Objectives To examine the relationship between occupation and blood lead levels in pregnant women of Durango, Mexico. Method A cross sectional study was conducted with 299 pregnant women. Information on occupation, risk factors and sociodemographic data was collected by means of a structured questionnaire. Blood lead concentration was tested by graphite furnace spectrometry. Women were divided into three groups according to occupation: working in places with potential source of lead exposure (exposed group), working in places without lead exposure (control group I), and non-working women (control group II). The X 2 test was used to assess statistical differences between the groups, and one way ANOVA was applied for comparisons. Logistic regression was performed using blood lead < 5 mg/dL or ≥ 5 mg/dL as dependent variable, and ajdusted for jurisdiction, income, gestational age, and abortions. Results Only 24(8%) women worked in places with potential source of lead exposure, 47(15.7%) worked in other places, and 228(76.3%) did not have a remunerated job. Mean blood lead concentration in the study sample was 2.79 mg/dL. However, blood lead ≥ 5 mg/dL accounted for 25% of exposed women, 2.1% of control group I, and 6% of control group II (X 2 = 13.04; p .001). Mean blood lead level was 4.24 mg/dL in the exposed group, 2.31 mg/dL in the control group I, and 2.74 mg/ dL in the control group II; those differences were statistically significant (0.001). Logistic regression confirmed that blood lead ≥ 5 mg/dL is associated with occupational exposure (p = 0.036). Conclusions Our findings suggest that surveillance for occupational exposure to prevent health damages during pregnancy is needed. 0243 SCREENING AND DISABILITY PREVENTION FOR MUSCULOSKELETAL DISORDERS OF HIGH-TECH INDUSTRY WORKERS IN TAIWANYa-Yuan Hsu. Institute of Occupational Safety and Health, Taipei, Taiwan 10. 1136/oemed-2014-102362.287 Objectives In Taiwan, 40-60% of the working population is affected by musculoskelet al disorders (MSD). MSD may lead to reduced productivity, decreased work ability, and even disability. The aim of this study was to describe the effects about occupational health medical team preventing and management of MSD. Method The design was prospective study describing the hightech industry workers screening and disability prevention for MSD. The quantitative analysis of the questionnaire was conducted through descriptive statistics and pair-t test in order to indicate the direction and relationship between the two sets of occupational health medical team intervention program. Results Of the 386 high-tech industry workers who completed the questionnaire. The use of pair-t test comparing two months of occupational health medical program, individual symptom scores significantly decreased 1.99 points to 6.12 points. The degree of functional subjects increased from 57% to 74%, a significant improvement. Work ability index before treatment was 38.49 to 39.36 points after treatment improved, particularly in the self-evaluation and self-ab...

Relación heterófilo/linfocito, frecuencia espontánea de eritrocitos micronucleados y prolongaciones nucleares en el ganso nevado (Chen caerulescens): Una propuesta como posible biomonitor de estrés y genotóxicos ambientalesHeterophil to lymphocyte ratio, basal frequency of micronucleated erythrocytes and nuclear extensions in the snow goose (Chen caerulescens):A proposal as possible stress and environmental genotoxicity biomonitor ResumenExisten organismos silvestres que son altamente vulnerables ante estresores antropogénicos y naturales, estos organismos pueden ser de utilidad para evaluar la salud ambiental mediante diferentes indicadores confiables, sencillos, rápidos, económicos para determinar y si es posible reducir estos efectos negativos. En este estudio proponemos al ganso nevado (Chen caerulescens) como posible biomonitor de estrés y genotóxicos ambientales mediante la relación heterófilo/linfocito (h/l), la prueba de micronúcleos (emn), prolongaciones nucleares en eritrocitos (epn) y eritrocitos policromáticos (epc). Durante la temporada de caza (2012-2013) en el humedal de Málaga, Durango, México, colectamos 18 organismos. Los eritrocitos fueron las células más abundantes, de núcleo y morfología elípticos, de tamaño 12.68 ± 0.89 µm. Observamos heterófilos (11.07±1.32 µm), eosinófilos (9.67±1.26 µm), basófilos (5.75 ± 0.78 µm), monocitos (10.49±1.36 µm) y linfocitos (6.53±1.0 µm). No identificamos alteración en las proporciones ni en la morfología de leucocitos, sin embargo, es necesario un mayor número de organismos para establecer los parámetros sanguíneos de base normal para esta especie. La relación h/l fue de 0.41 ± 0.11 este valor es similar a lo reportado para esta y otras especies de aves consideradas como sanas. Establecimos la frecuencia basal de emn (2.6±1.45), epn (249.2 ± 89.74) y epc (156.5 ± 50). El ganso nevado es un organismo que se perfila como buen candidato a biomonitor ambiental debido a la frecuencia basal de su re lación h/l, emn, epn y epc, pero debe probarse en condiciones estandarizadas y a través de estudios en zonas con y sin contaminación.Palabras clave: Biomonitor, Chen caerulescens, eritrocitos micronucleados, eritrocitos con prolongaciones nucleares, índice heterófilo linfocito. AbstractThere are wild organisms that are highly vulnerable to anthropogenic and natural stressors, these organisms may be useful to assess environmental health through various reliable, simple, rapid, inexpensive indicators and to determine and if possible reduce these negative effects. In this study we propose that the snow goose (Chen caerulescens) to be tested as stress and environmental biomonitor of genotoxicity, by heterophil/lymphocyte (h/l) ratio, micronucleus test (mne), nuclear protrusions in erythrocytes (npe) and polichromatic erythrocytes (pce). During the hunting season (2012)(2013) in the wetland of Malaga, Durango, Mexico, 18 organisms were collected. Erythrocytes were the most abundant cells with elliptical morphology and nucleus, size of 12.68 ± 0.89, regular contour and nuc...
