowledge the resulting survival benefits far outweigh the potential risks involved in the diagnostic work-up of suspicious lesions. These results in association with the recommendations of international medical societies and organizations were pivotal as the German statutory accident insurance (DGUV) decided to provide LDCT as a special occupational medical examination for workers previously exposed to asbestos and with a particularly high risk for developing lung cancer.

    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.

  14. 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)

  16. 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.

    The Nováky Power Station (NPS) has been using since 1953 as fuel coal with a high content of As and with a low content of other metals. This involves a constant risk for the workers as well as pollution of the surroundings. The authors described 16 cases of chronic As intoxication in NPS workers after 22.3 +/- 8.4 years of exposure (especially stokers, maintenance workers, boiler cleaners). Among clinical symptoms prevailed sensory and motor polyneuropathy (13 cases), pseudoneurasthenic syndrome (10 cases), toxic encephalopathy (6 cases) and nasal septum perforation (2 cases). After 1989 the intoxications with As did not occur any more due to technical measures and health protection of the workers. The authors present a review of actual results of clinical, haematological and biochemical investigations and tests for metals (AAS methods) in biological materials of workers at risk in NPS (n = 70), exposed on average for 11.9 +/- 0.5 years, of average age 35.91 +/- 1.7 years (mean +/- SE) and compared the results to a matched control group of blood donors not exposed to metals (n = 29). In NPS workers significantly lower Hb values, higher serum creatinine, higher serum beta 2-microglobulin, higher As content in hair as well as higher serum Mn and Pb concentrations compared with the C-group were found. The exposed group had significantly lower serum Se concentrations (0.64 +/- 0.025 mumol/l (mean +/- SE) compared to Se levels of persons from an adjacent district. The authors stress the necessity of individual evaluation of the metal concentrations in relation to clinical findings. With prolonged exposure the situation can become more urgent not only because of chronic poisoning but also because of the cancerogenic effects of these elements on the human organism. PMID:9524739

    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.

    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.

    Full Text Available Welding is a process in which two or more metals are attached by the use of heat and, in some cases, pressure. Direct exposure and inhalation of welding fumes causes acute and chronic side effects in humans. Kidney damage is one of these important side effects. β2 microglobulin is an 11.8 kilodalton protein and levels increase in the case of some inflammatory and viral diseases, or kidney malfunction and autoimmune diseases. In this study measurements of β2 microglobulin were used as a criterion for assessing effects on the kidneys of workers exposed to welding fumes. The study population were electric arc welders in an industrial plant in Tehran, Iran. For control we selected workers who did not have any exposure to welding fumes. Both groups were selected on the basis of a questionnaire and the consideration of criteria for inclusion and exclusion. In the end 50 cases and 50 controls were chosen. A urine sample was collected from all participants and urinary pH was set to between 6-8 using NaOH (1M. Sample transportation to the laboratory complied with the related standards. The samples were assessed using the ORG 5BM kit. For quantitative assessment of β2 microglobulin we used the Enzyme-linked Immunosorbent Assay (ELISA method. The ages of the welders ranged from 21 to 48 years (mean=30.5±5.9 yrs and of controls from 23 to 56 years (mean=31.8±5.9 yrs. Mean employment duration was 7.86±5.01years (range 2 to 27 years for welders. Mean β2 microglobulin level was 0.10±0.096 μg/ml in welders and 0.11±0.06 in controls. This difference was not statistically significant (P=0.381. In conclusion we don't find that exposure to electric arc welding fumes cause a significant change in urinary β2 microglobulin compared to the control group.

    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 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.

    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

    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.

    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

  7. 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.

    The detrimental effect of nuclear accidents due to localized or whole body radiation exposure results in severe cellular damage. The current study was carried out to evaluate radiation-mediated variability in blood components of metal scrap workers exposed accidently to cobalt-60 source. Blood samples collected initially from five hospitalized patients, coded P1-P5, were processed for total leukocyte counts (TLC), platelet (PLT) counts, haemoglobin, estimation of DNA double strand breaks by measuring phosphorylated form of H2AX (γ-H2AX) and chromosomal aberrations (dicentrics). Blood cells count (TLC), in all the patients except P2, was found decreased. Dicentrics increased in all the five patients. γ-H2AX was found significantly elevated in patients P2 and P4. After 3 days, 21 subjects working in close vicinity of accident site were evaluated for the above-mentioned markers to confirm their possibility of radiation exposure; however, all the parameters in these subjects were found within normal limits. Blood from patients P1-P5 was collected again after 11 days. Studies revealed exorbitant increase in γ-H2AX in lymphocytes and monocytes of patients P1, P4 and P5. TLC and PLT count in these patients had fallen further. Dicentrics declined with time in all the five patients. Based on the studied blood biomarkers, we conclude that the five subjects showed signs of radiation exposure. Measurement on radiation dose could not be performed in the current study; however, the generated data particularly on dicentrics provide ample evidence of radiation exposure.

    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

  12. 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.

    Full Text Available Abstract Occupational exposures play a role in the onset of several chronic airway diseases. We investigated, in a cross-sectional study, lung function parameters and bronchial hyper-responsiveness to histamine in workers exposed to different airborne compounds. The study group totalled 546 male subjects of whom 114 were exposed to welding fumes, 106 to solvents, 107 to mineral dust, 97 to organic dust and 123 without known exposure to airway irritants. A questionnaire was administered and spirometry and bronchial responsiveness to histamine were assessed by one observer, in the morning before work to prevent effects of acute exposure. The mean (SD age of the participants was 39.3 (7.8 years, with a mean duration of employment of 13.8 (6.6 years. Both before and after adjustment for smoking status, forced expiratory volume in 1 second (FEV1, expressed as % predicted was lower in welders -4.0% (95% confidence interval [CI], -6.3 to -1.8; p = 0.01 and workers exposed to solvents -5.6% (CI: -7.9 to -3.3; p = 0.0009 than in control subjects. Furthermore, solvent workers had an odds ratio of 3.43 (95% CI: 1.09–11.6; p = 0.037 for bronchial hyperresponsiveness compared with the reference group. The higher prevalence of bronchial hyperresponsiveness in solvent workers adds to the growing body of evidence of adverse respiratory effects of occupational solvent exposure. These results point to the necessity of preventive measures in solvent workers to avoid these adverse respiratory effects.

  14. 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.

    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.

    Because of their involvement in the transport, handling, preparation, administration, or disposal of hazardous medications, health care workers across multiple settings are at risk for adverse health consequences from exposure to these drugs. This review presents evidence-based strategies to mitigate the harmful exposures. These include engineering controls, full use of personal protective equipment, medical and environmental monitoring, hazard identification, and the need for a comprehensive hazardous drug control program that includes education and training for health care workers.

    Full Text Available Background/Aim. Industrial noise is produced in workshops due to factory machinery and tools used in technological processes. It has detrimental effect to primarily the organ of the sense of hearing, thus damaging hearing in oversensitive subjects. The aim of the study was to perform a detailed analysis of audiometric and, especially, impedancemetric parameters in workers exposed to the effects of industrial noise of various duration, as well as to determine similarities and differences in workers with differences in sensitivity to damaging effects of noise. Methods. The study included a homogenous group of 173 industrial workers involved in the same department of a huge workshop named 'Kovačica' exposed to noise level above a threshold intensity, and divided into three groups: the group I of 116 workers (232 ears exposed to noise for 8 h in the workshop 'Kovačica', the group II of 41 workers (82 ears exposed to noise only half of the working time, and the group III of 16 workers (32 ears exposed to the same conditions and having the normal hearing sense. The group III served as a control group. Prior to the study any workers went through a thorough anamnesis and complete ORL examination, and then they were submitted to audiometric testing. The study included only the workers with no hearing damage due to diseases, injuries nor other detrimental factors in order to be sure that the hearing findings had been caused by industrial noise. Results. The results obtained by audiometric testing showed that 90.75% of the workers had hearing damage of various degrees, while 9.25 % of the workers had regular hearing although had been exposed to the same conditions. More severe hearing damage was revealed in the workers of the group I. Tympanometricly, in most ears of the group I workers (65.52% a compliance value was found to be more than 0.9 cm3, while in the majority of those of the group II (59.75% a compliance value was in the range from 0.5 to 0

    The aim of this article was to describe and analyze the work of community health workers (CHW). The main objective of study was to analyze the development process of primary health care practices related to drug consumption. The study is based on the Marxist theoretical orientation and the action research methodology, which resulted in the performance of 15 emancipatory workshops. The category work process spawned the content analysis. It exposed the social abandonment of the environment in which the CHWs work is performed. The latter had an essential impact on the identification of the causes of drug-related problems. These findings made it possible to criticize the reiterative, stressful actions that are being undertaken there. Such an act resulted in raising of the awareness and creating the means for political action. The CHWs motivated themselves to recognize the object of the work process in primary health care, which they found to be the disease or addiction in the case of drug users. They have criticized this categorization as well as discussed the social division of work and the work itself whilst recognizing themselves as mere instruments in the work process. The latter has inspired the CHW to become subjects, or co-producers of transformations of social needs.

    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

    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, p<0.01). The average notification rate of TB among health care workers over the last 5 years was two times higher than in the general population (280.4/100,000 compared to 153.9/100,000). Regression results showed that ethnicity, designation, family contact and TB related knowledge 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

    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.

    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

  13. 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.

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.

  16. 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

    Benzene exposure has been causally linked with acute myeloid leukemia (AML), but inconsistently associated with other hematopoietic, lymphoproliferative and related disorders (HLD) or solid tumors in humans. Many neoplasms have been described in experimental animals exposed to benzene. We used Poisson regression to estimate adjusted relative risks (RR) and the likelihood ratio statistic to derive confidence intervals for cause-specific mortality and HLD incidence in 73,789 benzene-exposed compared with 34,504 unexposed workers in a retrospective cohort study in 12 cities in China. Follow-up and outcome assessment was based on factory, medical and other records. Benzene-exposed workers experienced increased risks for all-cause mortality (RR = 1.1, 95% CI = 1.1, 1.2) due to excesses of all neoplasms (RR = 1.3, 95% CI = 1.2, 1.4), respiratory diseases (RR = 1.7, 95% CI = 1.2, 2.3) and diseases of blood forming organs (RR = ∞, 95% CI = 3.4, ∞). Lung cancer mortality was significantly elevated (RR = 1.5, 95% CI = 1.2, 1.9) with similar RRs for males and females, based on three-fold more cases than in our previous follow-up. Significantly elevated incidence of all myeloid disorders reflected excesses of myelodysplastic syndrome/acute myeloid leukemia (RR = 2.7, 95% CI = 1.2, 6.6) and chronic myeloid leukemia (RR = 2.5, 95% CI = 0.8, 11), and increases of all lymphoid disorders included excesses of non-Hodgkin lymphoma (RR = 3.9, 95%CI = 1.5, 13) and all lymphoid leukemia (RR = 5.4, 95%CI = 1.0, 99). The 28-year follow-up of Chinese benzene-exposed workers demonstrated increased risks of a broad range of myeloid and lymphoid neoplasms, lung cancer, and respiratory diseases and suggested possible associations with other malignant and non-malignant disorders.

    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.

  20. 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.)

    Dental erosion, and specifically its symptoms, has long been studied in Japan as an occupational dental disease. However, in recent years, few studies have investigated the development of this disease or labor hygiene management aimed at its prevention. As a result, interest in dental erosion is comparatively low, even among dental professionals. Our investigation at a lead storage battery factory in 1991 found that the work environmental sulfuric acid density was above the tolerable range (1.0mg/m(3)) and that longterm workers had dental erosion. Therefore, workers handling sulfuric acid were given an oral examination and rates of dental erosion by tooth type, rates of erosion by number of working years and rates of erosion by sulfuric acid density in the work environment investigated. Where dental erosion was diagnosed, degree of erosion was identified according to a diagnostic criterion. No development of dental erosion was detected in the maxillary teeth, and erosion was concentrated in the anterior mandibular teeth. Its prevalence was as high as 20%. Rates of dental erosion rose precipitously after 10 working years. The percentages of workers with dental erosion were 42.9% for 10-14 years, 57.1% for 15-19 years and 66.7% for over 20 years with 22.5% for total number of workers. The percentages of workers with dental erosion rose in proportion to work environmental sulfuric acid density: 17.9% at 0.5-1.0, 25.0% at 1.0-4.0 and 50.0% at 4.0-8.0mg/m(3). This suggests that it is necessary to evaluate not only years of exposure to sulfuric acid but also sulfuric acid density in the air in factory 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.

  7. Carcinogenesis and Inflammatory Effects of Plutonium-Nitrate Retention in an Exposed Nuclear Worker and Beagle Dogs

    International Nuclear Information System (INIS)

    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.

    Research has shown that workers employed in footwear manufacture are at increased risk of some cancers, the strongest evidence being for nasal cancer and leukemia. Footwear-workers are routinely exposed to complex mixtures of solvents in degreasers, cleaners, primers, and adhesives used in the production process as toluene, n-hexane, acetone, and possibly dust particles, additives in shoe materials and degradation products of materials. The recognition of the potential health-hazards of solvent-based adhesives (SBAs) has lead to the development of adhesives with no organic solvents, the water-based adhesives (WBA). We investigated footwear-workers (all males) exposed to SBA (n=29) (for 3.98+/-4.13 years), and WBA (n=16), which had spent the six months previous to the study employed in an experimental section which used only water-based adhesives, although they had previously worked in sections which used solvent-based adhesives (for 5.80+/-4.03 years); 25 healthy subjects were used as controls. The Comet assay and the micronucleus test were used as endpoints, while the traditional parameters for assessing exposure to toluene in organic mixtures by measuring the concentration of urinary hippuric acid were also assessed. Our results showed a significantly lower mean concentration of hippuric acid in the control group than found in the SBA (Pdamage index for the SBA (Pcomparison to the WBA group and control (Pwater-based adhesives are clearly a better option for safeguarding the health of footwear-workers, even with possibility of isocyanate presence, while the positive results observed in SBA group might be explained by chloroprene presence in the adhesive.

    Diesel engine exhaust (DEE) was found to induce lipid peroxidation (LPO) in animal exposure studies. LPO is a class of oxidative stress and can be reflected by detecting the levels of its production, such as malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE), and etheno-DNA adducts including 1,N(6)-etheno-2'-deoxyadenosine (ɛdA) and 3,N(4)-etheno-2'-deoxycytidine (ɛdC). However, the impact of DEE exposure on LPO has not been explored in humans. In this study, we evaluated urinary MDA, 4-HNE, ɛdA, and ɛdC levels as biomarkers of LPO among 108 workers with exclusive exposure to DEE and 109 non-DEE-exposed workers. Results showed that increased levels of urinary MDA and ɛdA were observed in subjects occupationally exposed to DEE before and after age, body mass index (BMI), smoking status, and alcohol use were adjusted (all p < 0.001). There was a statistically significant relationship between the internal exposure dose (urinary ΣOH-PAHs) and MDA, 4-HNE, and ɛdA (all p < 0.001). Furthermore, significant increased relations between urinary etheno-DNA adduct and MDA, 4-HNE were observed (all p < 0.05). The findings of this study suggested that the level of LPO products (MDA and ɛdA) was increased in DEE-exposed workers, and urinary MDA and ɛdA might be feasible biomarkers for DEE exposure. LPO induced DNA damage might be involved and further motivated the genomic instability could be one of the pathogeneses of cancer induced by DEE-exposure. However, additional investigations should be performed to understand these observations. PMID:27087348

    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.

    2007-09-29

    Only few usable studies into the effect of influenza vaccination of health-care workers on sick leave and influenza among their patients are available in the literature. However, together these studies provide consistent evidence that this vaccination is effective and cost effective, reducing the death rate from all causes of residents of nursing homes for the elderly by 27-44%. Therefore, measures to raise the vaccination rate among health-care workers, which is at present under 25%, are highly recommended. However, more studies in this field are needed.

    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.

    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.

    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

  2. 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

    2015-03-01

    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

    We report 2 cases of hepatotoxicity in cleanroom workers due to high retained chloroform air concentrations. The women, aged 34 and 41 years, who had been working in a medical endoscopic device manufacturer as cleanroom workers for approximately 40-45 days suffered severe liver damage. Two measured time-weighted averages of the chloroform concentration in the air in the cleanroom were 82.74 and 64.24 ppm, which are more than 6 times the legal occupational exposure limit in Korea. Only 7% of the cleanroom air was newly introduced from outside. The clinical courses of these cases and workplace inspection, led us to conclude that both cases of hepatotoxicity were caused by chloroform exposure.

    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.

    The study aimed to monitor heavy metal (chromium, Cr; cadmium, Cd; nickel, Ni; copper, Cu; lead, Pb; iron, Fe; manganese, Mn; and zinc, Zn) footprints in biological matrices (urine, whole blood, saliva, and hair), as well as in indoor industrial dust samples, and their toxic effects on oxidative stress and health risks in exposed workers. Overall, blood, urine, and saliva samples exhibited significantly higher concentrations of toxic metals in exposed workers (Cr; blood 16.30 μg/L, urine 58.15 μg/L, saliva 5.28 μg/L) than the control samples (Cr; blood 5.48 μg/L, urine 4.47 μg/L, saliva 2.46 μg/L). Indoor industrial dust samples also reported to have elevated heavy metal concentrations, as an example, Cr quantified with concentration of 299 mg/kg of dust, i.e., more than twice the level of Cr in household dust (136 mg/kg). Superoxide dismutase (SOD) level presented significant positive correlation (p ≤ 0.01) with Cr, Zn, and Cd (Cr > Zn > Cd) which is an indication of heavy metal's associated raised oxidative stress in exposed workers. Elevated average daily intake (ADI) of heavy metals resulted in cumulative hazard quotient (HQ) range of 2.97-18.88 in workers of different surgical units; this is an alarming situation of health risk implications. Principal component analysis-multiple linear regression (PCA-MLR)-based pie charts represent that polishing and cutting sections exhibited highest metal inputs to the biological and environmental matrices than other sources. Heavy metal concentrations in biological matrices and dust samples showed a significant positive correlation between Cr in dust, urine, and saliva samples. Current study will help to generate comprehensive base line data of heavy metal status in biomatrices and dust from scientifically ignored industrial sector. Our findings can play vital role for health departments and industrial environmental management system (EMS) authorities in policy making and implementation.

    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)

    Full Text Available ObjectivesFew epidemiological studies have studied the effect of 2,3,7,8-tetrachlorodibenzo-p dioxin (TCDD on blood cytokine levels. In this study we investigated changes in plasma levels of a large panel of cytokines, chemokines and growth factors among workers from a Dutch historical cohort occupationally exposed to chlorophenoxy herbicides and contaminants including TCDD.MethodsEighty-five workers who had been exposed to either high (n=47 or low (n=38 TCDD levels more than 30 years before serum collection were included in the current investigation. Plasma level of 16 cytokines, 10 chemokines and 6 growth factors were measured. Current plasma levels of TCDD (TCDDCurrent were determined by high resolution gas chromatography/isotope dilution high resolution mass spectrometry. TCDD blood levels at the time of last exposure (TCDDmax were estimated using a one-compartment first order kinetic model. ResultsBlood levels of most analytes had a negative association with current and estimated past maximum TCDD levels. These decreases reached formal statistical significance for fractalkine, transforming growth factor alpha (TGF-α and fibroblast growth factor 2 (FGF2 with increasing TCDD levels.ConclusionsOur study showed a general reduction in most analyte levels with the strongest effects for fractalkine, FGF2 and TGF-α. These findings suggest that TCDD exposure could suppress the immune system and that chemokine and growth factor-dependent cellular pathway changes by TCDD may play role in TCDD toxicity and associated health effects.

  13. 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.

    Full Text Available We discuss the changing epidemiological situation of pertussis observed in recent years, with a focus on the shift of cases from young children to older age groups, teenagers and adults. Whooping cough may affect healthcare workers who belong to a high-risk group and cause hospital infections. We present a case report of pertussis in a nurse and the recommended prophylactic measures in healthcare workers. The current definition and diagnosis of pertussis is also discussed. The clinical course of pertussis can be significantly alleviated and highly non-specific, with no typical coughing and vomiting in people vaccinated against whooping cough a few years earlier. Pertussis should be considered in the differential diagnosis of cough lasting more than fourteen days. Improvement of the epidemiological situation requires, besides immunization of infants, regular and universal booster immunization for adolescents and adults. Vaccinations for health care workers of neonatal and pediatric wards are recommended in the National Program of Immunization for 2013. It seems that booster vaccination of health care workers with a triple vaccine against diphtheria, tetanus and acellular pertussis (dTpa of the reduced quantity of antigens, particularly of health workers caring for infants, children and the elderly, may be the most effective way to reduce the risk of pertussis transmission in the health care environment.

    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.

    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.

    Full Text Available Benzene is a ubiquitous environmental pollutant and an important industrial chemical present in both gasoline and motor vehicle emissions. Occupational human exposure to benzene occurs in the petrochemical and petroleum refining industries as well as in gas-station workers, where it can lead to benzene poisoning (BP, but the mechanisms of BP are not completely understood. In Brazil, a significant number of gas-station service workers are employed. The aim of the present study was to evaluate alterations related to BP and metabolic polymorphisms in gas-station service workers exposed to benzene in the city of Rio de Janeiro, Brazil. Occupational exposure was based on clinical findings related to BP, and metabolic polymorphisms in 114 Brazilian gas-station attendants. These workers were divided into No Clinical Findings (NCF and Clinical Findings (CF groups. Neutrophil and Mean Corpuscular Volume (MCV showed a significant difference between the two study groups, and neutrophil has the greatest impact on the alterations suggestive of BP. The clinical findings revealed higher frequencies of symptoms in the CF group, although not all members presented statistical significance. The frequencies of alleles related to risk were higher in the CF group for GSTM1, GSTT1, CYP2E1 7632T > A, but lower for NQO1 and CYP2E1 1053C > T genotypes. Moreover, an association was found between GSTM1 null and alterations related to BP, but we did not observe any effects of other polymorphisms. Variations in benzene metabolizing genes may modify benzene toxicity and should be taken into consideration during risk assessment evaluations.

    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.

    The objective of this study was to determine whether daytime occupational exposure to extremely low frequency magnetic fields (MFs) suppresses nocturnal melatonin production. Sixty female volunteers were recruited. Thirty-nine worked in a garment factory, and 21 office workers served as a reference group. Exposure assessment was based on the type of sewing machine used and MF measurements around each type of machine. Eye-level MF flux density was used to classify the operators to higher (> 1 microT) and lower (0.3-1 microT) exposure categories. A third group of factory workers had diverse MF exposures from other sources. The reference group had average exposure of about 0.15 microT. Urine samples were collected on Friday and Monday for three consecutive weeks. Melatonin production was assessed as urinary 6-hydroxymelatonin sulfate (6-OHMS) excretion. The ratio of Friday morning/Monday morning 6-OHMS was used to test the hypothesis that melatonin production is suppressed after 4 days of occupational MF exposure with significant recovery during the weekend. Possible chronic suppression of melatonin production was evaluated by studying exposure-related differences in the Friday values by multivariate regression analysis. The Monday/Friday ratios were close to 1.0, suggesting that there is no increase in melatonin production over the weekend. The average 6-OHMS excretion on Friday was lower among the factory workers than in the reference group, but no monotonous dose-response was observed. Multivariate regression analysis identified MF exposure, smoking, and age as significant explanatory variables associated with decreased 6-OHMS excretion.

    In order to evaluate the human carcinogenicity of formaldehyde, the authors conducted a proportionate mortality study of garment workers engaged in the production of shirts from formaldehyde-treated cloth. This study included three plants, and was based upon 256 deaths identified from a death-benefit insurance fund. No deaths due to nasal cancer were observed, and the mortality from respiratory cancer (11 cases, PMR = 95) was slightly less than expected. Statistically significant (p less than . 05) elevations in proportionate mortality were observed for malignant neoplasms of the ''buccal cavity'' (three cases, PMR = 750), for ''biliary passages and liver'' (four cases, PMR = 313) and for ''other lymphatic and hematopoietic sites'' (four cases, PMR = 400). A proportionate cancer mortality (PCMR) analysis also was conducted, and cancer of the ''buccal cavity'' (three cases, PCMR = 682), and other ''lymphatic and hematopoietic sites'' (four cases, PCMR = 342) were still significantly elevated. The observed excesses in cancer mortality were primarily experienced by white females, who made up the major portion of the workforce, and workers with more than 10 years of latency and duration of exposure, a criterion for inclusion for most workers in the study group. The neoplasms observed were not equally distributed among the three facilities included in the study. Because of the small number of deaths involved and the lack of consistency with other studies, the authors believe that these findings should be viewed cautiously, pending the outcome of more definitive studies.

    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

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

    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

    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

    The purpose of this article is to examine youth care workers' perceptions of the specific and unique sexual health needs of youth at risk for foster care. Semistructured interviews were conducted with youth care workers (N = 10) at a shelter for youth in or at risk for foster care. Youth care workers perceive that youth have unique experiences and needs related to sexual health programming and pregnancy prevention. Reflecting a great deal of family dysfunction, 3 themes emerged that revealed perceived benefits of teen pregnancy: youths' effort to prove themselves as adults, opportunity to secure their relationship with a partner, and desire to create an emotional connection with a baby. Lack of knowledge and accumulation of risk factors were viewed as most problematic. Current pregnancy prevention programs assume teen pregnancies are unwanted and emphasize the costs of sexual risk taking. Current findings suggest that sexual health programming for youth in or at risk for foster care should account for 3 perceived benefits of teen pregnancy. New opportunities for improving the reach and effectiveness of intervention for youth in or at risk for foster care are discussed.

    2013-01-01

    Subjective well-being (SWB), usually called 'happiness', is influenced directly by psychological factors. Personality and resilience (capacity of recover from adversity) are included among these factors. Empirical evidence has demonstrated that resilience is an essential and inherent characteristic for the nursery staff. This study has aimed to analyze personality factors (including resilience) related with SWB (satisfaction with life, positive and negative affect) in a nursery staff sample (n=59) of intensive care and cardiological units, and a non-health care workers sample (n=50) mainly made up of government employees and teachers. Multiple regression analyses showed that SWB was associated with more resilience and less neuroticism in the nursery staff. Extraversion and conscientiousness (positively related), and neuroticism (negatively related) were the significant predictors of SWB in the non-health care workers group. Finally, mediational analyses revealed that resilience measured the relationships between extraversion (total mediation) and neuroticism (partial mediation) with SWB in the nursery staff group, but not in the group of non-health care workers. The results show the importance of resilience for nursery staff of intensive care units, since they are constantly exposed to human suffering and to a continually adverse occupational environment. Likewise, the discussion stresses that resilience is a means for nursing staff to cope with the occupational stress and that resilient nurses are a crucial element in our health care system.

    Trichloroethylene (TCE) has been associated with a variety of immunotoxic effects and may be associated with an increased risk of non-Hodgkin lymphoma (NHL). Altered serum immunoglobulin (Ig) levels have been reported in NHL patients and in animals exposed to TCE. Recently, we reported that occupational exposure to TCE is associated with immunosuppressive effects and immune dysfunction, including suppression of B-cell counts and activation, even at relatively low levels. We hypothesized that ...

    An extension of a male reproductive study conducted in a boric acid/borate production zone at Bandırma, Turkey, is presented. The relation between DNA-strand breaks (COMET assay, neutral and alkaline version) in sperm cells and previously described sperm quality parameters was investigated in boron-exposed males. A correlation between blood boron levels and mean DNA-strand breaks in sperm was weak, and DNA-strand breaks in sperm were statistically not different between control and exposed groups. Therefore, increasing boron exposures had no additional contribution in addition to already pre-existing DNA-strand breaks in the sperm cells. Weak but statistically significant correlations between DNA-strand breaks and motility/morphology parameters of sperm samples were observed in the neutral version of the COMET assay, while correlations between the same variables were statistically not significant in the alkaline version. A likely reason for these negative results, even in highly exposed humans, is that experimental exposures that had led to reproductive toxicity in animals were significantly higher than any boron exposures, which may be reached under realistic human conditions.

  11. 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)

    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.

    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

    Fitness for work (FFW) is the final task of both risk assessment and health surveillance, aimed at protecting workers' health and working capacity. There are numerous specific concerns regarding health care workers. In particular: i) the frequent difficulty in determining at pre-employment/pre-placement examinations the specific task that the individual worker will perform; ii) the prevalence of female workers and the contemporary presence of numerous occupational risk factors that are a potential cause of harmful effects on women's reproductive health; iii) the progressive aging of the staff especially nurses; iv) the risk to third parties, with particular reference to the issues of biological risk and substance abuse, also in relation to shift work, fatigue and occupational stress; v) the increasing number of immigrant workers among support staff In such cases the occupational physician, respecting both ethical principles and regulations and with an appropriate balance between scientific evidence and the precautionary principle, should express a FFW judgment that allows both the adaptation of work to the worker and vice versa, as recommended by the World Health Organization (WHO) and the International Commission on Occupational Health (ICOH). Proper FFW judgment also permits the expected benefits to be achieved, not only for the workers but also for employers, companies and society.

  15. 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)

    1991-12-01

    Medium-density fiber (MDF) board was recently introduced in the furniture industry. In this pilot study health complaints, physiology, and histology of the upper airways were evaluated for two groups of workers, one handling MDF board for at least one-third of their work week (MDF group) and another handling traditional fiber board. Civil servants served as a reference group. The frequency of health complaints concerning the airways was higher, the sense of smell was poorer, and the frequency of nasal obstruction measured with rhinomanometry was higher for the MDF group, while mucociliary activity was lower in the group handling traditional board. In both groups forced vital capacity was low when compared with expected values. Histological specimens from the middle turbinate of the nose showed, in a few cases, nasal epithelial dysplasia in the traditional board group, but histological changes in terms of scoring did not differ significantly between the groups.

    2007-04-01

    Skill mix and role redesign have changed the face of the primary care workforce in the UK in recent years. In areas with minority ethnic communities, support workers with language skills and cultural knowledge have been employed to provide health care. Although this role is relatively new to the UK, countries like Pakistan have a long history of employing community support workers. This study seeks to learn from Pakistan's experience and apply the learning to the UK context. The findings from this study suggest that the support worker role in Pakistan is highly effective when training and adequate supervision is given and when the support worker is entrusted with a considerable degree of freedom to act. It was also observed that the same role might be highly effective in one context, but less so in another, which indicates the importance of exploring a range of factors that may affect outcomes. The study provided an invaluable opportunity to gain a better understanding of the health care system in Pakistan. This may assist in the development of services in the UK to improve primary health care, particularly for those who experience barriers in accessing services. PMID:17455572

    Aasheim, Erlend T; Seymour, Martin; Balogun, Koye; Ngui, Siew-Lin; Williams, Chris J; Shankar, Ananda Giri

    2013-11-01

    Hepatitis A virus (HAV) is considered one of the most important vaccine-preventable diseases in travelers. HAV spreads from person to person via the fecal-oral route and gives rise to an estimated 1.4 million cases worldwide each year. In developing countries with poor sanitary conditions people tend to be infected during childhood and have few symptoms, whereas in developed countries with good sanitary conditions fewer people develop immunity during childhood. This leads to susceptible populations of adults, who are also more prone to severe complications. Here we describe two confirmed cases of hepatitis A associated with a nursing home. The index case was a care worker who had recently traveled to a high-endemicity country, and the second case was a resident at the nursing home where the index case worked. Both cases had an identical genotype IIIA strain, consistent with a transmission event. Current policy does not include a requirement for hepatitis A vaccine in care workers who travel to high endemicity countries despite the fact that infected care workers can potentially spread the disease to elderly patients and other groups at risk of severe complications from HAV infection. We suggest that employers should consider hepatitis A vaccine upon employment; particularly in care workers who plan to visit areas where HAV is known to be endemic.

    Full Text Available Background The risk of occupationally acquired tuberculosis (TB remains a concern, even now that the infection has been under control to a great extent. Objectives The aim of this study was to ascertain the prevalence of latent TB infection and pulmonary TB, and to assess the risk factors for TB, among health care workers in Hamadan. Patients and Methods Tuberculin skin test was performed on 245 health care workers, in two educational hospitals. The reaction was considered as "positive" if the induration diameter was ≥ 10 mm. Individuals with a positive test > than 15 mm were encouraged to seek further medical evaluation, including a chest-x-ray and a smear and sputum culture of the sputum for acid-fast bacilli, in those with radiographic changes indicating TB. Results Out of 245 health-care workers included in this study, 92 (38% had positive tuberculin test. There was a significant association between aging and tuberculin positivity. There was also a significant association between the length of employment and tuberculin positivity. Ward attendants had higher rates of positive test results, compared with other occupational groups. Conclusions It was concluded that latent TB infection is common among health-care workers in the studied region. Age, occupational group and employment length were found to be strongly associated with tuberculin positivity.

  17. 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

    2013-02-01

    Full Text Available Background: The frequency of respiratory symptoms in workers exposed to water aerosol was evaluated along with the preliminary assessment of microbiological contamination of air and water used in glass processing plants. Material and Methods: A questionnaire survey was conducted in 131 workers from 9 glass processing plants. Questions focused on working conditions, respiratory symptoms and smoking habits. A pilot study of air and water microbiological contamination in one glass processing plant was performed. Water samples were tested for Legionella in accordance with EN ISO 11731-2:2008 and for total colony count according to PN-EN ISO 6222:2004. Air samples were tested for total numbers of molds and mildews. Results: During the year preceding the survey acute respiratory symptoms occurred in 28.2% of participants, while chronic symptoms were reported by 29% of respondents. Increased risks of cough and acute symptoms suggestive of pneumonia were found among the respondents working at a distance up to 20 m from the source of water aerosol compared to other workers (OR = 2.7, with no difference in the frequency of other symptoms. A microbiological analysis of water samples from selected glass plant revealed the presence of L. pneumophila, exceeding 1000 cfu/100 ml. The number of bacteria and fungi detected in air samples (above 1000 cfu/m3 suggested that water aerosol at workplaces can be one of the sources of the air microbial contamination. Conclusions: The questionnaire survey revealed an increased risk of cough and acute symptoms suggestive of pneumonia in the group working at a shortest distance form the source of water aerosol.

    Full Text Available Problem statement: An in-house health promotion program aimed at promoting safety and health awareness when handling organic solvents at the workplace was carried out and its effectiveness was evaluated by comparing the Knowledge, Attitude and Practices (KAP scores at the pre and post-intervention phase. Approach: A total of 104 workers participated in the program and another 176 workers served as the comparative group. Questionnaire was distributed to respondents for the program evaluation on the KAP as well as to obtain their background information. The program consisted of small group lectures and discussions, a short video show, display of posters and distributions of pamphlets. Results: Pre-intervention data showed poor practice and knowledge scores on solvent hazards (Conclusion: There were improvements in the KAP scores of the intervention group at the post-intervention phase. However, the practice was not significantly correlated to the knowledge, instead, it was influenced by the employment years in the heavily solvent exposed sections in the Painting Department indicating that their job experience and peer group interactions contributed to their work culture and behavior.

    2005-01-01

    AIM: To analyze occupational health hazards exposure to doses lower than the Chinese occupational health standard in a selected VC polymerization plant in China,and also to elucidate the relationship between genetic polymorphisms and genetic susceptibility on liver lesions of workers exposed to vinyl chloride monomer (VCM).METHODS: In order to explore the mechanism of VCM-related health effects, we used a case-control design to investigate the association between the genetic polymorphisms of metabolic enzymes and liver lesions in workers occupationally exposed to VCM. Genotypes of CYP2E1, GSTT1, GSTM1, ALDH2 and ADH2 were identified using PCR and PCR-RFLP.RESULTS: Even when the concentration of VCM was lower than the current Chinese occupational health standard,neurasthenia, pharyngeal irritation, liver ultrasonography abnormalities and hemoglobin disorders were significantly higher in exposure subjects compared to non-exposure subjects, and the relative risks (RR and 95% CI) were 1.74 (1.06-2.85), 1.97 (1.56-2.48), 10.69 (4.38-26.12),and 2.07 (1.20-3.57). CYP2E1 c1c2/c2c2 genotype was significantly associated with liver damages (OR 3.29, 95% CI 1.51-7.20, P<0.01).CONCLUSION: The incidences of neurasthenia and liver ultrasonography abnormalities significantly increase when the cumulative exposure dose increases. The genotypes of metabolic enzymes (CYP2E1 c1c2/c2c2, null GSTT1 and ADH2 1-1) play important roles in VCM metabolism.Polymorphisms of CYP 2E1, GSTT1 and ADH2 may be a major reason of genetic susceptibility in VCM-induced hepatic damage.

    Previous studies have revealed that organophosphate pesticides (OPs) are primarily metabolized by xenobiotic metabolizing enzymes (XMEs). Very few studies have explored genetic polymorphisms of XMEs and their association with DNA damage in pesticides-exposed workers. Present study was designed to determine the influence of CYP2C9, GSTM1, GSTT1 and NAT2 genetic polymorphisms on DNA damage in workers occupationally exposed to OPs. We examined 268 subjects including 134 workers occupationally exposed to OPs and an equal number of normal healthy controls. The DNA damage was evaluated using alkaline comet assay and genotyping was done using individual polymerase chain reaction (PCR) or polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Acetylcholinesterase and paraoxonase activity were found to be significantly lowered in workers as compared to control subjects which were analyzed as biomarkers of toxicity due to OPs exposure (p<0.001). Workers showed significantly higher DNA tail moment (TM) compared to control subjects (14.32±2.17 vs. 6.24±1.37 tail % DNA, p<0.001). GSTM1 null genotype was found to influence DNA TM in workers (p<0.05). DNA TM was also found to be increased with concomitant presence of NAT2 slow acetylation and CYP2C9*3/*3 or GSTM1 null genotypes (p<0.05). DNA TM was found increased in NAT2 slow acetylators with mild and heavy smoking habits in control subjects and workers, respectively (p<0.05). The results of this study suggest that GSTM1 null genotypes, and an association of NAT2 slow acetylation genotypes with CYP2C9*3/*3 or GSTM1 null genotypes may modulate DNA damage in workers occupationally exposed to OPs.

  4. ROMANIAN SOCIAL CARE WORKERS' EXPOSURE TO WORKPLACE VIOLENCE

    Directory of Open Access Journals (Sweden)

    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.

    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

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.

    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

  10. 35. Detection of numerical chromosome aberrations in sperm of workers exposed to benzene series by two-color fluorescence in situ hybridization

    2001-01-01

    To study the frequency of numerical chromosome aberrations in sperm of workers exposed to benzene series, the aneuploidy frequencies of 9 and 18 chromosomes were detected in sperm of workers by two color fluorescence in situ hybridization with digoxingenin labeled 9 chromosome probe (D9zl) and biotin labeled 18 chromosome probe (D18zl). The timeweight average air concentration (TWA ) of benzene in the workplace was 86.49 mg/m3, it was two fold higher than the national maximum allowable concentration. The concentration of urinary trans,trans-muconic acid (ttMA) in exposed group was significantly higher than that of control group. The sperms counted in 14 exposed workers and 16 control workers were 136 401 and 156 955 respectively. The results showed that the disomy frequencies of sperm for chromosome 9, 18 in (0.168%±0.063% and 0.055%±0.031% respectively) and the frequency of diploidy sperm (0.073%±0.045%) were statistically increased over that of the control group(0.050%±0.030%; 0.033%±0.025% and 0.040%±0.036%, respectively). The nullisomic frequencies of 9,18 chromosome in the exposed group (0.206%±0.047%, 0.068%±0.044%) were statistically increased over that of the control group too (0.067%±0.037%, 0.048%±0.034%). The frequency of overall numerical chromosome aberrations in the exposed group was 0.570%±0.144%, when this value was compared with that of control (0.218%±0.071%), a statistically significance was presented. Our experiments showed that exposed to benzene at higher concentration may induce increase in aneuploidy frequency of sperm autosomal chromosome in exposed workers.

    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.

    Tuberculosis remains one of the communicable diseases that cause increased morbidity and mortality worldwide. With an incidence rate of 13,04 per 100,000 population, Spain ranks third among the most affected European countries. These data show a tendency to decrease meaning that it may go unnoticed with the potential to miss the appropriate preventive measures in a suspected case. In centers where patients are treated with tuberculosis, health care worker presents risk of transmission. This risk is higher in some areas or work units. The Occupational health physicians' services, which monitorize the health of health care workers, use different strategies in order to prevent and detect tuberculosis infection. The national guidelines include the tuberculin skin test as a screening test for tuberculosis infection with mention of new diagnostic tests based on the in vitro detection of gamma interferon (IGRA) for certain cases. The purpose of this guide is to establish common criteria for IGRA tests, as a supplementary aid to the tuberculin skin test in health care workers, from the evidence available today. Recommendations for its use have been adapted to the different situations faced by the professionals involved in monitoring the health of health workers.

    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

    Rubber allergy is an important occupational health problem for an increasing number of patients. It may produce a type I urticarial reaction, or more commonly, a type IV delayed eczematous dermatitis. The risk groups include health care workers, rubber industry workers, and children with spina bifida (meningomyelocele) and urogenital abnormalities. In this report, we describe a physician with a relevant history who was found to have type I hypersensitivity to rubber by prick test and use test. Our aim is to increase awareness among physicians, discuss diagnosis and management, and review the literature. PMID:9470325

    Full Text Available Abstract Background Health worker motivation can potentially affect the provision of health services. The HIV pandemic has placed additional strain on health service provision through the extra burden of increased testing and counselling, treating opportunistic infections and providing antiretroviral treatment. The aim of this paper is to explore the challenges generated by HIV care and treatment and their impact on health worker motivation in Mbeya Region, Tanzania. Methods Thirty in-depth interviews were conducted with health workers across the range of health care professions in health facilities in two high HIV-prevalence districts of Mbeya Region, Tanzania. A qualitative framework analysis was adopted for data analysis. Results The negative impact of HIV-related challenges on health worker motivation was confirmed by this study. Training seminars and workshops related to HIV contributed to the shortage of health workers in the facilities. Lower status workers were frequently excluded from training and were more severely affected by the consequent increase in workload as seminars were usually attended by higher status professionals who controlled access. Constant and consistent complaints by clients have undermined health workers' expectations of trust and recognition. Health workers were forced to take responsibility for dealing with problems arising from organisational inefficiencies within the health system. Conclusion HIV-related challenges undermine motivation among health workers in Mbeya, Tanzania with the burden falling most heavily on lower status workers. Strained relations between health workers and the community they serve, further undermine motivation of health workers.

    The United Automobile Workers International Union has established a system of epidemiologic triage to evaluate patterns of mortality among groups of union members. In response to worker concerns, the Union examined mortality at a metal stamping plant, using a method which linked pension records with the State of Michigan computerized death registry. The observed proportion of malignant neoplasms was nearly twice that expected (95% Confidence Limits 1.36, 2.62). Two- to five-fold excess proportional mortality from cancer of the digestive organs, lung cancer, and leukemia accounted for most of the overall excess. Strong associations were found between lung and digestive organ cancer and employment as maintenance welders or millwrights in the plant (odds ratios greater than 10). High levels of six polycyclic aromatic hydrocarbons with mutagenic and carcinogenic properties were found during hot coal tar application to wood block floors, work conducted by the high-risk groups. These levels were substantially reduced following the purchase of new tar pots. The example demonstrates that epidemiologic tools can play a valuable role in occupational health decision making, but care must be taken to avoid mechanical reliance on quantitative testing and to acknowledge the important role of social and political value judgments in the establishment of responsible public policy.

    Employees exposed to formaldehyde in the woodworking industry (N = 47) and nonexposed control subjects (N = 20) were examined in 1980 by spirometry and the nitrogen washout technique. A transient impairment of lung function was noted over a work shift. Five years later, 21 subjects were still experiencing exposure to formaldehyde. A transient decrease in lung function was again found over a work shift, as evidenced by a reduction in forced mid-expiratory flow (FEF25-75) of 0.15 l/s and an increase in closing volume (CV%) of 3.0% in nonsmokers. Significant decreases in forced expired volume in 1 s as a percent of forced vital capacity (FEV1.0/FVC) and FEF25-75 were also noted over the 5 y in nonsmokers (0.4% and 0.2 l.s/y, respectively, after correction for normal aging). After 4 wk of no exposure (holidays), FEF25-75 and forced expired vital capacity (FVC, FEV1.0) returned to normal in the smoking group. Lung function in smokers improved less during the holiday. A dose-response relationship was found between exposure to formaldehyde and decrease in lung function. Thus, industrial exposure to formaldehyde causes transient lung function impairment over a work shift, with a cumulative effect over the years. The impairment, however, can be reversed with 4 wk of no exposure.

  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 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.

    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

    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)

    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

    Preferred provider organizations (PPOs) provide healthcare services to an expanding proportion of the U.S. population. This paper presents a programmatic assessment of service quality in the workers' compensation environment using two different models: the PPO program model and the fee-for-service (FFS) payor model. The methodology used here will augment currently available research in workers' compensation, which has been lacking in measuring service quality determinants and assessing programmatic success/failure of managed care type programs. Results indicated that the SERVQUAL tool provided a reliable and valid clinical quality assessment tool that ascertained that PPO marketers should focus on promoting physician outreach (to show empathy) and accessibility (to show reliability) for injured workers.

    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.

    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

    To confirm the relationship between exposure to coal tar pitch volatiles and bladder cancer among primary aluminum production workers, we carried out a case-control study among blue-collar workers who had worked more than 1 year between 1950-1979 in a major plant using mostly the Soderberg process in the Province of Québec. Cases of bladder cancer (ICD code 188) diagnosed between 1970-1979 (n = 69) were mostly included in a previously reported study. To these were added cases diagnosed between 1980-1988 (n = 69). Each case was matched to three controls on date of birth, date of hiring, and length of service at the company. Smoking habits were assessed from the medical records at the company. Benzene-soluble matter (BSM) and benzo(a)pyrene (BaP) were used as indicators of environmental exposure to coal tar pitch volatiles in the workplace. The estimated risk for current smokers was 2.63 (95% C.I. 1.29-5.37). Estimates of risk by occupational exposure were adjusted for smoking. Men who had worked in the Soderberg potrooms were at higher risk of developing the disease, the risk increasing with the time spent in these departments. Similarly, a strong association between risk and cumulative exposure to BSM or to BaP was observed. The risks associated with cumulative exposure to BSM (mg/m3-years) and to BaP (microgram/m3-years) were described with mathematical models. Using a linear model (1 + bx) and lagging 10 years before the diagnosis, BaP cumulative exposure was a better indicator of risk than BSM cumulative exposure. The risk for each year of exposure to BaP at a concentration of 1 microgram/m3 increased by 1.7% (0.8%-3.2%). Using the same model for BSM, a worker exposed to the current threshold limit value of 0.2 mg/m3 for 40 years will sustain a risk of 2.22 (1.56-3.48). Comparison of risks according to different periods of diagnosis (1970-1979 vs. 1980-1988) did not reveal any significant temporal changes on risk estimates.

    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

    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

  18. Neopterin: A candidate biomarker for the early assessment of toxicity of aluminum among bauxite dust exposed mine workers

    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.

  19. 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)

    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.

    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 communicative behaviors. The findings suggest that a person-centered care-based psycho-educational 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.

    Integration of the vertical leprosy programme into the existing horizontal health programme poses various administrative and operational challenges to programmers. In order to understand the preparedness of the PHC workers for integration of leprosy into primary health care services, 71 PHC workers were interviewed using a structured interview schedule. The results showed that about 42% of the staff have heard of the concept of integration earlier and 90% of the PHC staff are willing to treat leprosy patients in the primary health care centre, but only 72% were in favour of integration. The reasons for favouring integration were (1) wider coverage with MDT, (2) frequent field visits by the worker, (3) better rapport with the community, (4) timely treatment and (5) cost-effectiveness. About 28% of the staff members did not favour integration for the reasons that the leprosy programme would suffer, targets cannot be met, supervision would be difficult, knowledge of the staff was inadequate and importance cannot be given to leprosy as family planning is always a priority in PHC centres. About 43% of the staff felt that the performance of the leprosy programme would be better after integration. With regard to workload, 60% of the sample felt that there would be increase in the workload in the field, record maintenance and supervision. The difficulties foreseen by the workers were grouped into 6 categories, viz., administrative, managerial, technical, personnel, social and miscellaneous. It is worth noting that 91% of the staff that included all categories said they were not afraid of leprosy, but needed training in leprosy work. About 50% of the staff expected increase in salaries and promotions if integration took place.

    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. Conclusions This study corroborates previous reports of frequent physical and verbal aggression towards care workers in the various areas of

    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

    New, comprehensive, approaches for chronic disease management are needed to ensure that patients, particularly those more likely to experience health disparities, have access to the clinical care, self-management resources, and support necessary for the prevention and control of diabetes. Community health workers (CHWs) have worked in community settings to reduce health care disparities and are currently being deployed in some clinical settings as a means of improving access to and quality of care. Guided by the chronic care model, Baylor Health Care System embedded CHWs within clinical teams in community clinics with the goal of reducing observed disparities in diabetes care and outcomes. This study examines findings from interviews with patients, CHWs, and primary care providers (PCPs) to understand how health care delivery systems can be redesigned to effectively incorporate CHWs and how embedding CHWs in primary care teams can produce informed, activated patients and prepared, proactive practice teams who can work together to achieve improved patient outcomes. Respondents indicated that the PCPs continued to provide clinical exams and manage patient care, but the roles of diabetes education, nutritional counseling, and patient activation were shifted to the CHWs. CHWs also provided patients with social support and connection to community resources. Integration of CHWs into clinical care teams improved patient knowledge and activation levels, the ability of PCPs to identify and proactively address specific patient needs, and patient outcomes.

    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.

    Any potential health effects of radiation emitted from radionuclides deposited in the bodies of workers exposed to radioactive materials can be directly investigated through epidemiological studies. However, estimates of radionuclide exposure and consequent tissue-specific doses, particularly for early workers for whom monitoring was relatively crude but exposures tended to be highest, can be uncertain, limiting the accuracy of risk estimates. We review the use of job-exposure matrices (JEMs) in peer-reviewed epidemiological and exposure assessment studies of nuclear industry workers exposed to radioactive materials as a method for addressing gaps in exposure data, and discuss methodology and comparability between studies. We identified nine studies of nuclear worker cohorts in France, Russia, the USA and the UK that had incorporated JEMs in their exposure assessments. All these JEMs were study or cohort-specific, and although broadly comparable methodologies were used in their construction, this is insufficient to enable the transfer of any one JEM to another study. Moreover there was often inadequate detail on whether, or how, JEMs were validated. JEMs have become more detailed and more quantitative, and this trend may eventually enable better comparison across, and the pooling of, studies. We conclude that JEMs have been shown to be a valuable exposure assessment methodology for imputation of missing exposure data for nuclear worker cohorts with data not missing at random. The next step forward for direct comparison or pooled analysis of complete cohorts would be the use of transparent and transferable methods.

    GSTM1, T1 and P1 are important enzymes of glutathione S-transferases (GSTs), involved in the metabolism of many endogenous and exogenous compounds. Individual genetic variation in these metabolizing enzymes may influence the metabolism of their substrates. The present study was designed to determine the genotoxic effects using DNA damage and its association with GSTM1, GSTT1, and GSTP1 (Ile105Val) genetic polymorphisms in workers occupationally exposed to organophosphate pesticides (OPs). We examined 230 subjects including 115 workers occupationally exposed to OPs and an equal number of normal healthy controls. The DNA damage was evaluated using the alkaline comet assay and genotyping was done using individual PCR or PCR-RFLP. Significantly higher DNA tail moment (TM) was observed in workers as compared to control subjects (14.41 ± 2.25 vs. 6.36 ± 1.41 tail % DNA, p<0.001). The results revealed significantly higher DNA TM in workers with GSTM1 null genotype than those with GSTM1 positive (15.18 vs. 14.15 tail % DNA, p=0.03). A significantly higher DNA TM was also observed in workers with homozygous Ile-Ile GSTP1 genotype than heterozygous (Ile-Val) and mutant (Val-Val) GSTP1 genotype (p=0.02). In conclusion, the results show that null deletion of GSTM1 and homozygote wild GSTP1 genotype could be related to inter-individual differences in DNA damage arises from the gene-environment interactions in workers occupationally exposed to OPs.

    Maintenance of a safe and stable health care infrastructure is critical to an effective mass casualty disaster response. Both secondary contamination during chemical disasters and hospital-associated infections during epidemic illness can pose substantial threats to achieving this goal. Understanding basic principles of decontamination and infection control during responses to chemical and biologic disasters can help minimize the risks to patients and health care workers. Effective decontamination following toxic chemical exposure should include both removal of contaminated clothing and decontamination of the victim's skin. Wet decontamination is the most feasible strategy in a mass casualty situation and should be performed promptly by trained personnel. In the event of an epidemic, infection prevention and control measures are based on essential principles of hand hygiene and standard precautions. Expanded precautions should be instituted as needed to target contact, droplet, and airborne routes of infectious disease transmission. Specific equipment and measures for critical care delivery may serve to decrease risk to health care workers in the event of an epidemic. Their use should be considered in developing comprehensive disaster response plans.

    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.

    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

    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.

    Abramovitz, Mimi; Zelnick, Jennifer

    2010-01-01

    Many researchers have explored how neoliberal restructuring of the workplace has reduced the standard of living and increased workplace stress among private sector employees. However, few have focused on how neoliberal restructuring of public policy has had similar effects on the public sector workforce. Using original case study research, the authors examine how two iconic pieces of neoliberal policy--the 1996 welfare reform bill in the United States and the GEAR macroeconomic policy in South Africa--affected public/nonprofit human service workers in New York City, United States, and public sector nurses in KwaZulu-Natal, South Africa. The authors argue that in both situations, despite national differences, these policies created a "double jeopardy," in which patients/clients and care workers are adversely affected by neoliberal public policy. This "double jeopardy" creates significant hardship, but also the opportunity for new social movements.

    Introduction Burnout causes physical and emotional tireness, job dissatisfaction, resulting in reduced efficiency and a feeling of alienation from colleagues. Also, job satisfaction has a major impact on job-related behaviors, such as turnover intention, absenteeism, and job performance. The aim of this study was to determine job burnout, job satisfaction rate, and related factors among health care workers in Golestan Province in Iran. Methods This cross-sectional study was conducted with 1,141 health workers in Golestan Province in northern Iran. Data were collected using a questionnaire that was comprised of four sections. It consisted of socio-economic characteristics, physical environment and facilities of health house (rural health clinic), Maslach burnout inventory, and a satisfaction questionnaire. Multi-nomial Logistic Regression was conducted to analyze the data using SPSS software, version 22. Results There were significant relationships between the intensity of job burnout and age (p education level (p = 0.027), number of children (p = 0.002), dissatisfaction with income (p education level (p = 0.016), number of children (p = 0.003), dissatisfaction with income (p < 0.001), and the physical environment of health houses (p = 0.008). There were significant relationships between job satisfaction and the satisfaction from income (p = 0.001), the physical environment of health houses (p = 0.001), and the facilities of health houses (p = 0.001). Conclusion Burnout was average among health workers, and health workers job satisfaction rate was lower than the average level in health workers. Effective interventions are recommended with regards to the unfavorable condition of job satisfaction and its relationship with job burnout.

    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

    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.

    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

    2016-01-01

    Working in residential care is associated with high demands and high stress. As a result, employees may develop symptoms of burnout. These symptoms lead to absence from work and have a negative effect on the continuity and quality of the residential care. Until now, little is known about burnout risks in child welfare workers, although children and adolescents are especially dependent on continuous relationships and healthy caregivers. A better understanding of the relationship between burnout symptoms and work satisfaction may help to identify starting points for prevention and intervention. The present study assessed symptoms of burnout in a sample of 319 social education workers in residential care in Switzerland using the burnout-screening-scales (BOSS). Work satisfaction was assessed with a newly developed questionnaire based on concepts of trauma-sensitive care. The questionnaire was tested for reliability and factorial validity in the present study. In order to estimate the relationship between burnout symptoms and work satisfaction, correlations and relative risks were calculated. Almost one fifth (18 %) of the sample showed a risk of burnout. The principal component analysis of the questionnaire on work satisfaction revealed four factors: support by superiors, participation and transparency; communication and support within the team; gratification in the work; and institutional structures and resources. All four factors as well as the total score showed significant correlations with burnout symptoms. Among employees with a comparably lower work satisfaction, the risk of burnout was 5.4 times higher than among employees with a comparably higher work satisfaction. It is discussed how work satisfaction could be promoted and how, as a result, the quality and continuity of care for the children and adolescents could be improved.

    Full Text Available Occupational exposure poses a significant risk of transmission of blood-borne pathogens to healthcare workers (HCWs. Adherence to standard precautions, awareness about post exposure prophylaxis is poor in developing countries. This retrospective study analyzes the self-reported cases of occupational exposure in a tertiary care hospital. During the study period, 105 HCWs sustained occupational exposure to blood and body fluids. Majority of the victims 36 (34.2% were interns and the clinical practice that led to the occupational exposure was withdrawal of blood (45.7%. Good infection control practices and emphasis on appropriate disposal are needed to increase the occupational safety for HCWs.

    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.

    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 Fundamento. La construcción de una cohorte poblacional de trabajadores expuestos a amianto es importante porque facilita la vigilancia, permite cumplir con la obligación ética de reconocer el origen laboral de las lesiones y contribuye al desarrollo de la investigación científica. El objetivo es describir el procedimiento que se ha seguido para identificar a los trabajadores expuestos a amianto en Navarra y conocer su respuesta a la oferta de vigilancia de la salud. Metodología. El registro de trabajadores expuestos a amianto se crea en 1999, incorporando empresas y trabajadores a partir de las fuentes de información disponibles, de ámbito nacional y regional, y se consolida con la búsqueda activa de expuestos, tanto activos como inactivos. Resultados. La cohorte es de 2.294 trabajadores, de 33 empresas; 40% están activos, la mitad trabajan fabricando vehículos de motor, 91% expuestos a crisotilo, 25% expuestos a concentraciones de fibras de amianto iguales o superior a 0,20 por cm³ de crisotilo ó 0,10 para otros. En los años 70 y 90 es cuando mayor número de trabajadores inicia la exposición; quienes comenzaron en los años 40 y 50 tienen tiempos de exposición más altos. En la vigilancia médica 72% acepta la oferta, con mayor participación de los activos. Conclusiones. La creación de la cohorte y su seguimiento han permitido reconocer el triple de casos de patología por amianto en relación con los declarados espontáneamente en los once años anteriores al programa, lo que refleja su importancia. El nivel de aceptación de la vigilancia es adecuado, dada la metodología del programa.Background. The identification of a population cohort of workers exposed to asbestos is important because it facilitates health surveillance, allowing us to fulfil the ethical obligation of recognizing the occupational origin of the illness and contributing to the development of scientific research.

    It has been noted that workplace violence most frequently occurs in psychiatric settings. The purpose of this study was to explore the workplace violence, including violence situation, victims' feeling, and the prevention strategies, on workers caring for long-term institutionalized schizophrenic patients in Taiwan. We conducted a face-to-face, in-depth, and semi-structured interview with 13 health care workers suffering from physical violence and/or sexual harassment by patients in 2002. First, the interviews were taped and/or paper-notes recorded, then transcribed, organized, and analyzed. Results found that all of the victims alleged they did not receive enough post-incident support, and more than a half of the victims could not call others for help during the violence. To avoid further attack, most victims offered prevention strategies which were considered valuable for establishing guidelines. However, some victims regarded workplace violence as inevitable and part of the job. The most common situations of workplace violence were during routine ward inspections, especially when the victims were alone. The most serious psychological harm was post-traumatic stress disorder (PTSD). In conclusion, we recommended a re-engineering of the organization to a supportive and safe working environment for prevention of workplace violence in the study hospital. PMID:17690525

    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 Aim: The documentation and assessment of general work stressors and alcohol use on mental health care workers as well as the relationship between them. Material and method: The sample consisted of 300 mental health care workers who worked in Private and Public Psychiatric Clinics and Psychiatric Hospitals of the country (Hellas. The collection of empirical material was done by using a questionnaire that included a scale of 34 questions for detecting occupational stress factors, the self-esteem scale of the Spielberger and questions about alcohol use. The statistical analysis of data was done with the statistical program SPSS version 15.0 using Student t - test, the ANOVA analysis of variance test and x2 test. Results: Higher frequency occupational stress factors appeared in Nurses rather than Doctors as well as in employees in Private Psychiatric Clinics rather than employees in the Public sector. The fact that Nurses have higher frequency in stressors rather than Doctors is reflected in measurements of anxiety, as a state as well as a personality trait. Also the employees of Private Psychiatric Clinics exhibit greater indicator of anxiety as a personality trait than the employees of the Public sector. Regarding alcohol use (concept of efficiency and normal consumption quantity it was found to be positively associated with the age of the employees. Also the concept of the effectiveness of alcohol in tackling work stress is associated with some occupational stress factors (dangerous conditions of work, rolling working hours. Conclusions: Factors such as specialty and the type of workplace (Public, Private sector affect the stress experienced by the mental health professional. The view of alcohol as a means of relieving working stress is associated with certain stressors of work and the worker's age.

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.

    The mutagenicity of urinary extracts and the excretion of PAH from workers occupationally exposed to coal tar pitch volatiles in an anode plant were analyzed. Mutagenicity of the urinary extracts was measured by means of the plate test using S. typhimurium strain TA 98. After concentration, hydrolysis and reduction of the urine samples, PAH levels were measured by high resolution gas chromatography/mass spectrometry. No significant difference was found in the mutagenicity of the urinary extracts of non-smokers occupationally exposed to PAH as compared with the controls. Low PAH concentrations were found in the urine of the exposed subjects, which lends further support to the negative results obtained with the Ames' test. The increase of urinary PAH excretion, in relation to occupational exposure, was mainly due to the less mutagenic, low molecular weight compounds.

    This study examined the approaches to learning of a cohort (n=76) of National Vocational Qualification (NVQ) Care Award candidates using the Approaches and Study Skills Inventory for Students. The NVQ candidates were support workers (SWs) (sometimes called care assistants) employed in United Kingdom (UK) care homes for older people. The aim was to identify SWs' approaches to learning and to determine whether or not a preparatory six-week College-based course had any impact on these approaches. The findings were encouraging. The course had a positive impact with a statistically significant increase in orientation towards a deep learning approach, which is associated with desirable learning outcomes as well as self-directed and lifelong learning skills. The UK government recognises that lifelong learning enables people to continually develop their talents, thereby enhancing local communities and contributing to a civilised, cohesive society. In a health care environment, adopting a deep approach is likely to be beneficial. Those who use evidence to inform practice, who are able to relate elements of what they are taught to their working experiences and who are able to adapt to meet new challenges, are more likely to enhance their practice and become more effective carers.

    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.

Objectives: The aim was to assess awareness, practice of selected high risk health care workers (HCW regarding risk for contracting hepatitis B and self-reported vaccination status. Materials and Methods: A cross-sectional study was conducted among 300 selected HCW of AGMC and GBP Hospital, TMC and Dr BRAM Teaching Hospital and Indira Gandhi Memorial Hospital, Agartala during Jan to March 2014. Results: About 72.1% respondents were females with overall mean age of 24.10 (standard deviation ±7.011. 67.5% females were within the age group of 18-23 years. Majority (70.4% of the participants were nursing students and Hindu (92.5% nuclear families (54.6%. Majority (69.3% of them were aware that hepatitis B transmission was possible through unsafe sex, infected blood/body fluid, contaminated syringe, needle and scalpel, 19.6% knew through infected blood and body fluids, 5.7% knew through contaminated syringe, needle and scalpel, 1.8% knew through unsafe sex. 59.3% had a history of contact with known hepatitis B case. 62.2% were vaccinated with three doses of hepatitis B vaccine. Majority of the participants had exposed to hepatitis B positive case while at work (P = 0.001. The exposed persons with known hepatitis B cases have consulted doctor, vaccinated and treated with medicines (P = 0.002; used needle destroyer (P = 0.012; vaccinated with 3 doses of hepatitis B vaccine (P = 0.001; and used sterile gloves while performing work (P = 0.000, especially while dealing with blood and body fluid. Conclusion: In spite of having good knowledge, the way they practice for prevention of hepatitis B infections were inadequate and need further improvement.

    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.

    Diisocyanates, highly reactive monomers which cross-link polyurethane, are the most widely recognized causes of occupational asthma. Many exposed workers are end-users, including autobody spray painters who form a large population at risk. Neither the factors which determine incidence rate nor strategies for control have been adequately studied in this setting. We have conducted a cross-sectional survey of 23 (about one in five) autobody shops in the New Haven area to determine the feasibility of clinical epidemiological studies in this population. Among 102 workers, there was a high rate of airway symptoms consistent with occupational asthma (19.6%). Symptoms were most prevalent among those with the greatest opportunity for exposure (dedicated spray painters) and least among office workers; part-time painters had intermediate rates. Atopy was not associated with risk while smoking seemed to correlate with symptoms. Regular use of air-supplied respirators appeared to be associated with lower risk among workers who painted part- or full-time. We were unable to validate the questionnaire responses with peak expiratory flow record data attempted on a 1/3 sample of the workers. Despite intensive training and effort, subject compliance was limited. Among those who provided adequate data (24 of 38), only two demonstrated unequivocal evidence of labile airways; two others demonstrated lesser changes consistent with an occupational effect on flow rates. There was no clear association between these findings and either questionnaire responses or exposure classification. Overall, the survey suggests that there is a high prevalence of airway symptoms among workers in autobody shops, at least in part due to work-related asthma. However, there is need for both methodological and substantive research in this setting to document rates of occupational asthma and to develop a scientific basis for its effective control.

    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

    To determine risk factor for H9N2 avian influenza virus (AIV) infection, a serological surveillance among both occupational poultry-exposed (OPE) workers and general humans was carried out using both haemagglutination inhibition (HI) and microneutralization (MN) assays in Tai'an, China, between 2011 and 2013. At baseline, the positive rate of anti-H9 antibody (HI and MN titers ≥40) among OPE workers (51/600, 8.5%) was significantly higher than that among the general population (11/600, 1.8%). The result indicated that occupational exposure to chicken flocks was an important risk factor for H9N2 AIV infection. J. Med. Virol. 88:1453-1456, 2016. © 2016 Wiley Periodicals, Inc. PMID:26816053

    Full Text Available Objectives: Viral hepatitis is the second most often identified infectious illness acquired at work and it is mostly registered among health care personnel. This group of workers is at greater risk of exposure to blood and bloodborne pathogens, including hepatitis B and C viruses. The aims of this study were to evaluate the efficacy of methods promoting work safety in healthcare settings, to assess the frequency of exposures in the last 12 months prior to the study and to determine a rate of reporting them to appropriate authorities. Methods: A total of 1138 Polish healthcare workers were interviewed during the study period (between 2009 and 2010. Results: Sustaining accidental occupational percutaneous exposure during last 12 months was declared by 242 workers (21% of the whole group. Only in 146 cases these incidents were reported to authorities. Exposure incidents were associated with self-perception of high risk of exposure (OR = 3.69, p = 0.0027, employment in out-patient (vs. hospital-based healthcare setting (OR = 1.71, p = 0.0089, conviction that the level of information about bloodborne infections conveyed at work was insufficient, lack of both exposure reporting system and knowledge about the ways of reporting. Conclusions: Despite the different established proposals of the post-exposure procedures, it turns out that particularly in small, not providing 24 hours service healthcare settings these procedures are not known or are not respected. More attention should be given to education, especially in regard to the risk of infection, advantages of post-exposure prophylaxis and reporting exposure incidents. Med Pr 2013;64(1:1–10

  1. Study of hepatitis b among different categories of health care workers

    International Nuclear Information System (INIS)

    Objective: To estimate the frequency of hepatitis B virus (HBV) infection among different categories of health care workers (HCWs) so as to identify groups and areas requiring special attention for the prevention of occupational transmission of blood borne infections. Design: A cross-sectional study. Place and Duration of Study: The study was conducted in Bir Hospital, the central referral hospital of Nepal from December 2001 to February 2002. Patients and Methods: A total of 145 HCWs were selected by random allocation and blood samples were tested for HBV surface antigen (HBsAg), surface antibody (anti-HBs) and core antibody (anti-HBc). Multivariate analysis was done, including calculation of odd ratios for HBV infection by each variable of interest, like age, sex, HCW category, history of blood transfusion and vaccination status. Results: Anti-HBc was positive in 14.5% and HBsAg in 1.4% of HCWs. 20.9% of non-professional staff, 19.2% of nurses, 5.6% of laboratory workers and 3.1 % of doctors had evidence of past or present HBV infection. 48.9% of HCWs, with only 16.7% of laboratory workers and 27.9% of non-professional staff, had received a full course of HBV vaccination. The significant risk factors associated with past or present HBV infection were lack of hepatitis B vaccination (p<0.05) and two HCW categories-nurses (p<0.05) and non-professional staff, who clean the used instruments (p<0.05). Conclusion: Apart from lack of hepatitis B vaccination, nurses and non-professional staff on their own were found to be significantly more susceptible to HBV infection than others. This highlights the need to implement the internationally recommended measures to protect HCWs from blood borne infections. (author)

    Full Text Available South Africa is renowned for having a progressive Constitution with strong protection of human rights, including protection for persons using the public health system. While significant recent discourse and jurisprudence have focused on the rights of patients, the situation and rights of providers of health care services have not been adequately ventilated. This paper attempts to foreground the position of the human resources personnel located at the centre of the roll-out of the government's ambitious programme of anti-retroviral (ARV therapy.The HIV/AIDS epidemic represents a major public health crisis in our country and, inasmuch as various critical policies and programmes have been devised in response, the key to a successful outcome lies in the hands of the health care professionals tasked with implementing such strategies. Often pilloried by the public, our health care workers (HCWs face an almost Herculean task of turning the tide on the epidemic. Unless the rights of HCWs are recognised and their needs adequately addressed, the best laid plans of government will be at risk.This contribution attempts to identify and analyse the critical challenges confronting HCWs at the coalface of the HIV/AIDS treatment programme, in particular the extent to which their own rights are under threat, and offers recommendations to remedy the situation in order to ensure the successful realisation of the ARV rollout.

    Setting: Health care facilities in Dar es Salaam, Pwani, and Arusha, Tanzania. Objective: To assess health care worker (HCW) knowledge and practices 1 year after specialized training in childhood tuberculosis (TB). Design: Using a standardized survey, we interviewed a convenience sample of HCWs providing both general and specialized care to children. Results: We interviewed 117 HCWs in TB clinics, maternal and child health clinics, human immunodeficiency virus (HIV) clinics, out-patient departments, and pediatric in-patient wards at 12 facilities. A total of 81 HCWs (62% of nurses, 74% of clinicians) reported having attended the national childhood TB training course. Most HCWs responded correctly to questions on childhood TB diagnosis, treatment, and TB-HIV co-management, regardless of training history. Most HCWs reported that they routinely obtain chest radiographs, HIV testing, and a TB contact history when evaluating children for TB. Less than half of HCWs reported routinely obtaining sputum for mycobacterial culture or performing a tuberculin skin test. Three times as many trained as untrained HCWs reported having ever prescribed isoniazid preventive therapy (IPT) to a child (P < 0.05). Conclusion: In general, levels of childhood TB knowledge were high and practices were in accordance with national guidance. Specific gaps in diagnosis, treatment and use of IPT were identified for future focused training. PMID:26400701

    Full Text Available Access to health care is a crucial determinant of health. Yet, even within settings that purport to provide universal health coverage (UHC, sex workers' experiences reveal systematic, institutionally ingrained barriers to appropriate quality health care. The aim of this study was to assess prevalence and correlates of institutional barriers to care among sex workers in a setting with UHC.Data was drawn from an ongoing community-based, prospective cohort of women sex workers in Vancouver, Canada (An Evaluation of Sex Workers' Health Access. Multivariable logistic regression analyses, using generalized estimating equations (GEE, were employed to longitudinally investigate correlates of institutional barriers to care over a 44-month follow-up period (January 2010-August 2013.In total, 723 sex workers were included, contributing to 2506 observations. Over the study period, 509 (70.4% women reported one or more institutional barriers to care. The most commonly reported institutional barriers to care were long wait times (54.6%, limited hours of operation (36.5%, and perceived disrespect by health care providers (26.1%.

    Full Text Available OBJECTIVE: To verify the prevalence and factors associated with vaccination against hepatitis B among Primary Health Care workers in Montes Claros/MG. METHOD: A cross-sectional, analytic study was undertaken. Data were collected through a form, which contained sociodemographic, occupational, general health and behavioral variables. Associations were investigated through bivariate analysis and Poisson's multivariate regression, using SPSS 17.0. RESULTS: 95.5% answered the question about vaccination; 47.5% did not complete the vaccination scheme. The prevalence of vaccinated professionals was lower among older workers, who were hired, did not participate in occupational health updates and consumed alcohol. Prevalence levels were higher among professionals with more years of education and who reported contact with piercing and cutting instruments . CONCLUSIONS: Professional education, knowledge and perception of infection risks are important determinants of the vaccination scheme. Instability at work may lead to negligence and negligent behaviors may repeat themselves. The characterization of professionals who did not get vaccinated will direct educative actions in occupational health.

    Female genital mutilation/cutting (FGM/C) is a traditional practice originating in Africa. Its worst forms cause irreparable harm to girls and women and have no medical justification. Based on a literature review of global responses to FGM/C and conversations with Australian women who migrated from FGM/C practicing countries, this paper provides some background on FGM/C and its epidemiology, outlining its prevalence, types, and health risks and complications for women and girls. It discusses risk-prevention strategies, first, for health practitioners in identifying, screening, and supporting women affected by FGM/C and, second, for welfare and social workers and health care professionals to identify, work with, and prevent girls from being cut. Consistent with international trends in addressing the risks of FGM/C, the paper suggests practice responses for coordinated responses between professionals, communities from practicing countries, and governments of different countries.

    Full Text Available Background: Community health workers (CHWs have been employed in a number of low- and middle-income countries as part of primary health care strategies, but the packages vary across and even within countries. The experiences and motivations of a multipurpose CHW in providing maternal and newborn health have not been well described. Objective: This study examined the perceptions of community members and experiences of CHWs around promoting maternal and newborn care practices, and the self-identified factors that influence the performance of CHWs so as to inform future study design and programme implementation. Design: Data were collected using in-depth interviews with six local council leaders, ten health workers/CHW supervisors, and eight mothers. We conducted four focus group discussions with CHWs. Respondents included 14 urban and 18 rural CHWs. Key themes explored included the experience of CHWs according to their various roles, and the facilitators and barriers they encounter in their work particular to provision of maternal and newborn care. Qualitative data were analysed using manifest content analysis methods. Results: CHWs were highly appreciated in the community and seen as important contributors to maternal and newborn health at grassroots level. Factors that positively influence CHWs included being selected by and trained in the community; being trained in problem-solving skills; being deployed immediately after training with participation of local leaders; frequent supervision; and having a strengthened and responsive supply of services to which families can be referred. CHWs made use of social networks to identify pregnant and newly delivered women, and were able to target men and the wider family during health education activities. Intrinsic motivators (e.g. community appreciation and the prestige of being ‘a doctor’, monetary (such as a small transport allowance, and material incentives (e.g. bicycles, bags were also important

    Fear of HIV infection and its consequences may affect the willingness and capacity of health care workers to provide good quality care for people with HIV/AIDS (PWHAs). The study was founded on the proposition that self-efficacy may mediate the attitudinal disposition of health care workers related to provision of care to PWHAs. Two hundred and ten physicians (n = 103) and nurses (n = 107) sampled from the University College Hospital, Ibadan, Nigeria, responded (48% response rate) to a questionnaire which addressed self-efficacy relating to HIV/AIDS, knowledge about HIV/AIDS and treatment of and attitudes towards HIV/AIDS patients. Attitude questions included items on fear of HIV infection, futility in providing care for HIV patients, distress in caring for the patient who is likely to die and willingness to care for PWHAs. The major finding was a significant association between reported high selfefficacy and less fear of acquiring HIV, less futility in providing care for PWHAs and increased willingness to provide such care. More years of education was associated with higher willingness to care, less fear associated with care as well as lower perceived futility related to the care of PWHAs. Female gender was significantly related to the perception of futility related to the care of PWHAs. There was no significant relationship between self-efficacy and knowledge about HIV/AIDS. The findings have significant implications for hospital care for PWHAs and suggest that self-efficacy, rather than knowledge about HIV/AIDS may be important in mediating attitudes towards PWHAs and also in developing intervention programmes aimed at helping health care providers to reframe their attitudes.

In this direction the epidemiological data on sharps injury events, becomes an essential pre-requisite. Objectives: 1 To study the prevalence and associated factors of Needle Stick Injuries (NSI among the health care workers of our hospital. 2 To assess the level of awareness of the health care workers regarding NSI. Materials and methods: A cross-sectional study was conducted and data was collected using a anonymous pre-tested structured questionnaire among the respondents (441 of the health care workers of a tertiary care rural hospital. Statistical analysis was done using chi square test in Open Epi version 2. Results: About 57% (252 out of 441 of the Health Care Workers (HCW had at least one episode of NSI in the preceding 12 months .Majority were Nurses (81%.The commonest devices involved was suturing needle (41% and hypodermic needles (44%.Majority of the NSI (46 % occurred during use of needle on the patient. About (85% of the HCW didn’t report the injury. Hepatitis B vaccination rate was very low among HCW other than doctors. Doctors had better knowledge on all counts compared to other categories of HCW. A majority of the HCW (92% were not aware of the reporting system existing in their hospital. Conclusions: The present study showed a high occurrence of NSI in HCWs especially among nurses followed by doctors and a high rate of ignorance and apathy among other categories. These issues need to be addressed, through appropriate education and other interventional strategies by the hospital infection control committee.

    Alex Little

    Full Text Available BACKGROUND: Mobile health applications are complex interventions that essentially require changes to the behavior of health care professionals who will use them and changes to systems or processes in delivery of care. Our aim has been to meet the technical needs of Health Extension Workers (HEWs and midwives for maternal health using appropriate mobile technologies tools. METHODS: We have developed and evaluated a set of appropriate smartphone health applications using open source components, including a local language adapted data collection tool, health worker and manager user-friendly dashboard analytics and maternal-newborn protocols. This is an eighteen month follow-up of an ongoing observational research study in the northern of Ethiopia involving two districts, twenty HEWs, and twelve midwives. RESULTS: Most health workers rapidly learned how to use and became comfortable with the touch screen devices so only limited technical support was needed. Unrestricted use of smartphones generated a strong sense of ownership and empowerment among the health workers. Ownership of the phones was a strong motivator for the health workers, who recognised the value and usefulness of the devices, so took care to look after them. A low level of smartphones breakage (8.3%,3 from 36 and loss (2.7% were reported. Each health worker made an average of 160 mins of voice calls and downloaded 27Mb of data per month, however, we found very low usage of short message service (less than 3 per month. CONCLUSIONS: Although it is too early to show a direct link between mobile technologies and health outcomes, mobile technologies allow health managers to more quickly and reliably have access to data which can help identify where there issues in the service delivery. Achieving a strong sense of ownership and empowerment among health workers is a prerequisite for a successful introduction of any mobile health program.

    Nuttman-Shwartz, Orit

    2015-10-01

    This article proposes a new concept, shared resilience in a traumatic reality (SRTR), which refers to trauma workers in shared reality situations. Based on the literature that emphasizes the positive effects of exposure to traumatic events for workers in this field, this article expands the perception of shared traumatic situations and examines the ability of trauma workers to cope, to show resilience, and to grow as a result of the mutual relationship with their clients. The literature review presents a variety of terms referring to the positive effects of working with trauma survivors on therapists as a basis for the new concept proposed here. These terms highlight the importance of empathic mutual aid relationships, which are a basic component for promoting resilience in a shared traumatic reality. The relative nature of shared resilience is discussed, bearing in mind that resilience can be manifested as emotions, behaviors, and conceptions. Various findings relating to shared resilience in traumatic situations are reviewed, and recommendations for research, practice, and policy are offered. PMID:25427830

    Full Text Available Abstract Background Burnout has important clinical and professional implications among health care workers, with high levels of burnout documented in oncology staff. The aim of this study was to ascertain how well a brief single-item measure could be used to screen for burnout in the Australian oncology workforce. Methods During 2007, 1322 members of the Clinical Oncological Society of Australia were invited to participate in a cross-sectional nationwide survey; 740 (56% of eligible members consented and completed the survey. Data from the 638 consenting members who reported that their work involved direct patient contact were included in the secondary analyses reported in this paper. Burnout was assessed using the MBI Human Services Survey Emotional Exhaustion sub-scale and a single-item self-defined burnout scale. Results Emotional exhaustion was "high" in 33% of the sample when assessed by the psychometrically validated MBI. The single-item burnout measure identified 28% of the sample who classified themselves as "definitely burning out", "having persistent symptoms of burnout", or "completely burned out". MBI Emotional Exhaustion was significantly correlated with the single-item burnout measure (r = 0.68, p 2 of 0.5 (p Conclusions The moderate to high correlation between the single-item self-defined burnout measure and the emotional exhaustion component of burnout suggest that this single item can effectively screen for burnout in health care settings which are time-poor for assessing burnout more comprehensively.

    Workplace stress (WS) has been found to affect job satisfaction (JS), performance, and turnover intentions (TIs) in developed countries, but there is little evidence from other countries and especially rural areas. In rural Taiwan, especially, there is an insufficient health care workforce, and the situation is getting worse. To demonstrate the relationship, we used a cross-sectional structured questionnaire, and data from 344 licensed professionals in 1 rural regional hospital were analyzed using the structural equation model. The results showed that WS had a positive effect on both TI and job performance (JP) but a negative effect on satisfaction. JS did improve performance. For the staff with an external locus of control, stress affected JP and satisfaction significantly. For the staff with lower perceived job characteristics, JS affected performance significantly. The strategies to decrease stress relating to work load, role conflict, family factors, and working environment should be focused and implemented urgently to lower the turnover rate of health care workers in rural Taiwan.

    Aim: Latent tuberculosis infections (LTBI) contain a significant reservoir for future epidemics. Screening of health care workers (HCWs) in a high-risk tuberculosis (TB) environment is an important strategy in TB control. The study aimed to assess the prevalence of LTBI among high risk Egyptian HCWs and to assess infection associated risk factors. Methods: Fifty-two HCWs who work at intensive care unit (ICU), bronchoscopy unit, and chest diseases department were tested for LTBI using both tuberculin skin test (TST) and Quantiferon TB Gold in-tube test (QFT). Risk factors for infection, knowledge of HCWs towards different aspects of TB infection and agreement between TST and QFT were also evaluated. Results: Prevalence of LTBI in this study was 13.5% by QFT and TST. It was 13.6% by TST alone and 10.3% by QFT alone. There was good concordance between both tests (Kappa=0.713). There was a statistically significant association between prevalence of LTBI and age of staff ≥30 yr (p=0.002), period of working experience (p=0.006) and working at the Bronchoscopy Unit (p=0.001). The total knowledge of HCWs towards different aspects of TB infection was generally good. Conclusion: Although the participants in the current study were among high risk HCWs, the prevalence of LTBI was low. Bacille Calmette-Guerin (BCG) vaccination, young age, short employment duration, good knowledge and a good infection control were the predictors of low risk of contracting TB at our hospitals. The risk of TB infection in resource-limited countries can be reduced with simple continuous educational and administrative infection control programmes. PMID:27777875

  12. Correlation between gene polymorphisms of IL-2, IL-6 and TNF-α in workers exposed to rare earth dust and their lung ventilation function

    International Nuclear Information System (INIS)

    Objective: To study the relationship between lung ventilation function of workers exposed to rare earth dust and their IL-2, IL-6 and TNF-α gene polymorphism. Methods: TNF-α gene polymorphism were identified by RFLP-PCR, IL-2 and IL-6 gene polymorphisms were identified by PCR-CTPP analysis. Lung ventilation function was deteced by instrument of ventilation function. Results: Compared with controls, there was no statistic significance in frequencies distribution of TNF-α gene polymorphism (χ2=4.03, P>0.05), IL-2 gene polymorphism (χ2=2.21, P>0.05) and IL-6 gene polymorphism (χ2=1.05, P>0.05). Compared with IL-2 gene wild type, IL-2 homozygote type increased the risk of lung ventilation dysfunction by 4.29 folds (95% CI 1.09 ∼ 16.9). Conclusions: Compared with controls,incidence of ventilation function of workers exposed to rare earth dust is in ascending trend. IL-2 (G/G) gene type induces more serious inflammation reaction than the others. (authors)

    Full Text Available Objective: To explore the association of the methylation status of MGMT and hMLH1 with chromosome damage induced by vinyl chloride monomer (VCM. Materials and Methods: Methylation of MGMT and hMLH1 was measured in 101 VCM-exposed workers by methylation-specifi c PCR. Chromosome damage in peripheral blood lymphocytes was measured by the cytokinesis-block micronucleus assay. The subjects were divided into chromosome damaged and non-damaged groups based on the normal reference value of micronuclei frequencies determined for two control groups. Results: MGMT promoter methylation was detectable in 5 out of 49 chromosome damaged subjects, but not in the chromosome non-damaged subjects; there was a signifi cant difference in MGMT methylation between the two groups (p < 0.05. Conclusions: We detected aberrant promoter methylation of MGMT in a small number of chromosome damaged VCM-exposed workers, but not in the chromosome non-damaged subjects. This preliminary observation warrants further investigation in a larger study.

    Full Text Available Introduction: Gujarat State AIDS Control Society with support from UNICEF Gujarat has initiated as unique project for prevention of HIV /AIDS at rural set up since 2008, which is known as Link Workers’ scheme. Link Workers (LWs are working in each cluster of villages around a 5,000+ population village which will serve as the node for intervention. They are supported in their work by village level volunteers selected from the available groups in the community. Methodology: 140 Link workers and 70 volunteers from 70 villages of 14 blocks of district Surat were invited for the study. Due to few vacant posts, total 183 participants took part in the study; out of these 117 were link workers (LWs while 66 were volunteers. Their Knowledge regarding HIV/AIDS and STI were assessed on a predesigned pretested semi structured study tool. Result: 96.59% link workers and 93.44% volunteers had knowledge about condom use as a method of preventing HIV infection. The concern issue is that only 11.11% LWs and 13.64% volunteers revealed that HIV testing during ANC check up can also prevent HIV transmission from mother to child, inspite of receiving induction training. Only 74.36% LWs and 68.31% volunteers were able to tell about three or more HIV preventive methods. Recommendations: Refresher training and exposure visit to HIV care centres are needed for these workers to strengthen their knowledge. [National J of Med Res 2012; 2(2.000: 173-175

    2016-01-01

    Supportive housing schemes were historically aimed to provide group accommodation for older adults. With the aging of residents, facilities were required to enable them to receive care services in order to allow them to age in place. Thus, different countries and different facilities developed different models of housing with care, reflecting cultural and policy diversities. Despite all of the different models, there are many commonalities among the supportive housing schemes across countries. These include provision of dwelling units and care services provided by either the facility or by external agencies. The aims of this article are threefold: to describe the historical development of the ever-evolving supportive care housing phenomena; to point at variations in models of housing and care within the international context; and to present a new Israeli model that enables residents to privately hire live-in care workers to meet their care needs. This is a unique model in the international context that has not been reported before. The article describes the main ideas of the new model and discusses the challenges that it raises and pinpoints the unresolved issues associated with the presence of live-in care workers employed by residents of sheltered housing that should be addressed.

    Two men reported previously with vitiligo after occupational exposure to hydroquinone monomethyl ether (HMME) have been reviewed after eight years. Repigmentation of significant degree was found in one man and of limited degree in the other. One hundred and sixty-nine men in the same works have been screened with Wood's light for evidence of vitiligo. No cases were found in the 148 men exposed to HMME (colleagues who screened 100 men exposed to HMME in two other factories also found no case) or in the 129 who had been exposed to paratertiary-amyl-phenol. Loss of light reflection on Wood's light examination was observed in 13 men due to scars or to other skin disorders.

    In this study we discuss the measures of providing care to young workers with mental health disturbance by analyzing the cases of workers who had taken sick leave due to mental health disturbance. We analyzed 36 cases, collected from 11 occupational physicians, of workers who had taken sick leave due to mental health disturbance, and discuss measures for providing care to such young workers. We organized and classified data containing the details of the care provided to the workers and analyzed the main aspects and problems in providing it. We compared two age groups of workers: a below age 30 group, and an age 30 and above group. We observed that occupational nurses were more frequently the primary persons who dealt with workplace consultations in the below age 30 group (before sick leave: 38.9%; during sick leave: 38.9%) compared to the age 30 and above group (before sick leave: 16.7%, during sick leave: 11.1%). Most of the case providers expressed the opinion that a support system is necessary to help the workers return to work and it is an important factor in providing care to workers who have taken sick leave due to mental health disturbance. Coordination with the families of the workers was also important in the below age 30 group. It might be difficult to assign young workers to suitable workplaces or duties because of their inadequate job skills, lack of sufficient experience, and influence of personal factors on mental health. Our results suggest that it is important to provide appropriate care for young workers with mental health disturbance, such as support by occupational nurses, and to strengthen the collaboration between their families and the workplace staff.

    Full Text Available Introduction: In South Africa, there are renewed efforts to strengthen primary health care and community health worker (CHW programmes. This article examines three South African CHW programmes, a small local non-governmental organisation (NGO, a local satellite of a national NGO, and a government-initiated service, that provide a range of services from home-based care, childcare, and health promotion to assist clients in overcoming poverty-related barriers to health care. Methods: The comparative case studies, located in Eastern Cape and Gauteng, were investigated using qualitative methods. Thematic analysis was used to identify factors that constrain and enable outreach services to improve access to care. Results: The local satellite (of a national NGO, successful in addressing multi-dimensional barriers to care, provided CHWs with continuous training focused on the social determinants of ill-health, regular context-related supervision, and resources such as travel and cell-phone allowances. These workers engaged with, and linked their clients to, agencies in a wide range of sectors. Relationships with participatory structures at community level stimulated coordinated responses from service providers. In contrast, an absence of these elements curtailed the ability of CHWs in the small NGO and government-initiated service to provide effective outreach services or to improve access to care. Conclusion: Significant investment in resources, training, and support can enable CHWs to address barriers to care by negotiating with poorly functioning government services and community participation structures.

  20. Bio-toxicological supervision op workers exposed to lead poisoning hazard. Systematic examination of amino acids, in urine and plasma

    International Nuclear Information System (INIS)

    A bio-toxicological chart was established for the workers in a firm handling lead. The known facts concerning professional lead poisoning are outlined, after which the importance of lead work in a nuclear center is discussed. The work station of each man is described and the results of analyses made during atmospheric checks on the site are given with sampling techniques. Since the biological chart is centered on the chromatographic exploration of amino acids in blood and urine, the analytical technique used is described and the different technical modifications made to the standard technique reported. The results obtained on reference subjects are compared with those found in the specialized literature. The results found in lead workers are then presented in the form of histograms, which better illustrate the differences observed with respect to the reference subjects. An hematological and toxicological balance-sheet is drawn up and the correlation existing between the results of coproporphyrine, lead and delta-aminolevulinic acid analyses in urine is checked. Biological detection of lead-poisoning has the advantage of providing an early diagnosis, thus enabling the works doctor to forestall the effects of this professional disease before any clinical symptoms appear.

    In the 1950s the Pneumoconiosis Field Research (PFR) programme was set up to study the health of British coalworkers. Studies included regular health surveys, an intensive characterisation of workers' individual exposures, and entry to a cohort followed up to the present for cause-specific mortality. This study reports on analyses of cause-specific mortality in a cohort of almost 18,000 men from 10 collieries. External analyses used standardised mortality ratios, comparing observed mortality with reference rates from the regions in which the pits were situated. Causes investigated include lung and stomach cancers, nonmalignant respiratory diseases, and cardiovascular endpoints. Internal analyses used Cox regression models with time-dependent exposures adjusting for the confounding effects of age, smoking, cohort entry date and regional differences in population mortality rates. Several causes showed evidence of a healthy worker effect early in the follow-up, with a deficit in the SMR diminishing over time. For most of the causes there was a significant excess in the latter part of follow-up. Internal analyses found evidence of an association between increased risks of lung cancer and increased quartz exposure, particularly at a lag of 15 years. Risks of mortality from non-malignant respiratory disease, and specifically chronic obstructive pulmonary disease and pneumoconiosis, showed increases with increased exposure to respirable dust. 60 refs.

    This study engages with the culture-centered approach (CCA) to explore Chinese immigrant restaurant workers' perception of the U.S. health care system and their interactions with the health care system in interpreting meanings of health. Chinese restaurant workers are marginalized because of their struggles on the job, their immigrant identity, and their negotiations with the structural contexts of occupation, migration status, and culture. In-depth interviews were conducted with 18 Chinese immigrant restaurant workers that lasted an average of 1.5 hours each, and were audiotaped. Interviews with participants highlighted critical issues in access to health care and the struggles experienced by restaurant workers in securing access to health, understood in the context of work. Critical to the workers' discourse is the acknowledgment of structural constraints such as lack of insurance coverage, immigration status, and lack of understanding of how the U.S. health care system works.

    Full Text Available According to existing literature, ancillary health care workers (AHCWs often do not meet the health care needs of patients with physical disabilities (physically disabled patients in a homebased environment, because of inadequate training programmes. The purpose of this research study was to explore the health care needs of physically disabled patients in long-term, home-based care in the northern suburbs of Johannesburg and, based on results, to offer recommendations for the training of AHCWs. Qualitative, exploratory, descriptive and contextual means were employed in data collection and analysis. The population consisted of eight physically disabled participants who employed an AHCW to assist them with their long-term home care. Purposive sampling was used with subsequent snowballing to identify further participants for the study. Individual interviews were conducted, where participants had to answer the questions (1‘What are your health care needs?’ and(2 ‘How should these be met?’ Data saturation was ensured, after which Tesch’s method of data analysis was followed. Three categories of health care needs were identified (1 physical health care needs, (2 interpersonal relationship needs and (3 social needs, and 12 themes were derived from these categories. These categories of health care needs should be addressed in the training of AHCWs.From the themes, recommendations were described for the training of AHCWs on the health care needs of the home-based physically disabled patients. The AHCW should assist in the adaptation of the environment to the patient’s individual needs, and should use knowledge and critical thinking skills to ensure a patient-centred care setting.

    Full Text Available Abstract Objective To study the association of workplaces and recent onset latent tuberculosis (LTB in health care workers (HCW. Methods A case-control study was conducted at Srinagarind Hospital, Khon Kaen University, Thailand. We recruited HCW who had results of tuberculin test within 2 consecutive years from 2001–2008 and also had fixed workplaces (working hours more than 40 hours/week. Cases were subjects with tuberculin conversion, while controls were subjects with negative results of tuberculin test in two consecutive years. Tuberculin conversion was defined if a subject had a negative baseline tuberculin test and a positive tuberculin test in the next consecutive years. Baseline characteristics, workplaces (office, in-patient unit, out-patient unit, intensive care, operating room, and laboratory unit, tuberculosis related variables, and prevention strategies were studied. Multiple logistic regression analysis was used to identify predictors for tuberculin conversion. Results There were 624 subjects who met the criteria and 163 subjects had tuberculin conversion (26.1%; case group. The median age and male/female ratio of both groups were 39 years old and about 1:4. The cases group had higher percentage of subjects who worked at in- and out-patient department (30.7 vs 20.2 and 17.2 vs 12.2, respectively, had history of tuberculosis exposure in the past year (32.1 vs 16.1, and had history of prevention by any method and by surgical mask (49.4 vs 37.0 and 54.3 vs 38.3, respectively.

    2004-01-01

    Recent legislation regarding the safety of workers aboard fishing vessels requires the appointment by ship owners of a Reference Physician in charge of health surveillance, preventive inspections and related tasks. As maritime workers, especially fishermen, have always been excluded from legal protection of occupational health, there are no exhaustive data on the incidence of their occupational disease. Several epidemiological studies of fishermen have evidenced a high prevalence and incidence of occupational conditions, among which noise-related hypoacousia. We report data of a phonometric survey conducted aboard six fishing vessels carrying a crew of less than six fishing in the mid-Adriatic. Measurements were performed during fishing and navigation aboard five vessels fitted with a fixed-pitch propeller and during fishing only aboard one vessel fitted with an controllable pitch propeller. Measurements were conducted: 1) in the engine rooms; 2) in the work area on deck; 3) at the winch; 4) in the wheelhouse; 5) in the mess-room and kitchen; 6) in the sleeping quarters. Results show that the equivalent sound pressure level in the engine rooms consistently exceeded 90 dBA on all vessels. The speed of the vessels fitted with the fixed-pitch propeller is 3-4 knots in the fishing phase and around 10 knots during navigation to and from the fishing grounds; noise emission is lower with the former regimen because of the smaller number of engine revolutions per minute. Our survey demonstrated considerably different noise levels in the various areas of vessels. One key element in workers' exposure, the tasks assigned and the environmental working conditions is of course the type of fishing in which the vessel is engaged. Further phonometric studies are required to assess the daily level of exposure per crew member, which represents the reference for the noise-related risk of each subject. Knowledge of the sound pressure levels in the work environment and the length of

    Injuries caused by unsafe manual handling of patients are a major source of ill health in health care workers. The present study evaluated the ability of 4 classes of variable to predict use of a hoist when moving a heavily dependent patient. Variables examined were occupational role characteristics, such as hours of work and type of shift worked; biographics, including age and height; aspects of occupational context, such as number of hoists available and number of patients; and motivational variables specified by the theory of planned behavior (Ajzen, 1985) and protection motivation theory (Rogers, 1983). Regression analyses showed that background and social-cognitive variables were able to account for 59% of variance in intention to use a hoist and 41% of variance in use of the hoist assessed 6 weeks later. Height, hoist availability, coworker injunctive norm, perceived behavioral control, response cost, response benefits, and social and physical costs of not using the hoist each explained independent variance in motivation to use a hoist at work.

    Full Text Available Susan Costello School of Global, Urban and Social Studies, RMIT University, Melbourne, VIC, Australia Abstract: Female genital mutilation/cutting (FGM/C is a traditional practice originating in Africa. Its worst forms cause irreparable harm to girls and women and have no medical justification. Based on a literature review of global responses to FGM/C and conversations with Australian women who migrated from FGM/C practicing countries, this paper provides some background on FGM/C and its epidemiology, outlining its prevalence, types, and health risks and complications for women and girls. It discusses risk-prevention strategies, first, for health practitioners in identifying, screening, and supporting women affected by FGM/C and, second, for welfare and social workers and health care professionals to identify, work with, and prevent girls from being cut. Consistent with international trends in addressing the risks of FGM/C, the paper suggests practice responses for coordinated responses between professionals, communities from practicing countries, and governments of different countries.

    Full Text Available Introduction & Objective: Needlestick and sharps injuries (NSSIs is an important occupational risk among health care workers (HCWs; and it is an important cause of transmission of blood-borne pathogens to this population. The aim of this study was to determine the rate of NSSI among HCWs in the teaching hospitals in Hamadan. Materials & Methods: This cross-sectional study was carried out on 700 HCWs between 2009 and 2010. A questionnaire was designed for data collection. Questionnaires were distributed in 5 hospitals to collect self-reported NSSI in the past 12- months. Results: The rate of accidental NSSI was 24.1% for one year prior the study. Totally, 83.6% of the participants had a full vaccination course against hepatitis B. The majority of NSSIs occurred in the 30-34 age group (33.3% and most of them were female. Also, 48.5% of NSSIs were during blood sampling or IV catheter insertion.Conclusion: Developing appropriate educational programs regarding prophylactic tasks, disposal of medical wastes, and using safe needle devices can reduce the risk of NSSIs among HCWs.

    Full Text Available Health care workers (HCWs constitute a high-risk population of HBV infection. There are limited data on the efficacy of vaccination in HCWs in Egypt.The aim of this study was to evaluate the immune response to hepatitis B recombinant vaccine in HCWs in our hospital. Methods: 100 HCWs who completed three doses of intramuscular immunization with recombinant DNA hepatitis B vaccine (Engerix-B at different time periods during the last 5 years were examined for hepatitis B surface antigen (HBs Ag, anti hepatitis B surface antibodies (anti HBs Abs and hepatitis B core antibodies (HBc Abs.Results: 96% of HCWs showed seroconversion (anti HBs ≥ 10 IU/L; 92% good responders (anti HBs > 100 IU/L and 4% weak responders (anti HBs = 10-100 IU/L. The HBsAg and HBc Ab were never detected among the entire responders. Younger age had higher anti HBs titer than older HCWs. The non responders were 4%; two of them had evidence of chronic hepatitis B infection.Conclusion: Vaccination against HBV in HCWs in Egypt is cost effective and achieved good response rate. Screening for Hepatitis B infection before vaccination should be considered to detect those with undiagnosed infection

    Full Text Available Abstract Background Well-trained and highly motivated community health workers (CHWs are critical for delivery of many community-based newborn care interventions. High rates of CHW attrition undermine programme effectiveness and potential for implementation at scale. We investigated reasons for high rates of CHW attrition in Sylhet District in north-eastern Bangladesh. Methods Sixty-nine semi-structured questionnaires were administered to CHWs currently working with the project, as well as to those who had left. Process documentation was also carried out to identify project strengths and weaknesses, which included in-depth interviews, focus group discussions, review of project records (i.e. recruitment and resignation, and informal discussion with key project personnel. Results Motivation for becoming a CHW appeared to stem primarily from the desire for self-development, to improve community health, and for utilization of free time. The most common factors cited for continuing as a CHW were financial incentive, feeling needed by the community, and the value of the CHW position in securing future career advancement. Factors contributing to attrition included heavy workload, night visits, working outside of one's home area, familial opposition and dissatisfaction with pay. Conclusions The framework presented illustrates the decision making process women go through when deciding to become, or continue as, a CHW. Factors such as job satisfaction, community valuation of CHW work, and fulfilment of pre-hire expectations all need to be addressed systematically by programs to reduce rates of CHW attrition.

    The aim of the study is to supply a contribution to the validity analysis of the Empowering Leadership Questionnaire (ELQ) in the Italian context. The ELQ has been developed in order to measure empowering leadership style in organizational contexts and, in the present work, has been administered to a group of health care workers in order to evaluate the Nurse Manager's leadership style. Three hundred and eleven individuals from an important Local Health Unit of the Veneto Region participated in the study, filling out a self-administered structured questionnaires. Correlations between ELQ, task-oriented, relationship-oriented and transformational leadership stile are addressed. Moreover, the relationships between ELQ, organizational commitment, job burnout, turnover intentions and job satisfaction are analyzed. Exploratory, confirmatory, reliability analyses and path analyses techniques are applied. Results support the main results obtained by the authors of the scale. In addition, with regards to ELQ predictive validity, the selected dependent variables (turnover intentions and job satisfaction) are significantly influenced by some of the ELQ dimensions, via the mediation of affective commitment and job burnout, supporting the value of the ELQ measures in the healthcare context.

    Full Text Available Background: Hepatitis B virus (HBV infection is an endemic infection in Nigeria. Health care workers (HCWs are at risk of occupational exposures to HBV-infected blood and body fluids.Objective: To determine the prevalence and determinants of HBV vaccine coverage among HCWs in two teaching hospitals in Nigeria.Methods: This cross-sectional study was undertaken in 2011 and 2012 in two teaching hospitals in Jos, North-Central Nigeria, and Yenagoa, South-South Nigeria. A self-administered structured questionnaire was administered to HCWs to obtain socio-demographic data and history of HBV vaccination.Results: Out of 290 HCWs who participated in the study, 185 (64.5% had received at least one dose of HBV vaccine; 105 (36.2% had full coverage of three doses. Professional category and previous training in infection control were independently associated with HBV vaccination. House officers and laboratory scientists were more likely to be unvaccinated than resident doctors, consultant doctors and nurses. Full vaccine coverage was associated with younger age and shorter years of professional experience.Conclusion: We observed a generally low rate of HBV vaccine coverage among HCWs in Nigeria. Establishment of policies on compulsory HBV vaccination of all HCWs in Nigeria is recommended.

    Full Text Available OBJETIVO: Avaliar as alterações auditivas periféricas em um grupo de trabalhadores exposto a inseticidas, organofosforados e piretróides, utilizados em campanhas de controle de vetores. MÉTODOS: Estudo de prevalência de uma população de 98 indivíduos que pulverizavam venenos nas campanhas de prevenção do dengue, da febre amarela e da doença de Chagas. A amostra foi de tipo finalística, considerando o universo dos trabalhadores de um distrito sanitário, em Pernambuco, no ano de 2000. Utilizou-se questionário contendo questões de identificação de riscos ocupacional e não ocupacional, medidas de segurança utilizadas, antecedentes de problemas auditivos e sintomas referidos. Foi investigada a historia pregressa de exposição ao ruído, por ser um fator de confusão para a perda auditiva. Todos os indivíduos foram avaliados pelo teste de audiometria tonal. RESULTADOS: Dos expostos apenas aos inseticidas, 63,8% apresentaram perda auditiva. Para o grupo com exposição concomitantemente aos inseticidas e ao ruído, a perda auditiva foi de 66,7%. O tempo mediano para o desenvolvimento de alterações auditivas nas freqüências médias altas, para as exposições combinadas de inseticidas e ruído, foi de 3,4 anos e para as exposições apenas aos inseticidas foi de 7,3 anos. A perda auditiva para as exposições concomitantes aos dois fatores foi de maior intensidade nessas freqüências, do que o observado na exposição apenas aos inseticidas. CONCLUSÕES: Há evidência de que a exposição aos inseticidas induz dano auditivo periférico e que o ruído é um fator que interage com os inseticidas, potencializando seus efeitos ototóxicos. Faz-se necessário avaliar essa possível associação através de estudos epidemiológicos de caráter analítico.OBJECTIVE: To examine the peripheral auditory disorders in a group of workers exposed to organophosphate and pyrethroid insecticides, used in vector control campaigns.

    Full Text Available Cardiotoxicity is an important side effect of cytotoxic drugs and may be a risk factor of long-term morbidity for both patients during therapy and also for staff exposed during the phases of manipulation of antiblastic drugs. The mechanism of cardiotoxicity studied in vitro and in vivo essentially concerns the formation of free radicals leading to oxidative stress, with apoptosis of cardiac cells or immunologic reactions, but other mechanisms may play a role in antiblastic-induced cardiotoxicity. Actually, some new cytotoxic drugs like trastuzumab and cyclopentenyl cytosine show cardiotoxic effects. In this report we discuss the different mechanisms of cardiotoxicity induced by antiblastic drugs assessed using animal models.

    Cytogenetic studies of clinically healthy workers employed in the rubber industry showed an increase in chromosome aberrations (CAs), sister-chromatid exchanges (SCEs) and a decrease in proliferation indices (PIs). The aim of the present study was to establish, using the SCE and PI tests, genotoxic effects of hazardous chemicals in the rubber industry. An increase in mean SCEs in the lymphocytes of vulcanizers as compared to controls was observed. Since the PI in the exposed group was insignificantly decreased as compared to the controls, it could be concluded that the SCE test is the most sensitive cytogenetic test for the detection of a genotoxic effect of chemicals in the rubber industry. There was no evidence in the present study that the genotoxic effect of chemicals in the rubber industry was enhanced by cigarette smoking. PMID:7688857

    Objective To explore the semen quality of the workers exposed to the xenoestrogen bisphenol A( BPA) was explored. Methods A cross-sectional study of 20 BPA exposed and 16 control workers with similar age,physical activities was performed. Tests included quantifying BPA in blood samples and investigating the quantity and quality of semen. Semen parameters were determined with the method recommended by WHO. Results 94.4% exposed workers were found BPA in blood, and the median was 101.94 μg/L However, only 18.8% control subjects were found BPA in blood, and the median level was 0 μg/L. The sperm density of exposed workers [(68.65±44.00)×10~6/ml] was significantly lower than that of control [(118.56±98.36 )×l0~6/ml]. Relationship analysis showed the positive relationships (r=0.44, P<0.01) between the sperm with quick forward progression and BPA level in blood, negative relationships between the percentage of normal sperm and BPA level in blood (r=-0.62,P=0.01). Conclusion BPA could affect the sperm density, and may influence the semen quality.

  19. Publication of new results from the INWORKS epidemiological study about the risk of cancer among nuclear industry workers chronically exposed to low ionizing radiation doses

    International Nuclear Information System (INIS)

    In this cohort study, 308297 workers in the nuclear industry from France, the United Kingdom, and the United States with detailed monitoring data for external exposure to ionising radiation were linked to death registries. Excess relative rate per Gy of radiation dose for mortality from cancer was estimated. Follow-up encompassed 8.2 million person years. Of 66632 known deaths by the end of follow-up, 17?957 were due to solid cancers. Results suggest a linear increase in the rate of cancer with increasing radiation exposure. The average cumulative colon dose estimated among exposed workers was 20.9 mGy (median 4.1 mGy). The estimated rate of mortality from all cancers excluding leukaemia increased with cumulative dose by 48% per Gy (90% confidence interval 20% to 79%), lagged by 10 years. Similar associations were seen for mortality from all solid cancers (47% (18% to 79%)), and within each country. The estimated association over the dose range of 0-100 mGy was similar in magnitude to that obtained over the entire dose range but less precise. Smoking and occupational asbestos exposure are potential confounders; however, exclusion of deaths from lung cancer and pleural cancer did not affect the estimated association. Despite substantial efforts to characterise the performance of the radiation dosimeters used, the possibility of measurement error remains. The study provides a direct estimate of the association between protracted low dose exposure to ionising radiation and solid cancer mortality. Although high dose rate exposures are thought to be more dangerous than low dose rate exposures, the risk per unit of radiation dose for cancer among radiation workers was similar to estimates derived from studies of Japanese atomic bomb survivors. Quantifying the cancer risks associated with protracted radiation exposures can help strengthen the foundation for radiation protection standards

    Full Text Available Purpose—is to investigate a shift sequence-based approach efficiency then problem consisting of a high number of shifts.Research objectives:• Solve health care workers rostering problem using a shift sequence based method.• Measure its efficiency then number of shifts increases.Design/methodology/approach—Usually rostering problems are highly constrained. Constraints are classified to soft and hard constraints. Soft and hard constraints of the problem are additionally classified to: sequence constraints, schedule constraints and roster constraints. Sequence constraints are considered when constructing shift sequences. Schedule constraints are considered when constructing a schedule. Roster constraints are applied, then constructing overall solution, i.e. combining all schedules.Shift sequence based approach consists of two stages:• Shift sequences construction,• The construction of schedules.In the shift sequences construction stage, the shift sequences are constructed for each set of health care workers of different skill, considering sequence constraints. Shifts sequences are ranked by their penalties for easier retrieval in later stage.In schedules construction stage, schedules for each health care worker are constructed iteratively, using the shift sequences produced in stage 1.Shift sequence based method is an adaptive iterative method where health care workers who received the highest schedule penalties in the last iteration are scheduled first at the current iteration.During the roster construction, and after a schedule has been generated for the current health care worker, an improvement method based on an efficient greedy local search is carried out on the partial roster. It simply swaps any pair of shifts between two health care workers in the (partial roster, as long as the swaps sa
